We were just discussing aluminum cans the other day. Here's what Blessed posted the other day just in case anyone puts some ridiculous provax reference to the amount of harmless aluminum and formaldehyde we ingest every day:
I also wanted to comment on the discussions comparing aluminum exposure from oral intake (cans, antacids...) with that from injection.
These two routes of administration cannot be compared head to head on ANY substrate, as bioavailablity and effects are completely different. Otherwise why would we need IV and IM medications? We'd just give pills for everything, no?
The number of substances which are harmless when taken enterically (through your GI tract) but harmful when taken via injection are legion. Starting with air, for one.
