Can fiber regulate inflammation?

Sources:

Yes, fiber can play a significant role in regulating inflammation. When dietary fiber is metabolized by gut bacteria, it produces short-chain fatty acids (SCFAs) like butyrate, acetate, and propionate. These SCFAs can provide signals to immune cells, which helps to regulate their function and attenuate inflammation. This interaction is crucial in maintaining a balanced immune response and preventing hyperinflammatory states that are linked to various diseases such as autoimmunity, metabolic disorders, asthma, and allergies 1.

Moreover, a lack of dietary fiber can lead to a deterioration of the microbiota, resulting in a hyperactive immune system and increased inflammation, which contributes to many age-related diseases and other health issues like heart disease 2. Fiber's role in regulating the gut microbiome and producing anti-inflammatory compounds underscores its importance in both daily and long-term health 3.

Gut Health

Justin and Rhonda discuss the importance of dietary fiber for gut bacteria and how it impacts the immune system in the gut and the rest of the body. They explain how short chain fatty acids provide signals to certain immune cells to regulate their function in a positive way and how lack of dietary fiber can lead to a hyperactive immune system.
