Calories Fat and Protein

In 1/2 cup of boiled, unsalted brussels sprouts, you get just 28 calories and only trace amounts of fat. Eating Brussels sprouts as a side dish, instead of a higher calorie food, can help you manage your weight. Brussels sprouts provide 2 g of protein per 1/2 cup. Although the sprouts lack several of the amino acids necessary to make it a complete protein like meat or dairy, you can include grains, such as brown rice or whole wheat pasta, in your diet to obtain all the amino acids you need.
