Baby Obesity Through Cow's Milk

Formula from cow's milk may actually cause more weight gain. A study done at Monell Chemical Senses Center in Philadephia assigned 32 mothers to give their babies a formula based on cow's milk and asked 24 mothers to feed their babies another formula with a smaller and pre-digested proteins that are easier for babies to digest. These formulas are called "Protein Hydrolysate Formulas (PHF)". They have 35% more protein and more free amino acids than cow's milk formulas.

After 2 1/2 to 3 months, the babies that had the cow's milk had higher weight per length and weight per age than babies on PHF even with all the babies starting solid food at the same time. The researchers surmise that the reason for less weight gain is the "free amino acids in PHF do a better job of stimulating receptors in the mouth and gut that signal to the brain that the stomach is full and it's time to to stop eating.
