Prebiotics are non-digestible dietary fibers that promote the growth and activity of beneficial bacteria in the gut. They serve as food for probiotics, supporting a healthy gut microbiome and enhancing digestive health. Consuming prebiotics can improve nutrient absorption and help regulate digestion. Additionally, prebiotics may boost the immune system, reduce inflammation, and contribute to mental health through the gut-brain axis. Foods rich in prebiotics include garlic, onions, asparagus, and bananas. Incorporating these into the diet can significantly benefit overall health and wellness.
