Fruits and vegetables low in calories include medium-size apples, bananas, blueberries, grapes, spinach, bell peppers, broccoli, green beans and mushrooms. These fruits and vegetables contain low calories; according to the Center For Disease Control, all pack fewer than 100 calories per serving. These items add nutrition and volume to meals, such as sandwiches, soups and salads, without extra calories.
Per serving, one cup of blueberries contains approximately 80 calories, while a medium-size apple contains 72 calories, and a medium-size banana produces just over 100 calories. A cup of grapes — one standard serving — offers 100 calories. Among the low-calorie vegetables, bell peppers and broccoli take the lead. A one-cup serving of either offers 30 calories. One cup of steamed green beans provides 44 calories, while one cup of carrots provides 45 calories. Consuming these fruits and vegetables fits adds variety to many popular dishes, and adds flavor and nutrition while eliminating extra calories. Substituting one cup of spinach or mushrooms for an egg or slice of cheese in a breakfast sandwich reduces caloric content, as does filling a bowl with more chopped or sliced fruit and less cereal. These fruits and vegetables make healthy, appetizing snacks on their own. However, they pair well with other low-calorie healthy snacks, such as nuts and hummus.
