Red Meat May Increase Diabetes Risk
The study, published online ahead of the October print edition of the American Journal of Clinical Nutrition, also finds replacing red meat with healthier proteins, such as low-fat dairy, nuts or whole grains, can significantly lower the risk of type 2 diabetes.
Study leader An Pan, a research fellow in the Harvard School of Public Health and senior author, a professor of nutrition and epidemiology at HSPH, and colleagues analyzed questionnaire responses from 37,083 men tracked for 20 years in the Health Professionals Follow-Up Study; 79,570 women tracked for 28 years in the Nurses' Health Study I; and 87,504 women tracked for 14 years in the Nurses' Health Study II.
They also conducted a meta-analysis, combining data from their new study with data from existing studies that included a total of 442,101 participants, of which 28,228 developed type 2 diabetes.
The researchers find a daily 100g serving of unprocessed red meat -- the size of a deck of cards -- was associated with a 19% increased risk of type 2 diabetes, while one daily serving of processed meat such as one hot dog, a sausage or two slices of bacon -- was associated with a 51% increased risk.
