How does carbohydrate quality affect gut microbiota diversity and overall health?

Carbohydrate quality affects gut microbiota diversity and overall health by influencing the types of fibers and sugars that reach the colon. High-quality carbohydrates, such as those from whole grains, fruits, and vegetables, provide prebiotic fibers that promote the growth of beneficial gut bacteria. In contrast, low-quality carbohydrates, like refined sugars and processed foods, can lead to reduced microbial diversity and potentially disrupt gut health, impacting digestion and immune function.
