The beet juice is considered as one of the best vegetable juice. It is a rich source of natural sugar. It contains sodium, potassium, phosphorus, calcium, sulfur, chlorine, iodine, iron, copper, vitamin B1, B2, C and P. This juice is rich in easily digestible carbohydrates, but the calorie content is low. The protein factors or amino acids are good in both quality and quantity. Never drink beet juice by itself. Beet juice should always be mixed with other vegetables and/or apple juice. Pure beet juice (from the bulb or greens) can temporarily paralyze your vocal chords, make you break out in hives, increase your heart rate, cause chills or a fever.
