Wow, thanks for all of the replies, makes for some interesting reading
Classic mayo is dairy free, but some mayos do have dairy - bizarrely, some of the reduced fat mayos have cream added
Thanks Six that explains it then & gives me more faith in the Dietician - we never buy low fat stuff, as I personally find it's usually full of rubbish & mostly a waste of time, so hadn't thought to check those - though she never mentioned low fat stuff, just insisted Mayo contained diary
& yes, it's an NHS Dietician - rough few weeks, so I was having trouble word finding & made a mistake
& if it is dairy, it's CMP, not lactose intolerance,
though I'm still not sure, as when I asked how the actual tests worked, eg: would it make difference to the blood test results that DD would not have any dairy & very little wheat in her system as I'd taken her off it when her stomach started to play up a few weeks earlier - I always take her off hard to digest foods with an IBS flare as realised a long time ago that it helps things settle down again. - I got different answers from different doctors
though both insisting DD would have it in her system, even though I knew she hadn't eaten any in over 3 weeks
Would anyone know how the lgE blood tests work ?? - do they add CMP to the blood to get a reaction ? Or does it only show up if she's eaten it more recently ??
Got to admit I'm more inclined to think it's egg - we were struggling to find food in the hospital - they weren't providing anything she could eat , so I was hitting the cafe salad bar & they had hard boiled eggs, which DD had a real fancy for & ate much more of those than usual - she gets egg in some form for breakfast every school day too - but hospital have insisted that she cuts out only the soy & dairy until we get the rest of the results back -
coping okay - bar when she had her picky eater friend stay over at the weekend - I usually just give in & give them pizza & veggie hotdogs with carrots & fruit, as it's all the friend will eat that's non meat & suddenly realising where they hide all the whey & soy - eek
I'm really missing soy more than dairy though, not been able to use soy sauce, terriaki etc has really made a dent in our favourite recipe list
Shame the Dietician is right as regards all milk products though - DD is missing cheese, when well she snacks on it quite a lot, though more low lactose stuff & a bit of buffalo Mozzeralla or feta would have made it easier:(
