Default Diacetyl linked to Alzheimer's ?

That is what I take from this article.

I don't eat butter or butter flavored stuff, so hopefully I have negated my risks.

Three things:

1- They don't specify exposure levels other than Chronic factory exposure which I assume to be relatively extreme
2- Diacetyl is formed in beer, but is also readily reabsorbed by yeast. It has a low flavor threshold and is generally an off flavor, so there is likely very little in beer (comparatively)
3- While the study found an association between chronic diacetyl exposure and certain brain protein processes, it did not prove a cause-and-effect relationship

So I think that if you brew butter popcorn beer 8 hours a day for 20 years you might have a problem, maybe.

Pretty much probably standard meat. Whatever it is its somewhere lurking, legal and available for consumption. They know: we dont. Thats how they want it.
