Could those who opt for a diet in which gluten is absent end up deficient in various essential minerals? That is the implication of a recent analytical study that used laser-induced breakdown spectroscopy (LIBS) to quickly measure concentrations of ash, potassium, and magnesium in gluten free flour. There are good reasons for those with certain medical conditions, including coeliac disease to avoid entirely foods containing water-insoluble proteins from wheat and other grains known collectively as gluten. Individuals with such conditions must consider how they obtain a balanced diet on a daily basis. However, going "gluten-free" has also become something of a fashionable lifestyle lacking scientific evidence of any health benefits. Those who choose to avoid gluten for such reasons may be unaware of the problems of mineral deficiency that might arise.
