Copper

"Copper linked to Alzheimer's disease" says the BBC headline. The story says that while one study suggests copper might contribute to Alzheimer's, others suggest that it might help protect the brain. The headline is a trifle misleading... Technically protecting the brain is a kind of link too, but it strains the usual use of words.

By the way, does anybody remember when aluminum was the culprit, and we were all supposed to worry about our cookware?

Aluminum isn't terribly good for you, and while we need some copper that can be bad too. And maybe Alzheimer's has more than one cause. The phrase "second childhood" is a lot older than aluminum pots.
