Concerning nutrition, root vegetables contain reasonable amounts of vitamins and minerals, such as potassium, calcium, vitamin C and vitamin A. Many root vegetables are low in calories, so they are a good option for weight loss. They are also high in fibre, thus contributing to good digestion. A word of caution; root vegetables can be high in carbohydrates. With your root vegetables, take a root-to-stem approach and consider using the often thrown-away parts.
