Numerous observational studies have suggested that adherence to the Mediterranean diet, may have protective effects against OA. The abundance of antioxidants and anti-inflammatory compounds and omega-3 fatty acids, among the Mediterranean diet components is believed to contribute to its beneficial effects on OA. Research investigating the association between the Mediterranean diet and OA has shown promising results. Several observational studies have reported that adherence to the Mediterranean diet is associated with a reduced risk of developing OA and with lower severity of OA symptoms. Additionally, intervention studies have demonstrated improvements in pain, function, and quality of life among OA patients following a Mediterranean diet intervention. Furthermore, emerging evidence suggests potential mechanisms underlying the protective effects of the Mediterranean diet against OA, including its ability to reduce inflammation, oxidative stress, and cartilage degradation. However, further well-designed randomized controlled trials and mechanistic studies are needed to elucidate the precise mechanisms and establish causality. In conclusion, the Mediterranean diet appears to be a promising dietary approach for the prevention and management of OA.

The aim of the study was to explore the association of microbiota with epigenetic age acceleration (EAA) using the Mendelian randomization.</p><h3>Method</h3><p>The independent genetic instruments of gut microbiota were obtained from MiBioGen consortium and the Dutch Microbiome Project. EAA data were derived from genome-wide association study. To assess the causal relationship between gut microbiota and EAA, we applied four different methods of Mendelian Randomization (MR) analysis: the inverse variance weighted method (IVW), the MR-Egger regression, the weighted median analysis (WMA), and the weighted mode. Furthermore, sensitivity analyses were conducted to evaluate heterogeneity and horizontal pleiotropy.</p><h3>Results</h3><p>We identified potential causal associations between 12 bacterial taxa and EAA (<i>P</i><sub><i>IVW</i></sub> and <i>P</i><sub><i>WMA</i></sub> &lt; 0.05). Among them, species Holdemania_unclassified (OR: 1.31, 95% CI: 1.13–1.52, <i>P =</i> 0.0004) retained a strong positive association with GrimAge acceleration. Family Acidaminococcaceae (OR: 0.64, 95% CI: 0.44–0.93, <i>P =</i> 0.019) and family Clostridiaceae1 (OR: 0.69, 95% CI: 0.49–0.97 <i>P =</i> 0.031) were negative association with GrimAge acceleration. Reverse MR analyses indicated that EAA was associated with 6 bacterial taxa in IVW and WMA. Among them, a strong inverse association was found between Phenoage acceleration and genus Turicibacter (OR: 0.928, 95%CI: 0.888–0.971, <i>P</i><sub><i>IVW</i></sub> and <i>P</i><sub><i>WMA</i></sub> &lt; 0.001).</p><h3>Conclusion</h3><p>Our study implicates the potential causal effects of specific microbiota on EAA, potentially providing novel insights into the prevention aging through specific gut microbiota.</p></div>","PeriodicalId":7720,"journal":{"name":"Aging Clinical and Experimental Research","volume":"36 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40520-024-02877-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142737181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
