Every time this topic comes up, only aluminum foil, aluminum pans and aluminum adjuvants in (((vaxxines))) come up. The biggest source of potential aluminum consumption in our lives is aluminum cans from sodas, juices and beer. Sure the cans are lined with a plastic material to prevent direct contact of the contents with aluminum can itself, but that is not a perfect barrier to acidic drinks or cans that have been around for a while. Until some study that isn't jewed can link higher incidences of dementia or autism to drinking out of aluminum cans, I think it's difficult to say aluminum is the main cause of dementia. We won't get such a study, but I think the number of beer drinkers with dementia would be high if aluminum was indeed the smoking gun. I'm not saying aluminum doesn't play a part in dementia development, but I don't think we know enough here to say for sure it does or doesn't. Also, that plastic liner in the cans, does that play a part in other health issues? I have not seen any concerns about the can or the lining so perhaps we're not looking at the situation properly. More work needs to be done in this area as well as all other sources of (((adulterated))) products we consume.
