Gut bacteria, also known as gut microbiota, are tiny microorganisms that live in the digestive tract. They play a crucial role in breaking down food, absorbing nutrients, and supporting the immune system. A balanced gut microbiome can contribute to overall health and well-being. These bacteria can be influenced by various factors, including diet, lifestyle, and medications. Foods rich in fiber, such as fruits and vegetables, can promote the growth of beneficial bacteria. Conversely, a diet high in sugar and processed foods may lead to an imbalance, potentially resulting in digestive issues and other health problems.
