I've always thought I'd like to visit Japan someday, but have always been worried about the cultural significance and omnipresence of white rice. Like, I can see how not eating rice would seem boorish (like you only want to eat the more expensive proteins, don't understand the purpose of a palate cleanser, etc), but living with type 1 diabetes I have not eaten white rice in literal years. Every single time I do, I regret it -- it's a complete nightmare to control your blood sugar after, sometimes for the entire rest of the day. I've even wondered if I could find a way to avoid being impolite by deliberately under eating the whole time if I were to visit, to make it clear I'm not just taking the good stuff and leaving the rice out of greed.
