Probiotics play a significant role in nutrition by promoting gut health and supporting the digestive system. These beneficial bacteria help maintain a healthy balance of gut microbiota, enhancing overall gut function and potentially improving immune responses. Regular consumption of probiotics, found in foods like yogurt, kefir, and fermented vegetables, can aid digestion and reduce gastrointestinal issues like bloating and constipation. Additionally, emerging research suggests a link between gut health and mental wellness, underscoring the importance of probiotics in a balanced diet.
