Proven Health Benefits of Beets and Fermented Beets (Science-Based)
Beets (beetroots) are nutrient-rich root vegetables known for their deep red-purple color and high levels of dietary nitrates, antioxidants, fiber, and plant compounds. Fermented beets add another dimension by introducing beneficial microorganisms and organic acids, although research on fermented beets specifically is still developing.
Here are the science-supported benefits of beets and what we know about fermented versions.
1. May Help Lower Blood Pressure
One of the best-studied benefits of beets comes from their natural nitrates.
The body converts nitrates into nitric oxide, a molecule that helps blood vessels relax and widen. This may improve blood flow and contribute to modest reductions in blood pressure, especially in people with elevated blood pressure.
Helpful forms include:
- Beet juice
- Cooked beets
- Whole beets
The effect is often strongest a few hours after consumption and may vary between individuals.
2. Supports Exercise Performance and Endurance
Beets are popular among athletes because dietary nitrates may improve how efficiently muscles use oxygen.
Potential benefits:
- Improved endurance
- Reduced oxygen cost during exercise
- Better exercise capacity in some people
Studies have shown benefits particularly in endurance activities such as cycling and running.
3. Provides Powerful Antioxidants
Beets contain compounds such as:
- Betalains (the pigments responsible for their color)
- Polyphenols
- Vitamin C and other antioxidants
These compounds help protect cells from oxidative stress, which is involved in aging and many chronic conditions.
4. Supports Heart and Blood Vessel Health
By supporting nitric oxide production and providing fiber, beets may contribute to cardiovascular health.
Possible benefits include:
- Supporting healthy blood vessel function
- Helping maintain healthy cholesterol levels as part of a high-fiber diet
- Supporting overall heart health
Beets are not a replacement for prescribed heart or blood pressure treatments, but they can be part of a heart-healthy eating pattern.
5. Promotes Digestive Health
Beets provide dietary fiber, which helps:
- Support regular bowel movements
- Feed beneficial gut bacteria
- Improve digestive health
Fiber intake is associated with a lower risk of several chronic diseases when part of a balanced diet.
6. May Support Brain Health
Because nitric oxide helps regulate blood flow, researchers have studied whether nitrate-rich foods like beets may support brain circulation.
Some studies suggest beets may help improve blood flow in areas of the brain involved in functions such as attention and decision-making, though more research is needed
