What Are the Benefits of Sauerkraut?

Sauerkraut is a tangy food with a characteristic flavor, made by fermenting cabbage with an appropriate salt level and conditions. What does fermentation add?Microorganisms produce acid from sugars in the cabbage, changing its taste and texture. Not every fermented food has proven probiotic benefits; a “live cultures” statement alone does not establish such a health effect. How should nutrition be assessed?Nutrient and sodium contents vary by product; consider the label and portion size. Do not arbitrarily reduce the salt in a fermentation recipe to lower sodium. Which foods does it complement?Its acidity can complement sautéed, fried, and grilled meats. It can also add crunch and flavor to sandwiches and toasties. How should it be prepared and stored at home?Follow a tested recipe from a reliable source such as NCHFP, including its salt, temperature, time, and container requirements. Keep the cabbage under brine as specified in the recipe. Refrigerate the completed kraut in a covered container; follow the label for commercial products. What does a white film mean?A surface film may be yeast, but its color alone does not establish safety. Follow the recipe’s surface-care instructions during controlled fermentation. Discard stored kraut without tasting if there is mold, sliminess, a rotten odor, or doubt about safety; removing the surface film does not make it safe. Vinegar pickling and fermentation are different processes; do not interchange their recipes or storage conditions.
