Are these foods allowable on the No Grain Diet?

I'm about to start Dr Mercola's No Grain Diet, but am unsure about some allowed foods on the diet.

I searched the web for answers, including Mercola's own site and emailed them without respsonse. I'm guessing that he may no longer advocate this diet for some reason, as he seems to have removed most of the helpful information from his website (eg. recipes etc, as promised in the book). I would really appreciate someone's help with this! thanks :)

Are the following foods are acceptable on the diet?
-channa flour (indian chickpea flour used to make pancakes)
-spices
-xylitol as a sweetener (i react to honey and stevia)
-balsamic vinegar
-tamari (wheat free)

Thanks for your help!
Oceandevi :)
