Recent views on infant nutrition.

Abstract

Particular problems under discussion in the field of infant nutrition today are the following. (1) The frequency of breastfeeding including the effect of promotion to uncrease it. (2) The protein requirement of low birth weight infants including relevant parameters for evaluation of the requirement. Recent studies indicate that the protein requirement of low weight is only slightly higher (or may be the same) as that supplied by breast milk. (3) The tolerance for intake of certain nutrients in early infancy - mainly protein and minerals - in relation to the development of organ functions, including homeostatic disturbances that may arise when the tolerance is exceeded. Adverse effects of a too high protein intake are particularly acidosis and increased osmolar load on kidney function. Excess mineral adds to the renal solute load, implying a threat to water balance. (4) The introduction of Beikost, when and why, and (5) Atherosclerosis as a problem for the pediatrician. The need for identification of risk factors, especially screening for hyperilipidemia, in early life and for recommendation of dietary measures instituted in early childhood has to be further studied.
