Why do I feel sick after drinking wheatgrass? The surprising reasons behind the nausea

4 min read

While celebrated as a potent superfood, a small percentage of people experience nausea, headaches, and digestive upset after consuming wheatgrass. Though often linked to its detoxifying properties, this reaction can result from several factors, including the rapid influx of nutrients or pre-existing sensitivities. Understanding why your body reacts this way is the key to incorporating wheatgrass safely into your diet.

Quick Summary

Several factors can cause nausea after drinking wheatgrass, including a temporary detox reaction, consuming too much too quickly, or individual sensitivities. Digestive issues from potent enzymes or nutrient concentration are common culprits. Ensuring proper preparation, starting with small doses, and listening to your body can help mitigate these adverse effects and make the experience more pleasant.

Key Points

  • Detox Reaction: A temporary reaction to wheatgrass's powerful cleansing properties may cause nausea and headaches as your body expels stored toxins.

  • Start Slowly: Consuming too much wheatgrass too quickly can overwhelm your digestive system. Begin with a 1-ounce shot and increase gradually.

  • Empty Stomach: Drinking wheatgrass on an empty stomach can intensify detox symptoms and cause nausea; try consuming it with a light snack.

  • Digestive Sensitivity: Some individuals may react strongly to the potent enzymes in wheatgrass, leading to cramps and an upset stomach.

  • Contamination Risk: Improperly grown wheatgrass can contain mold or bacteria, leading to adverse digestive reactions. Use organic, well-sourced products.

  • Consider Diluting: Diluting wheatgrass juice with water or other mild juices can reduce its intensity and improve palatability.

  • Proper Preparation: Wash fresh wheatgrass thoroughly and use a masticating juicer for best results and to minimize contamination risk.

Understanding the 'Detox' Reaction

One of the most frequently cited reasons people feel sick is the so-called 'detox' reaction. Wheatgrass is a powerful cleanser, rich in chlorophyll and enzymes that help the body expel stored toxins, heavy metals, and other waste products. For individuals whose systems are not used to this rapid cleansing, the process can trigger flu-like symptoms. As the body purges these toxins, you might experience temporary nausea, headaches, fatigue, or mild fever. This discomfort typically subsides as your body adjusts, and it is a signal to reduce your dosage and ease into the process more gently.

The Impact of Dosage and Consumption Habits

Perhaps the most common cause of wheatgrass-induced sickness is simply drinking too much, too fast. The concentration of vitamins, minerals, and enzymes in a single shot of wheatgrass is equivalent to a significant amount of green vegetables. Bombarding your system with this potent liquid can shock your digestive tract, leading to nausea, cramping, and an upset stomach. Starting with a small dose, such as a 1-ounce shot, is highly recommended to allow your body time to acclimate. A common beginner's mistake is consuming a large shot on an empty stomach, which can exacerbate the issue.

The Role of Digestive Sensitivity

Some individuals have a more sensitive digestive system that reacts strongly to the potent enzymes in wheatgrass. The high concentration of digestive enzymes and a sudden influx of chlorophyll can be overwhelming, leading to nausea and other gastrointestinal discomfort. Furthermore, the fibrous nature of the plant, especially if blended rather than juiced, can contribute to digestive upset as the body struggles to process the roughage. Eating a small snack beforehand can help buffer the effects and make the process easier on your stomach.

Contamination Concerns

While less common, contamination is a potential cause of feeling unwell. Wheatgrass can be susceptible to mold and bacteria if not grown or stored properly. Harmful bacteria or mold can grow on the ungerminated seeds and affect the grass, leading to digestive issues and food poisoning-like symptoms. It is crucial to source your wheatgrass from reputable providers or, if growing at home, to maintain a clean environment to prevent contamination. Rinsing the grass thoroughly before juicing is an important step to mitigate this risk.

Wheatgrass vs. Barley Grass: A Comparison of Effects

For those who experience persistent nausea with wheatgrass, exploring alternatives like barley grass might be beneficial. Barley grass offers a similar nutritional profile but is often considered milder on the stomach.

Feature Wheatgrass Barley Grass
Taste Sweet and intense Mild and not as sweet
Nutrient Potency Highly concentrated, powerful detoxifier Slightly milder, easier on sensitive systems
Detox Reaction More common and pronounced Less common, fewer reported side effects
Fiber Content Can be fibrous, causing digestive issues if not juiced properly Generally more palatable for beginners

Strategies to Mitigate Nausea

If you are committed to incorporating wheatgrass into your diet, several strategies can help reduce the likelihood of feeling sick. The key is to start slow and listen to your body.

  • Start with a small dosage: Begin with a 1-ounce shot and slowly increase the amount over several weeks as your body adjusts.
  • Consume with a snack: Avoid drinking wheatgrass on an empty stomach. A piece of fruit or a light meal can help prevent shock to your system.
  • Stay hydrated: Drinking plenty of water throughout the day, especially when consuming wheatgrass, helps flush out toxins and supports the detox process.
  • Dilute the juice: If the taste or potency is overwhelming, dilute the wheatgrass with water, apple juice, or cucumber juice to make it more palatable.
  • Ensure quality: Use organic, fresh wheatgrass from a reliable source to minimize the risk of bacterial or mold contamination.
  • Consider powder form: If fresh juice is too intense, wheatgrass powder or tablets might be a gentler option. Follow the recommended serving size on the package.

Conclusion: Finding the Right Balance

Feeling sick after drinking wheatgrass is a relatively common experience, but it does not mean this superfood is unsuitable for you. By understanding the potential causes—from intense detox reactions and dosage issues to digestive sensitivity and contamination—you can take proactive steps to prevent nausea. Start with a small, diluted amount, consume it with a light snack, and ensure the product is high-quality. If the problem persists, consulting a healthcare professional is advisable to rule out any underlying allergies or sensitivities. With patience and the right approach, many individuals can overcome the initial discomfort and reap the many nutritional benefits of wheatgrass.

A Note on Purity

For fresh wheatgrass, proper washing is critical. A study on guinea pigs showed that chlorophyll-rich vegetables could reduce radiation's lethal effects. Similarly, the Hippocrates Institute emphasizes the importance of using indoor-grown wheatgrass in controlled environments for optimal health benefits.



How to Prepare Wheatgrass Safely

To ensure safety, wash your fresh wheatgrass thoroughly and consider using a masticating juicer, which preserves more nutrients than a centrifugal juicer. If using powder, follow the package instructions carefully.
