Girls Who Eat Peanut Butter May Lower Their Risk of Breast Cancer

Young girls may lower their chance of developing breast cancer later in life by eating peanut butter. This comes from a study conducted by the Washington University School of Medicine in St. Louis and Harvard Medical School.

According to the research, girls ages 9 to 15 who consumed peanut butter or nuts regularly were 39 percent less likely to have benign breast disease by age 30. While these type of tumors are noncancerous, the study points out that developing them can increase the risk of having breast cancer at a later date.

"The findings are based on the health histories of 9,039 U.S. girls enrolled in The Growing Up Today Study from 1996 through 2001," Washington University explained in a statement. "Later, from 2005 through 2010, when the study participants were 18 to 30 years old, they reported whether they had been diagnosed with benign breast disease that had been confirmed by breast biopsy."

Additionally, soybeans, lentils, corn and beans may also prevent benign breast disease, yet the research shows participants consumed these foods at a much lower rate, thus the evidence wasn't as strong when compared to peanut butter. The study was funded by the Breast Cancer Research Foundation and the National Institutes of Health.
