Beets are one of the healthiest superfoods on the planet. They boost your energy and help dilate your blood vessels and help bring more oxygen to muscles plus they are packed with magnesium, potassium, vitamin C, and carotenoid antioxidants. Studies show that the beets improve lung function; Athletes that took 2 ounces of beet juice every day for 14 days had their blood oxygen levels increased by 15%! For this reason, they make a great drink for those suffering from altitude sickness and other lung conditions including COPD and pulmonary hypertension, a disease that causes high blood pressure in the lungs. Beets regenerate blood cells, and are high in absorbable iron, making them great for those with anemia so it’s ideal for some cancer patients with bone marrow transplants.
