Before I get to the 'everyone' bit, let me mention people with severe celiac. This article, I think, is directed at people with extreme gluten intolerance that would have severe digestive issues even from trace amounts of gluten due to cross-contamination. So, you think, as its impossible to avoid, you have to take the drug? Look at this bit:
Since gluten is so common in food processing, it's almost impossible to avoid ingesting tiny amounts of gluten, even for people with celiac disease.
The key bit is 'food processing'. If you are primal/paleo, the main point is avoiding processed food. If you eat meat, vegetables, perhaps raw nuts & seeds, even dairy, from trusted sources, you will avoid gluten. Just avoid pre-packaged, pre-processed food, and you won't need to pop pills.
Now, the 'everyone' bit. So, people can continue eating gluten-containing food, as long as they take a pill to counteract the damage? That's like saying, its fine if we drink poison, as long as we drink the antidote straight after. Of course, wheat isn't arsenic, but the point still stands.
Perhaps you'll avoid the intestinal perforation from gluten, but you're still consuming a Neolithic Agent of Disease (NAD), with plenty of other negative side-effects besides the gluten content - what about the anti-nutrients in grain? And all those carbs (if you're an athlete, go bake a sweet potato.)? To add insult to injury, you're basically adding another NAD (chemicals from the medicine). Do you really need to ingest more chemicals and drugs, what with all the pollution and chemical contamination that goes on anyhow?
I hope this didn't come accross across as harsh, I don't mean it to, but I just found this rather absurd - not surprising though, since Big Pharma always gets out of its way to cure the symptoms without addressing the underlying cause, and allow people to continue poisoning themselves.
And continue staying away from grains. :-)
