Women Eating High fruit, vegetable may cut risk of breast cancer , especially of aggressive tumors , than those who eat fewer fruits and vegetables, according to a new study led by researchers from Harvard T . H . Chan School of Public Health .

In their findings , cruciferous vegetables such as broccoli , and yellow and orange vegetables, had a particularly significant association with lower breast cancer risk . “ Although prior studies have suggested an association , they have been limited in power , particularly for specific fruits and vegetables and aggressive subtypes of breast cancer , ” said first author Maryam Farvid , research scientist in the Department of Nutrition. “ This research provides the most complete picture of the importance of consuming high amounts of fruit and vegetables for breast cancer prevention . ”
The study was published online July 6 , 2018 in the International Journal of Cancer .

How The Research was done


The researchers analyzed diet questionnaires submitted every four years by participants in the Nurses ’ Health Study (88 , 301 women , starting in 1980 ) and the Nurses ’ Health Study II ( 93 , 844 women , starting in 1991 ). Data on other potential breast cancer risk factors such as age , weight , smoking status, and family cancer history were taken from biennial questionnaires . They found that women who ate more than 5 . 5 servings of fruits and vegetables each day had an 11 per cent lower risk of breast cancer than those who ate 2 . 5 or fewer servings. (A serving is defined as one cup of raw leafy vegetables, half a cup of raw or cooked vegetables, or half a cup of chopped or cooked fruits).

To find out whether the benefits of fruit and vegetable consumption differed among various types of breast cancers, the researchers conducted an analysis by tumor hormone receptor status and molecular subtype . They found that higher consumption of fruits and vegetables was particularly associated with lower risk of more aggressive tumors including ER-negative, HER 2 - enriched , and basal - like tumors .
