Based on what scientific fact do you state "there is no safe level of aluminum for a baby?" We all, including babies, contain aluminum. That's the problem: i can't agree to "there's stuff in there that should not be" based on an opinion.

This is exactly what I always see happen. Common sense tells me formaldehyde and aluminum = not good. It's not iron after all. I don't recall every seeing formaldehyde or aluminum nutrition supplement pills. Yet people will literally argue that formaldehyde is naturally occurring and exists in our bodies and that's supposed to fly "scientifically". We need to do better.

From Wikipedia:

> Formaldehyde and its adducts are ubiquitous in living organisms. It is formed in the metabolism of endogenous amino acids and is found in the bloodstream of humans and other primates at concentrations of approximately 0.1 millimolar.

Maybe "people will literally argue that formaldehyde is naturally occurring and exists in our bodies" because, you know, it's true?

Also considering that aluminum is the third most abundant element in the Earth's crust, I'd be very surprised if even ancient people didn't have some aluminum in their bodies. They could ingest more aluminum than we do simply by chewing on food with dirt.
