Actually, Carrot, you were never on an “incredibly strict no sugar diet” as you wrote, not if you were eating rice, rice cakes and ordinary crackers. Even if you were ingesting some sort of all-bran crackers, brown rice and brown rice cakes, you were still putting sugar in your body, just more slowly than you would have with white rice.
Brown rice is a starch, and it turns into sugar once it is broken down by your system.
I’m curious about what type of oatmeal you were eating. Most likely, this was also being converted into sugar once in your system.
I certainly hope that the Candida sufferers on the forum will resist taking your advice to heart; with even a somewhat mild case of Candida, your diet would add months to their treatment period and suffering.
