The article is all about quantity but not even one bit about if either quantity is, in fact, dangerous at either level. What’s the distance between the “safe” amount and the toxic amount? In a lot of cases there is an order of magnitude or two between the safe limit and the lowest level needed for a toxic effect.

I know this is targeted at people that can’t science but I feel it left out a “why are you even worried about aluminum in the first place” bit.
