This study included 9031 adolescent girls and looked at risk of benign breast disease (BBD) with diet. Specifically, authors looked at if consumption of peanuts/peanut butter/other nuts could reduce risk of BBD, even if participants reported consuming alcohol. Adolescent alcohol consumption is associated with an increased risk of BBD, and BBD is an established risk factor for breast cancer.
Key Findings: The results showed that adolescent alcohol consumption was associated with increased BBD risk. However, that risk was attenuated when participants reported consuming peanuts/peanut butter/other nuts. The authors concluded that "for high school females who drink, their BBD risk may be attenuated by consuming nuts."
