Researchers from Kaiser Permanente in Oakland, California, monitored women who had developed gestational diabetes during pregnancy for two years after birth. Their study, which was published in the [Annals of Internal Medicine](http://annals.org/article.aspx?articleid=2471594) on Monday, found that their risk of developing Type-2 diabetes was cut by half the longer they breast-fed, [reports the New York _Times_](http://well.blogs.nytimes.com/2015/11/23/breast-feeding-is-good-for-mothers-not-just-babies/?%5Fr=1). “Pregnancy is a metabolic challenge,” Erica P. Gunderson, the study’s lead author, told the New York _Times_. Glucose levels are lower during lactation and there is less demand for insulin. “One of the possible biologic explanations is that this gives the woman’s pancreatic beta cells a bit of a break, allowing for recovery from the demands of pregnancy.” The results come at the heels of [findings published late last month](http://www.ncbi.nlm.nih.gov/pubmed/26504151), which found that breast-feeding may help protect women from hormone receptor negative tumors— an incredibly aggressive type of breast cancer. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4125599/breast-feeding-diabetes/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4125599/breast-feeding-diabetes/"},"headline":"Breast-Feeding May Protect Against Type-2 Diabetes","datePublished":"2015-11-24T14:58:49.000Z","dateModified":"2026-02-22T12:52:32.831Z","description":"Infants are not the only one to gain from breast milk","url":"https://time.com/4125599/breast-feeding-diabetes/","keywords":["Pregnancy","health"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt4adc49807112db4c/69887290ab6d772ddc6a74b8/breastfeeding.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Tara John","jobTitle":null,"url":"https://time.com/author/tara-john/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt4adc49807112db4c/69887290ab6d772ddc6a74b8/breastfeeding.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Mother breast-feeds baby","caption":"Mother breast-feeds baby","creditText":"Ricardo Dias—EyeEm/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/pregnancy/","name":"Pregnancy"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4125599/breast-feeding-diabetes/","name":"Breast-Feeding May Protect Against Type-2 Diabetes"}}]}] ```
