Hello Steve from Downunder.
I am also one of the many thousands (?) who are following your current trial with interest. Initially I was extremely attracted to having raw foods in my day to day diet when you began and also had "cravings" for more fruit because of your blog
I confess though that it didn't really last as a solid effort on my part to "go raw". My fridge nevertheless looks VERY healthy with all the fresh produce I am purchasing recently though *grin*
A quick thought in regard to your itchiness. Many fruits and even a lot of vegie contain Salicylates which is a naturally occuring chemical similar to the pain killer "Aspirin". Some people can develop sensitivities to this and also Amines - another food chemical.
One of the most significant symptoms of Salicylate intolerance in people is itching and urticaria. I suffered severe bouts of this when I was on a medication for glaucoma once and had to eat a very restrictive diet. Thankfully its much much more manageable now since changing my medication
here is a wikipedia entry re
Salicylate Sensitivity for your interest.
