It's long been suspected that GMO foods could be toxic to humans (big huh duh), but very little real research has been published. The link below will send you to the abstract of a GM maize rat-feeding study done by Monsanto, results of which they have suppressed. There's also a PDF of the entire report available from other links, but it's over 1000 pages. If this link doesn't work for some reason, let me know and I'll post the abstract.
