Taro has more nutritional value than potatoes and most other tubers and root vegetables. Taro is low in calories, full of fiber, and has B and C vitamins, free radical-fighting antioxidants, and minerals like copper, zinc, manganese, potassium, phosphorus, calcium, and iron. That means taro is a healthy choice for your heart, thyroid, blood, energy, metabolism, weight, digestion, vision, circulation, immune system, blood sugar, and blood pressure, and they might even reduce cancer risk.
