INTESTINAL HEALTH PROMOTING COMPOSITIONS

GOVERNMENT INTEREST

A portion of the research for this invention was made with government support under a grant awarded by the National Institute of Food and Agriculture. The government has certain rights in the invention.

BACKGROUND

The gastrointestinal system is a complex network of tissues, organs, host cells, and bacterial cells. Aging, diets, medications, disruptions in the intestinal microbiota, and an individual's lifestyle conditions can negatively affect this network. These effects can include disrupting the balance of the gut microbiota, increased inflammation in the gastrointestinal tissues, and a disruption in the epithelial cell barrier of the gastrointestinal system. These effects can ultimately lead to systemic issues. Formulation and methods that promote and restore intestinal health would provide a benefit.

DETAILED DESCRIPTION

Before invention embodiments are disclosed and described, it is to be understood that no limitation to the particular structures, process steps, or materials disclosed herein is intended, but also includes equivalents thereof as would be recognized by those ordinarily skilled in the relevant arts. It should also be understood that terminology employed herein is used to describe particular examples only and is not intended to be limiting. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. In the specification and the appended claims, the singular forms include plural referents unless the context clearly dictates otherwise.

As used herein, the singular forms "a," "an," and "the" specifically provide express support for plural referents, unless the content clearly dictates otherwise. For example, "a prebiotic fiber" provides support for one or more prebiotic fibers.

The term "about" is used herein refers to a degree of deviation. It means

approximately, in the region of, roughly, or around. When the term "about" is used in conjunction with a numerical range, it modifies that range by extending the boundaries slightly above and slightly below the numerical values set forth. It is understood that support in this specification for numerical values used in connection with the term "about" is also provided for the exact numerical value itself as though "about" were not used.

Concentrations, amounts, and other numerical data may be expressed or presented herein in a range format. It is to be understood that such a range format is used merely for convenience and brevity and thus should be interpreted flexibly to include not only the numerical values explicitly recited as the limits or endpoints of the range, but also to include all the individual numerical values and/or sub-ranges encompassed within that range as if each numerical value (including fractions) and sub-range is explicitly recited. As an illustration, a numerical range of "about 1 to about 5" should be interpreted to include not only the explicitly recited values of about 1 to about 5, but also include individual values and sub-ranges within the indicated range. Thus, included in this numerical range for example, are individual values such as 2, 2.6, 3, 3.8, and 4 and sub-ranges such as from 1-3, from 2-4, and from 3-5, etc., as well as 1, 2, 3, 4, and 5, individually.

As used herein a "concentrate" refers to an extract of a source that contains at least the same amount of active fractions, compounds, or other constituents, in a smaller volume than in the source itself. In one example, a "concentrate" may be a dried powder derived from a component that does not include the use of any solvents during the concentration process.

Comparative terms such as "more effectively," "greater than," "improved,"

"enhanced," and like terms can be used to state a result achieved or property present in a formulation or process that has a measurably better or more positive outcome than the thing to which comparison is made. In some instances comparison may be made to the prior art or to the status of a property before administration of a formulation or method that results in the more positive outcome.

As used herein, "comprises," "comprising," "containing," and "having" and the like can have the meaning ascribed to them in U.S. Patent law and can mean "includes,"

"including," and the like, and are generally interpreted to be open ended terms. The terms "consisting of or "consists of are closed terms, and include only the components, structures, steps, or the like specifically listed in conjunction with such terms, as well as that which is in accordance with U.S. Patent law. "Consisting essentially of or "consists essentially of have the meaning generally ascribed to them by U.S. Patent law. In particular, such terms are generally closed terms, with the exception of allowing inclusion of additional items, materials, components, steps, or elements, that do not materially affect the basic and novel characteristics or function of the item(s) used in connection therewith. For example, trace elements present in a composition, but not affecting the composition's nature or

characteristics would be permissible if present under the "consisting essentially of language, even though not expressly recited in a list of items following such terminology. When using an open ended term in the written description, like "comprising" or "including," it is understood that direct support should be afforded also to "consisting essentially of language, as well as, "consisting of language as if stated explicitly and vice versa.

The term "dosage unit" is understood to mean a single unit of composition which is capable of being administered to a subject or patient, to provide an amount of an active agent sufficient to achieve, or contribute to, a therapeutic effect to be achieved. In some embodiments, a "dosage unit" is a unit and that may be readily handled and packed, remaining as a physically and chemically stable unit dose comprising either the active ingredient as such or a mixture of it with solid or liquid pharmaceutical vehicle materials. Moreover, "dosage" and "dose" can refer to such a dosage unit. Alternatively, a "dosage" or "dose" can encompass multiple dosage units which collectively provide a desired amount of active agent to be administered to a subject at a singular point in time. Multiple doses or dosages can be utilized according to a schedule in order to establish a dosing regimen.

The phrase "effective amount," "therapeutically effective amount," or "therapeutically effective rate(s)" of an active ingredient refers to a non-toxic, but sufficient amount or delivery rates of the active ingredient, to achieve therapeutic results in treating a disease or condition for which the active agent is being delivered. It is understood that various biological factors may affect the ability of a substance to perform its intended task. Therefore, an "effective amount," "therapeutically effective amount," or "therapeutically effective rate(s)" may be dependent in some instances on such biological factors. Further, while the achievement of therapeutic effects may be measured by a physician or other qualified medical personnel using evaluations known in the art, it is recognized that individual variation and response to treatments may make the achievement of therapeutic effects a subjective decision. The determination of a therapeutically effective amount or delivery rate is well within the ordinary skill in the art of pharmaceutical sciences and medicine.

The term "extract" refers to those substances prepared using a solvent, e.g., ethanol, water, steam, superheated water, methanol, hexane, chloroform liquid, liquid C0 ₂ , liquid N _2, propane, supercritical C0 ₂ , or any combination thereof. Extracts, as used herein, can refer to an extract in a liquid form, or can refer to a product obtained from further processing of the liquid form, such as a dried powder or other solid form. Extracts may take many forms including but not limited to: solid, liquid, particulate, chopped, distillate, etc. and may be performed by any number of procedures or protocols, such as chopping, grinding,

pulverizing, boiling, steaming, soaking, steeping, infusing, applying a gas, etc., and may employ any suitable reagents, such as water, alcohol, steam, or other organic materials.

Extracts typically have a given purity percentage and can be relatively to highly pure. In some embodiments, extracts can be phytoextracts made from specific parts of a source, such as the skin, pulp, leaves, flowers, fruits, kernels, seeds, of a plant etc., or can be made from the whole source. In some aspects, an extract may include one or more active fractions or active agents. In some aspects, the purity of an extract can be controlled by, or be a function of the extraction process or protocol.

As used herein, "formulation" and "composition" can be used interchangeably and refer to a combination of at least two ingredients. In some embodiments, at least one ingredient may be an active agent or otherwise have properties that exert physiologic activity when administered to a subject.

Formulation or compositional ingredients included or recited herein are to be presumed to be in wt% unless specifically stated otherwise. In addition, ingredient amounts presented in the form of ratios are to be presumed to be in wt% (e.g. %w/w) ratios.

