Research published in the International Journal of Cancer has shown that daily consumption of whole fruits and vegetables, especially bananas, is highly protective to kidney health. The results show that, over a long timeframe (13.4 years), women eating more than 2.5 servings of fruits and vegetable per day cut their risk of kidney cancer by 40%. Among the fruits, bananas were especially protective. Women eating bananas four to six times a week halved their risk of developing the disease compared to those who did not eat this fruit. The conclusion of the study is that frequent consumption of fruits and vegetables, especially bananas, cabbage and root vegetables, may reduce risk of kidney cancer. This is because bananas and many root vegetables contain especially high amounts of antioxidant phenolic compounds, while cabbage is rich in sulfur, necessary for effective detoxification of potential carcinogens.
