Sushi's generally considered a healthy food, even when it's been Americanized with a Super Soaker's worth of mayo. But to find out just how healthy, first we consulted a pro from the Sushi Chef Institute to give us the lowdown on the most popular rolls and their most common ingredients. Then we calculated the average number of calories in said rolls, using sites like CalorieKing and CalorieCount, plus the nutritional info from multiple restaurants that serve sushi. Since recipes vary so wildly from restaurant to restaurant (especially when the plates are painted with spirographs of spicy mayo), these are just approximations of the counts before they've been Kewpie'd to death. Here's the ranking -- get your soy sauce ready.
Cucumber, avocado, eel, eel sauce
Turns out eel is exactly as evil as Little Mermaid makes it look.
