gluten - free diet refers to a completely gluten free food, once in the United States. Although it is mainly used to treat patients with celiac disease and gluten allergy, it is also eaten by some stars and athletes as weight loss and fitness foods. According to foreign media reports, a recent study published in the Epidemiology (epidemiology) magazine found that the total removal of gluten from diet may lead to increased levels of arsenic and mercury in the body as time goes on.
among the 7471 people surveyed, only 1.2% reported that they were gluten free diets. A number of University and college researchers tested urine samples from 73 gluten free diets. This study tested the total urinary arsenic levels in urine samples, and determined arsenite, arsenate, monometharsic acid and two metharsic acid. After adjusting a series of factors (including dilution of urine biomarkers, age, race, and sex), the researchers found that the levels of arsenic in gluten free individuals were higher than those of normal levels, and their levels of blood mercury and urine cadmium were also higher.
researchers speculate that gluten - free dieters (rice usually instead of gluten - rich grains) may contain higher levels of toxic metals. These researchers believe that "new evidence" indicates that rice foods may contain "high levels of toxic metals".
