Hi again!

If you were a severe diabetic would you still eat it? No. If you were an alcoholic and drinks were being served would you take one? No. I would say (IMHO) that the best thing to do would be to advise them of your specific dietary needs beforehand so that arrangements may be made, and if it is going to be too much trouble, then I would bring your own. Of course you may make something that others would enjoy too and share it with others, pot-luck style. Just as long as you let them know that it isn't their cooking that has turned you off!!

All the best!
