How does the fiber in peas support the immune system regarding gut health?
Answer
It serves as a substrate for gut bacteria to produce short-chain fatty acids
Dietary fiber is essential for maintaining a healthy microbiome, which is closely linked to immune function. When fiber is consumed, it serves as a critical fuel source or substrate for the beneficial bacteria living in the gut. These bacteria then ferment the fiber to produce short-chain fatty acids. These fatty acids play a direct and significant role in modulating the immune system, helping to regulate inflammatory responses throughout the body.
