Not trying to nit pick but Beans and other foods are stored in stainless cans,not in aluminum and coke is one of the most unhealty drinks on this planet, so a bit aluminum will only complement this qualities. I really hope you dont boil things in those cans though.. or torch them with 1300 Flame.I've read numerous articles about smoking from aluminum cans and most of them say it is ok ,because there no data to prove it is harmful,lol... but most them also add this : ""With any good herb, flavor is important. Smoking from foils can give your herb a harsh, metallic taste, especially if you burn the foil. The fumes may not be seriously dangerous, but smokers have reported headaches and harsher coughs from it." For sure there is something happening and Howie already said it is all about RISK tolerans I am happy that you have decided not to worry about it ,it is probably best for one's mental health..,but "having already passed that" doesnt add to facts in anyway ,in my case i find more mental comfort by avoiding this particular type metal when it is applied in high heat concepts.
