An experimental model for studies of zinc bioavailability from milk and infant formulas using extrinsic labeling.

The ability to assess zinc bioavailability from various diets is essential as the zinc content on many foods can be low or marginal. We have investigated the absorption of zinc from human milk, cows' milk, cows' milk formula (whey-adjusted) and soy protein formula as these fluids can comprise the majority of an infant's diet. Radiozinc was added to the diets in tracer amounts. The extrinsic 65Zn was shown by ultracentrifugation, ultrafiltration, and gel filtration to add to milk fractions and individual binding compounds in a manner analogous to the distribution of native zinc, validating the use of extrinsically labeled milk diets. Labeled diets were fed by intubation to 16-day-old suckling rats. Animals were killed after 4 h and tissues removed and counted. Zinc bioavailability was 28% from human milk, 24% from whey-adjusted cows' milk formula, 15% from cows' milk, and 10% from soy formula. Intubation studies using adult rats showed that zinc absorption was lower from all the diets; however, it was still highest from human milk and cows' milk formula. These results show that the rat pup model may provide a rapid, inexpensive, and sensitive method to assay bioavailability of zinc from infant foods.

Iron nutrition and growth of breast- and formula-fed infants during the first 9 months of life.

Feeding of iron (Fe)-fortified (12-15 mg/L) infant formulas is an effective and convenient means to protect infants from Fe deficiency. To study lower levels of Fe fortification of infant formulas (3 or 6 mg/L) compared with those currently in use, we compared Fe intake and Fe nutritional status of three groups of healthy, term infants between 90 and 274 days of age. One group received an Fe-fortified whey-predominant formula (3 mg/L) and the second group received the same formula with a higher Fe level (6 mg/L). A comparison group was breast-fed at least until 274 days of age. All infants received infant foods and cereals according to European Community recommendations. Mean Fe intake of infants fed formula fortified with 3 mg/L was significantly lower at 183 and 274 days of age (p < 0.05) than that of infants fed formula fortified with 6 mg/L. None of the infants fed the formula fortified with 3 mg/L met the recommended daily allowance value (10 mg) for infants between 6 and 12 months of age. Hemoglobin, hematocrit, mean corpuscular volume, free erythrocyte protoporphyrin, and serum ferritin levels were similar in the formula-fed groups; none of the infants had depleted Fe stores (ferritin < 10 micrograms/L) at 183 and 274 days of age. Thirteen percent of breast-fed infants had depleted Fe stores at 183 days of age, but only 3% were depleted at 273 days of age, when Fe-fortified beikost was already part of the diet. No influence of Fe nutritional status was found on zinc and copper nutritional status or on growth.(ABSTRACT TRUNCATED AT 250 WORDS)

[Infant formulas and soy protein-based formulas: current data].

For many years soy bean-based formulas (SBBF) were the only dietary product used for infants with cow's milk intolerance. At the present time, their place in infant nutrition is reduced as a result of the availability of new dietary products without lactose and/or cow's milk proteins and the recognition of soy bean protein allergy. There is no evidence that SBBF have any efficiency in infant colic. SBBF have no indication in the prevention of allergy, nor in premature infants' nutrition. Their main indication is the feeding of infants of vegetarian parents who do not want to use cow's milk products. Studies have shown that SBBF contain large quantities of phytoestrogens, particularly isoflavone. Because of experimental data suggesting a possible deleterious effect of phytoestrogens on the neuroendocrine maturation, the reduction of their content in SBBF must be considered.

Strategies for the prevention of iron deficiency: iron in infant formulas and baby foods.

Iron deficiency is the most prevalent nutrition deficiency among infants and young children in industrialized as well as developing countries. It is a condition that is preventable through appropriate dietary measures. The infant born at term is endowed with a sizable amount of iron, which allows the infant to be fed a nearly iron-free diet (e.g., breast milk) for 4-6 months without becoming overtly iron deficient. This has led some to conclude that depletion of iron stores in healthy infants is a normal and, hence, innocuous process that usually gives way to gradual repletion of iron stores as dietary diversification leads to greater iron intakes. Preservation of maternal iron stores at the expense of infant iron stores may have offered survival advantages to the human species during evolution. But there is no evidence that depletion of iron stores can offer advantages to infants in industrialized or developing countries. On the contrary, there is ample documentation of shortterm as well as long-term adverse effects from iron deficiency. Prudence therefore dictates that a high priority be assigned to the prevention of iron depletion and deficiency among infants and young children worldwide.

Reproducing the bifidogenic effect of human milk in formula-fed infants: why and how?

Awareness of the key role of the intestinal microflora in the generation of the immunophysiological regulation and in the defence against pathogenic agents has attracted our interest in ways of manipulating the microbiota to improve health. Dietary modulation of the intestinal microflora is today one of the main topics of interest in the nutritional sciences. Performing this modulation in the neonatal or early infancy period, when immunological programming takes place, is a relatively new concept. Fructo-oligosaccharides (FOS) and galacto-oligosaccharides (GOS) are prebiotics whose bifidogenic activity has been proven in adults. However, only recently have they been combined in infant formulas to reproduce the prebiotic effect of human milk oligosaccharides. In two consecutive trials, it has been demonstrated that supplementation of infant formulas with a mixture of GOS and FOS modified the fecal flora of term and preterm infants, stimulating the growth of Bifidobacteria. In the trial with term infants, the bifidogenic effect of the prebiotic mixture was dose dependent and there was also a significant increase in the number of Lactobacilli in the supplemented group. These findings offer a promising horizon for the early prevention of allergy and infections in infants.
