Abstract:
... Tea is a beverage commonly consumed worldwide. Matcha is a type of green tea produced by drying and grinding tea leaves (Camellia sinensis L.) into a fine powder. Matcha contains catechin, theanine, and caffeine, which affect cognitive function. Epidemiological studies conducted in Japan have shown that green tea consumption improves cognitive impairment. Previously, we found that daily matcha int ...

Participants (n = 369) of this study were recruited from all 47 prefectures in Japan. Sex-specific formulas were developed based on the ratio of urea nitrogen to creatinine concentration obtained from 3 spot urine samples. Validity of the formulas was examined against two 24-ho ...

This cross-sectional study was based on 1-day weighed dietary record data from 3866 children in the 2012 National Health and Nutrition Survey, Japan. The GI of foods was assigned based on a stepwise published st ...

Abstract:
... Seaweeds are considered a potential source of antiobesity agents. Because Caulerpa, a seaweed, has been consumed for food in Japan, China, South Korea, and Australia, we hypothesized that Caulerpa okamurae may have antiobesity effects in an animal model of high-fat diet (HFD)–induced obesity in C57BL/6 mice. Herein, we found that the ethanolic extract of C okamurae (COE) significantly inhibited li ...
