Fruits and veggies can reduce cancer

Researchers at the Roswell Park Cancer Institute in Buffalo, New York, have discovered that just three servings a month of raw broccoli or cabbage can reduce the risk of bladder cancer by as much as 40 per cent. The team of researchers 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 (ITCs), which are known to lower cancer risk. The effects were most striking striking in non-smokers.
Compared to smokers who ate fewer than three servings of raw cruciferous vegetables, non-smokers 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 non-smokers, those who ate this minimal amount of raw vegetables had a 40 per cent lower risk. However the team did not find the same effect for cooked vegetables as cooking tends to reduce 60 to 90 percent of ICTs.
