This talk explores how the modernization of global diets has reduced food diversity and displaced fermented foods, contributing to rising rates of chronic disease. Drawing inspiration from traditional Japanese diets, the research focuses on fermented foods and their impact on gut health and immunity. The speaker highlights the discovery of bioactive, bioavailable cyclic dipeptides in certain Japanese fermented foods, which enhance immune cell function while reducing harmful inflammation. The work suggests that affordable, traditional fermented foods can play a powerful role in supporting immune health and preventing disease.

This research investigates brain circuits that regulate sodium appetite and salt preference. By manipulating sodium-sensitive neurons and immune signaling pathways in mice, the study demonstrates how sodium craving can be altered without changing food composition, opening new possibilities for treating excessive sodium consumption and sodium-related cardiovascular and metabolic disorders.

This research investigates how different low-calorie sweeteners interact with the body’s sweet-taste receptor and influence biochemical signaling. By measuring the molecular “messenger” responses triggered by various sweeteners, the project aims to identify which ones have healthier metabolic effects, supporting better choices for weight management, diabetes, and general well-being.
