• symptoms associated with anxiety, depression, autism spectrum disorders, and obsessive-compulsive disorder

Furthermore, it is suggested that fermented foods like sauerkraut may elevate mood by boosting your gut's ability to absorb essential minerals that regulate mood, such as magnesium and zinc.

However, it’s important to note that some studies caution that certain compounds found in sauerkraut may interact negatively with monoamine oxidase inhibitors (MAOIs), which are commonly prescribed for treating depression, anxiety disorders, and Parkinson’s disease. Individuals on these medications are advised to seek guidance from a healthcare professional before introducing sauerkraut into their meal plans.

6. Potentially Lowers the Risk of Certain Cancers

Cabbage, the primary ingredient in sauerkraut, is rich in antioxidants and an array of beneficial phytochemicals that may play a role in reducing the risk of specific cancers. The fermentation process that cabbage undergoes not only enhances its flavor but also generates unique plant compounds that can inhibit the growth of precancerous cells.

For instance, a study involving Polish immigrants in Canada highlighted that a higher intake of cabbage and sauerkraut was associated with a significant decrease in the risk of breast cancer. The advantageous compounds found in cabbage may offer protective effects against various types of cancer, including:

• colon cancer
• liver cancer
• stomach cancer
• prostate cancer
• oral cancer

It is essential to note that research in this area remains somewhat limited, and not all studies have yielded consistent findings. Therefore, further investigations are necessary to draw robust conclusions regarding these potential benefits. Nevertheless, the presence of these beneficial plant compounds in sauerkraut suggests it may help in reducing the likelihood of cancer cell development and proliferation.

7. Potential Benefits for Heart Health

Sauerkraut, a fermented cabbage dish, may play a significant role in promoting a healthier heart. This is primarily due to its abundant content of fiber and probiotics, which can aid in lowering cholesterol levels effectively. The probiotics present in sauerkraut have also been shown to provide some benefits to individuals dealing with hypertension, potentially helping to manage blood pressure levels more effectively.

Additionally, sauerkraut is notable for being one of the few plant-based sources of menaquinone, commonly referred to as vitamin K2. This essential nutrient is believed to reduce the risk of heart disease by preventing harmful calcium deposits from building up in the arteries. With its rich combination of fiber, probiotics, and vitamin K2, sauerkraut may assist in lowering cholesterol levels, offer slight improvements in blood pressure, and ultimately contribute to a decreased risk of heart disease.

8. Promotes Enhanced Bone Strength

The presence of vitamin K2 in sauerkraut is crucial for maintaining optimal bone health. This specific vitamin activates proteins that bind to calcium, which is the primary mineral essential for strong bones. Experts suggest that this process significantly contributes to the development of stronger and healthier bones. Numerous studies have indicated that vitamin K2 offers considerable advantages for bone health. Despite this, it remains uncertain whether the amount of vitamin K2 found in sauerkraut is sufficient to yield significant health benefits. Further research is warranted to establish its effectiveness.

How to Shop for Sauerkraut

Sauerkraut can be easily found in most grocery stores, yet not all versions available will provide the same level of quality and health benefits.

To maximize the nutritional advantages of store-bought sauerkraut, keep the following straightforward tips in mind:

• Avoid Pasteurized Varieties: The majority of commercially available sauerkraut is pasteurized, a process that eliminates the beneficial probiotics. Look for refrigerated options, as these are less likely to be pasteurized, but always verify by reading the label.
• Avoid Preservatives: Numerous brands of store-bought sauerkraut include preservatives, which may diminish the probiotic content.
• Avoid Added Sugar: Authentic sauerkraut should consist of only two primary ingredients: cabbage (patta gobhi) and salt. While some varieties may incorporate extra vegetables, steer clear of those that include sugar or any other additives.

To reap the maximum health benefits from store-bought sauerkraut, choose non-pasteurized options that are free from added sugars and preservatives.

How to Prepare Sauerkraut

To fully reap the health benefits of sauerkraut, crafting it at home is a wonderful option. The process is straightforward, cost-effective, and quite enjoyable. Here’s a simple guide to get you started:

Classic Sauerkraut Recipe

Ingredients

• 1 medium green cabbage (patta gobhi)
• 1 tablespoon (15 mL) of non-iodized salt
• 2–3 carrots (gajar), shredded (optional)
• 2–3 cloves of garlic (lahsun), finely chopped (optional)

Prepare a 1-quart (1-liter) jar to store your sauerkraut, a 4-ounce (120-mL) smaller jar for pressing the mixture, and a kitchen scale for weighing your cabbage.

Instructions

1. If you choose to include carrots and garlic, start by placing these ingredients in a large mixing bowl.
2. Remove the outer leaves of the cabbage, saving one intact leaf for later. Cut the cabbage into quarters while leaving the core intact to facilitate shredding.
3. Shred the cabbage quarters into the bowl containing the carrot and garlic mixture. Add enough shredded cabbage to reach a total weight of 28 ounces (about 800 grams), which is suitable for a 1-quart (1-liter) jar.
4. Incorporate the salt into the cabbage mixture, massaging it for several minutes until you notice brine beginning to form at the bottom of the bowl.
5. Transfer the cabbage mixture into your clean 1-quart (1-liter) jar, pressing it down firmly to eliminate air pockets. Pour any remaining brine over the top. It is crucial that the mixture is fully submerged to prevent the growth of harmful bacteria.
6. Trim the reserved cabbage leaf to fit snugly inside the jar opening, placing it on top of the mixture to keep the vegetables submerged.
7. Add the 4-ounce (120-mL) jelly jar, without a lid, into the larger jar on top of the cabbage mixture. This will help keep your veggies submerged during the fermentation process.
8. Secure the lid onto your 1-quart (1-liter) jar but leave it slightly loose to allow gases to escape during fermentation.
9. Store the jar at room temperature, away from direct sunlight, for a duration of 1–4 weeks.

Bear in mind that starting with a larger head of cabbage will result in a sweeter and more flavorful sauerkraut.

If you’re eager to sample your creation, you can start tasting it after just 7 days. Remember, the longer it ferments, the more robust the flavor becomes.

Here are some exciting variations of sauerkraut to try:

• beetroot sauerkraut
• dilly delight sauerkraut
• kimchi-style sauerkraut

By following these steps, you can easily create your own delicious, budget-friendly sauerkraut right at home.
