The purpose of this study was to investigate how Registered Dietitians (RDs) have responded to messages about the pros and cons of using artificial sweeteners and if they are recommending them to patients. Specifically, this study examined the differences among RDs that either do or do not recommend artificial sweeteners and (1) personal consumption (2) degree held, (3) number of years as a RD, (4) working with diabetic patients, (5) working with obese patients, or (6) personal opinion of artificial sweetener's safety or effectiveness.

A convenience sample of 55 RDs who were members of the California Dietetic Association, Orange District, during the 2010–2011 fiscal year participated in this study. It was found that a majority of RDs recommend the use of artificial sweeteners to their patients. Results from chi-square show no significant difference in recommendations of artificial sweeteners.
