I have heard that aluminum may be a contributing agent in causing Alzheimer\'s disease, and that if we drink from aluminum cans, that we get aluminum into our system from them. It seems like this would be pretty easy to test in a laboratory, whether or not there are aluminum particles in the contained beverage. But I have heard or read that the inside of the cans are coated with something. So is this just typical uninformed rumors from the Internets, or is there anything to it? Hate to sound rude, but I am not really interested in opinions, like Well I don\'t think they would sell them if... or Oh yes, I think you get lots of aluminum from it. I am only interested in facts, not gut feelings or opinions.I recently covered this in a materials science class I am taking. My professor is Dr. Han Choo. Most aluminum cans have a coating of epichorohydrin. This is not to keep out the aluminum from the drink, but rather it is meant to keep the drink from reacting with the can(many sodas can actually eat through metal). The reaction of the soda with the can ruins the taste which is obviously something soda companies do not want. Aluminum also does not cause Alzheimer\'s. The metal is considered poisonous in large quantities and the FDA restricts the amount that can be added to drugs, food, drink, etc., but scientific consensus states that there is no link between Alzheimer\'s disease and aluminum. As far as BPA(Bisphenol A) health concerns go, there is little evidence proving any real harm to adults. The problems are only seen in offspring of the rodents being tested with BPA. For the most part there is little concern about the negative results of BPA exposure. There has not been any clear links in humans yet either. Extensive testing is still being done and BPA might be marginally dangerous to infants, but I wouldn\'t worry about it too much. If you still wish to guard yourself against BPA you should be aware that BPA is used in almost all commercial plastics and can liners(bottles, canned food, food storage containers, etc.) not just in aluminum cans.As mentioned, there is a coating on the inside of the can that prevents the drink from coming into contact with the can. You won\'t be getting any aluminum, HOWEVER in that coating is a chemical called BPA. This chemical has been shown to affect the body\'s hormonal systems and can affect the birth of future children, even if one is not presently pregnant. It has recently been declared a toxic substance in Canada and other countries seem to be slowly following suit in declaring it as such. This chemical is used because it is cheap. Governments tend to be very hesitant banning things that are harmful if they affect the way corporations can make money. I try to avoid cans for this very reason. When you drink from them you\'ll be getting trace amounts of this chemical. Trace amounts over time add up in the body, especially with this chemical.It\'s a fact that the cola industry controls us through microchips floating in their drinksOther related question
