Sadly it is a well known fact that journalists and bored research scientists sometimes end up in the pub together on a Friday afternoon. Which is when they make up stuff like this. It goes something like this:
[Journalists] We'll buy the next round if you can link curry to Alzheimers.
[Scientists] One of our rats once ate some poppadom that fell into its cage after a late-night sesh. And it didn't die from dementia.
[Journalists] That'll do nicely. Ta. What're you having?
The following week they all meet up for another piss-up and try to invent stuff that reverses the advice that they published the week before. They find it hilarious.
