answer:I had read somewhere that when you are invited to someone’s house, you should not “require” them to cook anything specific, and if you have any restrictions you should eat something first, so you’re set and not starving. I know some will disagree and say that’s foolish because the host wants you to eat what she cooks. I don’t think there’s any rule written in stone about who is responsible for communicating. I know when I was on a low carb diet, I would just attend parties and deal with it on my own by eating what I wanted and not eating what I couldn’t. I think when you’re hosting a party, it’s nice enough and responsibility enough to plan a menu without thinking of 30 or so people and all of their requirements and restrictions. I have another friend who told me about her health issues, and she would go to parties and tell everyone about her health issues and why she couldn’t eat this and couldn’t eat that. I don’t think people really care to hear that stuff. I think you should keep it to yourself. Just my opinion.
