Breastfeeding for any amount of time linked to lower blood pressure in toddlers, study finds By Sarah Molano, CNN enablePagination: false (CNN) — Toddlers who were breastfed for any amount of time had lower blood pressure than those who were not breastfed at all, according to a new study, suggesting once again that "breast is best" for health. The reduction in blood pressure found in the study "is of clinically important magnitude and surprising," Dr. Lori Feldman-Winter told CNN in an email. Feldman-Winter, who was not involved in the study, is the chair of the American Academy of Pediatrics Section on Breastfeeding.
