Generous consumption of foods high in fiber, especially whole grains, may help thwart the development and spread of cancerous cells and tumors in the bladder.

The purpose of this study was to undertake a systematic meta-analysis on the relationship between dietary ingestion of fiber and the odds of acquiring bladder cancer. Researchers looked at the dietary choices and risk of bladder cancer among 574,726 participants who took part in 13 studies. 

Researchers found reduced risk of bladder cancer among participants who consumed high amounts of fiber-rich foods, especially whole grains. The data from this study suggest that individuals who want to improve their chances of avoiding bladder cancer should add more high-fiber foods to their diet.
