I Eat Mainly 15 Bean (redhill) Legumes Included With Tomato

I eat mainly 15 bean (redhill) legumes included with tomato sauce and hamhock which we cook for several hours in a crockpot. I am an 81 yr old diabetic and this is on my diet. I have just returned home from the hospital and being diagnosed as having Diverticulitis. I know that I can no longer eat Sunflower seeds, but what else am I unable to eat?
