Tomatoes are a nutrient-dense food, meaning they are jam-packed with nutrients, but don't have a lot of calories. Lipids, carbs and protein are the three types of macronutrients your body breaks down for energy. The primary macronutrient in tomatoes is carbohydrates, although they do have trace amounts of fat and protein.
Corn, white and sweet potatoes, lima and dried beans, and peas are starchy vegetables because of their high carbohydrate concentration. Other vegetables, including beets, carrots, onion, cauliflower, broccoli, and leafy greens, are nonstarchy vegetables because they have insignificant amounts of carbohydrate.
