According to a new report in the journal Epidemiology, people who eat a gluten-free diet may actually be at higher risk for exposure to arsenic and mercury.
This is quite concerning considering the growing popularity of the gluten-free diet with a quarter of Americans having gone gluten-free in 2015. That was a 67% increase from 2013.
The cause for the increased risk for arsenic and mercury exposure, however, is not necessarily a result of the gluten-free diet itself. Instead, it appears to be due to the fact that many gluten-free products contain rice flour as a substitute for wheat. Rice has been known to bioaccumulate both arsenic and mercury, as well as other toxic heavy metals, from water, soil or fertilizers.
Maria Argos, an Assistant Professor of Epidemiology in the UIC School of Public Health, looked at data from the National Health and Nutrition Examination Survey in order to search for a link between toxic metals in blood and urine and the gluten-free diet.
Out of 7,471 people who completed survey, 73 were gluten-free. The results were that the people who were eating gluten-free had higher concentrations of mercury in their blood and arsenic in their urine. Arsenic levels were nearly twice as high for gluten-free dieters and mercury levels were 70% higher.
Argos said:
These results indicate that there could be unintended consequences of eating a gluten-free diet. But until we perform the studies to determine if there are corresponding health consequences that could be related to higher levels of exposure to arsenic and mercury by eating gluten-free, more research is needed before we can determine whether this diet poses a significant health risk.
