Ghost of Gluten-free

Torta de chile relleno. Oaxaca, Mexico. 

Or "How modern journalism works".

Keeping up with the scientific reports, I came across this link suggested by a popular science communication site. Dated 2 November 2015, it's a snarky blog post titled Millennials Seek New Ailment After Gluten Sensitivity Turns Out Not To Be Real - the gist of which is summarized in the first paragraph:

A new scientific study by the people who proved that gluten sensitivity is a definitely a thing has proved that gluten sensitivity is definitely not a thing.

Note the use of "new". Following the link, it leads to a ScieceAlert page dated 19 August 2015, which details a familiar shift of the issue from gluten to FODMAPs. Reaching the end of the article, we note that this was actually originally published in Business Insider on 16 May 2014. Which means that the journal article being cited as being published "last year" was relative to that date - indeed, it actually refers to the Gastroenterology paper published in Aug 2013.

So, like what was old is new again, thanks to the remix nature of internet reporting. Back then, the iPhone 5 was the hottest thing around.
