Are you gluten-free? According to Cleveland Clinic Wellness, you should be aware:

Preliminary research suggests people on gluten-free diets may be at increased risk of exposure to arsenic and mercury, toxic metals that can harm your health. In the study, those who reported following a gluten-free diet had much higher levels of arsenic and mercury in their bodies than those who didn’t follow a GF diet.

The item notes that more research is needed, but that these findings are in keeping with other research on rice, the most popular gluten-free grain. So it’s a good idea to vary the grains you eat, and not rely on rice all the time. Try quinoa, gluten-free oats, teff, and millet.
