Food can be either medicine or poison depending on your physical condition. For example, dietary fiber rich foods are harmful while running since sympathetic nerves inhibit GI tract activities. Water is one of the essential nutrients but drinking too much water when you are losing a lot of salt by sweating can dehydrate you even more (since your kidneys sense the diluted blood sodium levels and begin to filter excess water to let you pee more). Simple sugars are not healthy foods but are excellent fuel during endurance sports. Let’s find the right combination and timing of foods suitable for your lifestyle.

Meet Kayo

I was born in Japan, where I received a BS in Nutritional Science and certification as a registered dietitian. I received a PhD in Nutritional Science and Genetics from the University of Arizona, worked at UC Irvine and UC San Diego. As a bio-researcher, I studied how nutrients and hormones affect human health at the molecular level, and the strong involvement of gut microbiome (genetic material in GI tract) on human health. My cooking style is based on Japanese and Mediterranean diets, which are rich in dietary fiber, fermented foods, healthy fats (including olive oil, nuts and seeds) but do not require condiments high in salt and sugar (such as BBQ sauce and ketchup). By using my training in science and culinary skills as a dietitian, I work as an independent nutrition/health/cooking specialist in US and Japan.
