London, Apr 24 : Breast milk has less protein than formula, a new study has claimed.
It has been believed that formula-fed babies, who tend to be bigger, are "programmed" to store fat and so have a higher risk of childhood obesity.
Now, an international study of 1,000 babies, published in the American Journal of Clinical Nutrition, has suggested that protein levels in formula should fall.
The study, which was carried out in Belgium, Italy, Germany, Poland and Spain, included babies born between 2002 and 2004.
