Fermented food every day: cabbage, kimchi, kefir
A probiotic capsule costs two thousand and contains several billion bacteria of two or three species. A spoonful of live sauerkraut contains dozens of species, billions per gram, and costs about as much as a jar. Fermented food is the cheapest and most reliable way to feed the gut live cultures, and in this method it is on the plate every day. Section — microbiome and intolerances.
What is live and what is not
| Product | Live | Note |
|---|---|---|
| Vinegar-free sauerkraut from the refrigerator | yes | look for “live” or “unpasteurized” on the label; or make your own |
| “Pickled” cabbage with vinegar, from the shelf | no | vinegar instead of fermentation |
| Kimchi | yes | spicy; check the sugar content |
| Kefir, plain unsweetened yogurt | yes | less lactose than milk; check if intolerant |
| “Fruit” yogurt | conditionally | sugar cancels out the benefits |
| Brined pickles, barrel-fermented | yes | not pickled with vinegar |
| Miso, natto | yes | soy; rarely found on our plates |
| Kombucha | conditionally | sugar; choose one with no residual sugar |
How much and how to introduce it
The goal is 30-100 g of sauerkraut or kimchi per day, or a glass of kefir, or all of them in smaller portions. Start with a teaspoon of cabbage with lunch: if you introduce a whole plate at once, the bacteria will cause bloating for three days. Double the amount every three days. The brine is live too; use a tablespoon in a salad instead of vinegar. About cabbage — sauerkraut.
Make it yourself in 10 minutes
1 kg cabbage, 20 g salt (2%), carrot if desired. Shred the cabbage, massage it with the salt until it releases juice, pack it firmly into a jar so that the juice covers the cabbage, cover, leave at room temperature for 3-7 days, and pierce it once a day. It is ready when sour and free of any strong smell. Refrigerated, it keeps for months. This is the cheapest probiotic available, and it definitely contains no sugar or vinegar.
Who should be cautious
With histamine intolerance, fermented foods can cause headaches and flushing; check by eliminating them. With IBS, start with a teaspoon and monitor your response. With active gastritis and erosions, acidic foods may burn. With lactose intolerance, kefir and yogurt are often tolerated — the bacteria have consumed some of the lactose — but check your response. About intolerances — dairy and gluten.
Frequently asked questions
Is a probiotic capsule still needed after antibiotics?
You can add a supplement as prescribed by a doctor. But cabbage and kefir from the first day after the course are the foundation that works without capsules.
Is kefir not sugar?
A glass of kefir contains 4-6 g of carbohydrates; some of the lactose has been consumed by bacteria. It is acceptable for the method; on strict keto, count it.
Is store-bought “sauerkraut” live?
Only if it is kept refrigerated and contains no vinegar. From the shelf at room temperature, it has been pasteurized and contains no bacteria.
- Digestion and fasting: why the gut loves pausesDuring a pause without food, the gut turns on “clean-up,” which does not start with snacks. Why bloating and IBS quiet down during fasting, how to end the pause, and what happens with the gallbladder.
- Microbiome on a Low-Carb Diet: Who Lives in the Gut Without SugarBacteria eat what you eat. Without sugar and flour, the composition changes in a month: less gas and fewer cravings for sweets, more butyric acid. What happens and how to help.
- Dairy and gluten: test them for 30 days instead of guessingThe two most common intolerances. Lactose and casein are different problems; gluten disappears on the method by itself. An elimination and reintroduction protocol that gives an honest answer without tests.
- Fiber without grains: 30 grams from vegetables, seeds, and berries“There won’t be enough fiber without bread” — a myth. The method’s food table, two types of fiber, and a 30-gram day without a single grain.
- Loose stools and fats: when fat suddenly becomes too muchFat increased from 30 to 70% in one day — the gallbladder and pancreas did not have time to adapt. Why this happens and how to increase fat so that the intestines keep up.
- Constipation on a low-carb diet: four causes and what to doI cut out bread and grains — and my bowel movements disappeared. This is not “keto is harmful”; it means too few vegetables, water, salt, and magnesium. A breakdown by cause and a one-week plan.
