Probably depends if you are low carbing. If you are not and consume wheaty carbs then you need to re think where you are going to get your carbs from and maybe change to oat based foods or other non wheat flour products.
This is something you really need to discuss with a Dietician as your diet may now not be suitable and will probably require adjustment. You will certainly have to avoid certain foods, which you may or may not already do.
I don't eat wheat and have found the best of the breads is called Genius - the brown one is quite pleasant! I only have 2 slices toasted in morning for breakfast[that may change now diagnosed T2]. Do not like any wheat free bread untoasted - also hopeless for sandwiches as it falls apart. If you allergic and not coeliac then you have to pay for bread and Genius is £2.89 a loaf so that discourages you from eating too much as you only want to buy one a week! In fact all wheat free food costs more than the wheat laden stuff.
DS make some crispbread which are not bad.
I get oatcakes sometimes but they can be bit dry but OK with some pate on.
For the odd biscuit - when you feel you need something - Morrisons do a Free From Raspberry Cookie and Tesco Free From Shortbread are about the best I have found [again they may now disappear from my diet!].
Sainsbury's are the best supermarket I have found for wheat free goods.
