What is the main difference between prebiotics and probiotics?

The distinction between prebiotics and probiotics lies primarily in their functions and nature. Prebiotics are substances that serve as food for beneficial bacteria in the gut, helping to nourish and promote their growth. This process enhances gut health by supporting the balance of bacteria in the digestive system.

In contrast, probiotics are live microorganisms, typically beneficial bacteria, that provide health benefits when consumed in adequate amounts. They directly contribute to maintaining or restoring gut flora balance. Therefore, option C highlights the crucial role of prebiotics in nourishing these beneficial gut bacteria, which is what sets them apart from probiotics. This understanding is essential for anyone studying gut health and nutrition, as it underscores the importance of both prebiotics and probiotics in a balanced diet.
