answer:It’s certainly not proven. Aluminum is not particularly good for the brain, but it has a very hard time getting past the blood/brain barrier when consumed in food. Canned beverages can actually develop some harmful properties when stored at high temperatures, which actually revert to normal when returned to a lower temperature. It has nothing to do with why other products are in glass containers, they are in glass containers because they always have been, since long before aluminum was used. Some people also think certain products taste better from glass. But if you are concerned about aluminum, the first thing I’d do is stop using antiperspirant, especially aerosol.
