What's the other 58%?

OK, I haven't blogged in ages because I've been busy, looking after baby, too tired to blog ...blah blah blah. You know how it is.

Anyway, I read this article this evening and I was moved to blog. Ignoring all the tax-stuff in the article, what surprised me is that Pringles are only 42% potatoes! What else is in Pringles for goodness sake? I knew it was processed but not that processed. From now on I'm sticking to Kettle chips.
