This study looked at 9,031 females between 9-15 years at baseline and collected dietary data through food frequency questionnaires. Authors asked questions about diet from birth until age 14 and looked at risk for benign breast disease (BBD). BBD is a known risk factor for developing breast cancer.
Key Findings: Higher BBD risk was associated with greater consumption of non-dairy animal foods over 10 years. Risk was also 40% higher with a lower consumption of nuts and peanut butter.