The phrase, "intestinal hypermeability" refers to a higher than normal (i.e. higher than that of an average subject) permeability of the gastrointestinal system and can in some instances refer to increased permeability in the stomach, small intestines and/or large intestines.

As used herein, "linear inhibitory effect" or "dose-response" refers to a linear decrease in secretion or biosynthesis resulting from all concentrations of the inhibiting material over a dose-response curve. For example, inhibition at low concentrations followed by a failure of inhibition or increased secretion at higher concentrations represents a lack of a linear inhibitory effect.

The term "or" is used in the "inclusive" sense of "and/or" and not the "exclusive" sense of "either/or."

As used herein, "pharmaceutically acceptable" refers generally to materials, which are suitable for administration to a subject in connection with an active agent or ingredient. For example, a "pharmaceutically acceptable carrier" can be any substance or material that can be suitably combined with an active agent to provide a composition or formulation suitable for administration to a subject. Excipients, diluents, and other ingredients used in or used to prepare a formulation or composition for administration to a subject can be used with such term.

The term "prevent" and its variants refer to prophylaxis against a particular undesirable physiological condition. The prophylaxis may be partial or complete. Partial prophylaxis may result in the delayed onset of a physiological condition. An individual skilled in the art will recognize the desirability of delaying onset of a physiological condition, and will know to administer the compositions of the invention to subjects who are at risk for certain physiological conditions in order to delay the onset of those conditions. For example, the person skilled in the art will recognize that obese subjects are at elevated risk for coronary artery disease. Thus, the person skilled in the art will administer compositions of the invention in order to improve the gut microbiota in an obese individual.

As used herein, a "subject" refers to an individual receiving treatment. In one aspect, a subject can be a mammal. In another aspect, a subject can be a human. In another aspect, the subject can be a domesticated animal or livestock.

As used herein, "substantial," or "substantially," when used in reference to a quantity or amount of a material, an effect, or a specific characteristic of a composition thereof, refers to an amount that is sufficient to provide an effect that the material or a characteristic the material was intended to provide. The exact degree of deviation allowable may in some cases depend on the specific context. Similarly, "substantially free of or the like refers to the lack of an identified element or agent in a composition. Particularly, elements that are identified as being "substantially free of are either completely absent from the composition, or are included only in amounts which are small enough so as to have no measurable effect on the composition.

As used herein, the term "insignificant" or "clinically insignificant" refers to the extent of an effect of administering a composition to a subject. For example, if the extent of the result does not cause a clinical change in the subject, then the result is clinically insignificant.

The terms "treat," "treating," or "treatment" as used herein and as well understood in the art, mean an approach for obtaining beneficial or desired results, including without limitation clinical results in a subject being treated. Beneficial or desired results can include, but are not limited to, alleviation or amelioration of one or more signs or symptoms of a condition, diminishment of extent of disease, stabilizing (i.e. not worsening) the state of a disease or condition, delaying or slowing of disease progression, amelioration or palliation of the disease state, diminishment of the reoccurrence of disease, and remission (whether partial or total), whether detectable or undetectable. "Treat," "treating" and "treatment" can also mean prolonging survival as compared to expected survival if not receiving treatment and can be prophylactic. Such prophylactic treatment can also be referred to as prevention or prophylaxis of a disease or condition. The prophylaxis may be partial or complete. Partial prophylaxis may result in the delayed onset of a physiological condition.

As used herein, the term "solvent" refers to a liquid of gaseous, aqueous, or organic nature possessing the necessary characteristics to extract solid material from a plant product. Examples of solvents would include, but not limited to, water, steam, superheated water, methanol, ethanol, ethyl acetate, hexane, chloroform, liquid C0 ₂ , liquid N ₂ , propane, or any combinations of such materials.

As used herein, a plurality of items, structural elements, compositional elements, and/or materials may be presented in a common list for convenience. However, these lists should be construed as though each member of the list is individually identified as a separate and unique member. Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary.

Any steps recited in any method or process claims may be executed in any order and are not limited to the order presented in the claims unless otherwise stated.

The gastrointestinal system is a tract of connected and related structures that are involved in the digestion of food and absorption of energy and nutrients. The gastrointestinal tract, shown in FIG. 1, consists of all the structures between the mouth and the anus. The whole gastrointestinal tract is about nine meters long and can be divided into an upper gastrointestinal tract and a lower gastrointestinal tract. The lower gastrointestinal tract includes the small intestine and the large intestine. The small intestine is about 20 feet in length and has a highly folded structure that includes finger like protections called villi. Within the villi is a single layer of epithelial cells and a layer of capillaries. The main function of the small intestine is to absorb products of digestion. Nutrients can pass through the layer of epithelial cells and enter the capillaries underneath. These nutrients can eventually enter larger blood vessels and travel to the liver where they are processed and regulated for release into the body. The large intestine is about 3 feet long and is used to collect the solid material that was not digested in the small intestine and to absorb water. The large intestine is loaded with bacteria that synthesize vitamins.

As previously mentioned, the small intestine has a barrier composed of a single layer of epithelial cells. These epithelial cells are sealed by tight junctions. The tight junctions can modulate intestinal permeability by regulating paracellular transport of water and ions and the transcellular pathway. See, FIG. 3. In addition to being responsible for absorption of nutrients, this cell layer also plays a role in maintaining the mucosal immune homeostasis, preventing inflammation, and constitutes the first line of defense against the entry of noxious bacteria/bacterial toxins and/or other antigens that can initiate chronic inflammation. Any bacteria, bacterial toxins, antigens, water, and ions that pass through this cell layer can enter the blood stream, affect other organs, and can have systemic effects on the individual overall. See, FIG. 4. Lifestyle and dietary factors such as high-intensity exercise, high-fat diets, and over nutrition can also influence intestinal permeability and can play a role in increasing toxin permeability across tight junctions and into circulation.

Disruption of the tight junction results in a leaky tight junction barrier and can lead to an increase in intestinal permeability. Increased permeability can be a major factor in the pathophysiology of several inflammation and obesity related pathologies. Low levels of chronic inflammation can negatively affect intestinal barrier permeabilization.

Tumor necrosis factor alpha (T Fa) can also be a central underlying mediator. T Fa triggers apoptosis; however, these changes in distribution occur through its capacity to promote barrier permeabilization and expression of select tight junction proteins. Ultimately, TNFa can play a role in promoting tight junction barrier dysfunction. Loss of tight junction functionality and increased intestinal permeability can be contributors to the pathology of allergies (e.g. celiac disease), inflammatory bowel diseases (Crohn's disease and ulcerative colitis), food intolerances, dyspepsia, low levels of chronic intestinal inflammation (e.g. those associated with obesity and type I and II diabetes), insulin resistance, autism, multiple sclerosis, malnutrition, metabolic syndrome, cancer, asthma, atopy, and rheumatoid arthritis.

