Sweet potatoes are packed with beta-carotene; fiber; vitamins A, several Bs, and C; and minerals like iron, manganese, magnesium, and potassium. They also are a gut friendly vegetable since they are a good source of resistant starch that helps feed good gut bacteria. Air-fried cubes use a lot less oil, and studies show that air-fried tubers are almost acrylamide-free (acrylamide is a toxin produced in potatoes and sweet potatoes when cooked at very high temperatures). Black sesame seeds are high in several B vitamins and contain large amounts of calcium, magnesium, manganese, phosphorous, iron, and zinc. Eating sesame seeds appears to help lower blood pressure and reduce oxidative stress and damage to cells.
