The next time you head to the gym, you might want to bring
along a bottle of beet juice: Drinking a glass of the stuff each day may make
your workouts easier, according to new research from University of California
at Davis and Korea's Kyung Hee University.
Past research showed that drinking beet juice just before
working out can increase your tolerance for high-intensity exercise, most
likely due to the veggie's high concentration of nitrates, but researchers were
curious to see how regularly sipping beet juice can affect your body long-term.
In the study, 14 men in their 20s drank 70 ml of
concentrated beet juice (with the nitrate equivalent of 300 ml or regular beet
juice) each morning for about 2 weeks. Half of the study participants drank the
regular beet juice you'd find at the grocery store; the other half guzzled
nitrate-depleted beet juice. When the guys were put through high-intensity
cycling workouts, the ones who'd had the nitrate-rich beet juice had lower
blood pressure.
"Because their hearts weren't working as hard to pump
blood into circulation, they could push themselves at the same intensity for a
longer period of time," says study coauthor Charles Stebbins, PhD. That
same group of participants also had better blood flow and oxygen delivery to
their muscles, he says.
Since the only difference between the two groups was the
amount of nitrates they were drinking each day, researchers are pretty
confident that's what's at play. And just because the study was done on a bunch
of guys, don't think that women won't get the same benefits: Past research has
confirmed that ladies who drink beet juice will also have lower blood pressure
during exercise, Stebbins says.
If you're not a big fan of the bright red stuff, try
incorporating it into your next smoothie—it'll definitely help you push through
the exhaustion that normally hits halfway through your spin class. (Try this
Cran-Beet Crusher smoothie recipe.) Or you can get nitrates through other
healthy additions to your diet: A 3.5-ounce serving of celery, chervil, cress,
arugula, spinach, or, of course, beets will give you about 250 mg—the same as
you'd get from a glass of beet juice.
