Fermented foods are foods that have been through a process of fermentation, in which microorganisms such as bacteria or yeast transform the food.
This process can add beneficial probiotics to the food, and also change its texture and flavor. Fermented foods have been eaten for centuries all over the world, and are especially common in Asian cuisine.
Some examples of fermented foods include kimchi, sauerkraut, yogurt, and kefir.
Fermented foods are becoming more popular in the Western world as people become interested in probiotics and gut health.
Some studies have shown that eating fermented foods can help improve digestion, boost immunity, and even promote weight loss.
If you're looking to add more fermented foods to your diet, start with small amounts and gradually increase as your body gets used to them.
You can find fermented foods in most grocery stores, or you can make them at home using a fermentation kit.
