Are current dietary guidelines for young children a prescription for overfeeding?
New estimates for the energy requirements of young children have been derived by combining the energy deposited during growth with measurements of total energy expenditure obtained by use of the new doubly-labelled water (2H2(18)O) method in 355 healthy infants aged 0-3 years. The resultant values of 110, 95, 85, 83, 83, 84, and 85 kcal/kg/day at 1, 3, 6, 9, 12, 24, and 36 months, respectively, are substantially lower than current Department of Health and Social Security and FAO/WHO/UNU recommended dietary allowances. Evidence from diet surveys suggests that changes in infant feeding practices are largely responsible for the apparent reduction in energy requirements. Dietary guidelines may need to be reappraised, to avoid overfeeding of infants.
