The multicenter “Early-versus-Late-Parenteral-Nutrition-in-the-Pediatric-Intensive-Care-Unit” randomized controlled trial (PEPaNIC-RCT) addressed whether this association is causal. It showed that early supplementation of insufficient/contraindicated enteral nutrition with parenteral nutrition, as compared with accepting a macronutrient deficit throughout the first week in the PICU, did not improve outcome. On the contrary, it caused more infections and prolonged organ support and PICU stay, and adversely affected neurodevelopmental outcomes 2 and 4 years later.

These findings corroborated results from large-scale adult RCTs.

White meat, unprocessed, and processed red meat intakes were associated with 36, 14, and 322 microbiota species, respectively. Species associated with processed red meat were enriched for bacterial pathways like amino acid degradation, while those negatively linked were enriched for pathways like homoacetogenesis. Furthermore, species positively associated with processed red meat were to a large extent associated with reduced trimethylamine N-oxide and glutamine levels but increased creatine and carnitine metabolites, fasting insulin and glucose, C-reactive protein, apolipoprotein A1, and triglyceride levels and higher blood pressure.</div></div><div><h3>Conclusion</h3><div>This largest to date population-based study on meat and gut microbiota suggests that meat intake, particularly processed red meat, may modify the gut microbiota composition, functional capacity, and health-related biomarkers.</div></div>","PeriodicalId":10517,"journal":{"name":"Clinical nutrition","volume":"45 ","pages":"Pages 124-133"},"PeriodicalIF":6.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142969911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
