Fruits, vegetables and risk of renal cell carcinoma: a prospective study of Swedish women.

High intake of fruits and vegetables may guard against the development renal cell (kidney) carcinoma.

​This study evaluated the ingestion of fruits and vegetables in relation to the occurrence of renal cell carcinoma (RCC). The study population consisted of 61,000 Swedish women aged 40-76 years who provided dietary information at regular intervals. 

Researchers observed a significant reduction in the risk of renal cell carcinoma in women who consumed 5 or more servings of fruits daily compared to their colleagues who ate less than one serving per day. In contrast, regular drinking of fruit juice was found to increase the risk of kidney cancer in this study. "Our results suggested that high consumption of fruits and vegetables might be associated with reduced risk of RCC," the authors concluded.