Another factor in the health of an individual's gastrointestinal system is the microbiota of the gut. The microbiota is a complex network of bacteria, archae, viruses, and eukarya that influence an individual's health and physiology. The gastrointestinal microbiota has been estimated to reach approximately 3.9 x 10 ¹³ microorganisms The composition of an individual's microbiota can vary greatly in numbers, diversity, histology, and activities. The richness and diversity of the gut microbiota has been shown to be significantly influenced by antibiotics, age, diet, ethnicity, geographical location, physiological stress, psychological stress, and sex.

Alterations in the gut microbiota can cause an increase in endotoxin production. A microbiota that has few and less diverse beneficial bacteria and has greater numbers and more diverse non-beneficial bacteria can occur with age and/or conditions associated with accelerated aging, such as, obesity or a high fat diet. An imbalance of the microbiota can also lead to increased inflammation of the gastrointestinal lining, changes in the integrity of the intestinal cell wall, and can led to gut permeability. These changes can contribute to the incidence of gastrointestinal infections, asthma/atopy, obesity, metabolic syndrome, cancer, rheumatoid arthritis, Crohn's disease, and ulcerative colitis. In contrast, a balanced and diverse microbiota can provide resistance to infections, allow for healthy aging, prevent intestinal disorders, contribute to polyphenol metabolism, and can generate absorbable bioactives. The gut microbiome can also play a role in metabolism, immune development, endocrine signaling, and neurologic signaling.

Flavonoids can play an important role in the prevention and amelioration of intestinal barrier permeabilization. The microbiota in the gut can metabolobize flavoinoids releasing absorbable bioactives. These bioactives can restore maintain and/or restore the nutrient balance. Accordingly, flavonoids have the capacity to inhibit inflammation, modulate select signaling cascades, and regulate cellular redox status. However, the large number of existing flavonoids with different chemical/spatial structures, and the multiple metabolites generated at the large intestine by the microbiota, rule out the possibility of simple generalizing the health benefits and mechanisms of action of flavonoids as a class.

Anthocyanins (AC) constitute one of the major flavonoid subgroups, which are present and provide color to many fruits and vegetables (e.g. berries, red cabbage, black rice). Several different AC exist, differing in the number and substitution of hydroxyl groups, the bonded sugar moieties, carboxylates type, and bonding to sugars. A portion of the different classes of anthocyanins includes: cyanidins, delphinidins, peonidins, petunidins, and

malvidins.

Current evidence indicates that parental AC are present throughout the length of the gastrointestinal tract. At the colon, AC's can be metabolized by microorganisms in the gut to several metabolites. Thus, in theory, the small intestine and to a lesser extent the large intestine can be exposed to significant amounts of dietary parental AC. Despite the potential for benefits of dietary AC on the gastrointestinal system, the particulars under conditions of increased intestinal permeability, are mostly unknown. AC could exert beneficial effects at the gastrointestinal tract through direct and indirect effects. The indirect effects can be related to the potential capacity of AC to modulate the microbiota, affecting microbiota-mediated AC metabolism. Both a "healthier" microbiota and the formation of select active metabolites could in turn mediate AC indirect effects on intestinal health and lead to systemic effects.

Reference is made hereinafter in detail to specific embodiments of the invention.

While the invention will be described in conjunction with these specific embodiments, it will be understood that it is not intended to limit the invention to such specific embodiments. On the contrary, it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail, in order not to unnecessarily obscure the present invention.

The present disclosure relates to compositions and methods for improving intestinal health in a subject. In one example, an intestinal health promoting composition is presented. The composition can include a combination of cyanidins and delphinidins (classes of anthocyanins), in an amount sufficient to treat intestinal hyperpermeability. In one example, the cyanidins and the delphinidins can be collectively present in an amount that maintains tight junction integrity in the intestinal epithelial cells. In another example, the cyanidins and the delphinidins can be collectively present in an amount that restores tight junction integrity in the intestinal epithelial cells.

Cyanidins and delphinidins can protect intestinal epithelial cells against TNFa including loss of monolayer permeability in transepithelial electrical resistance (TEER) and increased paracellular transport of FITC-dextran. In contrast, malvidin, peonidin, and petunidin do not seem to provide protective actions to intestinal epithelial cells against TNFa induced TEER permeability and do not seem to increase paracellular transport of FITC- dextran. Without being bound by theory the protective effects of the cyanidins and delphinidins, may be due to the presence of a catechol group on the B-ring of the cyanidins and delphinidins. The anthocyanins that the present inventors tested which did not incorporate the B-ring did not exhibit these protective effects. In one example, this activity can be selective. In another example, the protective function can be dose dependent.

In another example, the present disclosure provides, a method of treating a condition or disorder related to gastrointestinal health in a subject comprising maximizing tight junction integrity in epithelial cells of gastrointestinal tract of the subject. In another example, a method of maximizing tight junction integrity in epithelial cells of the gastrointestinal tract of a subject is presented. In yet another example the present disclosure provides, a method of treating intestinal hyperpermeability. In some examples, these methods can be targeted to (i) maintain and/or create a healthy microbiome in the gastrointestinal system, (ii) maintain and/or create an inflammatory balance within the gastrointestinal system, and/or (iii) maintain and/or form intestinal cell barrier integrity. In some embodiments, an intestinal health promoting composition can include cyanidins, delphinidins, or a combination thereof, and in some embodiments, these agents can be present in a therapeutically effective amount. In one example, the composition can include a combination of cyanidins and delphinidins in an amount sufficient to treat intestinal hyperpermeability. In one example, the cyanidins and the delphinidins can be collectively present in an amount that maintains intestinal permeability. In another example, the cyanidins and the delphinidins can be collectively present in an amount that reduces intestinal hyperpermeability. In yet another example, the cyanidins and delphinidins can be capable of impacting the microbiome and can be capable of providing anti-inflammatory properties.

The amount of cyanidins and delphinidins can vary in the composition. In one example, the cyanidins and the delphinidins can individually or collectively range from about 5 wt% to about 50 wt% of the composition, or an active fraction of the composition. In another example, the cyanidins and the delphinidins can individually or collectively range from about 12 wt % to about 45 wt% of the composition, or an active fraction of the composition. In a further example, the cyanidins and delphinidins can individually or collectively range from about 12 wt% to about 25 wt% of the composition or an active fraction of the composition.

The cyanidins and delphinidins can be derived from various sources. In one example, a source of at least one of the cyanidins and the delphinidins can be derived from a black rice component, a blueberry component, a black current component, a crowberry component, a bilberry component, a black chokeberry component, or a combination thereof. In another example, the source of the cyanidins and the delphinidins can be derived from the black rice component, the blueberry component, and the black current component. In yet another example, the source of the cyanidins and the delphinidins can be derived from the black rice component and the bilberry component. In a further example, the source of the cyanidins and the delphinidins can be derived from the black current component and the blueberry component. In another example, the cyanidins and delphinidins can be artificially created or synthesized (e.g. "synthetic").

