Unsurprising news

I love it when Science! backs up my prejudices:

Analyzing the data, Gibson found that each treatment diet, whether it included gluten or not, prompted subjects to report a worsening of gastrointestinal symptoms to similar degrees. Reported pain, bloating, nausea, and gas all increased over the baseline low-FODMAP diet. Even in the second experiment, when the placebo diet was identical to the baseline diet, subjects reported a worsening of symptoms! The data clearly indicated that a nocebo effect, the same reaction that prompts some people to get sick from wind turbines and wireless internet, was at work here. Patients reported gastrointestinal distress without any apparent physical cause. Gluten wasn’t the culprit; the cause was likely psychological. Participants expected the diets to make them sick, and so they did.

Self-diagnosis based on the advice of people named Oprah and Gwyneth is kind of a stupid idea when you think about it.
