There is no substitute for professional medical and nutritional advice. Here are some recommendations to professionals that I have first hand experience of.
Joanne Crovini is a very approachable and knowledgeable Nutritional Therapist, based in the Cardiff area. Check out her website here.
Dr Jens Rohrbeck is an Ecological Medicine practitioner, and runs a GAPS diet support group in Bristol. Check out his website here.
Check out the Institute for Functional Medicine website for a handy database of registered Functional Medicine practitioners near you.
More to come soon!
