How much sauerkraut is safe to eat per day?

4 min read

According to a 2018 study, participants consumed up to 75 grams of sauerkraut per day with health benefits. While this research offers a guideline, the amount of sauerkraut that is safe and beneficial to eat daily can vary significantly by individual, especially regarding probiotic benefits and potential side effects.

Quick Summary

This guide explains the ideal daily intake of sauerkraut, highlighting the importance of starting slow to avoid digestive discomfort. It explores the benefits of fermented cabbage, explains the difference between raw and pasteurized varieties, and details potential risks for certain individuals. Practical tips for incorporating sauerkraut into your diet are also included.

Key Points

  • Start Slowly: Begin with a small amount, like one teaspoon, to allow your digestive system to acclimate to the new probiotics and fiber.

  • Increase Gradually: If you feel comfortable, you can slowly increase your daily intake, depending on your body's tolerance.

  • Choose Raw for Probiotics: To get the full gut health benefits, choose raw, unpasteurized sauerkraut, which is typically found in the refrigerated section of stores.

  • Mind the Sodium: Sauerkraut is high in sodium due to the fermentation process, so those with high blood pressure or on a low-sodium diet should watch their intake.

  • Monitor for Side Effects: Excessive intake can cause digestive discomfort like gas, bloating, or diarrhea; reduce your portion size if you experience these symptoms.

  • Consider Health Conditions: Individuals with histamine intolerance or those on MAOI medications should consult a healthcare professional before adding sauerkraut to their diet.

  • Consistency Over Quantity: Regular, small portions are often more beneficial for long-term gut health than large, infrequent servings.

Finding Your Optimal Sauerkraut Serving

For many, incorporating fermented foods like sauerkraut is a way to boost gut health. However, there is no one-size-fits-all answer to how much sauerkraut is safe to eat per day. The ideal amount depends on your body's tolerance and your health goals. A cautious approach is best, particularly for those new to fermented foods.

Start Small and Listen to Your Body

If you are just beginning to add sauerkraut to your diet, it is recommended to start with a very small serving, such as a teaspoon or a single forkful per day. This allows your gut microbiome time to adjust to the influx of new bacteria without causing discomfort like bloating, gas, or diarrhea. Over several weeks, if you feel comfortable, you can gradually increase your intake.

Different Recommendations for Different Goals

Research provides varying daily consumption suggestions, and many sources suggest a daily serving size based on an average individual's tolerance. For general gut health maintenance, consuming a small amount regularly is a common recommendation. Some studies have used larger amounts to achieve specific health outcomes, but these are not always suitable for everyone and should not be used as a starting point.

  • For General Probiotic Benefits: A regular, small and consistent amount, like a tablespoon or two, is often sufficient to introduce beneficial bacteria to the gut.
  • For Specific Digestive Support (like IBS): One 2018 clinical trial with IBS patients found that consuming pasteurized or unpasteurized sauerkraut led to a significant reduction in symptoms. However, those consuming the unpasteurized version also saw changes to their gut microbiota. Some suggestions involve a daily amount over a period of weeks, but consulting a healthcare professional is best.

Raw vs. Pasteurized Sauerkraut: A Key Difference

If your goal is to consume live, beneficial probiotics, the type of sauerkraut you choose is critical. Only raw, unpasteurized sauerkraut contains these live cultures, as the heating process involved in pasteurization kills all bacteria.

Feature Raw, Unpasteurized Sauerkraut Pasteurized Sauerkraut
Probiotic Content Contains live, beneficial bacteria (probiotics). Probiotics are killed during the heating process.
Location in Store Found in the refrigerated section of most grocery or health food stores. Found in jars or cans on regular, unrefrigerated shelves.
Shelf Life Shorter shelf life due to live bacterial activity; must be refrigerated. Long, shelf-stable due to the pasteurization process.
Texture Generally fresher and crunchier. Softer, less crunchy texture.

Potential Side Effects and Precautions

While sauerkraut is a highly nutritious food, excessive consumption can lead to some side effects, and it's not suitable for everyone.

  • High Sodium Content: Sauerkraut is fermented with salt, which results in a high sodium content. Individuals with high blood pressure or those on a sodium-restricted diet should be mindful of their intake. Opting for a low-sodium brand or making homemade sauerkraut with less salt can help manage this.
  • Digestive Discomfort: For some, especially when first starting out, the fiber and probiotics in sauerkraut can cause gas, bloating, and diarrhea. This is often a sign of overconsumption and can be managed by reducing the portion size and introducing it more slowly.
  • Histamine Intolerance: Sauerkraut is a histamine-rich food, which can trigger adverse reactions in individuals with histamine intolerance. Symptoms can include headaches, digestive issues, or allergy-like symptoms.
  • Drug Interactions: Sauerkraut can contain high levels of tyramine, which may interact dangerously with certain antidepressant medications called monoamine oxidase inhibitors (MAOIs). Anyone on these medications should consult a healthcare provider before consuming sauerkraut.

How to Safely Incorporate Sauerkraut into Your Diet

For a safe and enjoyable experience, follow these steps to add sauerkraut to your daily routine:

  1. Introduce it gradually: Begin with a small amount, like one teaspoon, to assess your tolerance.
  2. Choose raw for probiotics: If probiotic benefits are your goal, select raw, unpasteurized sauerkraut from the refrigerated section of the store.
  3. Use it as a condiment: Add it to salads, sandwiches, tacos, or bowls. For probiotic benefits, add it after cooking to preserve the live bacteria.
  4. Try different varieties: Experiment with different brands or make your own to control the sodium and flavor profile.

Consistency is more important than quantity when consuming fermented foods for gut health. Eating a small, sustainable amount regularly is more effective than large, sporadic servings. Listening to your body is the best guide for determining the right amount for you.

Conclusion

While a universally "safe" amount of sauerkraut per day is difficult to pinpoint due to individual differences, a general guideline is to start with a small serving and gradually increase it as tolerated. For maximum probiotic benefits, raw, unpasteurized versions are best. Important considerations include sauerkraut's high sodium content and potential interactions with certain medications like MAOIs. By starting slow and monitoring your body's response, most people can safely enjoy the digestive and nutritional benefits of this fermented food. Ultimately, your body's signals are the most reliable indicator for finding your optimal daily dose.

Comparison of Raw vs. Pasteurized Sauerkraut

Aspect Raw, Unpasteurized Sauerkraut Pasteurized Sauerkraut
Availability Refrigerated section, health food stores Shelf-stable jars/cans, any supermarket
Processing Natural fermentation, not heated Heat-treated to kill bacteria
Probiotics Present (live cultures) Absent (killed by heat)
Flavor Tangy, complex, and "live" Milder, less complex, often more acidic
Texture Crunchy and firm Softer, less crunchy
Sodium Varies by brand; can be high Varies by brand; can be high
Cost Typically more expensive Generally cheaper

For those prioritizing gut health, the probiotic benefits of raw sauerkraut make it the superior choice, despite the higher cost. However, pasteurized versions still offer fiber and nutrients, including some prebiotic content.
