Cut back on red meat - processed and unprocessed - and you may dramatically lower your risk of type 2 diabetes. After analyzing responses to more than 442,000 questionnaires from studies over 28 years, researchers from the Harvard School of Public Health suggested that eating a daily serving of about 1.8 ounces of processed red meat such as hot dogs, sausages or bacon is linked to a 51 percent increase in the risk of type 2 diabetes. The same analysis showed that eating 3.53 ounces daily of unprocessed red meat boosts the risk by 19 percent. The research team also found that substituting a daily serving of nuts cut the risk by 21 percent, substituting low fat dairy led to a 17 percent risk reduction and eating whole grains lowered the risk by 23 percent. The study didn't find that processed and unprocessed red meat causes type 2 diabetes, but rather that increased risks of the disease are associated with the regular consumption of these meats. The study was published online August 10 in the American Journal of Clinical Nutrition.
