Fat 'disrupts sugar sensors causing type 2 diabetes'

US researchers say they have identified how a high-fat diet can trigger type 2 diabetes, in experiments on mice and human tissue. Writing in the journal Nature Medicine, they say that fat interferes with the body's sugar sensors. The authors argue that a deeper understanding of the processes involved could help them develop a cure. Diabetes UK said the study was interesting and a "theory worth investigating further". One of the main risk factors for type 2 diabetes is being overweight - rising obesity levels have contributed to a doubling of diabetes cases in the last 30 years
