Mixed

High consumption of plant-based foods (nuts, oily fish, fruit, vegetables, cereals) is associated with a higher abundance of short-chain fatty acid (SCFA)-producing commensals (e.g., Faecalibacterium prausnitzii, Roseburia hominis) and pathways for acetate/butyrate synthesis, which are linked to mucosal protection and anti-inflammatory effects.

Increase intake of nuts, oily fish, fruits, vegetables, and cereals. These foods feed beneficial bacteria that produce short-chain fatty acids, which protect the gut lining and reduce inflammation.

GoodSupportsHIGH confidence
Consumption of nuts, oily fish, fruit, vegetables and cereals is linked to a higher abundance of SCFA-producers... These bacteria are known to have anti-inflammatory effects and provide protection of the intestinal mucosa through fermentation of fibre and pectins to acetate and butyrate.
