Thanks. He's my hero! My husband couldn't believe when I started baking, he loves sweets. He used to hide them and I told him he didn't have to do that, I have will power. Sometimes we'll be at a gathering and I'll choose something on the sweet tray and tell him to eat it for me. He doesn't like all the same things I used to like, but he'll eat it for me anyway or my mom will if she's there.
I know what you're talking about though about how hard it is to find things you can eat. I know two people who have too much iron in their system and have a hard time with various menus. I read food labels, I've got my husband doing that now so we can reduce the sodium in our diets. I bought a few gluten-free items to try them thinking they might be healthier than the other stuff, but honestly they seem more soggy tasting.
Restaurants are getting better in my city about offering "smart menus" so if people are trying to eat healthier they know what they're getting.
Nut allergies have to be one of the worst that I've come across.
