Breakdown for 1 cup
Is soya beans (dried, boiled, drained) low FODMAP?
GOS becomes amber at 31 g, and the 210 g portion is red for both GOS and fructans. Turning soybeans into a different product changes the food being assessed. Tofu, fermented soy foods, soy drinks and soy-based meat substitutes therefore need their own entries rather than the whole-bean portion figures.
Soya Beans (Dried, Boiled, Drained) and IBS: what to know
If your food diary simply says soy, it can be hard to compare a meal containing boiled soybeans with one containing a processed soy product. Record the whole-bean preparation and the amount, using the 27 g green portion as a reference. The rating describes this food at that serving; it does not predict every person's response or rate the rest of the meal.
Gut-friendly ways to eat soya beans (dried, boiled, drained)
Cook dried soya beans according to their packet directions and drain them before weighing. Add a measured serving to rice or a vegetable dish, keeping the beans separate until their portion is set. Do not substitute the same weight of a soy-based mince or a seasoned soybean snack and assume the rating carries over.
Frequently asked questions
Are soybeans and soya beans the same food here?
Yes. This page uses both names for the dried beans prepared by boiling and draining. It does not cover all ingredients whose labels mention soy.
Is a small soybean portion weighed before cooking?
The 27 g reference is weighed after the soya beans are cooked and drained. Measuring that amount from a dry packet does not match the app's preparation.
Do these ratings apply to tofu or soy drinks?
No. Those are distinct soy products with their own processing and composition. The 27 g whole-soybean serving is not an allowance for a tofu dish or a drink.
