Diet may help reduce cognitive decline

So they are aware of the possibility of this effect, yet didn’t bother with it. Sounds like replication crisis to me.

Cheese is by far the most protective factor to prevent Alzheimer’s later in life?

How can a dietary study predict what helps later in life? Aren’t there too many external factors to really give these results any weight?

Ask participants about 24 things and you are bound to find correlations that have no actual basis in fact for that sample size. They might have well have asked about their favorite colors and music while they were at it. This is an obviously bad study funded by industries that are not impartial, and really has no business being posted here.

Seems like a whole host of other lifestyle factors were completely ignored.

Mice are really into cheese - hence become a mouse to avoid Alzheimer's later in life.

That’s not what the replication crisis is; replication crisis is more like 20 groups doing experiments that have a 1/20 chance of success if the effect wasn’t real, the one who got the positive result publishing it, the 19 who didn’t keeping quiet about it, and nobody else bothering to replicate the experiment with the one success to see if it was real or fluke.

What you’re quoting is more of “follow up studies will look at this”.

When doing simple questionnaire based studies like this, it should be standard practice to ask a few purposefully ridiculous control questions. Ask them which brand wine they like. What's their favorite color, sports team and grocery store chain.
