What food do you guys normally take to keep you stocked, other than the local pubs special

I'm looking at more options on grub, but here's the catch, aside from emergency and first aid, I'm strictly LOW SUGAR, so the typical energy bars,chocolate, jelly babies is out of the question,
Secondly,due to my age and condition I find myself able to burn over 3000kcal a day and still come home with some weight loss,.... some may call me lucky but its a pain in the a** after a week on the trail.....
