Gut microbiome needs time to adapt to fibermaxxing, experts warn 

Dr Megan Rossi explains that increasing dietary fibre feeds gut bacteria and promotes short-chain fatty acids (SCFAs) such as acetate, propionate and butyrate, which support gut, metabolic and immune health. Thomas Gurry of Myota adds that rapidly increasing fermentable or prebiotic fibre can increase microbial activity and gas production, potentially causing bloating and gastrointestinal discomfort while the gut microbiome adapts.
