Abstract
The study was initiated to identify the effects of recent changes in dietary pattern in Japan on nutrient intake. In the large city of Osaka, Japan, 24-h food duplicate samples were collected from 26 middle-aged women, and nutrients in the duplicates were estimated in reference to standard tables of food composition. The subjects took 1844 kcal (7.72 MJ) energy, 67.5 g protein, and 54.5 g lipid (37% from plants) per day. Micro-nutrient intakes were generally sufficient, but NaCl intake tended to be excessive, and the relatively high body mass index (>25 in six cases) suggested a possibility of over-eating. The food composition was rich in rice and fish, being basically of a traditional type. Consumption of bread, an acquired habit, was observed in 65% of the breakfasts but less so in lunch and none in dinner. Thus, the acceptance of bread in place of rice was limited and did not induce substantial alteration in nutrient intakes.
