The mineral contents of commercially prepared box lunches (bentou) and daily dishes (souzai) were surveyed and compared with those of home-prepared meals in order to evaluate the nutritional values of commercially prepared meals. More than 50 commercially prepared box lunches (including sushi and university cafeteria meals) and 40 daily dishes were collected from the Kinki area. Calcium, phosphorus, iron, sodium, potassium, magnesium, zinc, and copper were each determined by the inductively coupled plasma (ICP) method. The commercially prepared box lunches contained lower amounts of minerals, except for sodium, than home-prepared meals. This result suggests that daily eating of commercially prepared box lunches cannot satisfy the required intake of calcium, iron, potassium, manganese, and zinc. In addition, the commercially prepared box lunches and daily dishes contained more sodium than the home-prepared equivalents. Attention therefore is needed to avoid calcium deficiency and sodium excess with commercially prepared box lunches and daily dishes.
