Tomatoes Tomatoes and carrots are high in beta carotene, which helps your body absorb the lycopene in tomatoes and may reduce your chances of prostate cancer by 32%.

One study showed that men who consumed adequate amounts of selenium for 41 years were 63 percent less likely to die from prostate cancer.

Canadian researchers have found that foods with sufficient soluble fiber can lower PSA levels in the body, which is a marker for prostate cancer.
