Breast milk is an ideal food for babies, but not only do they benefit, according to two recent research. A study on 40,000 cases? Appeared in Annals of Oncology? has discovered that breastfeeding can help protect women from one type of breast cancer, while another published in Annals of Internal Medicine? suggests that it may restart the mother's metabolism after pregnancy, to prevent women with gestational diabetes from becoming lifelong diabetics. The findings complement previous research that shows that women who breastfeed have a lower risk of breast and ovarian cancer, type 2 diabetes, and rheumatoid arthritis. Breastfeeding can also promote cardiovascular health, including a healthy blood pressure. During lactation insulin levels are lower and there is less demand. While the woman breastfeeds her baby, the pancreas can rest, allowing her to recover from the demands of pregnancy.
