I have been under the impression since university that sushi is a healthier option for a meal, and the most popular sushi option in North America is the California roll.
> California roll (加州巻き,カリフォルニアロール, kariforunia rōru) or California maki is an uramaki (inside-out makizushi roll) containing imitation crab (or rarely real crab), avocado, and cucumber. Sometimes crab salad is substituted for the crab stick, and often the outer layer of rice is sprinkled with toasted sesame seeds or roe (such as tobiko from flying fish).
> As one of the most popular styles of sushi in Canada and the United States, the California roll has been influential in sushi's global popularity, and in inspiring sushi chefs around the world to create non-traditional fusion cuisine.[2]

That seems misguided. Sushi is just, very loosely, "thing on vinegared rice". If you put unhealthy thing on rice, it's still an unhealthy thing. May as well say "sandwiches are a healthy food" or "salads are healthy food".
