Abstract
We developed a foods and dishes database from the data of 3-day weighed dietary records (DR) of 1,071 participants in the National Institute for Longevity Sciences, Longitudinal Study of Aging (NILS-LSA). This database (594 dishes or foods) contained the mean weight, number of servings (SV) for each category of the Japanese Food Guide Spinning Top, and the mean weights of the food and nutrient contents. We applied the food balance questionnaire (FBQ), which could count SV, and estimated the nutritional intake by using the database. FBQ and 1-day DR were produced from 91 volunteers in Aichi Prefecture (35-79 yr), the validity of the nutrient intake assessed by FBQ being checked by 1-day DR. The differences in nutrient intakes by FBQ and 1-day DR, and the differences between quintiles of FBQ and 1-day DR were examined.Mean SV values were 4.3 (grain dishes), 5.6 (vegetable dishes), and 6.1 (fish and meat dishes). Carbohydrate, salt, vitamin B1, and niacin were significantly different between FBQ and 1-day DR. The 65% (salt) to 84% (vitamin C) subjects were categorized in the same or adjacent category. Extreme differences between quintiles were in the 0-3% range. FBQ was proved useful to easily check the diet balance and nutritional intake.
