Did you know that beet juice is part of the magic potion recipe from which Asterix draws his superhuman strength? Believe it or not, several recent studies have demonstrated that this juice does indeed improve physical performance!
Beet’s magic ingredient
Every organ of your body requires oxygen in order to function. When you practice a sport, your muscles become active and produce more energy. Therefore, they need a greater quantity of oxygen. That’s where nitrates, one of the elements contained in beet juice, come into play.
Nitrates are naturally occurring substances found in food, water, and air. The greatest food sources for nitrates are vegetables, particularly beet, celery, lettuce, radishes, and spinach.
Nitrates found in beet juice reduce the oxygen needs of muscles. Each breath is therefore more efficient, and since the body doesn’t get as tired it can tolerate intense effort for a longer period of time. In addition, nitrates promote blood vessels dilation, which increases blood and oxygen supply towards muscles.
Beet juice, a realistic strategy?
Although we have proven the effectiveness of drinking beet juice to improve sport performances, the long-term consequences of this practice are still unknown. On the other hand, studies have demonstrated that beet juice might protect us against some forms of cancer, such as prostate, breast, liver, and lung cancer. This protective effect is attributed to its high betaine content, an antioxidant.
Moreover, the World Health Organization recommends that you consume 200 to 400 mg of nitrates a day, which corresponds to 2 or 3 beets. A nutrition rich in vegetables can also provide you with the nitrates required for you to be at your peak performance!
