Dietary fiber modulates gut microbiota composition and function, leading to the production of short-chain fatty acids (SCFAs) which improve glucose and lipid metabolism in individuals with metabolic diseases.
Increase your intake of diverse dietary fibers, particularly soluble and fermentable types like beta-glucan, inulin, and resistant starch. These fibers feed beneficial gut bacteria that produce short-chain fatty acids (SCFAs), which help regulate blood sugar and fat metabolism. Focus on whole plant foods rather than isolated supplements for best results, and introduce fiber gradually to minimize digestive discomfort.
Dietary fibre consumption has been hypothesised to reverse these changes through microbial fermentation and the subsequent production of short-chain fatty acids (SCFA), which improves glucose and lipid parameters in individuals who harbour diseases associated with dysfunctional metabolism.
Why this rating
The paper is a review citing numerous human intervention studies and meta-analyses, providing strong evidence for the general mechanism, though specific fiber types show variable results.
