To obtain a health food scarcely affected by gastric acid and water and effectively exhibiting the intestinal function controlling action by encapsulating a specific oil and fat and a specific valuable bacterium in a specific enteric seam capsule.

This health food is produced by encapsulating (A) an oil and fat having intestinal function controlling action, (B) a valuable bacterium having intestinal function controlling action and optionally (C) a water-absorbing substance (e.g. dried starch) in (D) an enteric seam capsule insoluble in gastric acid and soluble in the intestines. The component A is olive oil, palm oil, cottonseed oil, wheat embryo oil, fish oil, etc., the component B is Lactobacillus acidophilus, Lactobacillus casei, Bifidobacterium longum, etc., and the component D is e.g. a seam capsule made of gelatin and coated with a component suppressing the solubility in gastric acid (e.g. zein) or a seam capsule composed of gelatin containing sodium alginate.
