摘要：The National Nutrition Survey in Japan has played an important role for nutrition policy in this country, by monitoring nutrition and health status of the Japanese since 1946. During those 50 years, diet of the Japanese has remarkably changed, with the proportion of fat intake in total energy being more than 25% and salt intake gradually decreased. The aim of this survey also has shifted from the policy making for food supplies to monitoring the over intake for prevention of diet-related chronic diseases and health promotion.
