ABSTRACT
Objective To analyze the epidemiological evidence on the relationship between ultra-processed foods intake and metabolic syndrome. Methods CNKI, Wanfang database, PubMed and Web of Science Core Collection database were searched to obtain literature, as of June 10, 2020, about ultra-processed foods intake and metabolic syndrome. The relevant literature was reviewed and analyzed. Results A total of 4 epidemiological studies about the relationship between ultra-processed foods intake and metabolic syndrome were found, of which three studies suggested a positive correlation, and one study suggested no correlation. Conclusion There may be a positive correlation between ultra-processed foods intake and metabolic syndrome, but the research results available are still controversial. Further research is needed to explore the relationship between ultra-processed foods intake and metabolic syndrome.
