  • Turns out that "gluten sensitivity" you have - may be a figment of your imagination.

  • Hey guys, Tara here for Dnews - to talk about one of the most popular trends in the world

  • right now - the gluten-free diet!

  • Now you've probably seen this video that went viral a few weeks ago. It features late night

  • talk show host Jimmy Kimmel asking a bunch of self-described gluten-free people on the

  • street, what gluten actually is - and no one seems to know the answer. It's a funny video,

  • but it also highlights the ignorance surrounding the gluten-free trend.

  • Now before we get into this, it should be noted that celiac disease - which is an autoimmune

  • disorder triggered by the consumption of gluten - is very much real. No one is trying to deny

  • that. Science has unequivocally proven it.

  • But the problem arises, when people who don't have celiac disease - attribute their problems

  • to gluten. Which is happening more and more, and especially here in America.

  • The gluten-free trend has been around for a while, but it exploded in 2011 - when a

  • professor at The Alfred Hospital in Melbourne, Australia - published a study linking gluten

  • to gastrointestinal distress in patients without celiac disease.

  • Well now, three years later, the same professor has stepped out again, with an even more rigorous

  • study - that appears to debunk his original findings.

  • In the second study, they looked at 37 patients with self-reported gluten sensitivities but

  • who were confirmed to not have celiac disease. They provided patients with every single meal

  • for the duration of the trial - so they could be sure to eliminate any and all potential

  • dietary triggers. First, they fed them a baseline diet, that was low in FODMAPs - which are

  • short-chain carbohydrates that are poorly absorbed in the lower intestine. They then

  • separated the patients into three groups - some with high-gluten diets, some with low-gluten

  • diets, and some with gluten-free diets. None of the patients knew which diet they were

  • eating - yet somehow, all of them reported a worsening of gastrointestinal symptoms over

  • the course of the trial.

  • So, they repeated the study. And this time, they had patients on either a high-gluten

  • diet, a gluten-free diet, or the baseline diet - which is low in FODMAPs. And STILL,

  • almost all of the patients continued to report an increase in symptoms.

  • This means that gluten couldn't possibly be the culprit - leading researchers to believe

  • that the real cause is psychological. Patients expected the diets to make them sick, so they

  • did.

  • Interestingly, almost all of the subjects reported an improvement in symptoms when they

  • were fed the low-FODMAP diet - making that a much more likely cause of distress, than

  • gluten.

  • It just so happens that FODMAPs occur mostly in bread products - which would explain why

  • people who eliminate gluten from their diets - and thus, bread - might see a reduction

  • in symptoms. Either way, this study effectively negates

  • the existence of non-celiac gluten sensitivity - and reminds us that the gluten-free trend

  • that's become so popular the past few years - has been primarily driven by consumer and

  • commercial interests, NOT scientific research.

  • What do you guys think? Is the gluten-free trend dumb? It's kinda hard to argue with

  • evidence like this, but I still wanna hear your opinions. So leave em in the comments

  • below - and as always, thanks for watching.

Turns out that "gluten sensitivity" you have - may be a figment of your imagination.
