Arugula

Calories: 4 per cup
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.

Asparagus

Calories: 27 per cup
Asparagus is traditionally known as a detoxifying food, because it contains high levels of an amino acid that acts 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).

Broth

Calories: 10 per cup
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.

Cabbage

Calories: 22 per cup
Crunchy, sweet, and affordable! How can a food that is so humble, with so few calories, be so incredibly good for you? Cabbage packs vitamins, minerals, fibers, and several phytonutrients thought to prevent cancer. Glucosinolate is a metabolic detoxifier and sulphoraphane is a powerful anti-carcinogenic.

Turnips

Calories: 36 per cup
The potatoes skinnier cousin, turnips are a great source of fiber and vitamin C, and have a low glycemic load. We love them diced and tossed into soups or stews, or sliced raw and used in crudite (they taste surprisingly mild and crunchy!).

Zucchini

Calories: 20 per cup
This miracle squash is the ultimate high volume food, meaning you can fill up on very few calories. It’s easy to grow, especially in the summer, packs lots of vitamin A, and is so simple to prepare raw or cook with you may want to eat it all year!

Kale

Calories: 5 per cup
Kale is possibly the healthiest superfood around, packing a widevariety of phytonutrients that may prevent cancer, including breast cancer. (Scientsits theorize that the phytonutrients in kale trigger the liver to produce enzymes that neutralize potentially cancer-causing substances.)
