Reducing carbs reduced polyps reduced cancer in mice.

50k Americans die each year from this type of cancer?!

Colorectal cancer is a scourge of modern times,killing 50,000 Americans every year. It’s responsible for a heavier death toll than any other cancer besides lung cancer and, when it comes to women, breast cancer.

And new research, which was published last week in Cell, has provided insights into the dangerous link between colorectal cancers and modern diets heavy in wheat, rice, and other complex carbohydrates—diets that became possible with the advent of agriculture.

University of Toronto scientists led research that suggests a common type of gut-dwelling bacteria breaks down carbs into certain metabolites that can lead to cancer. These metabolites appear to cause cells that line the colon to divide and proliferate rapidly, forming polyps. These polyps, which can grow into a cancer, are the abnormal growths that your doctor is probing for when they subject you to a colonoscopy.
