Does extra virgin olive oil prevent Alzheimer’s disease?

12 Jan

Sound too good to be true? It probably is. Here is a post on the topic by Joy Victory:

To deconstruct how this went off the rails, let’s start with the university news release sent to journalists: “Temple study: Extra-virgin olive oil preserves memory & protects brain against Alzheimer’s.”

That’s a headline that surely got journalists’ attention. It’s not until after two very long opening paragraphs extolling the virtues of the nearly magical powers of extra virgin olive oil that we find out who, exactly this was tested on.

Mice.

Andrew Gelman gives his take:

I looked briefly at the published research article and am concerned about forking paths, type M errors, and type S errors. Put briefly, I doubt such strong results would show up in a replication of this study.
