Virtual Food Triggers Eating Disorder Stress

Virtual Food Triggers Eating Disorder Stress A new study discovers individuals with eating disorders have similar emotional responses when presented with virtual food as they do with real food.

In the investigation, scientists compared the responses of people with anorexia and bulimia, and a control group, to virtual and real-life snacks.

The finding that virtually presented food causes an emotional response may open new avenues for evaluation and therapy of eating disorders.

Alessandra Gorini from the Istituto Auxologico Italiano, Milan, Italy, worked with an international team of researchers to compare the effects of the exposure to real food, virtual food and photographs of food in a sample of patients affected by eating disorders.

She said, “Though preliminary, our data show that virtual stimuli are as effective as real ones, and more effective than static pictures, in generating emotional responses in eating disorder patients.”

The 10 anorexic, 10 bulimic and 10 control participants, all women, were initially shown a series of six real high-calorie foods placed on a table in front of them. Their heart rate and skin conductance, as well as their psychological stress were measured during the exposure.

This process was then repeated with a slideshow of the same foods, and a VR trip into a computer-generated diner where they could interact with the virtual version of the same six items.

The participants’ level of stress was statistically identical whether in virtual reality or real exposure.

Speaking about the results, Gorini said, “Since real and virtual exposure elicit a comparable level of stress, higher than the one elicited by static pictures, we may eventually see VR being used to screen, evaluate, and treat the emotional reactions provoked by specific stimuli in patients affected by different psychological disorders.”

The research is found in BioMed Central’s open access journal Annals of General Psychiatry.