In one example, the composition can include a black rice component. The black rice component can be derived from black rice kernels, black rice concentrate, black rice extract, black rice powder, or a combination thereof. In one example, the black rice component can be a black rice extract. For example, a liquid rice extract can be obtained by concentrating black rice kernels and passing the concentrated black rice kernels through a resin absorption (chromatography column). In one example, the solvents can be water and ethanol. In one example, the column can be eluted with a 70 wt% ethanol and 30 wt% water solution. In another example, the column can be eluted with 75 wt% ethanol and a 25 wt% water solution. The eluent can then be concentrated into a concentrated liquid extract, dried, and packaged. In another example, the black rice extract can be derived from black rice kernels. In one example, the black rice can be derived from Oryza sativa L.

In one example, the black rice extract can make-up about 2.5 wt% to about 20 wt% of the composition, or an active fraction of the composition. In another example, the black rice component can be present from about 10 wt% to about 15 wt% of the composition, or an active fraction of the composition. In a further example, the black rice extract can be present from about 2.5 wt% to about 5 wt% of the composition, or an active fraction of the composition. In yet another example, the black rice component can be present from about 2.5 wt% to about 7.5 wt% of the composition, or an active fraction of the composition.

In one example, the black rice component can have standardized anthocyanin content.

In another example, the black rice component can have a standardized anthocyanin content of about 20 wt%. In a further example, the black rice component can have a standardized anthocyanin content of about 25 wt%. In one example, the standard anthocyanin content can be measured by HPLC. In another example, the standard anthocyanin content can be measured by UV.

In another example, the composition can include the blueberry component. The blueberry component can include a member selected from the group consisting of blueberry fruit, blueberry extract, blueberry concentrate, blueberry juice, blueberry powder, or a combination thereof. In one example, the blueberry component can be a blueberry powder. In another example, the blueberry component can be a blueberry juice. In yet another example, the blueberry component can be a blueberry powder derived from blueberry juice. In a further example, the blueberry component can be blueberry extract. For example, a blueberry fruit extract can be obtained by extracting the blueberry fruit with water. The extraction can be filtered and the filtrate can then be washed with water and parsed with 75% ethanol thru resin adsorption. The extract can then be concentrated under vacuum pressure and spray dried. The concentrated extract was then grinded, sieved, and packaged. In one example, the blueberry component can be a bog blueberry component. In one example, the blueberry component can be derived from Vaccinium uliginosum L. In one example, the blueberry component can range from about 1 wt% to about 30 wt% of the composition or an active fraction of the composition.

In another example, the blueberry component has a standardized anthocyanin content ranging from about 0.5 wt% to about 5 wt%. In yet another example, the blueberry component can have a standardized anthocyanin content ranging from about 20 wt% to about 30 wt%. In a further example, the blueberry component can have a standardized anthocyanin content of about 25 wt%. In yet another example, the blueberry component can have a standardized anthocyanin can be about 17% as measured by UV or about 25% as measured by HPLC.

In one example, the composition can include the black current component. In one example, the black current component can include black current fruit, black current extract, black current concentrate, black current juice, black current powder, or a combination thereof. In another example, the black current component can be a black current powder. In yet another example, the black current component can be a black current juice. In a further example, the black current component can be a black current extract. In one example, the black current extract can be extracted using water, a resin exchange, and ethanol. In one example, the black current can be an ethylene oxide free product. In one example, the black current component can be a derived from Ribes nigrum.

In another example, the condition can be peripheral insulin resistance and the method can reduce peripheral insulin resistance. In another example, the condition or disorder can be type I diabetes or type II diabetes. In yet another example, the condition or disorder can be a nitric oxide related disorder, expression of iNOS, expression of COX-2, NADPH oxidase, or a combination thereof. In one example, the condition or disorder can stem from pathogens, antigens, and pro-inflammatory factors that can pass through the tight junctions.

In another example, the method can include optimizing a balance of gut microbiota in the gastrointestinal tract. In one example, optimizing the balance of gut microbiota can include increasing commensal bacteria levels in the gastrointestinal tract when compared to levels of commensal bacteria in the gastrointestinal tract prior to administering the method. In another example, the commensal bacteria can belong to bifidobacteria genus. In one example, the commensal bacteria can belong to bacteroidetes phylum. In another example, the commensal bacteria can be bacterdies caccae, bacteriodes uniformis, or a combination thereof. In yet another example, the increase in the commensal bacteria after 8 weeks of daily administering the method to the subject can be at least 20%. In another example, the increase in commensal bacteria after 8 weeks of daily administering the method to the subject can be about 5%, can about 10%, can be about 15%, or can be about 25%.

In one example of the method, optimizing the balance of gut microbiota can include increasing diversity of bacteria when compared to the diversity of bacteria present in the gut prior to administering the method. In one example, the diversity of bacteria can include at least 200 strains. In another example, the method can include decreasing harmful gut bacteria when compared to a level of harmful gut bacteria present prior to administering the method. In one example, the harmful gut bacteria can include firmicutes. In some studies firmicutes have been found to make up a higher portion of the gut microbiome in obese individuals. In yet another example, the decreasing of the firmicutes after 8 weeks of daily administering the method to the subject can be greater than a 15% reduction in firmicutes levels. In a further example, the decreasing of the firmicutes after 8 weeks of daily administering the method to the subject can be greater than a 5% reduction, about a 10% reduction, about a 12% reduction, about a 15% reduction, or about a 20% reduction.

In one example, the method can include optimizing the gut microbiota by altering the firmicutes:bacteriodetes ratio. In one example, the ratio of firmicutes:bacteriodetes can be decreased by approximately 3% after 8 weeks of administering the method to the subject. The firmicutes:bacteriodetes ratio can be a contributing factor in obesity. Individuals with a high body mass index display gut microbiota differences at the phylum level and can have high firmicutes concentrations and can have low levels of bacteriodetes. It is noted, that changes in the microbiota have not been correlated to caloric content but rather to body mass index. Accordingly, altering this ratio can allow for weight loss in the individual if administered for a period of time.

In another example of the method for decreasing harmful gut bacteria, the harmful gut bacteria can include Actinobacteria. In one example, the reduction of the Actinobacteria after 8 weeks of daily administering the method to the subject can be at least about 5%.

EXAMPLES

EXAMPLE 1 -

BENCH TOP STUDY OF ANTHOCYANINS (AC) EFFECT ON TUMOR NECROSIS ALPHA- INDUCED Loss OF CACO-2 CELL BARRIER INTEGRITY The capacity of anthocyanins (AC) and seven AC -rich extracts containing different types of AC were measured to determine their ability to inhibit tumor necrosis alpha (TNFa) induced permeabilization of Caco-2 cell monolayers. The AC were also tested to determine the relationship between AC chemical structure/conformation and to determine the extent of the AC content to the extent of any protective capacity of the ACs to inhibit TNF-a induced permeability of Caco-2 cell monolayers. Materials

Caco-2 cells were obtained from the American Type Culture Collection (Rockville,

MA).

Cell culture media and reagents, were from Invitrogen/Life technologies (Grand Island, NY).

