However, there is currently no specific analysis of the flux profile of selenium intake and dietary health evaluation in tilapia. In addition, it is important for consumers to obtain relevant assessments of the selenium content in different species of tilapia. This will enable different age groups to plan their dietary intake in an organized manner accordingly. We counted the total import and export volume of tilapia in China. Furthermore, we modeled the distribution of selenium content based on the production mode on this basis. The study also delved into the distribution pattern of selenium content within China (n=147). Guangdong, as the production place of tilapia, is the largest e-commerce channel for consumers. The median selenium measured in frozen tilapia, pickled tilapia and canned tilapia was 0.233 mg/kg, 0.239 mg/kg and 1.073 mg/kg respectively. It is evident that adults globally should regulate their consumption of canned tilapia to avoid selenium toxicity. Furthermore, relying solely on tilapia consumption is insufficient to meet the selenium needs of infants. The findings underscore the nutritional value of tilapia in diets. Additionally, these insights can facilitate a comprehensive assessment of the health implications associated with dietary choices, enabling the formulation of targeted advice for various age groups worldwide.</div></div>","PeriodicalId":15867,"journal":{"name":"Journal of Food Composition and Analysis","volume":"137 ","pages":"Article 106916"},"PeriodicalIF":4.0,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
