Breastfeeding may not protect babies, mothers told

Michael Kramer, a professor of paediatrics who has advised the World Health Organisation and Unicef, said that much of the evidence used to persuade mothers to breastfeed was out of date.
He said evidence that breastfeeding protects against obesity was flawed. He told the Times: The evidence it protects against allergies and asthma is also weak. And there is very little evidence that it reduces the risk of leukaemia, lymphoma, bowel disease, type 1 diabetes, heart disease and blood pressure.
