The purpose of this study was to analyze the trend of dietary lifestyle-related research articles during the period from 1990 to 2009. A total of 44 articles were identified and subjected to content analysis. Article content was coded according to subject of study, age of respondents, sample size, type of sample, statistical methods used and location of study. The most important type of content category was the study subject, and this was subdivided into research related to 1) dietary pattern, 2) health, 3) dining spaces, 4) foods, 5) restaurant/institutional foodservices, and 6) beverage-related topics. The most common subject was restaurant/institutional foodservice-related research (59.1% of articles), followed by beverage-related research (20.5%). These two subjects accounted for approximately 80% of all the 44 articles reviewed.
