After years of being relegated to the recesses of the salad bar buffet next to the shredded cheese and buttered croutons, beets are enjoying their much-deserved place at the center stage of a healthy diet.
Blood pressure improves
Beets are rich in nitrates, which the body converts to nitric oxide—a compound that relaxes and dilates blood vessels, turning them into superhighways for your nutrient- and oxygen-rich blood. That means better circulation, and possibly lower blood pressure. A very small study from 2012 found that 13 men who drank just one glass of beet juice temporarily lowered their systolic blood pressure by an average of 4 to 5 points.
Your heart disease risk may drop
Beets don’t just have an potentially positive impact on your blood pressure. They are also rich in a plant alkaloid called betaine, as well as the B-vitamin folate, which together deliver a one-two punch for lowering blood levels of homocysteine, which in high levels increases your risk for artery damage and heart disease.
You may improve your stamina
When elite athletes pee in a cup for a drug test, the color might be crimson. Why? Because lots of athletes eat beets—they know research has suggested that nitrates boost endurance performance—and beets contain pigments that turn urine pink. In one study, cyclists who drank beet juice could pedal hard 15% longer in a time trial to exhaustion.
Your brain may work better
Nitric oxide relaxes and dilates your blood vessels, which in turn increases blood flow to the brain—which could bring on better brain function. That’s particularly important as we age, as research finds that our capacity to generate nitric oxide diminishes as we get older, along with our brain’s energy metabolism and neuron activity. So give your brain a boost with beets.
Your liver will be lighter
Your liver does the heavy work of cleaning your blood and “detoxing” your body. You can lighten its load with a daily serving of beets. Research shows that betaine, an amino acid found in beets (as well as spinach and quinoa) can help prevent and reduce the accumulation of fat in the liver. Animal studies show that rats given beet juice have higher levels of detoxifying enzymes in their bloodstream.
You may be better at fighting chronic diseases
Beets are also rich in betalains, a class of potent antioxidants and anti-inflammatories that battle free radical- and inflammation-related chronic diseases like heart disease, obesity, and possibly cancer.
You become regular
“One way to beat irregularity and constipation is by eating fiber-rich foods like beets,” says Leslie Bonci, RD, sports nutritionist at Pittsburgh-based company Active Eating Advice. One cup of beets delivers about 4 grams of dietary fiber, particularly insoluble fiber, which helps reduce the risk of constipation, hemorrhoids, and diverticulitis.
