Men with prostate cancer significantly increase their chances of dying from the disease if they fail to eat healthily after being diagnosed, a study has found.
The study, was conducted by researchers from Harvard T.H. Chan School of Public Health and investigated the diets of 926 men diagnosed with prostate cancer for an average of 14 years after their diagnosis.
Researcher Dr Jorge Chavarro, from the Harvard TH Chan school of public health in Boston, said: “There is currently very little evidence to counsel men living with prostate cancer on how they can modify their lifestyle to improve survival.
“Our results suggest that a heart-healthy diet may benefit these men by specifically reducing their chances of dying of prostate cancer.”
Those most wedded to a “western” diet containing a lot of red and processed meat, fat and refined grains were two-and-a-half-times more likely to die from a prostate cancer-related cause, than men likely to eat healthy foods.
Western-diet consumers had a 67% increased risk of dying, while overall death rates of men choosing a “prudent” diet rich in vegetables, fruit, fish and beans were reduced by 36%.
The findings appeared in the journal Cancer Prevention Research.
Previous studies have suggested that some foods may slow down the growth of prostate cancer or reduce the risk of it returning after treatment, but the evidence is limited.
Examples include soya products, pulses such as kidney beans, chickpeas and lentils, broccoli, kale and other cruciferous vegetables, cooked and processed tomatoes, green tea and pomegranate juice.
Good food sources of the mineral selenium, but not supplements, are also said to be beneficial. They include Brazil nuts, liver, kidney, fish, seafood and poultry.
