Sweet potatoes are of great value as an energy food.
The sweet potato, especially the coloured varieties, contains vitamins. The yellow ones are the richest in vitamins.
The tubers contain much starch, and this can be extracted from the tubers in factories.
The sweet potato can also be used for making alcohol. The leaves of the plant are used for food, both for people and animals.
