Abstract: The present invention provides a peptide and a composition which are suitable for oral ingestion, and which have a skin aging-inhibiting activity, a collagen-production promoting activity, an epidermal turnover promoting activity, and a cutaneous cell-proliferating effect. The present invention also provides a medicament and a functional food which have a skin aging-inhibiting activity, a collagen-production promoting activity, and a cutaneous cell-proliferation promoting activity. The present invention provides a composition including at least one peptide of Asn-lle-Pro-Pro-Leu, lle-Pro-Pro-Leu, lle-Pro-Pro, Pro-Val-Val-Val-Pro-Pro, Val-Pro-Pro-Phe, Val-Pro-Pro, Phe-Pro-Pro-Gln, and Leu-Pro-Pro-Thr.

Abstract: The present invention provides an orally ingestible composition and a method for regulating an autonomic nervous activity. In particular, the present invention provides an orally ingestible composition capable of suppressing an increase in a sympathetic nervous activity, and an orally ingestible composition capable of promoting a parasympathetic nervous activity. The present invention is a composition for regulating an autonomic nervous activity, comprising, as an active ingredient, Tyr-Pro or a salt thereof.

Abstract: The invention provides functional food and beverage that produce, through oral intake, a promotive effect on normal epidermal keratinization, and an epidermal differentiation and keratinization promoter for use in such functional food and beverage. The epidermal differentiation and keratinization promoter of the present invention contains, as an active component, fermented milk whey obtained by fermentation of milk with bacteria including lactic acid bacteria, such as Latobacillus helveticus. The functional food and beverage for promoting epidermal keratinization of the present invention contains the epidermal differentiation and keratinization promoter.
