UK researchers says that breastfeeding in infancy is associated with “a reduced risk of type 2 diabetes, with marginally lower insulin concentrations in later life, and with lower blood glucose and serum insulin concentrations in infancy.”
A systematic review of published studies identified 23 reports which examined the relation between infant feeding and type 2 diabetes in later life or risk factors for diabetes.
“Subjects who were breastfed had a lower risk of type 2 diabetes in later life than did those who were formula fed ,” write the researchers. “Children and adults without diabetes who had been breastfed had marginally lower fasting insulin concentrations than did those who were formula fed…”
