Whole grains such as oats contain fiber, which when consumed as part of a healthy diet can reduce the risk of heart disease, type 2 diabetes, and weight gain. The 2005 USDA Dietary Guidelines recommend choosing the right carbohydrates, like whole grains. Each CLIF ZBaR contains 7 grams of whole grains and 3 grams of total fiber from oats, which is as many whole grains as found in ¼ cup brown rice or cooked barley and twice the fiber.
