We have a rider from Estonia who has made Ill multiple times by "healthy" us foods, not fast food. We're talking Olympian level fitness not some guy who considers walking to the pub exercise.

We basically have to cook all his food from scratch from stuff from Whole Foods, Sprouts etc and still have to watch what sort of BS is getting put in US versions of stuff he buys back home.
