Effects of Milk Consumption on Post Natal Growth and Circulating Hormones
Ghrelin, Leptin and IGF-I Levels in Breast-Fed Infants
Francisco Savino, MD
An emerging issue at this time for nutritional researchers is that of discovering breakthroughs in the understanding of
metabolic patterns and long-term effects related to breastfeeding.
In fact, it is already known that human milk is a source of different nutrients and biological compounds, especially hormones and growth factors
like insulin like growth factor I (IGF-I), ghrelin and leptin, which are involved in food intake regulation and metabolism. Their presence
is not yet detected in commercial milk formulae. Our finding suggests that breastfeeding influences ghrelin, leptin and IGF-I levels in infancy,
mainly during the first 4 months of life.
