We’ve all heard that the darker the green, the healthier it is (primarily because of an increased density of phytochemicals and vitamins), but despite the hype, kale is not the only ‘supergreen’ that falls into this delicious dark green category. Spinach, swiss chard and watercress contain as many vitamins and minerals as kale, with even a slightly lower carbohydrate and calorie count. Spinach contains the highest amounts of folate and iron (which contribute to red blood cell production) of all leafy greens. Swiss chard contains 400% of the daily recommended intake of vitamin K and watercress contains as much calcium by weight as milk. Most dark leafy greens are healthy, so don’t limit yourself to a single type. All you have to do is start exploring!
