Low-carb diet may stunt prostate tumors

NewsDaily: Science -- Low-carb diet may stunt prostate tumors

Tumor growth was stalled and survival rates lengthened in mice fed a low-carbohydrate diet, U.S. researchers found.

The study, published in the journal Prostate, found mice fed a low-fat but high-carbohydrate diets had larger tumors. The mice on a diet high in both fat and carbohydrates had the biggest tumors and the worst survival rates.

"This study showed that cutting carbohydrates may slow tumor growth, at least in mice," lead researcher Dr. Stephen Freedland, of Duke University Medical Center, in Durham, N.C., said in a statement. "If this is ultimately confirmed in human clinical trials, it has huge implications for prostate cancer therapy through something that all of us can control, our diets."

The researchers hypothesized carbohydrates in the diet affect the levels of serum insulin and a related substance known as insulin-like growth factor in the body.
