Objective
The current paper provides an analysis of the use of artificial sweeteners, caffeine, and excess fluids in patients diagnosed with anorexia nervosa.
Method
Seventy subjects with anorexia nervosa (AN) were recruited to participate in an ecologic momentary assessment study which included nutritional analysis using the Nutrition Data Systems for Research (NDS-R), a computer based dietary recall system.
Results
When subtypes were compared, AN-restricting subtype (AN-R) subjects and AN-Binge-Purge (AN-B/P) subjects did not differ in quantity of aspartame, caffeine, or water consumed. Daily water consumption was related to daily vomiting frequency in AN-B/P but not to daily exercise frequency in either AN-R or AN-B/P subjects.
Conclusion
Caffeine, water, and aspartame consumption can be variable in AN patients and the consumption of these substances appears to be only modestly related to purging behavior.
