Vitamins
A single cup of cooked ube yams gives you 18 to 24 percent of your daily vitamin A requirements in addition to providing you with 18 to 22 percent of your daily vitamin C. Both of these important vitamins have antioxidant activities that can help your body age more gracefully and prevent diseases.

Each cup of ube yams contains almost 20 percent of your daily needs for potassium, an important nutrient that can help control and maintain your blood pressure within the normal range.
