A fresh roll of sushi can be a flavourful and light meal. In some cases, however, it can be a diet-buster. Some California rolls are loaded with mayonnaise and dynamite rolls are made with battered and deep-fried shrimp. Imitation crab, found in most mall-variety California rolls, is high in carbs—and so is the white rice around it. Dipped in soy sauce, these sushi rolls aren’t much better than a fast-food meal. Choose fresh, sustainable sashimi instead, and order brown rice where possible.
