I'm not even sure this shouldn't go under "Not about food" based on some of the stuff they are eating.
But very good friends, who we used to cook with and share food with have gone macrobiotic. No more Thanksgiving feasts, although I think they did Tofurkey one year and might have found it inedible (as she indicated they went to Cracker Barrel afterwards).
Is there any way to cook that might accomodate our tastes (which are still spice and flavor oriented as well as protein centric) and theirs (which have included no cooking anything, only eating 'local', and a few other variations.) (And yes, they both have had some problems with thinning hair.)
