Textured Soy Protein
Serving sizes
Textured Soy Protein changes rating with portion size. These are the amounts tested in the literature behind our ratings.
- About 2g
- Larger portions
- Much larger portions
Textured soy protein is High FODMAP at a usual serving, though about 2g is low.
- At about 2g textured soy protein is low.
- Made from defatted soy flour, it keeps soy's GOS and Fructans, so larger portions are moderate and much larger portions are high.
Reach for firm tofu, where much of the GOS is pressed away with the liquid, when you want a soy protein for the main plate.
