A beet with juice.

I remembered it being red, cut in chunks and with a liquid that stained. Plus, Mom always served it on Sundays.
Beets are a root veggie with edible leafy green tops, and firm, smooth skins. Loaded with potassium and some fiber.
Now, the WSJ is reporting from a study that, "daily consumption of beetroot for four weeks, significantly lowered blood pressure in hypertensive patients compared with a placebo juice."

Beetroot juice, or beet juice, is made from the root of the beet plant beta vulgaris.
Inorganic nitrate, a compound found in beets, enters the circulation system where some are converted to nitric oxide ... a helpful blood-vessel regulator.

Over the study period, systolic blood pressure, the top blood pressure number, decreased from 7.7 to 8.1 points in people that received dietary nitrate. The bottom number, diastolic blood pressure, decreased 2.4 to 5.2 points.

What are the long term effects of consuming too much of a good thing? No one knows. Be on the look out for discoloration of urine and stool!
