Fermented milk is a dairy product created by adding specific bacteria to milk, which helps to break down lactose and produce lactic acid. This process not only thickens the milk but also enhances its flavor and nutritional value. Common types of fermented milk include yogurt, kefir, and buttermilk. The fermentation process can improve digestion and increase the availability of nutrients. Fermented milk products are often rich in probiotics, which are beneficial bacteria that support gut health. These products are enjoyed worldwide and can be used in various dishes or consumed on their own.
