Hello again vkw smile
I'm so sorry I haven't replied before now - don't know where the days get to sometimes.
I am happy to give out my email so you can write if you want to and I will share any help I can. As mentioned in another email a great site to look up information about food intolerances is that of Sue Dengate - www.fedupwithfoodadditivies.info/
My email address is kimeellis@bigpond.com so feel free to write anytime.
It is wise to check out intolerances/allergies when there are instances in the families - as you said maybe it could be the other side of the family, however sometimes people have a lot more intolerances than they know until they look a little more closely and its best to be sure. The research I have done all indicates that those with intolerances react not just to a certain food, but to the natural and artificial chemicals that the food contains. Some are higher in these things than others of course, but that is the theory.
Anyway, I hope to hear from you soon.
