Beets are one of those vegetables that many people have a complicated relationship with — they remember them from childhood as something earthy and strange, or they have only ever encountered them pickled and forgotten about them shortly after. That history of neglect turns out to be a significant nutritional mistake. Research from Cleveland Clinic, Columbia University Medical Center, Northwestern Medicine, and multiple peer-reviewed journals paints a consistent picture: beetroot is among the most nutrient-dense, physiologically active vegetables available, with documented benefits for the heart, brain, liver, muscles, gut, and inflammatory pathways throughout the body. Here is what doctors and registered dietitians say actually happens inside you when you start eating beets regularly.

Your Blood Pressure May Drop — Measurably
This is the most well-documented and clinically significant effect of regular beet consumption. Beets are naturally very high in dietary nitrates, which the body converts into nitric oxide — a compound that causes blood vessel walls to relax and widen, a process called vasodilation. The result is a measurable reduction in blood pressure that multiple studies have confirmed occurs within hours of consuming beetroot or beet juice. The effect is consistent enough that researchers at Columbia University’s medical center specifically flag cardiovascular health as one of beets’ most important contributions. For people with elevated blood pressure or early hypertension, adding beets to the diet is one of the most evidence-backed nutritional interventions available.
Your Athletic Performance Can Improve
The same nitric oxide mechanism that benefits blood pressure also improves exercise performance, which is why beetroot juice has become a well-established tool among endurance athletes. When nitric oxide increases blood flow and oxygen delivery to working muscles, the muscles can sustain effort longer before fatigue sets in. Research consistently shows that athletes who consume beet juice before training or competition experience improved stamina, reduced oxygen consumption during effort, and attenuated muscle soreness afterward. Northwestern Medicine exercise physiologists note that the combination of dietary nitrates from beetroot with regular physical activity also specifically supports brain blood flow during cognitive tasks — a benefit that compounds over time.
Your Brain Gets More Blood Flow
The frontal lobe — the region of the brain responsible for memory, decision-making, and higher cognitive function — is particularly dependent on adequate blood flow, and that blood flow naturally decreases with age as nitric oxide production in the body declines. Beets partially counter this decline. The dietary nitrates in beetroot increase blood flow specifically to the frontal lobe, and research suggests that consistent intake can help protect against the cognitive slowing, reduced processing speed, and memory impairment associated with aging. For people in their 40s, 50s, and beyond, this is one of the most compelling arguments for making beets a dietary staple rather than an occasional side dish.

Inflammation Decreases Throughout the Body
Beets contain a group of pigment compounds called betalains — responsible for their deep red color — that function as potent antioxidants and anti-inflammatory agents. Chronic low-grade inflammation is now understood to be an underlying driver of type 2 diabetes, cardiovascular disease, high blood pressure, asthma, obesity, and numerous other conditions that become more prevalent with age. Cleveland Clinic research has found that beet juice reduces inflammation markers throughout the body, and a 2014 study found that betalain supplementation from beetroot extract helped relieve joint pain associated with osteoarthritis. The anti-inflammatory properties of betalains are also being studied for their potential role in cancer prevention, with early research showing they may inhibit tumor cell proliferation and support programmed cell death in certain cancer types.
Your Liver Gets Protection
Beets are among a relatively small number of foods with documented liver-protective properties. They contain betaine — a compound derived from the same betalains that give beets their color — which helps reduce oxidative stress and inflammation in liver tissue. The liver is the body’s primary filtration and detoxification organ, and chronic oxidative stress in liver cells is a contributing factor to non-alcoholic fatty liver disease and other liver conditions. Regular beet consumption supports the liver’s ability to protect itself against this damage. Northwestern Medicine dietitians specifically call out beets as liver-friendly foods worth incorporating regularly for this reason.
Your Gut Health Improves
A single cup of cooked beets provides approximately 3.8 grams of dietary fiber — a meaningful contribution to the 25 to 38 grams per day recommended for adults. Beyond the direct benefits of fiber for digestive regularity and cholesterol management, beets specifically promote the growth of beneficial bacteria in the gut microbiome. A healthy and diverse gut microbiome is increasingly recognized as foundational to immune function, metabolic health, mood regulation, and systemic inflammation. Eating whole beets — rather than beet juice, which removes the fiber — delivers both the nitrate and betalain benefits alongside the gut health benefits of intact dietary fiber.
Your Folate Intake Gets a Significant Boost
Beets are one of the richest food sources of folate — vitamin B9 — which plays a central role in cell growth, DNA synthesis, and the repair of damage to blood vessel walls. Adequate folate intake is associated with reduced risk of cardiovascular disease, stroke, and certain cancers, and is essential for fetal neural tube development during early pregnancy. Many adults consume less folate than recommended, and beets represent one of the most practical and palatable ways to close that gap through food rather than supplementation.
One Thing That Will Surprise You: Beeturia
If you eat beets and then notice that your urine or stool has turned red or pink, do not panic. This is an entirely harmless phenomenon called beeturia, caused by a water-soluble pigment in beets called betanin that some people’s digestive systems do not fully metabolize. It passes through the body and colors urine temporarily. Beeturia affects roughly 10 to 14 percent of people and is not a sign of bleeding or any health problem. It is worth knowing about in advance simply because the first encounter with it, without context, can be genuinely alarming.
Who Should Be Careful
Beets are safe and beneficial for the vast majority of healthy adults, but a few groups should exercise some caution. People with a history of kidney stones should be aware that beets are relatively high in oxalates — compounds that can bind with calcium in the body and contribute to kidney stone formation in susceptible individuals. People taking blood pressure medications should note that the blood-pressure-lowering effect of dietary nitrates can enhance the effect of those medications, potentially causing blood pressure to drop lower than intended. Anyone managing gout should know that beets contain purines, which can be broken down into uric acid and may trigger flare-ups in sensitive individuals. For everyone else, the recommendation from registered dietitians at Northwestern Medicine and Cleveland Clinic is consistent: one cup of cooked beets or half a cup of beet juice daily is a practical and effective target.
How to Eat More of Them
Beets can be roasted, boiled, steamed, or eaten raw when shredded. They pair well with olive oil, goat cheese or feta, walnuts, and citrus in salads. Roasted beets with a drizzle of balsamic vinegar are a simple side dish that converts many beet skeptics. Beet juice can be added to smoothies where its earthy sweetness is balanced by fruit. Columbia University’s dietitians note that canned or frozen beets retain most of their nutritional value when fresh beets are not available or convenient — making this one of the more accessible vegetables to incorporate year-round. The one preparation note worth keeping in mind: betanin, the antioxidant pigment responsible for beets’ red color, is heat-sensitive and water-soluble, so prolonged boiling at high temperatures diminishes some of its potency. Roasting, steaming, or eating beets raw preserves more of this compound than aggressive boiling does.
