Consuming more than ten servings a week of tomatoes and beans lowers the risk of prostate cancer, according to a new study from researchers at the University of Bristol.
The findings expand on previous research and suggest that men should consume foods rich in lycopene and selenium, which are found in tomatoes and beans respectively, to help prevent the onset of a disease that kills about 30,000 men in the United States each year.
The study compared the diets of more than 1,800 men between the ages of 50 and 69 who had prostate cancer to the diets of more than 12,000 of their cancer-free peers.
While the study’s conclusions provide some dietary guidance, researchers say more work needs to be done to develop further dietary guidelines.
“Our findings suggest that tomatoes may be important in prostate cancer prevention. However, further studies need to be conducted to confirm our findings, especially through human trials,” said Vanessa Er, a researcher at the University of Bristol who led the study. “Men should still eat a wide variety of fruits and vegetables, maintain a healthy weight and stay active.”
