RE: Discoloured tongue
Just had a look at McKeiths you are what you eat book (particularly interesting section on stools) and apparently the yellow at the back of my tongue mean i need to take care of my colon. And the white is lack of beneficial bacteria and a possible elevation of yeasts.
So i need to cut out some dairy, bye bye cheese :(. And drink some aloe vera juice for my bowels?!? anyone know what this tastes like?
