| Sauerkraut is fermented cabbage made by combining cabbage and salt and allowing naturally occurring microorganisms to ferment the vegetables. It can offer numerous gut health benefits because of its fibre, live microorganisms and compounds created during fermentation. These may support digestion, regular bowel movements and a healthy gut microbiome. |
Cabbage, salt and a little time can create much more than a tangy side dish. For centuries, people have used fermentation to preserve food and extend its shelf life. Today, fermented foods such as sauerkraut have found a place on plates around the world, both for their distinctive sour flavour and the potential benefits they can offer.
So, what is the connection between sauerkraut and gut health? What happens when cabbage goes through fermentation, and what does that mean for your digestive system?
What Is Sauerkraut?
Sauerkraut is finely shredded cabbage that undergoes fermentation, traditionally using just cabbage and salt. During the process, naturally occurring lactic acid bacteria break down sugars in the cabbage and produce lactic acid and other compounds.
This gradually lowers the acidity of the cabbage, giving it the characteristic tangy flavour while creating an environment that helps preserve the food. Fermentation also changes its nutritional profile, producing organic acids, amino acids and other bioactive compounds along the way.
What Does Unpasteurized Sauerkraut Contain?
If the cabbage has not undergone heat treatment after fermentation, it can retain live microorganisms created during the fermentation process. These include lactic acid bacteria, some of which can survive the journey through the digestive system and interact with the existing microbial community in the gut.
Gut Health Benefits of Sauerkraut
Fermentation gives sauerkraut several properties that make it particularly interesting from a gut health perspective:
- Fibre from cabbage that provides food for certain gut microorganisms
- Live microorganisms that can be present in unpasteurized varieties
- Organic acids and other metabolites created during fermentation
- Plant compounds naturally found in cabbage
- A relatively low-calorie way to add vegetables and fibre to meals
Together, these components may have a range of beneficial effects on your gut:
May Support Digestion
Fibre plays an important role in keeping your digestive system moving. It adds bulk to stool and supports regular bowel movements, while also providing food for certain microorganisms in the gut.
Fermentation adds another dimension. The microorganisms involved in the process break down some of the cabbage’s natural sugars and produce organic acids and other compounds.
May Help Support Regular Bowel Movements
If your digestive system tends to move slowly, fibre can be your friend. Getting enough fibre throughout the day can help maintain regular bowel movements, particularly when you also drink enough fluids and eat a varied diet.
May Support a Healthy Gut Microbiome
Your gut contains a vast community of microorganisms, and what you eat can influence the environment in which they live. This fermented vegetable brings together several components that can interact with this microbial community.
The fibre provides a food source for certain beneficial bacteria, while live microorganisms in unpasteurized varieties can add to the microbial mix. Fermentation also creates metabolites and organic acids that can influence the gut environment.
May Provide Beneficial Compounds Created During Fermentation
Fermentation transforms the food in ways that go beyond preserving it. As microorganisms break down sugars in the cabbage, they produce lactic acid and other metabolites. These fermentation-derived compounds can interact with the gut microbiome and the intestinal environment.
The process also changes some of the plant compounds naturally present in cabbage, creating a more complex nutritional profile. This is part of what makes fermented foods so interesting. Their potential benefits come from the interaction between the original food, the microorganisms involved in fermentation and the compounds produced during the process.
May Support Healthy Weight Management
Sauerkraut can also fit easily into meals designed to support healthy weight management. Like many vegetables, it provides relatively few calories while contributing fibre. Fibre can help you feel fuller for longer, which may make meals more satisfying and help you manage your overall food intake.
Think of it as part of a balanced meal rather than a standalone weight-loss food. Add it to meals with vegetables, whole grains and a source of protein for a more satisfying plate.
How to Include Sauerkraut in Your Diet
You don’t need a large serving to enjoy fermented cabbage. A small portion alongside a meal is a great place to start.
Here are a few things to consider:
- Choose unpasteurized varieties. If you want the live microorganisms associated with fermentation, look for refrigerated, unpasteurized products. Heat treatment can reduce or eliminate these microorganisms.
- Check the ingredients. Traditional sauerkraut can be remarkably simple, often containing little more than cabbage and salt. Look for products without unnecessary preservatives or added sugar.
- Start small. If fermented foods are new to your diet, introduce them gradually. A sudden increase in fermented foods and fibre may cause temporary bloating or digestive discomfort in some people.
- Watch the sodium. Salt plays an important role in fermentation, so this food can contribute a significant amount of sodium to your diet. Keep your overall sodium intake in mind.
- Make it part of a meal. Add it alongside eggs, meat, potatoes, rice or vegetables, or use it to bring a bright, tangy flavour to sandwiches, wraps and salads.

FAQs
Is sauerkraut good for gut health?
Sauerkraut can be a useful addition to a gut-friendly diet because it provides fibre and, when unpasteurized, live microorganisms. Fermentation also creates organic acids and other compounds that can interact with the gut microbiome.
Is sauerkraut a probiotic food?
Probiotic foods contain specific live microorganisms that provide a demonstrated health benefit when consumed in adequate amounts. Unpasteurized fermented cabbage can contain live microorganisms, including lactic acid bacteria. When these microorganisms meet the criteria for a probiotic, the fermented cabbage can be considered a probiotic food.
Is raw or unpasteurized sauerkraut better?
If you want to consume the live microorganisms created during fermentation, choose an unpasteurized product that has been properly fermented and stored. Pasteurization involves heat treatment, which can reduce or eliminate these live microorganisms.
How much sauerkraut should I eat?
There is no single amount that everyone needs. If you are new to fermented foods, start with a small serving and see how your body responds. You can gradually increase the amount if you tolerate it well.
Can you eat sauerkraut every day?
Yes. A small serving can form part of a varied everyday diet if you enjoy it and tolerate it well. Eating a range of vegetables, fibre-rich foods and fermented foods gives your gut a broader variety of nutrients and compounds to work with.
Can sauerkraut cause bloating?
It can. The combination of fermentation and fibre may cause temporary gas or bloating in some people, particularly when they introduce large amounts suddenly. Starting with a small serving can give your digestive system time to adjust.
