The results are reported of a prospective, longitudinal, nutritional study of 391 infants, who were representative of the Adelaide population. The results include a description of the change in pattern of milk and solid food intake, the percentage contribution from carbohydrate, fat, and protein, and its relationship to the type of diet the child was having through infancy. The energy intake of these food classes is described, and the relationship to both the contribution from each nutrient group, and the type of milk formula used is described for each age studied.It is proposed that these studies on normal Australian children provide evidence of the inter-related nature of the qualitative and quantitative aspects of diet during infancy, and may form a basis for further studies on the relationships between nutrition and the growth of fatness, variation in blood pressure, and nutritional influence on lipoprotein metabolism.
