By Kathryn Doyle (Reuters Health) – Organized diet and exercise programs can stave off diabetes for those at risk, according to a new recommendation. The Community Preventive Services Task Force, an independent, unpaid group of public health and prevention experts who develop recommendations for community health, commissioned a review of 53 studies describing 66 combined diet and physical activity promotion programs. The Task Force found strong evidence that these programs are effective at reducing the number of new cases of diabetes, according to a report in Annals of Internal Medicine.
