Net-carb calculation: total carbohydrate - fiber
The public USDA record was transcribed September 6, 2026 with 100 g selected. It describes raw regular tofu prepared with calcium sulfate, not low-fat soy flour (the former FDC 172444 mapping), and not every firm, extra-firm or silken product. The evidence file is a partial public-page transcription, not a complete API response. Energy and carbohydrate are calculated; no unobserved analytical derivations are assigned. Use the product label for a different texture, coagulant or formulation.

WHY IT'S KETO-FRIENDLY
- Calculate the ingredient amount using the stated preparation and weight.
- The net-carbohydrate value comes from total carbohydrate minus fiber in the same reference.
- Oil, coatings and sauces contribute their own nutrients and do not subtract carbohydrate from this ingredient.

Texture labels do not establish one universal nutrient ranking; water content, coagulant and formulation differ.
HOW TO USE IT ON KETO
- Use the exact package’s prepared or drained serving basis.
- Record the ingredient weight before pressing or cooking, then record the final recipe yield if calculating the finished dish.
- Count marinades, oils and other ingredients separately; their nutrients are not included in this panel.
PREPARATION SUGGESTIONS
CHOOSE THE RECIPE’S TOFU TYPE
Use the texture specified by a tested recipe and follow the package’s storage and preparation instructions.
CALCULATE A TOFU BOWL
Measure tofu, vegetables, oil and sauce separately. Use the tofu product’s label when it differs from regular calcium-sulfate tofu.

TOFU ON KETO: FAQ
Which tofu does this nutrition panel describe?
Regular tofu prepared with calcium sulfate in the cited USDA record. Firm, extra-firm, silken, flavored and fried products need their own matching information.
Is extra-firm tofu always lowest in carbs?
No universal ranking is established here. Compare the exact labels on the same weight basis and account for the portion you plan to eat.
Does pressing tofu leave its per-100-g nutrition unchanged?
No. Removing water changes weight and can change nutrient concentration. Use a documented preparation and yield or a matching pressed-product label; do not assume a fixed carbohydrate deduction.
How much tofu can I include in a meal?
Use the portion calculator with the matching tofu reference, then include every other ingredient. This page does not prescribe a daily tofu allowance or guarantee ketosis.
