As a registered dietitian, and member of the IBS club with a personal interest in gut health nutrition, I know it can be difficult to find plant-based recipes that are also low FODMAP. Which is why I’m committed to creating more vegan low FODMAP recipes here on the blog, as well as in my upcoming gut health cookbook, Good for Your Gut.

So let’s talk vegan low FODMAP snacks, shall we?

Even though the low FODMAP diet is only meant to be a short term elimination, when you’re plant-based, it can be a bit difficult to navigate because many plant foods like grains, legumes and nuts are higher in FODMAPs. But armed with vegan low FODMAP foods and a few good recipes, like these low FODMAP granola bars, it will help to make your low FODMAP elimination a LOT easier – and tastier!

List of Low FODMAP Nuts

On a plant-based diet, it can be tricky navigating low FODMAP because so many nutritious plants are high in FODMAPs, including nuts. Here is a quick list of low FODMAP nut servings and remember, FODMAPs are dose-sensitive! If you eat more than the listed serving, it may be too high in FODMAPs.

  • 10 almonds
  • 10 Brazil nuts (I do not recommend eating more than 2-3 Brazil nuts a day due to high selenium)
  • 10 roasted chestnuts
  • 10 hazelnuts
  • 20 macadamia nuts
  • 32 peanuts
  • 10 pecan halves
  • 10 walnut halves

Low FODMAP Granola bars storage, tips + serving suggestions

  • To ensure that the bars are crisp, not crumbly, make sure the mixture is VERY well mixed (use your hands if you need to) and press firmly into the pan. You also want to make sure that once you cut them, you let them cool completely before handling.
  • If your nut butter is dry, your bars will be dry. Go ahead and add a tablespoon or two of oil if you think you need it.
  • The low FODMAP serving size is 1-2 granola bars...but they’re filling so that’s all you’ll need!
  • These bars will keep well, loosely covered, on the counter for 3-4 days or you can freeze them for up to one month. They’re a great vegan low FODMAP meal prep recipe!
  • Enjoy these bars as an on-the-go breakfast with an almond milk latte or as a snack at any time of day.
  • The bars are super kid friendly. Need a nut-free school-friendly option? I have NOT tested this yet, but 1/2 cup of sunflower seed butter might work as a nut free AND low FODMAP option as long as you don’t go over a 1 bar serving.
  • You could even crumble them up and enjoy them as a granola with some unsweetened coconut yogurt and a few berries.

For Peanut + Ginger Bars, add

  • ¼ cup salted peanuts, chopped
  • ¼ cup crystallized ginger, diced

For Pumpkin + Cranberry Bars, add


  • Preheat oven to 350°Fahrenheit (175°C) and prepare a 9×9 square baking dish with parchment for easy removal.
  • In a medium bowl, whisk together peanut butter, maple syrup and vanilla.
  • Add oats, flax, hemp, cinnamon and salt and mix very well with a fork. The oats should seem well-coated with liquid. If the mixture seems, dry, knead with your hands! Then add your mix-ins: either peanuts + ginger OR pumpkin seeds + cranberries and fold in.
  • Using wet hands, press mixture firmly and evenly into baking sheet. If it starts to stick, rinse hands and press again.
  • Bake for 30 minutes, until granola bars are golden brown at edges. Let cool for 10 minutes, carefully lift out of baking pan and cut into 12 bars. Let cool completely before serving as warm bars will be soft.


Don’t have a square baking dish? You can freeform these on a baking sheet, into a more rustic 9×9 square.
