Lipids in breast milk and infant formula, and lipid nutrition

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 < .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.

Limit Of Quantitation

Leptin is a 16 kDa lipophilic protein hormone secreted by adipocytes and its most significant function is to inform the brain with negative feedback that regulates food intake. Recently the protein found in human breast milk was related to breast feeding and onset of obesity, and the evidence of a low probability to develop pediatric obesity in children fed with breast milk was also confirmed. Since leptin could have a critical role, its quantitation both in human breast, bovine milk and in infant formula products is interesting. For this reason, we developed an analytical method based on immunoaffinity purification followed by an analysis with nano-High Pressure Liquid Chromatography coupled with High Resolution Mass Spectrometry analyzer (nano-HPLC-HRMS) to identify and quantify leptin in milk samples and performed a pilot study using samples of human breast milk, bovine milk and infant formulas. With an obtained lower limit of quantitation (LLOQ) of 100 ng mL−1 we quantified leptin in human breast milk finding an average of 6.70 ng mL−1. Our results show that leptin was under LLOQ both in bovine milk and in infant formula products. In conclusion, the developed analytical method here described was suitable to quantify leptin in milk samples with a good sensitivity and selectivity, and without the use of radioactive reagents.

The Ideal

AbstractBreast-feeding is the ideal nutrition for a newborn’s integral necessities. It seems crucial therefore to know its composition in order to provide suitable infant formula when required. Of these, polyamines (with lactation and the microbiota being its intestinal source) are involved in the development of gut epithelium and immunity. Safety concerns limit human intervention studies. Therefore, we studied the amounts of polyamines supplied by breast milk (varying among mothers) or infant formula feeding, up to day 30 postpartum, in the faeces of newborns. Independent samples (68) of breast milk from fifty-nine healthy Caucasian woman (day 0, 1, 3, 5, 7, 15 and 30 postpartum) who had natural deliveries after week 38, same-day faeces of newborns when available (eighty-one from breast milk and fifty-five from infant formula fed) and six infant formulas were collected and the polyamine content was determined by HPLC. In breast milk, polyamines and isoamylamine (a primary amine), with inter-individual variations, increased over time (with a higher content of spermidine; no other amines were present). Overall, they were much higher than in infant formula. By the 2nd week after birth, polyamines, cadaverine and tyramine, but not isoamylamine, were higher in the faeces of those fed infant formula compared with those fed breast milk. Cadaverine and tyramine could be used to predict the feeding type used for newborns. The differences in the content may be related to distinct colonisation of amine-producing bacteria, which can be established by polyamines. Further studies are required to determine the clinical utility of these findings.
