We have a _lot_ of studies and evidence that says coffee reduces overall mortality by quite a bit, and it holds for both caffeinated and decaf coffee. It seems like coffee specifically reduces the risk of Alzheimer's as well.

That result is almost certainly bullshit, at least for Alzheimer's. Or the effect is so minimal that it doesn't practically matter.

Why? Because Finland is the country that consumes the most coffee per capita in the world. Finland also has the highest amount of Alzheimer patients per capita. Correlation is not causation, but based on this, it should rather be suspected that coffee causes Alzheimer's rather than helps with it.

Could Finland's high incidence of Alz also have to do with its high latitude and Finlanders' lack of Vitamin D?
