I just had an email from WebMD (no, I don't know how I got on their mailing list) which has a list of all the foods you're supposed to avoid during the holidays. As far as I can remember, they are:
Sweet potato casserole
All hors d'oeuvres
All mixed drinks
Buttery mashed potatoes
Cakes, cookies, and a special mention of pecan pie
I'm fascinated. Are there actually people who follow these rules during the holidays? (Except, obviously, in cases like severe diabetes and things like that.) And if there are, and you inadvertently invite them to a holiday party (well, you wouldn't do it on purpose, would you), what on earth do you DO with them while everyone is eating? Hand them a plate of raw celery and a glass of water?
