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.
