Calories
A 1-cup serving of couscous provides 176 calories, or 8 percent of a standard 2,000-calorie diet. Couscous contains fewer calories compared with a cup of rice or quinoa, which provide 205 and 222 calories, respectively. Including couscous in meals provides a low-calorie grain that can be added to a calorie-restrictive diet.
Protein
Protein is important for sustaining energy. Consuming a cup of couscous adds 6 g of protein in the diet, or 12 percent of the 50 g daily value recommended by the Food and Drug Administration. Other grain types typically provide a lower level of protein. Eating protein is important for bolstering muscle building after exercise. The body also uses protein to repair wounds and build enzymes.
Selenium
A 1-cup serving of couscous provides 43 mcg of selenium, or 61 percent of the 70 mcg FDA daily value. Selenium is an antioxidant commonly used to protect blood vessels from atherosclerosis, a condition that causes the buildup of plaque and narrowing of the arteries. This condition often results in heart stress and cardiovascular disease. Significant dietary sources of selenium are relatively rare, and including couscous in the diet helps meet the daily requirement.
Potassium
The potassium in the diet has several important functions, including regulating blood pressure and the heartbeat. Potassium helps control fluid balance, an important factor in blood pressure regulation. It also assists with muscle contractions. The heart is a muscle and requires potassium to prevent arrythmias, or irregularities of the heartbeat. A 1-cup serving of couscous provides 91 mg of potassium, or 39 percent of the 3,500 mg FDA daily value.
