Abstract. Vitamin B12 (B12) plays in an important role in the development and function of the brain and nervous system, and adequate B12 status is especially important for the normal development of infants. In previous research conducted in Guatemala City we reported a high prevalence of B12 deficiency in lactating women and their infants 3 and 12 months of age, and low B12 concentrations in breast milk. The objective of this study was to assess predictors of serum B12 concentration in predominantly breastfed Guatemalan infants including intake of B12 from breast milk and other foods. Serum B12, breast milk and other food intakes, anthropometry, morbidity and socioeconomic status were assessed in infants 6.7 ± 0.6 months of age (n = 127, 52% female) in peri-urban Guatemala City. Twenty-four percent of infants had deficient B12 status (serum B12 concentration < 148 pmol/L) and 37% had marginal B12 status (148–220 pmol/L). Serum B12 concentrations were negatively correlated with infants’ consumption of energy from breast milk (r = −0.37, p = 0.001), and positively correlated with their total consumption of animal source foods, especially cow’s milk (r = 0.40, p = 0.001). Based on previously analyzed breast milk B12 concentrations in a nearby community, breast milk provided < 10% of the recommended daily B12 intake for this age. We conclude that there was a high prevalence of B12 deficiency in these Guatemalan infants by 6 months of age. Serum B12 was higher in infants consuming more cow’s milk and lower in those consuming more breast milk.

Iron Deficient

The pediatrician is faced with a difficult challenge in providing recommendations for optimal nutrition in older infants. Because the milk (or formula) portion of the diet represents 35% to 100% of total daily calories and because WCM and breast milk or infant formula differ markedly in composition, the selection of a milk or formula has a great impact on nutrient intake. Infants fed WCM have low intakes of iron, linoleic acid, and vitamin E, and excessive intakes of sodium, potassium, and protein, illustrating the poor nutritional compatibility of solid foods and WCM. These nutrient intakes are not optimal and may result in altered nutritional status, with the most dramatic effect on iron status. Infants fed iron-fortified formula or breast milk for the first 12 months of life generally maintain normal iron status. No studies have concluded that the introduction of WCM into the diet at 6 months of age produces adequate iron status in later infancy; however, recent studies have demonstrated that iron status is significantly impaired when WCM is introduced into the diet of 6-month-old infants. Data from studies abroad of highly iron-deficient infant populations suggest that infants fed partially modified milk formulas with supplemental iron in a highly bioavailable form (ferrous sulfate) may maintain adequate iron status. However, these studies do not address the overall nutritional adequacy of the infant's diet. Such formulas have not been studied in the United States. Optimal nutrition of the infant involves selecting the appropriate milk source and eventually introducing infant solid foods. To achieve this goal, the American Academy of Pediatrics recommends that infants be fed breast milk for the first 6 to 12 months. The only acceptable alternative to breast milk is iron-fortified infant formula. Appropriate solid foods should be added between the ages of 4 and 6 months. Consumption of breast milk or iron-fortified formula, along with age-appropriate solid foods and juices, during the first 12 months of life allows for more balanced nutrition. The American Academy of Pediatrics recommends that whole cow's milk and low-iron formulas not be used during the first year of life.

Gastroduodenal Motility

It is known that breast milk empties more quickly from the stomach than does infant formula. We studied the difference in gastroduodenal motility between neonates fed with human milk and those fed with infant formula. Twenty-four five-to 36-day-old neonates were fed with mother's breast milk or with a cow's milk-based formula. Postprandlial gastroduodenal contractions were recorded manometrically for three hours. Repetitive, high-amplitude nonmigrating contractions were the dominant wave form during the postprandial period. The number of episodes, duration, amplitude, and frequency of nonmigrating contractions were not different following the different feedings. The migrating myoelectric complex, which signals a return to the interdigestive (fasting) state, appeared in 75% of breast milk-fed infants but only 17% of formula-fed infants (P &lt; .05) within the three-hour recording period. Because contractions were similar following the two meals, but a fasting state recurred more rapidly in breast-fed infants, we conclude that factors other than phasic, nonpropagated antroduodenal contractions were responsible for the differences in gastric emptying between breast milk and formula.

