Is it Safe to Eat Raw Beets? Understanding the Health Benefits and Risks

4 min read

According to a 2021 review in Critical Reviews in Food Science and Nutrition, raw beets retain more heat-sensitive nutrients like Vitamin C and betalains than their cooked counterparts. While nutrient-dense, the question remains: is it safe to eat raw beets, and what precautions should be taken to avoid potential health risks?

Quick Summary

Eating raw beets is generally safe with proper preparation, but it is not recommended for everyone. High in nutrients, raw beets also contain oxalates and FODMAPs that can cause issues for susceptible individuals. Thorough cleaning is essential to prevent foodborne illness.

Key Points

  • Is it safe to eat raw beets?: Yes, it is safe for most people, but requires thorough cleaning to prevent foodborne illness.

  • Raw vs. Cooked Nutrients: Raw beets have higher levels of heat-sensitive nutrients like Vitamin C, folate, and betalains compared to cooked versions.

  • High in Oxalates: Raw beets contain more oxalates, which can be a concern for individuals prone to calcium-oxalate kidney stones.

  • Digestive Impact: The high FODMAP content in raw beets can cause digestive issues like bloating and gas for people with sensitive stomachs or IBS.

  • Blood Pressure Effects: The high nitrate content can significantly lower blood pressure, which should be monitored by individuals with low blood pressure or those on related medication.

  • Safe Preparation: Always scrub beets thoroughly, or peel them, and consider grating them for easier digestion.

  • Moderation is Key: As with any food, moderation is recommended to avoid adverse effects from excessive intake.

The Health Benefits of Eating Raw Beets

Raw beets are a powerhouse of nutrition, offering significant health benefits, especially compared to cooked versions. The absence of heat preserves a higher concentration of certain compounds that contribute to overall wellness.

Maximize Nutrient Intake

  • Vitamins and Antioxidants: Raw beets are an excellent source of Vitamin C, folate, and powerful antioxidants called betalains. These compounds are sensitive to heat and can be degraded or leached out during cooking. Betalains, responsible for the beet's vibrant color, help combat oxidative stress and inflammation in the body.
  • Dietary Nitrates: The high concentration of dietary nitrates in raw beets converts to nitric oxide in the body, which helps relax and widen blood vessels. This can lead to lower blood pressure, improved blood flow, and enhanced athletic performance. Studies suggest that raw beet juice may offer a more potent blood pressure-lowering effect than cooked beets due to higher nitrate levels.
  • Fiber for Digestive Health: Raw beets retain their maximum fiber content, which is crucial for digestive health. The high fiber can also aid in blood sugar regulation and promote feelings of fullness, supporting weight management.

Potential Health Risks and Considerations

While healthy, raw beets also come with considerations, particularly for certain individuals who may be more sensitive to specific compounds.

Oxalates and Kidney Stones

Raw beets contain a higher concentration of oxalates, natural compounds that can bind with calcium and contribute to the formation of calcium-oxalate kidney stones in susceptible individuals.

  • Risk Mitigation: For those with a history of kidney stones or a predisposition, eating beets in moderation is advised. Boiling beets can reduce their oxalate content by up to 60-80%.

FODMAPs and Digestive Discomfort

Raw beets are considered a high-FODMAP food due to their fructan content, a type of fermentable carbohydrate.

  • IBS Sensitivity: For individuals with Irritable Bowel Syndrome (IBS) or sensitive digestive systems, a high intake of raw beets can trigger symptoms like bloating, gas, and abdominal pain. Cooking can help break down some of the fructans, making the beets easier to digest.

Foodborne Illness

As a root vegetable, beets grow in soil, and improper washing can leave behind pathogens that cause foodborne illness. In 2010, several outbreaks of gastrointestinal illness in Finland were linked to raw grated beetroot served in canteens, highlighting the importance of proper handling.

  • Prevention: Thoroughly scrubbing beets under running water with a vegetable brush is essential to remove soil and potential bacteria. Peeling the beets can offer an extra layer of protection against contamination.

