Clemson University researchers have found that kale may help billions of people worldwide overcome micronutrient malnutrition. People could eat kale to help supply their bodies with the micronutrients potassium, calcium, magnesium, iron, and zinc, as well as prebiotic carbohydrates and dietary fiber. Researchers found that one 100-gram serving of kale provides 10% of the recommended daily allowance for several micronutrients. The kale types used in this study included curly varieties Darkibor, Dwarf Green Curled Afro, Pentlang Brig, Red Russian, Redbor, Reflex, Ripbor, Scarlet, Star and Stripes, Starbor, Vates, Winterbor, Blue Ridge, Blue Knight and Maribor. Portuguese varieties studied were Beira and Dauro. Dinosaur Black Magic varieties in the study were Bonanza, Italian Kale and Lacinato. The ornamental variety studied was Fizz, and Mustard varieties studied were Frizzy Joe and Frizzy Lizzy. The Clemson study was funded by a specialty crop block grant from the S.C. Department of Agriculture.
