One of the things I had heard about aluminum was cooking acidic foods in them, like cooking homemade spaghetti sauce in a cast aluminum pot.
But who knows? The ones who create some of these taxpayer-paid 'studies' often have some axe to grind, and the ones who deny them have their money invested in producing the materials.
And, of course, most studies (esp with health and medicine) focus on a teeny-tiny facet of something, and totally ignore how the substance fits into the whole picture.
