Low-carbohydrate diets may increase the risk of bowel cancer, according to Scottish scientists.

Researchers from Aberdeen's Rowett Research Institute believe there is a link between eating less carbohydrate and reducing cancer-fighting bacteria, according to BBC News. The acid, called butyrate, is produced by bacteria and helps kill off cancerous cells.

The researchers said they found low-carbohydrate regimes could cause a four-fold reduction in the cancer-fighting bacteria.
