According to a new study by researchers at Harvard TH, women who consume many fruits and vegetables every day are less likely to develop breast cancer, especially aggressive tumors, than women who eat less fruit and vegetables. Chan School of Public Health. In their discoveries, cruciferous vegetables such as broccoli and yellow and orange vegetables had a particularly significant association with a risk of lower breast cancer
"Although previous studies suggest an association, their potency is limited, especially for specific fruits and vegetables and aggressive subtypes of breast cancer, "said first author Maryam Farvid, a research scientist in the Department of Nutrition." This research provides the most comprehensive picture of the disease. The importance of consuming large amounts of fruits and vegetables for the prevention of breast cancer. "
The study was published online July 6, 2018 in International Journal of Cancer .
The researchers analyzed the diet questionnaires submitted every four years by participants in the study on the health of nurses (88,301 women, from 1980) and the study on the health of nurses II (93,844 women, from 1991). Data on other potential risk factors for breast cancer such as age, weight, smoking and family history of cancer come from biennial questionnaires.
They found that women consuming more than 5.5 servings of fruits and vegetables a day had a lower risk of breast cancer than those who ate 2.5 servings or less. (A portion is defined as a cup of raw leafy vegetables, half a cup of raw or cooked vegetables, or half a cup of chopped or cooked fruit.)
To find out if the benefits of fruit consumption and Vegetables differ in types of breast cancers, the researchers performed a tumor hormone receptor status analysis and molecular subtype. They found that higher consumption of fruits and vegetables was particularly associated with a lower risk of more aggressive tumors, including ER-negative, HER2-enriched and basal type tumors
. fiber intake, but the benefits of fruits and vegetables found in this study appear to be independent of their fiber content, according to the researchers. This suggests that other constituents of these foods, such as antioxidants and other micronutrients, may also be important in reducing the risk of breast cancer.
"Although a diet containing a lot of fruits and vegetables is associated with," said lead author Heather Eliassen, associate professor at Harvard Medical School and at Harvard Chan School and associate epidemiologist at Brigham Hospital and Women & # 39; s.
