QUOTE: ...Around 1971, someone noticed that the commercial cholesterol being used in feeding experiments was oxidized, that is, it wasn't really cholesterol. Comparing carefully prepared, unoxidized cholesterol with the oxidized degraded material, it was found that dietary cholesterol wasn't necessarily atherogenic (Vine, et al., 1998)... UNQUOTE.
