Yes, roasted carrots are good for you! According to the USDA, just 1 cup of sliced carrots contains 50 calories, 1.13 gram of protein, 3.4 grams of fiber, 0.3 grams of fat, and 5.78 grams of sugar. Not to mention an impressive amount of Vitamin A which has been linked to eye health, plus potassium and calcium. You can easily adjust the seasoning level and use olive oil instead of butter for a monounsaturated fat option.
