The secret to the healing powers of the humble beetroot?

Turns out, it’s an incredibly concentrated source of dietary nitrate. If you’ve never heard of “dietary nitrate,” you’re far from alone.

The story of dietary nitrate begins with nitric oxide, not to be confused with nitrous oxide—aka laughing gas. The journal Science once declared nitric oxide to be the “molecule of the year,” and three scientists earned the Nobel Prize in Physiology or Medicine for their research on this substance. That’s an impressive pedigree.

Nitric oxide helps the body’s cells talk with each other, and one of its functions is to tell the endothelial cells that line blood vessels to dilate or relax. Because of this property, nitric oxide plays a key role in maintaining normal blood pressure.

Nitric oxide’s nutritional precursors include the amino acid L-arginine, but dietary nitrate is also an often overlooked and excellent precursor. Through a series of steps, the body converts nitrate to nitric oxide.

Many fruits and vegetables are good sources of nitrate, and there are significant amounts of nitrate in celery, lettuce, arugula, and spinach. But the hands-down richest source is beetroot and, in particular, beetroot juice and concentrate.
