Exactly. There are studies to support that just about anything we put into our bodies is dangerous in the proper amount. I wouldn't worry about it. Especially since most aluminum items used in the food and drink industry are coated in some way (aluminum cans, for example, are internally coated).

I mean, my grandfather smoked a pipe and worked in painting with lead based paint, and he lived to the ripe old age of 95 where he died peacefully in his sleep. My father worked with asbestos pipe for 20 years, and he's still just fine....and those are items that are known to be extremely life threatening. If I worried about all the stuff that 'might' be dangerous, I might as well just crawl into a corner and die.
