It's non-toxic and food safe, and yet a significant number of people on the internet still act like it's poison that will give you Alzheimer's. I wonder how many of those people touch their lips to the lid of an aluminum beverage can. Or how they might bake a lasagna at home.
i heard aluminum food containers are often coated with toxic liners, like plastics, bpa, and pfas. If Alzheimers isnt a risk with pure aluminum metal, id say those liners are a huge risk. Are kitchen foils coated? Im pretty sure cans are most of the time.
I've only seen people concerned with it in antiperspirants, where it's a salt. (And to be clear, I think it's BS.)
As with NaCl, it's at least possible that the salt and the pure-ish variant aren't quite the same thing.
You shouldn't use aluminum foil with tomato/lemon/vinegar/brined foods or as "grilling packets" (direct fire/high heat) because of leaching risk.
There's no concern with using aluminum in most cases (with dry/non-acidic foods) but leaching is a real problem with acidic/salty/wet/high eat.
