The same professor (Peter Gibson) from Monash University, Melbourne, Australia, who in 2011 released a study that proved gluten sensitivity, now claims that it's all in your head.
The new study on gluten sensitivity released in 2014 show that there's no proof of such thing and that it's all a psychological matter.
It is not gluten that causes gastrointestinal distress, but rather the FODMAPs. And guess what... bread and its by products are the greatest source of FODMAPs and this is why people who remove bread from their diet feel immediate relief.
In the US only 1.8 millions people is affected by the celiac disease - in contrast to the 18 million who are actually consuming gluten-free foods. It's all about marketing, there's no science proof!
What are FODMAPs?
These are a group of small carbohydrate (sugar) molecules found in everyday foods. These short-chain carbohydrates are incompletely absorbed in the gastrointestinal tract and can be easily fermented by gut bacteria. These sugars also exert an osmotic effect, increasing fluid movement into the large bowel. The fermentation and osmosis caused by these undigested sugars are a cause of major IBS symptoms such as gas, pain, and diarrhea.
