The value of beets
One cup of raw beets contains phosphorus, sodium, magnesium, calcium, iron, and potassium as well as vitamin A, niacin, folic acid, and biotin. When these nutrients are captured in a juicing process, they remain in a form that is much easier to assimilate than synthetic nutrients. The iron in beet juice, in particular, is noted for being more easily assimilated than other forms of iron supplements.
Potassium, in particular, is essential for all cellular functions. Along with sodium, it regulates water bal- ance and acidity-alkalinity balance in the blood and tissues. It is often depleted with aging, in degenerative disorders, and with a highly refined diet that is high in sugar.