HBSS IX (21-022-CV) was obtained from Corning (Manassas, VA).

Millicell cell culture inserts 12 mm and 30 mm (0.4 μιη-pore polyester membranes) (PIHP01250 and PIHP03050, respectively) were obtained from EMD Millipore (Hayward, CA).

Fluorescein isothiocyanate (FITC)-dextran (46944- 100MG-F) and tumor necrosis factor- a human (TNFa) (T6674-10UG) were obtained from Sigma Chem. Co. (St. Louis, MO).

Human interferon gamma (IFN-γ) (#890 I SC) was obtained from Cell Signaling

Technology (Danvers, MA).

The pure anthocyanins: delphinidin 3-O-glucoside (myrtillin) (0938), cyanidin 3-0- glucoside (kuromanin) chloride (0915S), and malvidin-3-O-glucoside (oenin) (091 I S), were obtained from Extrasynthese (Genay Cedex, France).

The anthocyanin rich powdered extracts were provided by Pharmanex Research (Nu Skin Enterprises) and included: black chokeberry extract powder (35% total AC), black rice extract (20% total AC), wild blueberry extract (5% total AC), bilberry extract (36% total AC), crowberry extract powder (30% total AC), blueberry extract (25% total AC), and red grape extract (minimum 10% total AC).

Methods

The resolution of chemical structures was performed by molecular mechanics (MM2) according to Allinger using the routines available in ChemBio3D Ultra 11.0.1 (Cambridge Scientific Computing, Inc.). The structure of the anthocyanins appear in FIGS. -5-9.

Caco-2 cells were cultured in a phenol red free minimum essential medium (MEM) at 37°C and in a 5% (v/vl) C0 ₂ atmosphere. The MEM media was supplemented with: 10% (v/v) fetal bovine serum; antibiotics (50 μg/ml penicillin, and 50 μg/ml streptomycin); 1% of nonessential amino acid (NEAA); and 1% of sodium pyruvate. The cells were cultured for 21 days after confluence to allow for differentiation into intestinal epithelial cells. Over the course of the 21 days, the media was replaced every 3 days.

After 21 days, the caco-2 cells were differentiated into polarized monolayers in Millicell cell inserts (30 mm, 0.4 μπι-pore polyester membranes) and were placed in 6-well plates. The apical chamber consisted of 1.5 ml of media. After an initial addition to the apical chamber of 15 μΐ of a 1 mg/ml extract solution dissolved in 20% (v/v) ethanol, cells were incubated at 37°C and 5% (v/vl) C0 _2.

Sampling occurred at time zero, 1 hour, and 3 hours. For the initial time-point, 15 μΐ of medium was withdrawn from the apical chamber and the equivalent volume of extract was added. The plate was gently agitated and a 200 μΐ sample was immediately withdrawn from the upper chamber. At 1 hour and 3 hours both the apical and basolateral chambers were sampled. All samples were immediately acidified with 2.5 μΐ. of 12M HC1 and placed in a ^" 80°C freezer until time of analysis.

Polyphenolic metabolites present after interacting with the cell layer were identified in each extract by high performance liquid chromatography (HPLC)-mass spectrometry (MS)/MS. The liquid chromatography was performed on an Agilent series 1200 instrument (Agilent Technologies, Santa Clara, CA) coupled with a diode-array detector (DAD) that monitored the cells at wavelengths 280 and 520 nm. A Phenomenex Kinetex F5 pentafluorophenyl HPLC column (2.6 μΜ, 100 4.6 mm) with SecurityGuard® cartridges (PFP, 4.0 2.0 mm) were used for the separation with a flow rate of 0.70 mL min-1 and temperature of 37°C. Injector temperature was set to 4°C with a 7 μΐ. injection. A binary gradient was employed consisting of 1.0% formic acid (v/v) in water (mobile phase A) and 1.0% formic acid (v/v) in acetonitrile (mobile phase B) (Fisher Scientific, Fair Lawn, NJ). The gradient was as follows: 1% B at 0 minutes, 7.5% B at 7 min, 7.6% B at 14 min, 10% B at 17 min, 12% B at 18.5 min, 30% B at 24 min, 90% B at 25 min, 1% B at 26 to 30 min. Mass spectral data was acquired using an Agilent 6430 triple-quadrupole mass spectrometer with electrospray injection (Agilent Technologies, Santa Clara, CA, USA) and multiple reaction monitoring (MRM) selected as the mode of acquisition. Optimal MS/MS source parameters were set as follows, nebulizer at 40 psi, capillary voltage +4000 V (or -3500 V), gas temperature 325°C and flow of 5 L-min. Sheath gas was 250°C and sheath flow of 11 L-min.

Anthocyanin reference standards consisted of malvidin-3-O-glucoside, cyanidine-3-O- glucoside, cyanidine-3-O-galactoside, delphinidin-3-O-glucoside, pelargonidin-3-O-glucoside, and peonidin-3-O-glucoside (Extrasynthese, Genay Cedex, France). Anthocyanins that were detected, but did not have a reference standard quantified by equivalents of malvidin 3-0- glucoside. Phenolic acid reference standards included syringic, vanillic, protocatechuic, 4- hydroxybenzoic, gallic (Sigma-Aldrich St. Louis, MO) and 3-O-methylgallic (Extrasynthese, Genay Cedex, France) acids. Phloroglucinol aldehyde was supplied by Sigma-Aldrich (St.

Louis, MO).

To measure transepithelial electrical resistance (TEER) cells were differentiated into polarized monolayers by culture in transwell inserts (12 mm, 0.4 μιη-pore polyester membranes) placed in 12-well plates. Epithelial cell monolayers, were initially incubated for 24 hours with interpheron-γ to upregulate the T F-a receptor. Then the monolayers in the upper chamber were pre-incubated for 30 min with anthocyanin rich extracts (1-10 μg/ml) or purified compounds, or with myrtillin chloride, kuromanin chloride, and oenin chloride at 0.25, 0.5, and 1 μΜ

concentration added to the apical compartment. T Fa (5 ng/ml) was subsequently added to the basolateral compartment and cells incubated for 6 more hours.

To determine TEER assessment, the incubation media was removed from the apical and basolateral compartments, cells were rinsed with FIBSS IX and the same solution was added to both compartments and TEER was measured. TEER was measured using a Millicell-ERS Resistance System (Millipore, Bedford, MA) that includes a dual electrode volt-ohm-meter, see FIG. 10. TEER was calculated as:

TEER = (R _m - Ri) x A.

(I) wherein, R _m , transmembrane resistance; Ri, intrinsic resistance of a cell-free media; and A, the surface area of the membrane in cm ²

To determine paracellular transport, apical -to-basolateral clearance of FITC-dextran (4 kDa) was measured. After 6 hours of incubation with TNFa, the media was replaced in both compartments with fresh serum and phenol red-free MEM; FITC-dextran was then added to the apical compartment (100 μΜ final concentration) and allowed to incubate for 3.5 hours.

