Yes. However, you can safely consume tempeh on a low FODMAP diet as long as you stay within a certain range. For example, the 8-ounce pack of tempeh that this recipe calls for comes out to 226 grams. To ensure that you stay within the safe range, you need to keep your servings to three. This will make sure that each person gets a total of ~75 grams, well within the acceptable range. Please note that some people may be able to tolerate larger amounts of FODMAPs. But it’s also important to consider the additional food items that you’re eating with this sauce. It pays to know the FODMAP levels of your stir fry and any sides, as it can make a difference in triggering your IBS symptoms.
