Oats, a staple breakfast food and a healthful snack option, provide important nutrients, such as dietary fiber, protein, calcium and iron. At only 166 calories per cup cooked, oats are diet-friendly, low in fat and cholesterol free. To help Americans plan a balanced diet, the U.S. Department of Agriculture establishes serving-size guidelines for oats and other foods.
Grain Guidelines
The USDA recommends that adults get the equivalent of five to eight servings of grains daily, half of which should be whole grains such as oats. In general, women should aim for the lower end of the recommended intake, while the higher end is more suitable for men. Ultimately, however, your total caloric needs, based on your weight goals and nutritional needs, affect the appropriate number of servings from the grain group for you. If you're cutting calories for weight loss, aim for five or six servings of grains to allow for adequate selections from other food groups.
Serving Size
A 1/2-cup portion of cooked oats is the equivalent of one serving -- or 1 oz. -- from the grains group, according to the USDA. Although the guidelines make it simple to track the number of grain servings you consume daily, you may prefer to eat more or less of a particular food and make adjustments in the portion size of other grain selections included in your menu on a given day. The main idea is to get enough grains without exceeding your calorie needs.
Whole-grain Benefits
Whole grains such as oats offer more of nature's nutrients than their refined grain counterparts. The refining process strips grains of iron, B vitamins and dietary fiber. Even though some nutrients, including B vitamins and iron, are often added back to refined grains, they don't contain the fiber that whole grains provide. Men need more than 30 g of fiber daily, and women need 20 g or more, according to the Harvard School of Public Health.
Considerations
While a 1/2-cup portion of oats meets the USDA criteria for a serving of whole grains, a 3/4-cup portion provides an additional gram of fiber without making a significant impact on your calorie consumption. When planning your menus, incorporate a variety of foods from every food group, including 2 to 3 cups of vegetables, 1.5 to 2 cups of fruit, 4 to 7 oz. of lean protein and healthful selections from the grains group. To maximize nutrition, limit sugar, fat and sodium added to oats. Season instead with fresh fruit, nuts and spices.
