Breastfeeding, in the absence of formula feeding, appears to have a protective effect on childhood obesity among Canadian school children. The researchers said: “Strategies and social policies are needed to promote exclusive and longer breastfeeding duration and should be integrated with comprehensive efforts to prevent childhood obesity and to reduce the burden of chronic diseases in the long term.” (Journal of Maternal Child Health, February 6, 2015)
