Although the site claim that this bottle has a inner lining that
is resistant to fruit acid and isotonic drink, I still do not have
much faith in aluminium bottles. If the lining start to come off,
acidic drink will leach out the aluminium which when taken
regularly will accumulate in the body to cause alzhemer disease
later in life. As for the plastic bottles, just make sure it is not
used to contain high temperature oil soluble solution and you shall
be fine. Just my opinion based on what I have read. The stuff that
leaked out from the plastic has been implicated for a straight 40
years of steady drop in sperm count in male human species.
