Breast cancer awareness month begins today, and a recent study finds girls who eat peanut butter or nuts on a regular basis, may be less likely to develop benign breast disease.
Washington University researchers looked at the eating habits of more than 9,000 girls ages 9-15. They followed up with them when they were between 18 and 30 years-old.
Researchers say girls who ate peanut butter or nuts two times each week were 39 percent less likely to have developed benign breast disease by age 30 than those who never ate them.
Researchers say benign breast disease is non-cancerous, but can increase the chance of breast cancer later in life.
Some of the more common conditions include hyperplasia, cysts, or radial scars.
The findings suggest other foods in the peanut family may offer protective benefits, but more studies are needed.
