Sushi & Roll Calorie Calculator
Calculate the caloric impact of your sushi order. Differentiates between traditional sashimi and calorie-dense Western rolls (tempura, mayo).
About
Sushi is often perceived as a diet food, but the caloric gap between traditional Japanese sushi and Westernized rolls is vast. A single piece of Nigiri averages 40-50 calories, while a "Specialty Roll" laden with cream cheese, tempura flakes, and spicy mayo can exceed 500 calories per roll. This calculator provides a reality check by breaking down the components.
The tool accounts for the hidden density of vinegared rice and sauces. Spicy mayo alone adds approximately 100 calories per ounce. By selecting specific rolls or building a custom order, users can visualize how quickly a "light" meal accumulates energy, primarily from carbohydrates and fats in modern fusion rolls.
Formulas
The total caloric content Etotal is the summation of individual pieces P and full rolls R.
Rice density is a key variable; standard sushi rice contains approx. 1.3 kcal/g due to the vinegar/sugar seasoning, which is higher than plain steamed rice.
