In turn, the study published in the" International Journal of Cancer "analysis Dietary questionnaires presented every four years by participants in the Nurses & Health Study (88,301 women, in 1980) and the Nurses' Health Study II (93,844 women, in 1991) Data on other possible risk factors for breast cancer, such as age, weight, smoking and family history of cancer, were obtained from biennial questionnaires
Vegetables differ between different types of breast cancer, the researchers performed an analysis according to the tumor hormone receptor status and the molecular subtype. higher consumption of fruit and vegetables was associated in particular at a lower risk of more aggressive tumors, including ER-negative, HER2-enriched and basal tumors.
Previous work in this research group focused on risk reduction. Breast cancer with a higher fiber intake, but the benefits of fruits and vegetables found in this study seem to be independent of their fiber content, according to the researchers. This suggests that other components of these foods, such as antioxidants and other micronutrients, could also play an important role in reducing the risk of breast cancer.
"While a diet with many fruits and vegetables is associated with many other health benefits, our results can give women greater momentum to increase their consumption of fruits and vegetables" ] warns senior author Heather Eliassen, associate professor at Harvard Medical School and at Harvard Chan School, and assistant epidemiologist at Brigham and Women's Hospital.
