It might not make your mouth water to look at it but kale is a major “super food.”

One of the worlds healthiest foods, kale is both delicious and nutritious.

Why has kale gotten an edge on all the other dark leafy greens? Tamara Duker Freuman, a dietician and nutritionist with a fantastic blog called What I’m Eating Now, says kale scores a perfect 1,000 on the Aggregate Nutrient Density Index, a food-rating system that measures nutrients per calorie. “While I view the term ‘superfood’ with more than a healthy dose of skepticism (it’s more of a marketing term than a nutrition term), I would be hard-pressed to come up with a food more deserving of the title,” Duker Freuman says of kale.

Nutritionally, kale has Vitamins K, A and C, and calcium and iron going for it. The distinctive crunch of baked or fried kale is also likely to appeal to people of all ages, says Duker Freuman.