Subsequently, 100 μΐ of the medium in the basolateral compartment was collected and diluted with 100 μΐ of HBSS IX. The fluorescence was measured at exc: 485 nm and em: 530 nm in a fluorescence plate reader. Data was analyzed by one-way analysis of variance (ANOVA) using Statview 5.0 (SAS Institute Inc., Cary, NC). Fisher least significance difference test was used to examine differences between group means. A P value < 0.05 was considered statistically significant. Data is shown as mean ± SEM. The AC concentration in the various extracts as assessed by HPLC-MS/MS is shown

Table 5: Anthocyanin Content

Among the different extracts, total AC content varied between 8.5 and 82 pmol/g per extract. For the individual ACs, the content ranged between 0 to 30.05; 0 to 37.43; 0 to 9.70; 0 to 3.45; and 0 to 34.56 pmol/g per extract for the different glycosides of cyanidin, delphinidin, petunidin, peonidin and malvidin, respectively.

The chemical structure and conformation of the non-glycosylated forms (anthocyanidins) of the AC found in the studied extracts are shown in FIGS. 5-9. While rings A and C are identical for all the cyanidins, the positioning of the B ring with respect to the C ring showed diedric angle values of 39, 37, 34, 39, and 43 degrees for cyanidin, delphinidin, petunidin, peonidin, and malvidin respectively. The position of the B ring may play a role in the beneficial properties of cyanidins and delphinidins. As can be seen in FIGS. 7-9 petunidin, peonidin, and malvidin do not incorporate the same positioning of the B ring.

The crowberry extract contained the highest total AC content, 82 mol/g, and delivered one of the larger diversities of individual ACs (cyanidin, delphinidin, petunidin, peonidin and malvidin glycosides)(only bilberry AC were more diverse). Accordingly, the crowberry extract was selected to determine the concentration-dependent capacity of the AC-rich extracts to prevent TNFa-induced permeabilization of Caco-2 monolayers was assessed measuring both TEER and FITC-dextran paracellular transport. Caco-2 monolayers were incubated in the presence of 5 ng/ml TNFa in the lower chamber (basolateral side of the Caco-2 monolayer). This caused, a significant decrease (28%, p<0.05) in TEER and an increase in FITC-dextran paracellular transport (220%, p<0.05). These findings indicate that, under the current experimental conditions, TNFa caused an increase in permeabilization of the Caco-2 cell monolayer. The addition of the crowberry extract (1-10 μg/ml) to the upper chamber (apical side of the Caco-2 monolayer) caused a concentration-dependent recovery of the monolayer TEER and inhibition of TNFa-induced FITC-dextran transport to the lower chamber. As can be seen in FIGS. 11 and 12, TEER values increased as the amount of the extract increased and paracellular transport values decreased as the amount of extract increased. This indicated a dose dependent effect. Then the relative capacity of all of the AC-rich extracts to inhibit TNFa-induced Caco-2 cell monolayer permeabilization was determined. At 5 μg/ml concentrations, the extracts had differential effects inhibiting TNFa-induced alterations on TEER and FITC-dextran paracellular transport. See FIG. 13 and 14.

Table 6: Extract Indicators

The black chokeberry (1), black kernel rice (2) and blueberry (6) extracts were most effective at inhibiting TNFa-induced alterations on TEER, whereas, the black kernel rice (2), bilberry (4) and crowberry (5) extracts were most effective at inhibiting TNFa-induced alterations on FITC- dextran paracellular transport. The protective actions of the extracts on TNFa-induced monolayer permeabilization was concentration-dependent.

In order to evaluate if the AC present in the extracts could be involved in the beneficial effects of the extracts on Caco-2 cell barrier integrity the correlation between TEER and the total and individual extract AC content was assessed. TEER values were not significantly correlated with the total AC content, or with the content of peonidin, malvidin, and petunidin glycosides in the extracts; however, TEER values were significantly (p<0.03) correlated with the extracts' content of cyanidin (r: 0.73) and delphinidin (r: 0.81) glycosides, see FIGS. 15 and 16, suggesting a protective effect of these specific AC.

Table 7: Correlation between anthocyanin content and protective capacity to prevent TNFa induced TEER decreases

*p<0.05, only cyanidin and delphinidin concentrations were significantly positively

correlated with protective capacity against TNFa induced permeability, in other words, only cyanidins and delphinidins, not total ACs or other individual ACs were protective.

Table 8: Epicatechin, Catechin, and Total Catechin Content of the Extracts

It was discovered that epicatechin and catechins prevents TNFa induced losses of intestinal barrier integrity. See FIGS. 17-20. EXAMPLE 2 - TOXICITY STUDY

A toxicity study was conducted to determine the toxicity of a composition comprising cyanidins, delphinidins and a prebiotic blend after 90 days of oral administration to Wistar rats. The study also evaluated the dose response relationship and the determination of the no- observed adverse effect level.

Materials-Environment

Healthy Wistar rats {Rattus norvegicus) were selected at random to participate in the study. Then 60 female and 60 male rates between 6-8 weeks old, were allocated to 6 different groups.

Animals were individually housed in standard sized (40.5 x 24 x 18.5 cm)

polycarbonate cages with a sterilized corn cob bedding. The bedding was changed weekly and more often as necessary to keep the animals clean and dry.

The room temperature was maintained between 22 ± 3°C with a relative humidity between 30-70%. Artificial light was cycled for 12 hours of light and 12 hours of night. Air was changed a minimum of 12 times during each hour in the animal room.

Animals were offered a pelleted rodent diet and filtered water ad libitum. The water was placed in polycarbonate bottles with stainless steel sipper tubes.

Methods

The selected rats were examined by a veterinarian and then were acclimated to the test conditions for 5 days prior to the initial dosing. The rats were allocated into six different groups prior to initiation of the study using computer generated randomization tables. The weight variation of the animals was minimal and did not exceed ± 20% of the mean weight.

Table 9: Mice and Diet Groupings

Oral formulations were prepared daily, on the day of dosing. The formulation was dissolved in an aqueous solution. The high dose was anticipated to be equivalent to a human dose.

The formulation consisted of blueberry extract (3.6%), black currant extract (5.2%), black rice extract (15.6%), chicory inulin (48%), and short chain fructooligosaccharides (27.6%)) and was administered orally once per day, at the same time each day, for 90 consecutive days. The quantity of the formulation administered was 10 ml/kg of body weight.

All animals were observed daily for clinical signs and symptoms. Animals were observed individually in their home cage, during removal/hand held observations, in an open field, and for sensory reactivity. In the home cage, animals were observed for posture, breathing rate and extent, clonic involuntary movement, tonic involuntary movement, vocalisation, and palperbral closure. During hand held observations animals were observed for palperbral closure, lacrimation, eye and skin examination, piloerection, and salivation. During field observation animals were observed for gait, mobility, arousal, respiration, clonic movement, tonic movement, vocalisation, rearing, urine pools, fecal boluses, stereotype, and bizarre behavior. During sensory reactivity observations, animals were assessed for sensory reactivity including click response, touch response, tail pinch response, and approach response.

