Intestinal flora, also known as gut microbiota, refers to the diverse community of microorganisms living in the digestive tract. These microorganisms include bacteria, viruses, fungi, and other microbes that play a crucial role in digestion, nutrient absorption, and immune function. A balanced intestinal flora is essential for maintaining overall health and preventing diseases. The composition of intestinal flora can be influenced by various factors, including diet, age, and lifestyle. A diet rich in fiber and probiotics can promote a healthy gut microbiome, while an unhealthy diet may lead to an imbalance. Disruptions in intestinal flora have been linked to conditions such as obesity, diabetes, and inflammatory bowel disease.
