4 Health Benefits of Breastfeeding for Nursing Parents

Breastfeeding comes with a range ofhealth benefits for babies. According to the Centers for Disease Control and Prevention (CDC),breast milkis the best source of nutrition for most infants and lowers the risk for asthma, obesity, type 1 diabetes, sudden infant death syndrome (SIDS), and ear infections.

But breastfeeding isn’t just good for your little one. Studies have shown that it can lower the nursing parent's risk of certain diseases and health conditions. And now new research published in theJournal of the American Heart Associationshows that breastfeeding may also decrease the likelihood of heart disease and stroke.

“[The] benefits of breastfeeding for children are widely known. However, we believe that benefits for the mother are communicated poorly,” lead study author Lena Tschiderer, PhD, says. “Our analysis demonstrates clearly a relationship between breastfeeding and a reduced risk for cardiovascular disease in the mother’s later life.”

Decreased Risk of Cardiovascular Disease

Previously there were some inconsistencies about the strength of association and the relationship between the duration of breastfeeding and the development of cardiovascular disease. "We reviewed the available literature on this topic and provided overall associations between breastfeeding and maternal risk for cardiovascular disease," Tschiderer explains.

“The main finding of our study is that women who breastfed during their lifetime have a lower risk for future maternal cardiovascular disease compared to women who had given birth but never breastfed,” says Tschiderer.

The researchers analyzed data of more than one million women who had given birth and found that compared to women who never breastfed, women who breastfed had a 11% reduced risk of developing cardiovascular disease, a 14% decreased risk for coronary heart disease, a 12% reduced risk for stroke, and a 17% decreased risk of dying from cardiovascular disease.

Lower Risk of Postpartum Depression

CDC research based on the Pregnancy Risk Assessment Monitoring System (PRAMS) shows that about one in eight women in the U.S. experiencesymptoms of postpartum depression.In some states, rates may be as high as one in five women.

A study by researchers in the U.K. and Spain, published in the journalMaternal and Child Health, showed that mothers who breastfed were about 50% less likely to become depressed than mothers who did not breastfeed.

Another study, published in theJournal of Affective Disorders, found that women with multiple breastfed infants or a longer period of breastfeeding had a decreased risk of depression during the postmenopausal stage of life.

Lower Likelihood of Cancer

According to the American Cancer Society, about one in eight American women will develop invasive breast cancer.

Another study found that Australian women who breastfed for more than 13 months were 63% less likely to develop ovarian cancer than women who breastfed for seven months or less.Additionally, people whobreastfed multiple childrenfor more than 31 months in total could reduce their ovarian cancer risk by up to 91%, compared to women who breastfed for 10 months or less.

Decreased Risk of Diabetes

A reduced risk of type 2 diabetes may be anotherhealth benefit of breastfeeding. A study published in April 2020 inScience Translational Medicinesuggests that the energy needed to produce breast milk is part of the process that brings about permanent metabolic changes that may help protect against type 2 diabetes.

Those who breastfed babies for up to six months were 25% less likely to develop type 2 diabetes than those who didn't breastfeed at all. And breastfeeding for more than six months reduced the risk of type two diabetes by more than half.