The animals were weighed on day 1, weekly during the course of the study, and on the day necropsy.

Urine was collected and analyzed for physical parameters and microscopic

examinations on the last week of treatment. In order to collect the urine, animals were housed for 16-18 hours in metabolic cages with graduated tubes attached to the bottom of the cages. On day 91, blood samples were collected for hematology and chemical analysis before necropsy and animals were fasted overnight for 16-18 hours prior to the blood collection. On day 91, animals in groups 1-4 were necropsied by an overdose of C0 ₂ and physically examined. The cranial, thoracic, and visceral cavities were opened and examined macroscopically. The organs were trimmed of tissues and fat and weighed. Organs and tissues were then collected and preserved in 10% buffered formalin except for the testes that were fixed in Modified Davidson's fluid. On day 105, animals in groups 5-6 were necropsied, physically examined, and their organs weighed. Results

During the study, the physical observations were mostly normal and/or consistent across all of the groups and determined to be toxicology insignificant. No clonic or tonic behaviors were observed. The only bizarre behavior was paper bitting. The paper bitting was observed everyday in all of the groups, including the control groups. The touch response and approach response were fast. The tail pinch was observed as a flinch and the pupil response was normal.

Hematology and clinical chemistry of the treated groups and the control groups did not show any significant differences. Urine chemistry also did not show any significant difference among all the experimental animals and comparable to animals of the Gl and G4 groups.

Mean body weights were similar among the groups in the study. The mean body weights gradually increased over the study. No changes in food consumption were observed. Insignificant changes in organ weight ratio were recorded and considered to be

toxicologically insignificant. Histopathological lesions were found in both sexes and in the control groups with random distribution. Accordingly, the lesions were considered to be random in nature.

The study concluded that the formulation did not produce any significant toxological changes in physical, physiological, neurobehavioral, biochemical, hematological, and histopathological parameters in any of the doses administered in the study. None of the treatment related changes were considered to be of toxicological significance. EXAMPLE 3 - ANIMAL STUDY 1

A mouse model of high fat diet induced obesity was used to investigate the potential capacity of a diet rich in anthocyanins to prevent and/or mitigate obesity induced intestinal inflammation, increased intestinal barrier permeability, and insulin resistance. The effects of anthocyanin supplementation on high fat diet induced alterations in (a) intestinal

inflammation, (b) intestinal permeability, (c) gut microbiota, and (d) anthocyanin metabolism were evaluated.

Materials

Sixty healthy male C57BL/6J mice (20-23 g) were obtained from Jackson

laboratories, and housed (4 mice/cage) in standard stainless steel cages. An enrichment environment was provided with the use of mouse houses and bedding. Mice were acclimated for one week before starting the treatments. Mice were grouped and (10 mice/group/time point) fed one of: the control diet; the control diet plus anthocyanins; a high fat diet; a high fat diet plus 2% anthocyanins; a high fat diet plus 20% anthocyanins; or a high fat diet plus 40% anthocyanins. The components in these diets are described below.

The control diet, TD.06416, was obtained from Harlen Teklad, WI. adjusted to approximately 10 % calories from fat.

The high fat diet, TD.06414, was obtained from Harlan Teklad, WI. and was a 60% fat diet. This diet was known to induce weight gain and the development of obesity over time. In parallel with weight gain, this diet was known to generate increases in lipid levels

(triglycerides, cholesterol, and adipocyte accumulation); increases in blood glucose, the development of insulin insensitivity; and when fed for extended periods of time, diabetes.

The anthocyanin mix was obtained from Nu Skin Enterprises. The mix was comprised of black rice extract, black current extract, and blueberry extract.

Methods

Mice were housed in stainless steel cages. Four mice were housed in each cage. 10 mice were placed in each group. Table 10: Diet and Dosing Data

Each group of mice were fed one of the specialized diets above. Food intake was monitored weekly. Body weight was gathered every two weeks and a fresh diet prepared. Feces were gathered and tested on weeks 0, 2, 4, 6, 8, 10, and 12. Urine was gathered on weeks 4 and 10. Gavage was collected on weeks 8 and 13. Blood was collected on week 10 and midway between weeks 12 and 13. On week 14, the mice were euthanized.

In order to measure intestinal permeabilization, paracellular transport of FITC dextrin was given by gavage at 8 weeks on the diets.

Gene arrays were conducted in different sections of the gastrointestinal tract.

Integrity of the tight junctions were measured as an expression of tight junction proteins and the evaluation of regulatory mechanisms.

Inflammation was determined by measuring F480+ macrophage infiltration in the intestinal mucosa, CRP in plasma, T F, MCP-1, and iNOS expression in liver/intestinal mucosa.

In addition, ITT/GTTs were performed at weeks 10 and 1 1 to determine the relationship between insulin sensitivity, intestinal health, and the microbiota.

Results

During the course of the diet, each group of mice had steady weight gain. The largest amount of weight gain was observed between weeks 0-8 with smaller increases between weeks 8-12. Overall mice on the high fat diet and the high fat diet + 2% AC gained the most weight over the study. Table 12: Average Weight Gain

The mice fed diets supplemented with 60% of the calories from fat sources, developed obesity, insulin resistance, and intestinal permeabilization within 8-16 weeks of the diet.

Despite the weight gain, the amount of food consumed by mice on the high fat diet was less than the amount of food consumed by mice on the control diets. The amount of food ate by each of the groups ranged between 2-5 grams each week during the study. Animals on the control and the control + anthocyanin diet typically consumed between 3 ¼ to 4 ½ grams of food per week. Animals on the high fat diet and high fat + diets typically consumed between 2 ¼ to 3 ¼ grams of food per week. Energy intake was similar among the groups. This study solidified the link between diet and overall weight; however, the study also showed that anthocyanin supplementation generally had a lowering trend on overall weight gain.

In addition, the overall colon length and weight of the mice was determined FIGS. 21, 22, and 23. FTC-dextran permeability, intestinal permeability, and endotoxemia were also measured. FIGS. 24, 25, and 26, respectively. Mice with the high fat diet had the most paracellular transport indicating higher intestinal permeability. Supplementing the high fat diet with even small amounts of anthocyanins, decreased or maintained lower levels of intestinal permeability. Mice with a high fat diet also experienced higher amounts of endotoxemia.

Blood was tested for glucose and insulin concentrations as shown in FIGS. 27 and 28. Table 13: Plasma Glucose and Insulin Concentrations

Mice on the high fat diet and on the diet comprising 20% AC exhibited the highest glucose and insulin levels. In addition, as the endotoxins increased so did the glucose tolerance and fasting insulin levels. FIGS. 29 and 30. Endotoxin levels also increased as IL-6 and IL-la levels increased; however, lL-β levels did not show a trend that correlated to endotoxin levels. FIGS. 31-33.

