Caution

Legume

Soy is a versatile legume that can be high or low in FODMAPs depending on its form and preparation, with products like firm tofu and soy sauce generally being low FODMAP.

What is Soy?

Soy is a legume native to East Asia, widely used in various forms including whole beans, processed foods, and as a derivative in many products. It is rich in protein and can be processed into soy milk, tofu, tempeh, and soy sauce. The FODMAP content in soy products varies; for example, firm tofu and tempeh are typically low in FODMAPs, while whole soybeans and certain soy milks may be high in FODMAPs due to their oligosaccharide content.
