Beetroot’s high nitrate content and other properties may help circulation, lower blood pressure, protect arteries from stiffness, reduce damage after blood-flow stress, and support people already at cardiovascular risk—when used alongside a balanced diet and prescribed treatments.
Beetroot is rich in dietary nitrates that convert to nitric oxide, which relaxes and dilates blood vessels and can improve circulation and lower blood pressure.
Small clinical studies link beetroot juice or beetroot consumption to more elastic arteries and reduced damage after ischemia-reperfusion injuries, but results are not exclusive to beetroot.
Beetroot can support pathways implicated in hypertension, diabetes, inflammation, and high homocysteine, but it should complement—not replace—medication and a balanced diet.
Context and practical point of view
Foundation recommends at least five portions of fruit and vegetables daily (about two servings of fruit and three of vegetables) to lower the risk of heart and circulatory disease and potentially live longer. After meeting that baseline, choosing specific vegetables can add measurable benefits. Cardiologist Dr Francesco Lo Monaco highlights beetroot as a useful, evidence-backed option for vascular health.
Beetroot contains high levels of dietary nitrates. The body converts nitrates into nitric oxide, a molecule that helps blood vessels relax and dilate. That physiological effect can improve circulation, reduce blood pressure, and support a healthier endothelium (the inner lining of blood vessels). Some small studies have associated beetroot juice with lower blood pressure.
Support for people already at cardiovascular risk
Dr Lo Monaco notes beetroot acts on multiple pathways affected by conditions such as hypertension, diabetes, inflammation, and elevated homocysteine. One study among people with type 2 diabetes found that consuming 100 g of raw beetroot daily for eight weeks was associated with improved metabolic markers and cognition. These findings point to potential benefits for at-risk groups, while reminding readers that dietary changes are a complement to medical care.
Beetroot can be included as part of a balanced diet to bolster vascular repair and performance. It is not a substitute for prescribed medications. The cardiologist recommends small, manageable changes to diet to improve health over time rather than relying on a single "superfood." If you have high blood pressure or a cardiovascular condition and are considering high-nitrate foods or supplements, discuss this with your clinician before making major changes.
Beetroot is a practical, evidence-based choice among nitrate-rich foods that can help blood vessels relax, lower blood pressure in some studies, maintain arterial elasticity, and reduce some forms of heart damage. Use it alongside a varied diet and prescribed treatments rather than as a replacement.

Think back to conversations around nutrition when you were younger. You probably heard a lot of advice beginning with “Finish your vegetables.” And if you’ve been talking about broccolini more lately, you’re not alone. FullTilt Marketing reports that social discussions around the veggie are up 25 percent year over year
Potatoes have had a rough go of things. Most recently, the high-protein, anti-carbohydrate people have spread the message that potatoes are full of fattening carbs. Back in the anti-fat ’80s, we were told that mashed or fried potatoes were too rich, guaranteed to pack on the pounds. Before that, there were the anti-nig
