My vitamin D level is probably fine since I take cod liver oil almost every day. NY is north of the equator BTW.

I've been avoiding anything with any grain (except for rice or quinoa that I've prepared myself), I haven't even used soy sauce in the past two weeks, but I'm not sure about cross-contamination. Is it a problem if my kid eats some cookies and then takes a sip of water from my glass, and then I continue to use that glass? Could a tiny amount of airborne wheat flour gotten from the mixing bowl where the kids are making cake, to the mixing bowl where I'm making almond cupcakes? What if there's a trace of flour left on a measuring spoon?

I anyway blew the whole wheat-free thing today when there was cake on the table staring at me. I didn't eat much, about 1/4 of a normal slice, but from a gluten perspective I definitely messed it up. From a carb perspective the portion size made it OK.
