Breakfast habits by using questionnaires, were established in a total of 4717 South African pupils of 16 to 18 yr. In the groups of rural and urban Black, Indian, European-African-Malay, and white pupils studied, respective proportions who had no solid breakfast (both sexes combined) were approximately 21, 19, 13, 13, and 14%. Proportions who had only porridge or bread (or toast) plus drink were 77, 73, 61, 71, and 56%. Such breakfast provided ranges of means of 223 to 345 kcal, 9 to 14 g protein, 7 to 18 g fat, 51 to 185 mg calcium, and 3.2 to 5.1 mg iron. Proportions who had a cooked breakfast (including egg, meat, fish), eaten with or without a cereal food, were 1, 4, 17, 8, and 29%. Such meals contributed means of 495 to 704 kcal, 11 to 26 g protein, 24 to 39 g fat, 110 to 225 mg calcium, and 3.9 to 5.5 mg iron. In the South African groups studied, the issue of breakfast or no breakfast had no clear-cut bearing on weight, height, class position, or frequency of absence from school. The degree by which, in a given community, nutrition in general and breakfast in particular, regulates health and/or academic performance, needs proper research in prospective studies.