HOMA-IR (homeostasis model assessment of insulin resistance, this is a biomarker of insulin sensitivity), adiponectin, and leptin levels are also shown in FIGS. 34, 35, and 36 respectively. Adiponectin is an adipocyte-derived cytokine with anti -atherogenic, antiinflammatory, and anti-diabetic properties, which is decreased in obesity. Leptin is another adipocyte-derived cytokine that plays a role in the control of satiety and energy expenditure. Leptin insensitivity, like insulin insensitivity has been associated with weight gain and obesity. Ghrelin is a hormone known to stimulate appetite.

In addition triglyceride and cholesterol levels were measured in the plasma, liver, and the feces. See FIGS. 37-40. As predicted, the high fat diet led to increased plasma

triglycerides, however, this increase was prevented by all three AC doses. FIG. 37

It is well established that a high fat diet leads to hepatic steatosis (fatty liver) in this mouse, therefore, liver triglyceride levels and cholesterol levels were also measured. While triglycerides were significantly increased in the high fat diet control group, the 40% AC diet prevented lipid accumulation in the liver as triglyceride levels in the liver were similar in the control group, control+AC and HF+40% AC groups. FIG. 38. Cholesterol levels were also lower in all of the anthocyanin containing diets than the high fat diet. FIGS. 39 and 40. Liver triglyceride levels were also lower in the anthocyanin containing diets than the high fat diet. FIG. 41. Representative images of mice livers on each diet and their feces can be seen in FIGS. 42 and 43.

Interestingly, the highest triglyceride levels in the feces were found in mice consuming the high fat plus 40% AC diet, suggesting that the anthocyanins inhibited fat absorption, one likely mechanism by which the AC blend may have prevented the high fat diet induced hepatic steatosis and insulin insensitivity. Plasma cholesterol levels were elevated in mice consuming the high fat diet and the high fat + 2% and 20%AC groups, only the 40% AC diet attenuated plasma cholesterol levels. This may indicate that a supplement having anthocyanin content can lower plasma total cholesterol levels. All of the high fat diet groups exhibited increased cholesterol levels in the feces, a parameter which did not appear to be influenced by the addition of ACs to the diet.

EXAMPLE 4 - HUMAN STUDY

This study was conducted to determine the effects of a composition containing anthocyanins, inulin, and prebiotic fibers on the microbial composition of obese adults.

Materials

A single dose of the composition, in Table 14 below, contained 1.9 g inulin, 1.1 g fructooligosaccharides, 144 mg blueberry, 206 mg black currant extract, and 618 mg black rice extract.

Table 14: Composition

Methods

An initial screening was conducted two weeks prior to the start of the study. During the initial screening potential participants completed a review of their medical history, indicating all concomitant therapies, and identifying any inclusion and exclusion criteria. Potential participants were also measured for resting blood pressure, heart rate, weight, height, and body mass index. A pregnancy test was performed when applicable.

Fifty-one participants were enrolled in the study after completing the 2-week trial period. The participants were predominately female (73%) and Caucasian (93%). The accepted participants were males and females between 20-60 years of age. They had a BMI ranging from 29.9 to 39.9 ± 1 kg/m ² (29.2 to 40.6 kg/m ² ). Participants agreed to: maintain their level of physical activity throughout the trial period; discontinue the use of pre-biotic and pro-biotics and/or polyphenol supplements; and discontinue eating foods containing anthocyanins (blueberries, blackberries, cherries, grapes, grape juice, pomegranate, raspberries, huckleberries, strawberries, and wine) for two prior to the baseline assessment and during the study.

Participants were instructed to consume one sachet of the formulation every morning with breakfast, by mixing it into their beverage or food of choice. If participants forgot a dose they were instructed to consume the next dose as soon as they remembered. Participants did not consume more than one sachet per day. Participants also recorded diaries for concomitant therapies, adverse events, food records, daily bowel habits, and daily abdominal discomfort. In addition, participants completed bloating and flatulence questioners and had

anthropometric measures assessed.

The participants met with the investigational team at the initial assessment and on days 0, 29, and 57 of the study. On day 0 and 57 stool samples, urine samples, and blood samples were collected.

Stool samples were collected within 48 hours of day 0 and day 57. The microbial composition and calprotectin were measured in stool samples by a lab at U of Wisconsin. Microbial composition was measured by 16s rRNA on the illumina platform and R&D Systems (Minneapolis Mn.).

Laboratory parameters (CBC, electrolytes (N, K, CI, Ca), HbAlc, creatine, AST, ALT, GGT, and bilirubin) were assessed at the initial assessment and at the end of the study.

Urine screenings were administered at the KGK Synergize clinic. Blood parameters were measured by LifeLabs central laboratory by a standard method.

Data entry and verification was executed according to KGK Synergize's Standard Operating Procedures. Statistical analysis was conducted on the results of all participants that consumed at least 80% of the treatment doses. Variables were tested for normality and log- normality. Non-normal variables were analyzed by appropriate non-parametric tests.

Numerical efficacy and endpoints were formally tested for significance by paired student t- tests.

Results

Forty-six of the 51 participants originally enrolled in the study completed the study. Four of the participants dropped out after the day 0 visit and before the first comparison measurement on day 29. One individual dropped out between the visits on day 29 and day 57.

Microbial Diversity

Participants supplementing with the composition experienced a favorable change in their microbial composition as demonstrated by a change in their Firmicutes:Bacteriodetes ratio. FIG. 44. The ratio decreased from 4.98 to 1.45 {Firmicutes decreased 74.9% to 59%; Bacteriodetes increased 13.8% to 34.5%). In addition, Actinobacteria decreased from 8.5% to 3.4%). A total of 8 phyla (6 bacteria, 1 archaea, and 1 other) and 40 genera (7 Actinobacteria, 8 Bacteroidetes, 1 Eurychaeota, 21 Firmicutes, and 3 Proteobacteria) were changed following the supplementation.

Inflammation

Following the study fecal calprotectin levels were reduced indicating a trend for a reduction in gastrointestinal inflammation. Calprotectin levels are tabulated below and graphically presented in FIG. 45.

Bowel habits

A 5% increase was found on weeks 6 and 7 in the Bristol stool score when compared to baseline. The number of bowel movements did not change over the study; however, the bowel habits were improved. FIG. 46. Participants reported a reduction in straining before (33%) and while stopping defecation (51-54%) and a reduction in incomplete bowel movements.

Conclusion

Overall the study indicated that the formulation was capable of improving the intestinal microbiome in mildly to moderately obese yet otherwise healthy individuals. Over the study, participants experienced a significant reduction in the Firmicutes and a significant increase in Bacteroidetes proportions. The Firmicutes:Bacteroidetes ratio decreased from day 0 to day 57 with supplementation. The ratio changed from 4.98 to 1.45. In addition,

Actinobacteria levels decreased. These three phyla make up about 97% of the bacterial composition at baseline (97.2%) and following supplementation (96.9%).

Thirty adverse events were recorded by 18 participants in the study. Of the thirty reported incidents, eleven were assessed as unlikely and 7 were assessed as unrelated. Two of the adverse events were determined to be likely and included feces discoloration and tooth discoloration. The ten possible adverse events included reports of abdominal discomfort, diarrhea, feces discoloration, frequent bowel movements, and vomiting.
