A Low-Carb Diet Stunts Prostate Tumor Growth

A reduction in insulin production brought on by a diet low in carbohydrates can stall the growth of prostate tumors, according to a new study performed on mice.

Insulin, and a related substance known as insulin-like growth factor (IGF), have been linked with the growth of prostate tumors in previous research. For the new study, researchers divided 75 mice into groups eating either a low-carbohydrate diet, a low-fat but high-carbohydrate diet, or a diet high in both fat and carbohydrates.

The mice on the low-carbohydrate diet had the longest survival and smallest tumor size. Low-fat mice had shorter survival and larger tumors, and mice on the high-fat, high-carb diet had the worst survival and biggest tumors.
