i,m sure that your son will be better ,i do the diet it helps me 70% since last year ,but still take medication. i tried the medication alone ,it is not effective alone .so far i combine ,and hope the diet would be my only way to control my AS.
for the starch ,your son still can get his energy ,from glucose and fructose in fruits or dried fruits.

Good luck


no starch diet is way to go
