| Have you ever heard the theory that certain foods have a negative caloric effect, meaning they burn more calories during the digestive process than they contribute? (Celery and apples are often cited as examples.) |
Turns out the negative calorie theory is a myth. But that doesn't mean some foods aren't incredibly low-calorie and super-nutritious. Here's a list of Health.com's favorite almost-zero-calorie foods, with recipes.

This delicate, peppery green is amazingly low in everything you don't want, especially calories, fat, saturated fat, and cholesterol. It is, however, loaded with crunch and packed with fiber, vitamins A, C and K, and other nutrients, including potassium.
Perfect in salads, soups, or anywhere you would use leafy greens, arugula may even boost your romantic life! Evidence suggests that the minerals and antioxidants packed into dark, leafy greens are essential for our sexual health because they help block absorption of toxins that dampen the libido.

Asparagus is traditionally known as a detoxifying food, because it contains high levels of an amino acid that act as a diuretic, flushing excess fluid out of your system. It also helps speed the metabolism of alcohol and other toxins (it's a surprising hangover remedy).
Asparagus is also a powerhouse of vitamins and minerals, including vitamins A, C, E, and K, B6, folate, iron, copper, and even protein. We love the tender shoots in their most natural form, raw and tossed into salads, or steamed.

Broccoli is amazingly low in calories, but it always makes our list of the top superfoods for a reason. Not only is it packed with fiber, vitamins, and minerals, it contains powerful antioxidants that may improve your odds of breast cancer survival and reduce the risk of colon cancer.
The chemical in broccoli responsible for the protective effect is called sulforaphane, and yes, it gives broccoli its slightly bitter flavor.

Clear beef, chicken, miso, seafood, or vegetable broth is a dieter's secret weapon, nourishing and filling your body for almost zero calories, especially if you toss in leafy greens and lean meat. Broth is the ultimate 'high volume food,' meaning you can eat large amounts for very few calories and still feel full. It all comes down to calories per bite, or in this case, slurp.
"By choosing foods that have fewer calories per bite, your portion size grows, but your overall calorie count decreases," explains Barbara Rolls, PhD, the creator of Volumetrics and author of the new book The Ultimate Volumetrics Diet. "So you end up with a satisfying amount of food."

Purple cabbage also contains anthocyanins and other natural chemicals that boost cellular repair and block cancer growth. Eat up!

Black coffee is one of the lowest-calorie drink choices around, and it's a great weight loss ally. Coffee alters levels of gut peptides, the hormones naturally released to control hunger or fullness.
Coffee drinkers may be at lower risk of liver and colon cancer, type 2 diabetes, and Parkinson's disease, and it may help you live longer: A 2008 study found that women who drank coffee regularly—up to six cups a day—were less likely to die of various causes during the study than their non-coffee-drinking counterparts.
What's more the caffeine in coffee can speed up metabolism and fat-burning, which helps lower your risk of type 2 diabetes and obesity.

Remember The Grapefruit Diet? There may be something to that. Studies reveal that, on average, women who consumed any amount of grapefruit or grapefruit juice weighed nearly 10 pounds less and had a 6 percent lower body mass index (BMI) than their non-grapefruit-eating counterparts.
A powerhouse for heart health, grapefruit contains vitamin C, folic acid, and potassium, along with pectin, a soluble fiber that may be a strong ally against atherosclerosis. Pink and red varieties also have vitamin A and lycopene, a phytochemical that protects arterial walls from oxidative damage.

Meaty and incredibly low-cal, mushrooms are also incredibly diverse. White button, Portobello, shiitake, and Maitake are just a few of the varieties you'll find in your grocery store. Fortunately, just about all mushrooms contain some form of immune-boosting antioxidants, along with potassium, B vitamins, and fiber.
Shiitakes, for example, contain lentinan, a nutrient that is thought to have anticancer properties. All mushrooms are good sources of vitamin D, thiamin, riboflavin, niacin, vitamin B6, pantothenic acid, phosphorus, potassium, copper and selenium.

Citrus fruits are loaded with vitamin C and, eaten whole, are a great source of fiber. Studies show that loading up on C-rich citrus at the first sign of illness may reduce a cold's duration by about a day. We also love adding a splash of lemon or lime juice to recipes.
Often tart and sometimes sweet citrus flavors add a punch of flavor without any added fat, calories, or cholesterol.

Garlic fights colds, battles cancer, and may even ward off urinary tract infections. A diet rich in garlic can help thanks to the bulb's natural antimicrobial properties.
To get the most health benefits out of this stinky bulb, let chopped or crushed garlic sit for 10 minutes before heating. This method helps it retain a third more of its cancer-fighting sulfur compounds than if it were cooked immediately.

Hot or mild, peppers are packed with vitamin C fiber for negligible calories. The heat in hot peppers signals the presence of capsaicin, a compound that, along with capsiate, can propel the body to scorch an extra 50 to 100 calories following a spicy meal.
Go for: Chilies as hot as you can stand. (But watch out! The hottest ones—habanero, Scotch bonnet, and Thai or Indian peppers—are too fiery for many people.)

When we talk about tea as a superfood, we mean black, green, white, or oolong (herb teas are infusions of other plants with different nutritional characteristics).
All “real” teas are high in polyphenols, an antioxidant that protects cells from the DNA damage that can cause cancer and other diseases. Tea may also lower LDL or bad cholesterol, ward off osteoporosis, boost your brain power, and keep you thin.
We’ll drink to that!