Lowered Blood Pressure and Dizziness

Due to their potent blood pressure-lowering effects, individuals with low blood pressure (hypotension) may experience dizziness or fatigue from consuming large amounts of raw beets, especially in concentrated forms like juice.

  • Monitor and Moderate: Those on blood pressure medication should monitor their intake and consult a doctor, as there may be additive effects.

Raw vs. Cooked Beets: A Comparative Analysis

To determine the best preparation method, consider the trade-offs between nutrient preservation and digestibility. The table below compares the nutritional profile and potential effects of raw versus cooked beets.

Feature Raw Beets Cooked (Boiled) Beets
Vitamin C Higher, heat-sensitive nutrient is preserved. Lower, as vitamin C leaches into cooking water.
Betalains (Antioxidants) Higher, maintains strong antioxidant effects. Lower, as heat can degrade these compounds.
Dietary Nitrates Higher, leads to more potent blood pressure effects. Lower, water-soluble nitrates can be lost during boiling.
Fiber Higher, supports digestive and blood sugar regulation. Lower, though the softened fiber is easier to digest.
Oxalates Higher content, potential risk for kidney stone formers. Lower, boiling leaches oxalates into the water.
Digestibility Can be harder to digest for sensitive stomachs. Easier to digest, less likely to cause gas and bloating.

Safe and Delicious Ways to Enjoy Raw Beets

For those who can tolerate them, incorporating raw beets into your diet is simple and delicious. Ensuring proper preparation is the most important step for safe consumption.

  1. Thorough Cleaning: Always wash beets thoroughly under running water and scrub with a vegetable brush to remove all traces of soil.
  2. Peel for Extra Safety: While the skin is edible, peeling can minimize the risk of residual soil-borne bacteria. For recipes that benefit from peeling, use a vegetable peeler to remove the outer layer.
  3. Grate and Shred: Grated or shredded raw beets add color, crunch, and nutrients to salads, slaws, and sandwiches.
  4. Juice and Blend: Raw beets can be added to smoothies or juiced for a nutrient-dense beverage. Pairing with fruits like apple or orange can balance the earthy flavor.
  5. Marinate for Flavor: Tossing shredded raw beets with an acidic vinaigrette containing vinegar or citrus juice not only adds flavor but can also have an antimicrobial effect.

Conclusion: Making an Informed Choice

Yes, it is safe to eat raw beets for most people, provided they are cleaned meticulously. Raw beets offer superior nutritional benefits, particularly higher levels of Vitamin C, betalains, and dietary nitrates, which support heart health and reduce inflammation. However, the higher concentration of oxalates and FODMAPs in their raw state means that individuals with kidney stone issues or sensitive digestive systems should exercise caution and consider cooking them instead. Ultimately, the choice between raw and cooked depends on your individual health needs and tolerance, but incorporating beets in any form is a positive step toward a healthier diet.

For general food safety recommendations, including handling produce, refer to the FDA's official guidelines.

Frequently Asked Questions

While uncommon, there is a risk of food poisoning from raw root vegetables like beets if they are not cleaned properly, as they can carry soil-borne bacteria. Thoroughly washing and scrubbing is essential.

Generally, yes. Raw beets have higher concentrations of heat-sensitive nutrients like Vitamin C, folate, and powerful antioxidants called betalains.

Individuals with a history of kidney stones or those with Irritable Bowel Syndrome (IBS) should be cautious due to the high oxalate and FODMAP content, respectively.

This phenomenon, known as 'beeturia,' is harmless and is caused by the betalain pigments found in beets. It is not a cause for medical concern.

Peeling raw beets can reduce the risk of consuming any residual soil-borne contaminants, though the skin itself is edible and nutrient-rich.

Excessive intake can potentially cause issues like gas and bloating due to high fiber and FODMAP content. Large amounts may also significantly lower blood pressure.

Boiling beets can reduce their oxalate content by a significant percentage. Cooking and discarding the water is an effective way to lower the oxalate load.
