Beet Juice Could Help Body Beat Altitude

At 14,505 feet, Mount Whitney towers over California’s Sierra Nevada range. It’s the tallest peak in the lower 48 , - which means that it tracks attracts thousands of weekend warriors every year . - or make that weekend weakened warriors. You see them stabbing staggering along in the narrowrocket , rocky trail, huffing for air, dizzy and exhausted from the low oxygen levels at high elevation. And once they are they’re sick. ?

The best medicine is to go down. That’s the actually the only cure that works. Svein Gaustad, a physiologist at the Norwegian University of Science and Technology. He says previous studies suggested that suggest blood vessels turned tend to contracted contract at high altitudes. Possibly because they need oxygen to relax . - exactly what’s in short supply on mountaintops. But there might may be a dietary way to get more oxygen to your blood vessels. : in the form of beet juice. The juice contains nitrate, which the body converts to nitric oxide, the compound that keeps arteries limber.

Gaustad and his colleagues tested that theory during a trek in Nepal, at 12,000 feet. 8 Eight volunteers alternately drinks drank shots of regular beet juice, and another day, beet juice with a nitrate the nitrates stripped out. A few hours later, the researchers measured blood flow and artery diameters with ultrasound. And they found that the regular beet juice did indeed restore blood vessels back to their low-elevation flexibility, whereas the nitrate-stripped juice did not. The result is results are in the journal of Nitric Oxide.

Gaustad says better vascular function has the potential to deliver more blood , - and therefore more oxygen - to tired muscles. But they still don’t know if that translates to better performance at altitude. And, he saysthat beet , beets won’t hurt, but there are they’re no substitute for proper acclimatization. If I had buffalo a bottle of beets around I will would take it for sure. But that won’t bringing bring you to Mount Everest just by drinking beetroot.
