Are Potatoes Low FODMAP?
A common question I often hear is, are potatoes low FODMAP? The answer is, yes! In most cases. Here is a little more information on potatoes + FODMAPS:
- White Potatoes are low FODMAP, in fact according to Monash University, no FODMAPs have been detected in white potatoes and typically can be eaten freely when following a low FODMAP diet.
- Sweet Potatoes have been found to be low FODMAP friendly in servings up to 1/2 cup. Over 1/2 cup servings, sweet potatoes have been found to contain the polyol mannitol in servings above 2/3 cup.

Are Mashed Potatoes Gluten Free?
Mashed potatoes are in fact gluten free because potatoes are naturally gluten free. Gluten is a protein found in wheat, barley + other grains and potatoes are not a grain, they are simply a starchy vegetable. Enjoying mashed potatoes on a gluten free or low FODMAP diet is absolutely possible!

Low FODMAP Mashed Potato Ingredient Swaps
- Milk + Butter: You can use dairy milk + grass fed butter, non-dairy milk + vegan butter, or a combination that suits your personal needs and preferences. Any combination will work in these low FODMAP mashed potatoes.
- Truffle Oil: While I highly suggest you do not omit the truffle oil from this recipe, you can absolutely use garlic infused olive oil in its place if your preferences are not for truffle.
Gut Health Tip: If you have difficulty digesting fiber, be sure to peel your potatoes prior to boiling. If you are looking to add fiber to your diet, leave the potato skins on. They contain loads of vitamins + minerals like vitamin B + C, iron, calcium + potassium!
