I've recently inherited an original (1960s, I think) Kenwood chef. Lucky me. Even luckier, it has all the original attachments (dough hook, meat grinder, etc). However, I read something online about how food that's come into contact with aluminium cookware has 'health issues'. Does anyone know about this (a quick google didn't reveal anything)? I don't want to give me/ my small DC metal poisoning (or whatever the 'health issue' is)!
