Hello, I am very grateful to have read the information on Sue Dengates research into the link between food and asthma. However, I have gone to Amazon to source the various books she has published and I'm a little surprised to discover that cookbook is 261euros on the german site and £161 on the uk site. Could this be correct? I would really like to get it but I just cannot afford theses prices. Has anybody read the books and would you recommend paying these prices? Many thanks in advance for any help. I have two asthmatic kids and I suspect that they are reacting to foods but my Paed won't listen and there's a language barrier.
