where?
I'm Asian, my friends are all types of asians too from southeast asian to east asians, majority of the asian races and groups I know of, Chinese, Japanese, Koreans, Filipino(Largest consumer and importer of rice in the entire planet), Malay, Singaporeans, Indonesians all have rice for one as a staple.
"preferring bread" is different from constantly consuming rice
I Love burgers and pizzas, but I can't live without having rice in my system, that doesn't mean I have a rice fetish, it just means my system is too used to rice that there's something missing without it for long.
I've tried other culture's food staples, I think the closest one I could use as a substitute was my partners where she eats grits instead of rice
Potatoes are nice too but the amount of food you can pair it with is pretty limited also takes longer to cook and you can't just leave it alone to cook, you can leave rice alone to cook in a rice cooker and even without it the fire you need to maintain the warmth of the rice isn't much, i've tried both on a stove and on wood.
there's so much convenience that comes to just consuming rice that its hard to live without it
saves you on meat too since you can spread the meat sauces onto it and it becomes a part of the meal and that's plenty here in Asia considering how hard it is to earn a living, a mcdonalds worker in the US earns more than an office employee here if they just both started
