Food Navigator - Ingredients, Food Additives & Nutrition (fibers, proteins, enzymes, food safety, science, ingredients): "Infant formula - does it really cause obesity?
"A major trial on European children is to examine how early childhood diet can reduce the risk of obesity in later life. The findings could lead to development of new infant foods and reformulating of protein contents.

Obesity is increasing steadily among European children, causing concern for the serious consequences seen in adulthood. Nutrients supplied during infancy are thought to have a lasting, programming effect on later obesity risk. There has also been some evidence to show that infants fed formula milk are more likely to become obese than breastfed infants although two studies published last week appeared to disprove this theory.

However researchers on the Chopin project, funded by the EU Framework, point to evidence showing that longer duration of breastfeeding has a marked effect on reducing later obesity risk. One hypothesised reason for this, to be tested in the new trial, is the relative higher protein content of some infant formulae compared with breast milk. ..."
