Large Prospective Study Supports Link Between Meat Consumption And Diabetes

Here's another study that provides evidence for a link between meat consumption and risk for type 2 diabetes:

Association Between Dietary Meat Consumption And Incident Type 2 Diabetes: The EPIC-Interact Study, Diabetologia, January 2013

Researchers investigated food intake from 16,835 participants of the InterAct project, "an examination of the interaction of genetic and lifestyle factors on the incidence of type 2 diabetes." The InterAct project, or EPIC-InterAct study, is a large prospective study nested within the EPIC study (European Prospective Investigation into Cancer and Nutrition). InterAct drew participants from 8 countries, accounting for variations in meat consumption across Europe.

After adjusting for confounders, researchers found a significant positive association with type 2 diabetes and each of the following: total meat consumption, red meat consumption, and processed meat consumption. The association was dose-dependent; for every 50 gram increase (about 2 ounces) there was a corresponding increase in diabetes risk. For women, there was also an association between poultry consumption and diabetes.

Their conclusion:
"This prospective study confirms a positive association between high consumption of total and red meat and incident type 2 diabetes in a large cohort of European adults."
