Taste linked to Anorexia

Posted Aug 26 2008 4:24pm
My niece Jenni sent me an interesting article from the Calgary Herald (4th October). It draws a link between taste and anorexia; biological reasons are becoming more and more evident as we learn about eating disorders. Here is the article.......

Taste linked to anorexia.

Eating disorders. a part of the brain that helps regulate taste might play a role in anorexia nervosa.

using MRI's, reaserchers at the university of california, san diego and the university of pittsburgh measured activity in the brains of 32 women, while the women tasted sugar and distilled water. half of the women had recovered from anorexia and half had never had the eating disorder.

the researchers found that the former anorexics had significantly less activity in the insular cortex and surrounding areas of the brain when tasting sugar than did the control group.

" we get hungar signals to go ahead and eat, and food is rewarding" says lead author dr. walter kaye, a professor of psychiatry at uc san diego and the university of pittsburgh. "it appears that people with anorexia may be getting different signals, we are begininng to understand that there are good biologic reasons why people may be vulnerable to developing anorexia and bulimia," kaye says.

the study is available online in the journal Neuropsychopharmacology.
