Hi there! Taiwanese here.
We invented boba (full of sugar and unhealthy), and our cuisine, while delicious, can be incredibly unhealthy. We are actually struggling to confront one of Asia's largest obesity epidemics. I think the notion that we're an island "full of thin people who eat rice or noodles at almost every meal" is not only a problematic and reductionist characterization, it ignores the problems that we face (an epidemic of obesity and an aging population.)
