Do you have a favorite recipe adapted for a medical condition?

Whenever I have a family gathering,I try to find some recipes to adapt to whatever the latest medical conditions are in the extended family. We are all getting older so we have family members with diabetes, heart disease,allergies,vegans and some healthy but generally health conscious.

I am looking for recipes that you have adapted for any special needs that turn out good.It can be any type of recipe-salads,desserts, but especially breads/rolls.Sugar free cinnamon buns?  Hi Protein bread? High fiber muffins?  Share!
