One cup of cooked beets per day (roughly two medium beets) is a good target for most people, according to Northwestern Medicine. If you prefer juice, about half a cup covers similar ground. That said, the “right” amount depends on why you’re eating them, since the research behind blood pressure, exercise performance, and general nutrition each points to slightly different quantities.
What One Cup of Beets Actually Gives You
A medium beet weighs around 80 to 100 grams raw, so two medium beets gets you close to that one-cup-cooked recommendation. Per 100 grams, raw beets contain about 5.1 grams of sugar, a moderate amount of fiber, and roughly 495 milligrams of naturally occurring nitrates. Those nitrates are the star compound: your body converts them into nitric oxide, which relaxes blood vessels and improves blood flow.
Beets also contain pigments called betalains, which function as antioxidants. In lab studies on human liver cells, these pigments activated a protective pathway that boosted the activity of detoxifying enzymes by 18 to 44 percent. While lab results don’t translate directly to what happens in your body after eating a beet, they help explain why beets consistently show up in research on liver health and inflammation.
For Blood Pressure: About 250 mL of Juice Daily
The strongest evidence for a specific daily amount comes from blood pressure research. A study highlighted by the British Heart Foundation found that people with high blood pressure who drank 250 milliliters (roughly one cup) of beetroot juice daily brought their readings back into the normal range by the end of the trial. That’s the equivalent of about two to three whole beets juiced, depending on their size.
If you’re eating whole beets instead of juicing them, you’ll still get nitrates, but the concentration is lower per serving because the fiber and pulp take up volume. Sticking with two medium beets daily is a reasonable approximation. The key is consistency: blood pressure benefits come from regular daily intake, not a one-time serving.
For Exercise Performance: Timing Matters More
Athletes and gym-goers searching for a pre-workout edge need a more precise dose. Research from the National Strength and Conditioning Association identifies 8 millimoles of nitrate as the optimal amount for improving endurance. To put that in food terms, you’d need a concentrated beet juice shot (the kind sold in 70 mL bottles at health food stores) or a large glass of fresh-pressed beet juice.
Getting that same amount from whole beets alone would require eating a substantial quantity in one sitting, which is one reason concentrated shots are popular with athletes. Timing also plays a role. Studies show the performance benefits peak when you consume beet juice 2 to 2.5 hours before exercise, giving your body enough time to convert nitrates into nitric oxide.
Sugar and Glycemic Considerations
Beets taste sweet for a root vegetable, and their boiled glycemic index of 64 puts them in the medium range. For most people eating one to two beets a day, this isn’t a concern because the total sugar load stays modest, around 10 grams per cup of cooked beets. That’s less sugar than a medium apple.
If you’re managing blood sugar carefully, whole beets are a better choice than juice. Juicing removes the fiber that slows sugar absorption, so the same amount of beet in liquid form hits your bloodstream faster. Pairing beets with a fat or protein source (roasted beets in a salad with goat cheese, for example) also blunts the glycemic response.
Who Should Eat Fewer Beets
Beets are high in oxalates, compounds that bind with calcium and can contribute to kidney stones. Beetroot juice contains 60 to 70 milligrams of oxalate per 100 milliliters, and drinking even 500 milliliters a day adds meaningfully to your total oxalate load. If you’ve had calcium oxalate kidney stones, limiting beet intake or choosing lower-oxalate vegetables is worth discussing with your care team.
People on blood-thinning medications or those with very low blood pressure should also approach large daily servings cautiously, since the nitrate-driven drop in blood pressure can compound other effects.
The Red Urine Question
If your urine turns pink or red after eating beets, you’re not bleeding. This harmless phenomenon, called beeturia, affects 10 to 14 percent of the population. It’s related to how your body processes the red pigments in beets and has been linked to factors like stomach acidity and iron absorption. It’s completely benign, but it surprises people enough that it’s worth knowing about before you start eating beets daily.
Practical Starting Points
- General health: 1 cup cooked beets (about 2 medium beets) or half a cup of juice daily.
- Blood pressure support: 250 mL (1 cup) of beetroot juice daily, consumed consistently.
- Pre-workout performance: A concentrated 70 mL beet shot containing 8 mmol nitrate, taken 2 to 2.5 hours before exercise.
If you’re new to eating beets regularly, start with a smaller portion and increase over a few days. Some people experience mild digestive changes as their gut adjusts to the fiber and pigments. Roasting, steaming, or adding raw beets to smoothies all preserve the nitrate content, so preparation method comes down to what you’ll actually keep eating.