Β Lactoglobulin

Previous studies have suggested that an unidentified cow's milk protein, other than β-lactoglobulin and casein, might play a pathogenetic role in infant colic. Therefore, a radioimmunoassay was used to analyze human breast milk and infant formula samples for the presence of bovine IgG. Milk samples from 88 of the 97 mothers tested contained greater than 0.1 µg/mL of bovine IgG. In a study group of 59 mothers with infants in the colic-prone 2- to 17-week age group, the 29 mothers of colicky infants had higher levels of bovine IgG in their breast milk (median 0.42 µg/mL) than the 30 mothers of noncolicky infants (median 0.32 µg/mL) (P &lt; .02). The highest concentrations of bovine IgG observed in human milk were 8.5 and 8.2 µg/mL. Most cow's milk-based infant formulas contained 0.6 to 6.4 µg/mL of bovine IgG, a concentration comparable with levels found in many human milk samples. The results suggest that appreciable quantities of bovine IgG are commonly present in human milk, that significantly higher levels are present in milk from mothers of colicky infants, and that bovine IgG may possibly be involved in the pathogenesis of infant colic.

The case records of 11 infants with prolonged hyperbilirubinemia have been presented. The elevation of indirect reacting bilirubin in these infants may be due to interference with the normal conjugating mechanism by a substance present in breast milk. Introduction of cow's milk formulas should be carried out as part of any extensive investigation of prolonged hyperbilirubinemia of the indirect type in otherwise well infants who have been wholly breast fed from birth.

Abstract Galectin-3 stabilizes cell-cell junctions and regulates inflammatory pathways in the gut-liver axis. Galectin-3 knockout (Lgals3−/−) mice have atypical behaviors by obscure mechanisms. Given that BALB/c mice naturally develop low-sociability, stereotypies and restrict interest, they have been included as autism experimental model. Our major aims were to investigate whether galectin-3 in the gut-liver axis interferes with autistic-like behaviors analyzing BALB/c Lgals3−/− mice or under partial inhibition of galectin-3 oral intake of cow’s milk for 7 days. Behavioral patterns were assessed using a three-chambers test, open field, and self-grooming. Histological analysis and immunohistochemistry (Galectin-3, NOS-2, Iba-1, Ki-67, Dll-4, Shank-3, Synaptophysin and Drebrin) were performed in gut, liver, and/or brain. Lgals3−/− mice amplified stereotypies, social retraction and restrict interest associated with reduction of cerebral Shank-3+ cells. In Lgals3+/+ mice, cow’s milk intake also amplified atypical behaviors, reduced galectin-3 in enterocytes and Kupffer cells, and disturbed niches of intestinal KI67+ and Dll-4+ cells and hepatic NOS2+ cells. In the brain of milk-treated mice, Iba-1+ microglial cells and NOS2+ Purkinje cells were increased whereas Shank-3+ and Drebrin+Synaptophysin+ cells were reduced suggesting, for the first time, that galectin-3 interferes with autistic behavior. Perhaps, a perspective to new therapies in genetically predisposed individuals to atypical behaviors.

Milk Substitutes

Cow’s milk is an important part of the diet in infants and preschool children. Breast milk is the most appropriate food for young infants, but when it is not available, or on the rare occasions when it is inappropriate, a feed based on cow’s milk is usually used. Sometimes, however, an infant needs a nutritionally complete formula feed based on something other than cow’s milk. Older children may likewise need a substitute for cow’s milk. This article discusses when such substitutes are needed and the merits of the different preparations.

Maternal diet during pregnancy and lactation may affect the propensity of the child to develop an allergy. The aim was to assess and compare the dietary intake of pregnant and lactating women, validate it with biomarkers, and to relate these data to physician-diagnosed allergy in the offspring at 12 months of age. Maternal diet during pregnancy and lactation was assessed by repeated semi-quantitative food frequency questionnaires in a prospective Swedish birth cohort (n = 508). Fatty acid proportions were measured in maternal breast milk and erythrocytes. Allergy was diagnosed at 12 months of age by a pediatrician specialized in allergy. An increased maternal intake of cow’s milk during lactation, confirmed with biomarkers (fatty acids C15:0 and C17:0) in the maternal blood and breast milk, was associated with a lower prevalence of physician-diagnosed food allergy by 12 months of age. Intake of fruit and berries during lactation was associated with a higher prevalence of atopic eczema at 12 months of age. Our results suggest that maternal diet modulates the infant’s immune system, thereby influencing subsequent allergy development.
