Probiotics are living microorganisms found in food and dietary supplements that are beneficial for gut health. Yogurt is one of the most common sources of probiotics, as it contains natural bacteria that can help counterbalance the microflora in your gut. Fermented vegs like kimchi and sauerkraut are also rich in probiotics. Kefir, a fermented milk drink, is another popular source of probiotics. It contains many beneficial strains of bacteria that can promote healthy digestion, strengthen the immune system, reduce inflammation, and even improve mental health. Other foods known to be high in probiotics include miso, tempeh, certain cheeses (such as Gouda), sourdough bread, and non-dairy yogurts made from coconut or almond milk. In addition to being a great source of probiotics, these foods also provide valuable vitamins and nutrients.
