A diet rich in whole grains, which are naturally high in fiber, is associated with lowering a person’s risk for various health problems. Overall, Americans are eating more whole-grain foods than ever before, researchers from the Friedman School of Nutrition Science and Policy at Tufts University report in a new study, published November 30 in the American Journal of Clinical Nutrition. However, the increase in whole-grain intake over the past two decades could be 39.5% or 61.5%, depending on which definition of a whole-grain food is being used. In addition, Americans’ mean consumption of whole-grain foods remained far below the recommended consumption of at least three ounces each day and varied considerably by each definition.
