Future outlook for food function research.

The results of research on food functionality in Japan have been passed on to society in the form of Foods for Specified Health Uses and Foods with Functional Claims. However, it is also true that there are people who do not experience any health benefits even when they consume these foods. To clarify the factors that cause such individual differences in the health benefits of food, research into the following points is important: 1) Elucidation of the molecular mechanisms behind why food factors exert their functionality. 2) Research into the functional interactions between food factors that exert their functionality in multi-component systems. 3) Research into the functionality of food factors that have not been the subject of research until now. We will introduce the results of our research in these areas. We will also discuss our expectations for the application of food functionality research to pharmaceutical development as an extension of this research.
