Fermentation is a process that’s used to produce some of our favorite foods and beverages — things like wine, beer, breads, cheese, chocolate, coffee and yogurt, for example. Throughout history, fermenting foods gave our ancestors the option of prolonging the freshness of produce and milk that was available to them during the different seasons. Today, you can make a large batch of fermented foods, such as sauerkraut or yogurt, to have ready to eat in your refrigerator that should last a relatively long time.
Why are fermented foods good for you? Eating fermented (or “cultured”) foods is the most convenient way to obtain a daily dose of beneficial probiotic bacteria.
