Gut health: When the protective lining of the gut is inflamed, the body is more vulnerable to allergies, infections, and yeast overgrowth. Lucky for us, lactic acid bacteria have the ability to reduce intestinal permeability, thereby restoring the net. They also create pH changes in the GI tract that make it difficult for pathogens to survive. Sayonara, leaky gut.
Nutritional boost: The fermentation process makes nutrients more bio-available for the body to absorb. For instance, the amount of vitamin C in sauerkraut is significantly higher than in the same serving of fresh cabbage. This is because the vitamin C in fresh cabbage is woven into the fibrous plant walls, so it's less readily available for the intestinal cells to take in.
Detoxification: Both the beneficial bacteria and the active enzymes act as potent detoxifiers in the intestines. Beneficial microbes ferment fiber from foods like onions, garlic, leeks, artichokes, and chicory root as a means to fuel their own growth. These foods are also called prebiotics, known for amping up the detoxification process.
Sugar cravings: Yeast and pathogenic bacteria feed off sugar. The more sugar you ingest, the more hospitable you're making your intestines for harmful microbes. This creates a less-than-ideal cycle: the more sugar you eat, the more "bad" bacteria you have…which makes you crave more sugar. The reverse, however, is also true, meaning the fewer of these "bad" bacteria you have, the less you crave sugar.
