Just three servings a month of raw broccoli or cabbage can reduce the risk of bladder cancer by as much as 40 per cent, researchers have found.
The scientists surveyed 275 people who had bladder cancer and 825 people without cancer. They asked especially about cruciferous vegetables such as broccoli and cabbage.
These foods are rich in compounds called isothiocyanates, which are known to lower cancer risk. The effects were most striking in nonsmokers according to the researchers from the Roswell Park Cancer Institute in New York.
Compared to smokers who ate fewer than three servings of raw cruciferous vegetables, nonsmokers who ate at least three servings a month were almost 73 per cent less likely to be in the bladder cancer group, they found.
Among both smokers and nonsmokers, those who ate this minimal amount of raw veggies had a 40 per cent lower risk. But the team did not find the same effect for cooked vegetables.
