Fermented foods are products created through the process of fermentation, where microorganisms like bacteria, yeast, or molds convert sugars and starches into acids, gases, or alcohol. This process not only preserves food but also enhances its flavor and nutritional value. Common examples include yogurt, kimchi, and sauerkraut. The health benefits of fermented foods are widely recognized, as they are rich in probiotics, which can improve gut health and boost the immune system. Incorporating these foods into your diet can lead to better digestion and overall well-being, making them a valuable addition to a balanced diet.
