Any type of whole grain can help lower your risk for type 2 diabetes, say Swedish and Danish researchers, whose study was published in the Journal of Nutrition.
While previous studies examining the effects of whole-grain foods on diabetes risk have primarily been done in the United States and focused on wheat, the goals of this research were to determine whether other whole grains — oats and rye, for example — have a similar effect, and to determine how many grams of whole grain per day you need to protect against type 2 diabetes.
The researchers divided 55,000 people into four groups, based on their intake of whole grains, and monitored their diabetes risk for 15 years. The type of whole grain didn’t make a difference when it came to lowering diabetes risk. What did matter in the study was the amount people ate. Study participants with the highest whole-grain intake — at least 50 grams per day — had a lower diabetes risk (34 percent lower in men, 22 percent lower in women) than those with the lowest intake of whole grains.
According to the Dietary Guidelines for Americans, adults should eat at least 3 to 5 servings of whole grains per day.
