Breastfed babies are less likely to have certain cardiovascular disease (CVD) risk factors in adulthood than their bottle-fed counterparts, researchers reported at the American Heart Association’s Scientific Sessions 2007. “Having been breastfed in infancy is associated with a lower average body mass index (BMI) and a higher average HDL (high-density lipoprotein or “good” cholesterol) level in adulthood, even after accounting for personal and maternal demographic and CVD risk factors that could influence the results,” said Nisha I. Parikh, M.D., M.P.H., author of the study and a cardiovascular fellow at the Beth Israel Deaconess Medical Center in Boston, Mass. A lower BMI and high HDL both protect against CVD. The study, which used data from two generations of participants in the Framingham Heart Study, showed that middle-aged adults who were breastfed as infants were 55 percent more likely to have high HDL cholesterol than to have low HDL cholesterol. Low HDL was defined as levels of less than 50 mg/dL for women and less than 40 mg/dL for men. HDL is known as “good” cholesterol because high levels help protect against heart disease and stroke.
