SOUTH LAKE TAHOE, Calif., Oct. 15 (UPI) -- Eating tomatoes and fish, keeping a healthy weight and avoiding meats cooked at high temperatures may help men alleviate prostate cancer, U.S. researchers say.

"What we’re trying to determine is if men with low grade prostate cancer can manage their disease with these kinds of nutritional interventions and delay or avoid the need for more aggressive treatments, all of which carry a risk of side effects that can adversely affect physical function and quality of life," June Chan of the University of California San Francisco said in a statement.

"In combination with other studies, the potential we see for these everyday supplements or foods to help men avoid or delay treatment is promising."

One-quarter to one-half of all cases of diagnosed prostate cancer in the United States and Europe are considered candidates "active surveillance," which researchers hope leads to better outcomes for patients with low-risk disease.

One aspect of this management approach may include specific dietary modifications such as minimizing intake of red, processed or well-done meats, Chan said.

The findings were presented at the Prostate Cancer Foundation’s annual scientific retreat at Lake Tahoe, Nev.
