I don't know about the UK but the books that I've found most helpful for a
Candida-balancing diet are:
The Complete Candida Yeast Guidebook by Jeanne Marie Martin
Breaking the Viscous Cycle: Intestinal Health Through Diet by Elaine Gloria
I've read a lot and these are the best. They're both excellent!
Best of luck,
