I’m sure you have encountered friends and acquaintances who are going ‘gluten-free.’ I have observed, I don’t think imagined, a certain smugness about the announcement. Like they have elevated themselves above the masses. Well, It turns out maybe not.
People who eat a gluten-free diet may be at risk for increased exposure to arsenic and mercury – toxic metals that can lead to cardiovascular disease, cancer and neurological effects, according to a report in the journal Epidemiology.
Gluten-free diets have become popular in the U.S., although less than 1 percent of Americans have been diagnosed with celiac disease – an out-of-control immune response to gluten, a protein found in wheat, rye and barley.
A gluten-free diet is recommended for people with celiac disease, but others often say they prefer eating gluten-free because it reduces inflammation – a claim that has not been scientifically proven. In 2015, one-quarter of Americans reported eating gluten-free, a 67 percent increase from 2013.
Gluten-free products often contain rice flour as a substitute for wheat. Rice is known to bioaccumulate certain toxic metals, including arsenic and mercury from fertilizers, soil, or water, but little is known about the health effects of diets high in rice content. (my emphasis)
