Thank you to online reader Cat for your comment on “Is Roundup the Cause of ‘Gluten Intolerance’?”:
We also thought asbestos was perfectly safe. Lots of research said so—until people started getting sick and it was linked back to asbestos. Then lots of research said it wasn't safe after all. Just because current thought is to consider these chemicals "safe", based on the types of testing conducted thus far (often funded by the companies that make these chemicals themselves), doesn't mean they're actually safe.
Why do you think gluten intolerance has dramatically increased in the past two decades? Leave a follow-up comment.
