This study showed that higher-fat consumption byhealthy young adults whose diet is in a state of nutrition transition appearedto be associated with unfavourable changes in gut microbiota, faecalmetabolomic profiles and plasma proinflammatory factors, which might conferadverse consequences for long-term health outcomes.
