From a cooking point of view, if you chop up celery small, the texture can mimic nuts. I use it in jello mold sometimes to stretch the nuts, which I can’t eat a lot of due to diverticulitis.
I always wonder about fennel, which I grew up eating in an Italian household. It’s very much like celery, but tastes like licorice and (it figures, because I like it) is more expensive. I wonder if it has the same health benefits.
I have diverticulitis also. A recent finding is that nuts (especially walnuts and almonds) and corn do not aggrevate the diverticuli. Small seeds are far more dangerous, like seesame seeds, tomato or cucumber seeds, or sunflower seeds. Pumpkin seeds however are supposedly good substitutes for sunflower seeds. I eat loads of salted Almonds. BP is average to low and my diverticuli don’t act up. I find eating too much ice cream is my worst assault on my diverticuli. So I’ve started to make icebox pies from Instant pudding mixes using vanilla yogurt instead of milk (two packages of white chocolate and cheesecake to 3 1/2 cups vanilla lo-fat yogurt), and topping with cool-whip lite and peanut butter blended together. Yummy for the tummy!
