Wow that's insane. Any examples in particular? I knew about some plant seeds that if eaten raw have toxins like canavanine that cause malformed proteins but wouldn't be obvious at first or (afaik) if you still overwhelmingly had enough protein in your diet... but getting your DNA completely shredded like that from a source other than radiation sounds so intense.

Destroying Angel and similar mushroom's have a toxin in it which kills some kind of rna enzyme needed for cell's to function properly. Not sure if it exactly fits the bill of DNA shredding but it'll give you irreversible organ failure in a matter of hours
