When not to take beetroot? Important health considerations

December 16, 2025 •

2 min read

According to a study published in Clinical Nutrition Research, boiled beetroot can still contain over 50 mg of oxalates per 100 grams, which can pose a risk for some individuals. While a celebrated superfood, beetroot is not suitable for everyone, and careful consideration is needed in certain health circumstances.

Quick Summary

Beetroot may be inadvisable for individuals with a history of kidney stones, low blood pressure, or irritable bowel syndrome due to its high oxalate and nitrate content. Consumption may also impact those taking blood pressure medication or with liver and blood sugar concerns.

Key Points

Kidney Stone Risk: Individuals with a history of calcium oxalate kidney stones should avoid or limit beetroot due to its high oxalate content.
Hypotension Warning: People with low blood pressure should consume beetroot cautiously, as its nitrate content can further lower blood pressure, causing dizziness or fainting.
Digestive Sensitivity: Those with IBS or sensitive stomachs may experience bloating and gas from the fructans (FODMAPs) in beetroot.
Medication Interference: Beetroot can amplify the effects of blood pressure medications and blood thinners; consult a doctor if you are on these drugs.
Moderation is Essential: Even without specific risks, excessive intake can lead to digestive upset, liver strain, and potentially concerning changes in urine or stool color.

Beetroot is lauded for its nutritional benefits, including its ability to lower blood pressure, improve athletic performance, and fight inflammation. However, for certain individuals, consuming beetroot or its concentrated juice can pose risks. Understanding these contraindications is crucial for enjoying the vegetable safely.

Who should limit or avoid beetroot?

Individuals with a history of kidney stones

Beetroot is rich in oxalates, which can contribute to the formation of calcium oxalate kidney stones in susceptible individuals. Boiling can reduce oxalate content, but those with a high risk should still be cautious, especially with concentrated juice.

People with low blood pressure (hypotension)

Beetroot's nitrates convert to nitric oxide, which lowers blood pressure. This is beneficial for hypertension but can be dangerous for those with existing hypotension, potentially causing dizziness or fainting.

Those with sensitive digestive systems

Beetroot contains fructans (FODMAPs) and fiber, which can lead to gas, bloating, and stomach cramps in individuals with IBS or sensitive stomachs.

Diabetics and those monitoring blood sugar

Beetroot contains natural sugars that can affect blood glucose, particularly in concentrated juice form. Diabetics should consume it in moderation and monitor their blood sugar.

Individuals on specific medications

Beetroot can interact with medications. It can enhance blood pressure-lowering effects of antihypertensives and potentially increase the risk of bleeding for those on blood thinners. Consultation with a doctor is advised.

Potential risk of anaphylaxis

Though rare, allergic reactions to beetroot, including severe anaphylaxis, are possible. Seek immediate medical help if symptoms like throat tightness occur.

Should you eat raw or cooked beetroot?


Feature	Raw Beetroot	Boiled Beetroot
Oxalate Content	Significantly higher (e.g., 67mg/100g)	Up to 60-80% lower than raw
Nutrient Density	Higher levels of heat-sensitive nutrients like Vitamin C	Some nutrient loss, but still retains minerals like potassium and fiber
Digestive Impact	Higher oxalate and fructan content may cause issues for sensitive individuals	More digestible fiber, potentially easier on sensitive stomachs
Best For	Those without kidney stone risk or digestive issues who want maximum nutrients.	Individuals concerned about oxalates or with sensitive digestion.

The importance of moderation

Even without specific risks, excessive beetroot can cause beeturia (harmless red urine/stool) and digestive problems. A varied diet is recommended over excessive intake of any single food.

Conclusion

While beneficial for many, beetroot is not suitable for everyone, especially those with a history of kidney stones, hypotension, or sensitive digestion. Its high oxalate and nitrate levels pose risks for certain individuals and can interact with medications. Moderation is key, and cooking can reduce oxalates. Always consult a healthcare professional before significant dietary changes and prioritize a balanced diet.

People with IBS or sensitive digestive systems should be mindful of their beetroot intake. It contains FODMAPs (fructans), which can trigger digestive symptoms like bloating and gas in sensitive individuals.

Yes, beetroot can interact with certain medications. It can enhance the effects of blood pressure-lowering drugs and may also increase the risk of bleeding for those on blood thinners. Always consult your doctor.

Diabetics can consume beetroot in moderation, but should be aware of its natural sugar content. This is especially true for beetroot juice, which has a higher concentration of sugars and can cause blood sugar spikes.

While often promoted for detox, excessive intake of beetroot may strain the liver due to its high betaine content, potentially causing an overaccumulation of minerals. More research is needed, but moderation is advised.

This phenomenon, known as 'beeturia,' is caused by the natural pigments (betalains) in beetroot. It is a harmless and temporary effect and is not a medical concern unless accompanied by other symptoms.
