A Low-Fat Diet May Help Prevent Prostate Cancer

Posted May 21 2008 1:05pm

Research has shown that eating less polyunsaturated fat, which is typically found in baked and fried foods, helps prevent prostate cancer in mice.

The research was performed by the University of California, Los Angeles, and the scientists believe it to be the first of its kind in a mouse model that closely mimics human cancer.

The researchers found that mice that ate a low-fat diet (only 12% of calories from fat) had a 27% reduced rate of prostate cancer compared to mice who ate a more traditional Western-type diet (40% of calories from fat). They also found that precancerous prostate cells grew more slowly in the mice that ate the low-fat diet.

Senior author William Aronson, a Jonsson Cancer Center researcher, stated that some of his previous studies have shown that a low-fat diet slowed the growth of aggressive human prostate cancer in mice and helped them live longer.

Aronson is planning a short-term study with men who will be assigned a diet high in polyunsaturated fat or a low-fat diet with fish oil supplements.

I think this just adds to a pile of evidence of just how bad the traditional American diet can be. I have posted before about how fried foods are linked to metabolic syndrome and how trans fat leads to coronary heart disease. I think it is important that the researchers are planning a follow-up study with fish oil supplements. Certain fats have been shown to provide health benefits, and I have posted before about the benefits of omega-3 fatty acids (such as fish oil).
