Will Eating PB&J Protect Girls from Breast Health Problems?
That lunchtime staple may actually be doing more good than we originally thought. A new study from researchers at the Washington University School of Medicine in St. Louis, Dana-Farber Cancer Institute and Harvard Medical School linked peanut butter consumption and lower risk of benign breast disease, says the Huffington Post.
Benign breast disease is a noncancerous condition where growths form in the breast due to injury or infection. The study did not look at links between peanut butter and cancerous lumps. Researchers analyzed data from over 9,000 girls ages 9 to 15 years old. The girls reported what they ate on a questionnaire. Girls who ate peanut butter at least twice a week during childhood and adolescence had a 39 percent lower risk of benign breast disease than girls who didn’t pack PB&Js for lunch.
Researchers want to stress that there’s a connection between peanut butter consumption and breast health but peanut butter and jelly won’t prevent benign breast disease.
