Roasted Yams with Rosemary

Yams, which in the United States are actually sweet potatoes, are an excellent source of beta-carotene, vitamin C, and Vitamin B6. Beta-carotene is a powerful antioxidant, which works in the body to help eliminate free radicals. Vitamin B6 is needed to convert homocysteine into the beneficial amino acid cysteine. High homocysteine levels are associated with an increased risk of heart attack and stroke. I like to serve this dish with baked wild salmon and sautéed kale for an easy weeknight meal.
