Intervention Program

The 6 week intervention program was explained in our previous report⁴⁾. Briefly, a lecture and group work were conducted focusing on easy ways to consume the foods classified as constituting the Japan Diet (consumption of more fish, soybeans and soy products, vegetables, seaweed, mushrooms, konjak, and unrefined cereals while reducing animal fat, meat and poultry with fat, sweets including desserts and snacks, and alcoholic drink intakes). Each participant was required to keep a daily performance record in terms of the intakes of foods comprising the Japan Diet for 6 weeks. The subjects were instructed to maintain their habitual physical activity levels during the study period.
