This Low-FODMAP plan is gluten-free and dairy-free. Following this plan may help improve symptoms of IBS and other gastrointestinal issues. The plan is 28 days of following a Low FODMAP meal plan with an additional 28 days for reintroducing high and medium FODMAP foods to test for intolerances. Recipes include smoothies made with a gluten-free plain vegan protein powder. Protein powder should be based on brown rice, quinoa, or lactose-free dairy (whey). Pea protein along with artificial sweeteners and Inulins are high FODMAPs. Select a protein powder that is free of these and preferrably certified FODMAP friendly.
