One cup of cooked grits contains about 38 grams of energy-enhancing carbohydrates, 182 calories and 1 gram of fat. These numbers do not include additives, such as butter, sugar and milk, which may increase the calorie and carbohydrate counts dramatically.
Grits are made from dried corn kernels from which the hull and germ have been removed. The resulting "hominy" is ground into fine granules to create grits, which store well and are cooked by boiling in water. The United States Department of Agriculture recommends getting about 60 percent of one's recommended daily allowance of calories from carbohydrates. In a 2,000-calorie diet, that amounts to between 225 and 325 grams of carbs each day. Other factors, including age, height and weight, and the presence of diabetes, help determine the number of carbohydrates each person should consume.
