What Are the Benefits of Eating Beetroot? What the Research Actually Shows

Beetroot doesn’t have the best reputation. People usually either love it or avoid it because of its strong earthy taste. That’s a shame, since behind that bold flavor is one of the most well-studied vegetables you can buy.

So, what are the real benefits of eating beetroot? Instead of vague claims like “boosts everything,” let’s look at the specific, proven effects on blood pressure and exercise performance that have been tested in many clinical trials.

This guide explains what the research really supports, what it doesn’t, and how you can add beetroot to your diet without making every meal turn pink.

What are the Benefits of Eating Beetroot in the Body, nutritionally?

Before getting into the headline-grabbing effects, it helps to know what’s actually in a serving of beetroot.

A cup of cooked beetroot provides roughly 74 calories, about 3.4 grams of fiber, close to 37% of your daily folate needs, and meaningful amounts of potassium and manganese, according to USDA nutrient data.

That’s a genuinely solid nutritional package for the calorie cost. But the compound getting most of the scientific attention isn’t a vitamin or mineral at all — it’s dietary nitrate, a naturally occurring compound that beetroot contains in unusually high concentrations compared to most other vegetables. That nitrate is responsible for nearly everything beetroot is actually known for in clinical research.

What Are the Benefits of Beetroot for Blood Pressure?

This is the most thoroughly documented effect in beetroot research, and the evidence supporting it is strong.

Beetroot is high in nitrates, which the body turns into nitric oxide. This process helps relax and widen blood vessels. Several independent meta-analyses of randomized controlled trials have shown that this leads to a real, measurable drop in systolic blood pressure.

A 2024 syA 2024 systematic review and meta-analysis focusing on adults with high blood pressure found that beetroot juice lowered clinical systolic blood pressure by an average of 5.31 mmHg. Daily nitrate intake between 200 and 800 mg did not lead the body to build up a tolerance over time. This result is similar to earlier findings. For example, a 2013 meta-analysis of 16 trials with 254 participants found a 4.4 mmHg drop in systolic blood pressure from nitrate and beetroot juice supplements. Across studies, the effect is stronger for systolic blood pressure than for diastolic, and it usually does not last much beyond the day of intake. This means that taking beetroot daily is more effective than having a large dose only once in a while.

What Are the Benefits of Beetroot for Exercise and Stamina?

This is one area where beetroot’s reputation as an “energy” food is backed by real science. However, the way it works is more specific than most articles explain.

The nitrates in beetroot help your muscles use less oxygen to do the same amount of work. This is a real improvement in efficiency, not just a general energy boost. A key 2009 study by Bailey and colleagues found that beetroot juice lowered oxygen use by about 3 to 5 percent during steady exercise. More recent studies show that this effect can be even greater in trained athletes, with some research reporting endurance improvements of 2 to 16 percent, depending on the sport and the athlete’s training level. This is why beetroot juice is so common in endurance athlete nutrition plans. It is one of the few “natural” supplements with a proven performance benefit that has been confirmed by several independent research teams, not just a single study.y.

Does Beetroot Help with Cortisol or Stress?

Many people wonder about this, and it’s important to give an honest answer instead of just a comforting one.

There isn’t strong clinical evidence that eating beetroot lowers cortisol levels. Most research on beetroot focuses on blood pressure and how the body uses oxygen during exercise. These are different from the ways the body controls cortisol, which is the stress hormone.

It’s easy to see why people get confused. Nitric oxide from beetroot does help relax blood vessels, and some health articles link this to feeling calm. However, this works differently from how the body actually controls cortisol through the HPA axis. If you want to manage stress and cortisol, things like good sleep, regular exercise, and stress-management habits have much stronger research support than any single food. Beetroot still has other proven benefits, but current evidence does not show it lowers cortisol.

What Are the Benefits of Beetroot for Brain Function?

The research in this area is valid, but it is not as far along as the evidence for blood pressure. It is important to keep this in mind.

Since nitric oxide helps blood flow throughout the body, some studies have looked at whether the nitrates in beetroot might also help blood flow to the brain. Early research suggests there could be benefits for certain brain areas in older adults.

This is an interesting area that researchers are still studying, but it is not as well established as the findings on blood pressure and exercise. If you hear that beetroot boosts brainpower, remember that this idea is still being tested and is not yet proven like its effects on the heart.

What Are the Benefits of Beetroot for Digestion?

Fiber quietly and reliably supports digestion here, just as it does in most vegetables.

The fiber in beetroot helps keep digestion regular and nourishes good gut bacteria. This supports overall digestive health when included in a varied, fiber-rich diet.

