Min J, et al. - Investigators systematically examined Americans’ perceptions of fast food (FF; defined as their beliefs, attitudes, and knowledge) and how these perceptions might affect fast food consumption (FFC) and obesity risk. They searched PubMed and Google for studies published in English until February 17, 2017, that reported on Americans’ perceptions regarding FF as well as those on their relationships with FFC and obesity risk, of which 13 met inclusion criteria. According to findings, neither perceived availability of FF nor Geographical Information System-based FF presence in the neighborhood had significant correlations with weekly FFC. However, the researchers acknowledged that there was considerable variation in Americans’ perceptions of FF and how they might associate FFC with obesity risk.
