Mike - know others are going to pop in here, but, for some persons trying the diet, they need longer than 3.5 months. Remember reading of 9 months before good effects felt! In addition, did you use the iodine method to test for the starches? Carrots are starchy... You need to start with testing *all foods - at least that is the recommendation. Also, raisins. Need to be organic raisins, and ensure not 'preserved' with palm oil (a usual), and also nitrates and for some brands a whole lot more. These two could be upsetting the apple cart.
Hope that you can solve the whys of this and hope it is just, for you, a longer process to see NSD working effectively.
