By Kathryn Doyle NEW YORK (Reuters Health) – People who eat the most protein, especially from animal sources, are more likely to be diagnosed with type 2 diabetes, according to a study of European adults. Instead, it compared the diets of people who went on to develop diabetes and those who did not get the disease. “Several previous studies have found that higher intake of total protein, especially animal protein, are associated with long-term risk of developing diabetes,” said Dr. Frank Hu, from the Harvard School of Public Health in Boston. Hu, who was not involved in the new study, researches prevention of diabetes through diet and lifestyle.
