When ingested, probiotics are live microorganisms that provide health advantages. Probiotics, which are usually beneficial bacteria, have a wide range of health and mental benefits. They may help with digestion, depression, and cardiovascular health. Some data suggests they may even improve the appearance of your skin. Probiotics are commonly obtained from supplements, but they can also be obtained from fermented foods. Probiotics found naturally in food and soil are known as natural probiotics. As humans, we've evolved to consume soil-based organisms as a natural supply of probiotics. This includes inadvertent consumption of trace amounts of organic dirt on your vegetables or from working or being outside near grass and soil. Probiotics are beneficial bacteria that live in our stomach and keep us healthy. After all, our forefathers didn't have probiotic pills back in the day; they obtained everything they needed from their natural surroundings and diets. Yogurt, kefir, kombucha, sauerkraut, pickles, miso, tempeh, kimchi, sourdough bread, and some cheeses are some of the most common fermented foods that naturally contain probiotics or have probiotics added to them.
