Leptin is a hormone mainly produced by the adipose tissue [1], but also by the stomach [2, 3, 4], placenta [5, 6] and mammary epithelial cells [7]. The stomach can produce and store leptin and release it in response to food intake [3, 4, 8]. Also leptin is produced by the placenta and potentially plays a role in fetal and neonatal growth. Leptin is present in maternal milk and this leptin could be absorbed by the immature gastric mucosa of neonatal rats [9, 10]. Previous results of our laboratory show that during the first 15 days of life, maternal milk-borne leptin is the main source of gastric leptin and the increase of endogenous leptin expression in the stomach of neonates is related to the change of diet from milk to a solid chow diet [10].

The biological role of milk-borne leptin is not known. Neither is the biological role of milk-borne leptin or its implication in post-neonatal development known. However, there is large epidemiological evidence that food during early life does...
