This vegetable is pretty much synonymous with good health—and for good reason: it’s a great source of beta carotene, vitamin C and phytochemicals, called isothiocyanates, that amp up the body’s detoxifying enzymes. Kale is also a great vegetable to have on hand when you’re trying to cut calories. Why? Kale is awesome in soups and, according to several research studies, soups tend to be über-satisfying, which means you can feel full on fewer calories.
