Jake... undigested carbs on the tongue... well, duh!!! They haven't gone through the entire digestive system, yet, it only starts in the mouth. If you can scrape it off, good for you!
I do have a problem with people saying that because they don't have thrush, other people don't. You can't scrape off what's on my tongue without taking my tongue along with it, so obviously it isn't like yours. So much for being "almost positive" that "candida isn't causing our problems." Also, what is coming out of me is not undigested food, and looks NOTHING like the food I am eating.
We have enough crap from doctors, we don't need it on a SUPPORT forum. Perhaps your post could go in the debate forum.
