TeaLeaf: paranoid food aversions haha, thats a new one. reminds me of that muppet mark on Peep Show, when he goes on about people being allergic to gluten and peanuts.
no im not paranoid about BPA, ive consumed enough hot water from plastic bottles for it not to worry me too much. but guar gum is something i definitely cant handle.
i have serious gut dysfunction, im more concerned with things that cause immediate reactions than the unknown. and i put BPA into the unknown category. although as an ecology hiker i use non BPA water canisters simply because plastic tastes like crap after a while.
I don't know what else to call it. We have a dear friend who stays with us for weeks on end with multiple food "issues". For example, she's lactose intolerant (probably) - but would a tiny trace of lactose in something be an issue? I suspect not, but it's not a subject up for discussion. It's surprising what you'll find a trace of lactose in if you read the labels. When she stays - we eat 100% paleo. Suits me - I get to pig out on meat, veges, and fat for weeks on end. Yum - with a clear conscience.
For gut health, you might be interested in this interview with Professor Peter Gibson from Monash, which was aired on RNZ earlier in the year:

I thought at the introduction of the interview, that this was going to be the usual "expert - dispelling the myth of gluten intolerance". However, it's very interesting with regard to general gut health, "wellness", and other factors which perhaps don't get the media attention they deserve.
