Nutritional value of beets - Part 10: Magnesium

Beet greens

Beet greens - raw: Magnesium
Measure: 38g (1 cup)
Calories: 8

The RDA* of magnesium is 350 mg for adult males and 300 mg for adult females, of which, one cup of raw beet tops provides 26.6 mg or 7%.

Magnesium increases the solution of calcium in urine and, thus, plays an essential role in preventing the formation of kidney stones.

Magnesium enables contractions of the heart. In its overall effects on muscles, it performs much the same functions as does potassium. 
Indeed, the symptoms of magnesium deficiency are the same as those of potassium deficiency. 

Your body requires an adequate supply of calcium in order to use magnesium, and calcium requires an adequate supply of Vitamin D in order to be absorbed into bones and muscles.

* RDA has been made obsolete by the USDA and so, as of March 2011, when I do mention it, it shall only be as a quaint matter of historical interest. RDA has been replaced by three other measures which are (a) unrelated to RDA and (b) meaningless for all practical purposes at this time. This will remain the case until such time as the new measures are sufficiently and comprehensively developed to the point of serving a meaningful purpose.

For a broad overview of one of the new, incomplete standard measures, check out Dietary Reference Intake .
