Tofu calories: use the package style and preparation
The USDA reference on this page is regular raw tofu prepared with calcium sulfate at 76 calories per 100 grams. Silken, firm, extra-firm, super-firm, and tofu made with a different coagulant can have different water content and nutrition.
How to log a U.S. serving
In a U.S. grocery store, the package label is the best source for a branded block. Record the amount actually used after draining; pressing out water changes weight, so do not assume that every half-block is the same serving.
When to use another entry
Fried tofu, baked marinated tofu, tofu scramble, and restaurant dishes include more than plain tofu. Add oil, sauce, sweetener, vegetables, and other ingredients or calculate the complete recipe.
Frequently asked questions
How many calories are in regular tofu per 100g?
The cited USDA entry lists regular raw calcium-set tofu at about 76 calories per 100 grams.
Can I use that value for silken or extra-firm tofu?
Not as an exact match. Water content and formulation vary, so use the package label.
Does fried tofu use the same value as raw tofu?
No. Frying oil, marinades, and sauces must be included in the finished dish.
