[Recommendation] Fill up on fruits and veggies [Why] 
Although not proven, a diet high in fruits and vegetables may afford some protection against breast cancer. An analysis of 17 studies on breast cancer risk and diet found that high consumption of vegetables was associated with a 25% decreased risk of breast cancer compared with low consumption.65 The same report analyzed 12 studies that found high consumption of fruit was associated with a 6% reduction of breast cancer incidence compared with low consumption. However, when data from only the eight largest and best studies were combined, high intake of fruits and/or vegetables did not correlate with protection from breast cancer.66 Therefore, the protective effect of fruit and vegetable consumption against breast cancer remains unproven.67
