An isoflavone aglycone-containing composition having genistein as a main aglycone is produced by a process comprising allowing a protease and &bgr;-glucosidase to act on a soy protein raw material, an extract of a soy protein raw material or a by-product of a soy protein raw material to water-solubilize the protein of soybean origin and to convert isoflavone glycosides to the corresponding aglycones, separating water-soluble components from the enzymatic reaction mixture, and recovering water-insoluble matter.

Process for producing isoflavone aglycone-containing composition

A proanthocyanidin and an isoflavone are incorporated into a food. Compounding of grape seed extract as a proanthocyanidin and soy sauce cake extract as an isoflavone gives an anti-arteriosclerotic composition that is effective at a small intake.

Anti-arteriosclerotic food

A health diet for preventing life-habit diseases (adult diseases) is provided. The health diet is prepared by directly encapsulating or tableting an organic solvent extract of soy sauce cakes or an aqueous alkali extract of a soy sauce oil, or blending the extracts with a diet.
