The low-FODMAP diet isn't meant to be a life-long diet, as it excludes a lot of healthy and nutritious ingredients that are important to eat as part of a balanced diet.
The low-FODMAP diet is beneficial as it can help you to reduce symptoms when you get started, but long term, we would recommend using your FoodMarble device to help identify foods that contain certain FODMAPs that might be problematic for you so that you can discover your particular tolerance for that food.
