House Call: The potential dangers of a gluten-free diet

“The question we all need to ask ourselves is, why eat a gluten-free diet?” said Dr. Seth Sullivan from Baylor Scott & White Health.

Sullivan is referencing new research from the Mayo Clinic that suggests eating a gluten-free diet can lead to ingesting more heavy metals instead, like cadmium or arsenic.

“It’s not reaching fully toxic levels yet, but it’s getting close,” said Sullivan. "It's still concerning."

Sullivan notes that plenty of people eating gluten-free are doing so because of Celiac disease, a condition that doesn’t allow the body to digest gluten properly.

“For those people, unfortunately, there’s no solution to this potential problem just yet,” Sullivan said. "But for people making a choice, this might be a reason to re-evaluate or talk to a doctor."
