Beets Make Your Workout Sessions Longer
If you want to push yourself harder during exercise, eat beets beforehand. During a 2012 study, researchers observed people who ate beets 15 minutes before a workout. Beets lowered the amount of oxygen that the body needed to work out. As a result, participants lifted heavier and pushed themselves harder, says the study in the Journal of the Academy of Nutrition and Dietetics.
Beets can pull this off through their dietary nitrates, which convert nitric oxygen in the body. This improves blood flow and VO2 max, a fancy term for endurance. According to Registered Dietitian Heather Steele, juiced beets are more effective than whole beets.
