Protein Nutrition during Infancy and Childhood

Author(s): I. Axelsson

During breast-feeding, protein intake is low in humans compared to that of many animals. The protein content in breast milk is about 1g/100 ml and the daily protein intake approximately 1g/kg/day. During the weaning period, the protein intake increases remarkably and even after the first year of life. There is a shift from about 1g/kg/day to 3-4 g/kg/day in spite of the fact that the protein requirements are decreasing. The long term consequences of this phenomenon are obscure. A high protein intake may have both endocrine, metabolic, and physiologic effects and may increase the risk of obesity.

Iron and Zinc Nutrition in Infancy and Childhood

Author(s): B. Lönnerdal

Iron deficiency and iron deficiency anemia continue to be a nutrition and health problem in infants and children, particularly in developing countries, despite considerable efforts to reduce its prevalence.It was not until the mid-1970s that zinc was found to be an essential nutrient for infants and children. Formula-fed infants were then found to have lower concentrations of zinc in hair and serum than breast-fed infants, and their growth was slower. By increasing the concentration of zinc in formula three-fold, hair and zinc concentrations became similar and their growth improved. The awareness of zinc deficiency as a global health problem is more recent.

Over the last two decades there has been an explosion of interest and a growing demonstration of the potential benefits of consumption of live microorganisms, generally referred to as “probiotics”, in particular for pediatric populations.
