Not eating pre packaged chemical filled foods, simple sugars and gluten would be a great idea for now. You can still eat fruit that is low in sugar but forget fruit juice. If you take a probiotic and have good results then I wouldn't give it up. I personally prefer Kefir or my home made plain yogurt.

What I did initially with success was an alkalizing diet. After about a month I started to introduce other foods. Now what I do is try to balance each meal. For example, I really love my 1 cup of morning coffee (and yes, I use brown rice syrup which is sugar and half & half) so I will have a vegetable shake (Collards, cucumber, parsley, ginger, lemon, coconut milk and coconut oil) and maybe a hard boiled egg and then I can drink my coffee without a reaction. (Eggs can cause allergy problems for some people.)

I am not vegan. I eat as organic as possible and equally important I choose grass fed, free range products. I never eat low fat foods as the additives to make up for the fat taken out are horrible. I feel fat is extremely important for so many things and body functions but it has to be "good fat." I eat avocado, coconut butter, wild salmon or tuna and my home made full fat yogurt, etc.

I have no dx either. If you want more info just pm me.
