Dietitian note

Soy protein isolate is a concentrated form of plant-based protein extracted from defatted soybean meal and commonly used to boost protein content in processed foods and supplements. It retains allergenic soy proteins that can provoke IgE-mediated responses in sensitive individuals. Avoidance is essential on a soy-free diet to prevent adverse allergic reactions and inadvertent exposure to soy allergens.
