Let me put your mind at ease, You can not contract alzheimer's disease by using or burning aluminum foil.

Not to go into to much detail, but alzeimers can be contracted in part, and on very rare occations by cooking certain foods ie tomatos, and some but not all, acidic foods with certain older types of aluminum pans. This has to do with the chemical and molicular reaction between the two. Also note its not all acidic foods just some of them, and not all aluminum pans, & its not the only way to contract Alzeimers either.

Using foil in your bowl, (which I have used myself when i've run out of stainless steel or brass mesh), is safe. Aluminum foil and aluminum pans are different anyway both cemical and molicular and its 100% safe to cook all food types using Aluminum foil.

One would however heat the foil a little first to burn off the harmless residue coating thats on the surface of the foil, which is produced in the making of the foil. I also heat all my mesh a little before use, this is so it will burn off any residue on the mesh, as the residue just marrs the taste of the green.

Its just another urban myth, along with "you can not get cancer by smoking grass only", sorry folks but you can.

Anyway I think we can safely come to the conclusion that aluminum foil is a close 3rd choice as what to put in your bowl, but what would be your 1st choice, (brass or stainless steel) and why?
