Overview

Why eat firm tofu?

Firm tofu is a compact source of complete plant protein, with 21.76 g in a half-cup serving, plus a striking amount of calcium from the calcium sulfate used to set it. It is naturally low in sodium and carbohydrates, and its mild flavor takes on whatever seasoning or sauce you cook it with.

Good to know: Tofu itself is very low in sodium at 14 mg per 100 g, so most of the salt in a tofu dish comes from the marinade or sauce you add.

  1. Complete plant protein

    A half-cup serving delivers 21.76 g of protein (44% DV), supplying all the essential amino acids needed to build and maintain muscle and other tissue.

  2. Remarkable calcium content

    Set with calcium sulfate, this tofu provides 683 mg of calcium per 100 g, 53% of the Daily Value, supporting bone strength and normal nerve and muscle function.

  3. Minerals for energy and defense

    Per 100 g it supplies 32% DV selenium, 42% DV copper, 15% DV iron and 14% DV each of magnesium and zinc, minerals that support antioxidant enzymes and oxygen transport.
