I suppose the proof is how you feel. How do you feel whilst on the fruit smoothie ? I sure would like to think that I could also consume this kind of food at some point in the future.
The conclusion that one can arrive at if alkalising your body is the prime tool you are using to counteract the effects of fruit sugar, is that you could eat anything you like with Sugar whether simple or complex as your blood ph being alkaline would prevent any symptoms. I'm not sure this is the best protocol to be honest, as the candida will always try and multiply when the fruit Sugar is consumed as it gives it the opportunity to "hang on in there", however it will be inhibited at some point in the future due to the alkaline ph level of your blood. It would appear to me that you ought to be experiencing a bit of a merry go around of ups and downs...
How do you feel after the smoothies ? Have you got full control of the candida yet ?
If we could simply contain candida in its tracks by creating a slightly alkaline blood ph, then we could simply eat whatever we choose and just support our diet with very alkaline supplements.
