Mothers of small babies should not panic into over-feeding their children, experts are warning.
A study has revealed that faster weight gain in infancy could make them fat in later life.
Infants who were fed milk enriched with nutrients had higher body fat mass than those who were given standard formula, according to the study.
Previous studies have shown a link between over-nutrition in childhood and overweight adults in animals, but the researchers said this is the first demonstration in humans when other factors such as the size of mothers is ruled out.
Body fat mass in five to eight-year-olds was 22 per cent to 38 per cent greater in those who were given nutrient-enriched milk as babies than those who had standard formula, according to a team based at the University College London Institute of Child Health.
