Probiotics vs. Prebiotics: What’s the Difference and Why Does It Matter?

2. Prebiotics: Nourishing the Good Guys

Prebiotics are non-digestible food components, primarily fibers and oligosaccharides, that selectively stimulate the growth and activity of beneficial bacteria in the gut. Unlike probiotics, prebiotics are not live organisms but rather the food source that fuels the growth of these beneficial microbes. Common sources of prebiotics include garlic, onions, bananas, and whole grains. By providing nourishment to beneficial bacteria, prebiotics help maintain a healthy gut microbiome balance, supporting digestive health and enhancing the body's immune response. Additionally, they play a role in the production of short-chain fatty acids (SCFAs), which have anti-inflammatory properties and contribute to overall gut health. The effectiveness of prebiotics depends on factors such as the type of fiber, dosage, and individual gut microbiota composition.
