Eating disorders and the zinc link
The idea that nutrient deficiencies could play a part in the development and treatment of eating disorders was first put forward in 1979. Of particular interest was the mineral zinc, as researchers noticed that the symptoms of anorexia and zinc deficiency were very similar in a number of respects. The symptoms of both zinc deficiency and anorexia for example include: loss of appetite, amenorrhoea, nausea, mal-absorption, weight loss, depression and anxiety.
Since that time, a number of double-blind trials have shown that those with anorexia are at a high risk of zinc deficiency and that zinc supplementation may be beneficial in treatment. Zinc supplementation has been shown to help decrease depression and anxiety and trials by Dr Carl Birmingham have demonstrated that the rate of increase in body mass of anorexics supplementing with zinc is greater than that of anorexics supplementing with a placebo.
These studies show the important role that nutrition plays in the treatment of eating disorders, and the importance of assessing the intake of micro-nutrients (vitamins and minerals) as well as the macro-nutrients (fats, proteins and carbohydrates) in restoring health.
