  • Patent number: 8357776
    Abstract: The present invention provides a composition (composition for suppressing re-elevation of cholesterol) that has the effects of suppressing re-elevation of cholesterol in patients with high cholesterol or pre-high cholesterol, and that can therefore be used to suppress re-elevation of cholesterol in those patients. The present invention also provides a composition which, due to the effects described above, can be used to prevent or treat conditions or diseases caused by high cholesterol due to cholesterol re-elevation, specifically hypercholesterolemia, arteriosclerosis and diseases and conditions stemming therefrom. The composition of this invention uses as an active component an edible protein hydrolysate, preferably a globin proteolysate or a peptide consisting of Val-Val-Tyr-Pro.

  • Patent number: 5723443
    Abstract: The invention concerns a low molecular weight proteinaceous agent which can be used to reduce body fat content by suppressing fat digestion and absorption thus reducing body fat and limiting excess fat accumulation. The proteinaceous material is a mixture of low molecular weight peptides. This mixture has about at least 50-67% of peptides having an average chain length of 3-4 amino acids. This material is administered to subjects in amounts of at least 0.1 to 50 weight percent relative to the amount of fat consumed by the subject.
