Tempeh Vs Tofu: Understanding the Basics

What Is Tempeh?

Tempeh originates from Indonesia and is a popular soybean product in many Asian countries. It is made by fermenting cooked soybeans, which binds them into a compact, cake-like form. The fermentation process makes tempeh easier to digest, reduces the negative effects of phytic acid, and provides a good source of prebiotics for a healthy gut 1. Additionally, tempeh is high in protein, fiber, and various nutrients. As a soy-based food, tempeh does contain plant hormones called phytoestrogens, specifically isoflavones 2. These are known to have weak estrogenic effects on the body.

What Is Tofu?

Tofu, also known as bean curd, is a versatile soybean product originating from China. It is made by coagulating soy milk and pressing the curds into a soft, easy-to-use block. Tofu is an excellent source of protein, low in calories, and contains bone-building calcium. It does not have as much fiber or as many nutrients as tempeh; however, it provides a smoother texture and different culinary uses. Like tempeh, tofu is high in isoflavones, which are phytoestrogens, producing a weak estrogenic effect in the body 3.
