The gut microbiome significantly impacts overall health due to its role in digestion, metabolism, and immune system regulation. A diverse microbiome contributes to better nutrient absorption and can influence body weight and inflammation levels. Imbalances in gut bacteria may lead to health issues such as obesity, diabetes, and gastrointestinal disorders. Furthermore, emerging research shows that gut health may affect mental health and mood, highlighting the importance of a diet rich in fiber and probiotics to support a healthy microbiome.
