Prebiotics

Definition

Prebiotics are non-digestible fibers that feed beneficial bacteria in your gut, supporting a healthy digestive system.

Scientific / Technical Definition

Prebiotics are a category of dietary fibers that resist human digestion but are fermented by the gut microbiota, promoting the growth of beneficial bacteria such as bifidobacteria and lactobacilli. This fermentation process produces short-chain fatty acids that contribute to gut health and overall well-being.

Benefits

• Support the growth of beneficial gut bacteria
• Enhance digestive health
• Improve immune function
• May aid in mental health by influencing the gut-brain axis
• Help with mineral absorption, such as calcium and magnesium

Examples

• Chicory root
• Garlic
• Onions
• Asparagus
• Bananas
• Artichokes
• Leeks

Additional Information

• Effects: Prebiotics influence the gut-brain axis by modulating the composition and activity of the intestinal microbiota, thereby potentially affecting mental health and cognitive functions.
