These foods, which include yogurt, kefir, sauerkraut, and kimchi, are rich in probiotics—beneficial bacteria that help balance the digestive system. Fermented foods can improve nutrient absorption, boost the immune system, and may even reduce the risk of chronic diseases. Additionally, the consumption of these foods has been linked to improved mental health and a better overall mood, illustrating their holistic health benefits.