One cup of beetroot has about 3.4 grams of fiber. While it is not the highest-fiber vegetable, it still makes a valuable contribution to your diet, especially when combined with other fiber sources like lentils and legumes mentioned in our guide to low-fat protein sources for vegetarians.

Is Beetroot Good for Weight Management?

Like most low-calorie, high-fiber vegetables, beetroot works in a simple and straightforward way, not because of any special metabolic effect.

A cooked cup of beetroot has about 74 calories and a good amount of fiber. It makes meals more filling and can support a calorie-conscious diet without strict limits.

The main benefit, as with most vegetables like this, comes from using beetroot to add bulk and nutrients to meals instead of relying on refined carbs. It is a helpful part of a weight-management diet, but not a complete solution on its own.

Is It Safe to Eat Beetroot Every Day?

For most people, yes, but there are two specific things worth knowing that go beyond the usual warnings.

Beetroot can sometimes cause a harmless red or pink color in urine or stool, which is called beeturia. Because beetroot contains natural oxalates, people who are prone to kidney stones may want to eat it in moderation.

Beeturia is completely harmless. It happens because your gut and kidneys process betalains, the pigments that give beetroot its color, in a certain way. It is not a sign of any health problem. The issue with oxalates mostly affects a smaller group of people. Those who have had calcium-oxalate kidney stones are sometimes told by their doctors to limit high-oxalate vegetables, including beetroot, as part of their overall diet plan.

How Do You Add Beetroot to Your Diet?

You don’t have to drink beetroot juice to get most of the benefits. Eating whole beetroot works as well and gives you fiber that juice does not.

You can include beetroot in your diet by roasting, steaming, grating it raw into salads, or juicing it. Juice gives you a higher dose of nitrates, while whole beetroot provides more fiber.

Roasting beetroot brings out its natural sweetness and makes it a great side dish with a protein.

Grating beetroot raw adds crunch and color to salads, and you don’t need to cook it.

Juicing beetroot is the method used in most of the clinical research mentioned above. Studies usually use daily doses of 70 to 250 ml for noticeable effects.

Blending beetroot into smoothies is an easy way to add it to your diet, especially if you don’t like the taste on its own.

If you want the blood-pressure or exercise benefits described above, juice is closer to what researchers studied. For general nutrition and fiber, whole cooked or raw beetroot is a better choice for daily use.

What Does the Research Say, overall?

Here’s a summary of all the evidence mentioned above, gathered in one place:

• A 2024 meta-analysis of adults with high blood pressure found that beetroot juice lowered systolic blood pressure by an average of 5.31 mmHg, and this effect did not fade over time.
• A 2013 meta-analysis that included 16 trials and 254 participants found that taking nitrate or beetroot juice supplements lowered systolic blood pressure by 4.4 mmHg.
• A key study from 2009 found that beetroot juice reduced oxygen use by 3 to 5 percent during steady, moderate exercise, making exercise more efficient.
• Recent studies have shown that trained people who drink beetroot juice can improve their endurance by 2 to 16 percent, depending on their sport and training level.
• According to USDA data, one cup of cooked beetroot has about 74 calories, 3.4 grams of fiber, and roughly 37 percent of your daily folate needs.
• There is no strong clinical evidence that eating beetroot lowers cortisol levels. Its proven effects are on blood pressure and exercise performance, which involve different biological processes than stress hormone regulation.

Beetroot is a well-studied vegetable, with strong and consistent evidence for its benefits on blood pressure and exercise performance, and clear acknowledgment of where research is still lacking.

Final Thoughts: So, What Are the Benefits of Eating Beetroot?

The real benefits of eating beetroot stand up to close examination. Multiple independent meta-analyses show it can meaningfully lower blood pressure, and its positive effect on exercise efficiency is well established in sports nutrition research. These facts make a strong, honest case for beetroot, without needing to rely on unsupported claims about cortisol or brain-boosting effects.

Here are the key points to remember:

• Beetroot juice is best supported by evidence for lowering systolic blood pressure, especially in adults with high blood pressure.
• The benefit for exercise performance is real and consistent, particularly for endurance activities.
• There is no direct evidence yet to support claims that beetroot lowers cortisol, so consider that a plausible-sounding myth.
• Whole beetroot provides more fiber, while juice is closer to the amounts used in clinical research.
• Most people can safely eat beetroot every day, though those who are prone to kidney stones should be cautious.

Pair a beetroot habit with the rest of a solid routine — regular movement and consistent morning habits included — and you’ve got a genuinely evidence-backed vegetable working alongside genuinely evidence-backed habits, rather than either one trying to do all the work alone.
