For individuals managing Irritable Bowel Syndrome (IBS) or other digestive sensitivities, navigating the low FODMAP diet can feel like a complex puzzle. The good news is that potatoes, a versatile and widely enjoyed food, can often be a safe and satisfying option. This article provides a comprehensive guide to understanding the FODMAP content of potatoes, offering clarity and practical advice for incorporating them into a gut-friendly diet.
Understanding FODMAPs
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, And Polyols - a collection of short-chain carbohydrates. While these compounds are naturally present in many foods and are harmless to most people, they can trigger digestive discomfort in sensitive individuals. In those with IBS, FODMAPs can ferment in the gut, leading to symptoms such as bloating, gas, abdominal pain, and changes in bowel movements. Research indicates that following a low FODMAP approach can provide symptom relief for up to 75% of people with IBS. The low FODMAP diet is a systematic approach to identifying personal triggers, not a permanent restriction.
Potato Varieties and FODMAP Content
Not all potatoes are created equal, both botanically and from a FODMAP perspective. Understanding the different varieties helps you make informed choices for your digestive comfort.
White Potatoes
Varieties like Russet, Idaho, and Yukon Gold are considered starchy potatoes, high in starch and low in moisture. Other white potatoes include red, yellow and purple varieties. White potatoes - whether they're russets, reds, or fingerlings - generally contain no detectable FODMAPs. Monash has listed white and purple unpeeled potatoes as being low FODMAP in serves of up to 500g per person. Given that there are no entries for different varieties of potatoes (such as Russet or Sebago) one would have to assume that these quantities apply to all of the white fleshed potato varietals. Excellent news for the potato lovers amongst us. FODMAP Friendly has an entry for white potatoes, listing GOS as the FODMAP they found in white potatoes. The current Monash University app entries (one for yellow, one for red potatoes) only show a Green Light low FODMAP serving, with no Yellow or Red Light amounts. The small print says that the food remains low FODMAP up to 500 g. That is over a pound.
Sweet Potatoes
Botanically speaking, sweet potatoes belong to the morning glory family, while regular potatoes are nightshades. Sweet potatoes contain mannitol, a polyol that can trigger symptoms in sensitive individuals. Orange sweet potatoes and purple sweet potatoes are low FODMAP in up to 149g serves. White sweet potatoes are low FODMAP in up to 139g serves. In 140g serves, they contain moderate amounts of fructans. Sweet potato vermicelli noodles are low FODMAP in serves of up to 500g per person. At ½ cup (75g), sweet potatoes are low in FODMAPs. Servings larger than 100g (⅔ cup) are considered to be moderate in FODMAPs. However, sweet potatoes can be enjoyed as part of a low FODMAP diet at the recommended serving size stated above.

Preparation and Cooking Methods
The way you prepare potatoes can influence their digestibility and impact on your gut.
Skin On or Off?
Keeping the skin on potatoes increases fiber content, which can be beneficial for some people with IBS but may be too much for others during flare-ups. Potato skins add fiber and nutrients, but they can be harder to digest during IBS flare-ups.
Cooking Techniques
Since white potatoes contain no FODMAPs, you can prepare them using virtually any cooking method. For those managing digestive sensitivities, it's recommended to start with gentler cooking methods like boiling or steaming. You can enjoy potatoes in various ways - baked, steamed, boiled, roasted, mashed, fried and grilled! Cooking methods themselves do not impact FODMAP content.
Storage Considerations
When selecting potatoes at the store, avoid any with green patches, sprouts, or soft spots. Green potatoes contain solanine, a compound that can cause digestive upset regardless of your FODMAP sensitivity. Refrigerated potatoes convert starches to sugars, affecting both taste and digestive properties. Proper storage extends potato life and maintains their low FODMAP status. It is recommended to store potatoes in a breathable bag or open container, checking weekly for any changes.
FODMAP Stacking and Portion Control
FODMAP stacking occurs when you consume multiple foods containing small amounts of FODMAPs that add up to a problematic total load. White potatoes present zero stacking risk. Sweet potatoes require more attention; at ½ cup (75g) per serving, they remain low FODMAP.

Smart Strategies
Mixing white and sweet potatoes in dishes like roasted vegetable medleys allows you to enjoy the flavor complexity of sweet potatoes while keeping FODMAP levels comfortable. Managing FODMAP stacking doesn't require complex calculations - just some smart meal planning strategies. When combining potatoes with other ingredients, consider the cumulative FODMAP load across your entire meal. For sweet potato lovers, try this stacking-smart approach: Use ⅓ cup sweet potato mixed with 1 cup white potato in dishes like hash or roasted vegetable medleys.

Potatoes in a Low FODMAP Diet: Practical Tips
- Embrace White Potatoes: Feel confident including white potatoes in your meals without worrying about FODMAPs.
- Portion Sweet Potatoes Mindfully: Stick to the recommended ½ cup serving size to minimize potential symptoms.
- Choose Simple Seasonings: Be mindful of high FODMAP seasonings like garlic and onion powder. Instead, use chives and scallion greens.
- Read Labels Carefully: When buying potato products like chips or bread, check the ingredient list for high FODMAP additives.
- Consider Resistant Starch: Cooling potatoes overnight after cooking can increase their resistant starch content, which acts as a prebiotic and supports gut health.
