Is Peanut Butter Low FODMAP?

Is Peanut Butter Low FODMAP?

Yes, peanut butter is low FODMAP! At a serving of 2 tablespoons (32-50g), peanut butter contains no detectable FODMAPs and is safe for people following a low FODMAP diet. This makes it an excellent source of protein, healthy fats, and energy for those with IBS.

Safe Serving Size

According to Monash University, peanut butter is low FODMAP at servings up to 2 tablespoons or 50 grams. Multiple brands have been tested, and all show no detectable FODMAPs at this serving size. Peanut butter is considered safe during all phases of the low FODMAP diet.

Important note: While peanut butter is low FODMAP, it is high in fat. Excessive fat intake can affect gut motility and may trigger symptoms in some people with IBS, even without FODMAPs present.

Why Is Peanut Butter Low FODMAP?

Unlike many other legumes, peanuts contain minimal oligosaccharides (GOS and fructans):

• Processing removes FODMAPs - The roasting and grinding process may reduce FODMAP content
• Naturally low - Peanuts have less GOS than beans, lentils, or chickpeas
• Oil content - Peanuts are high in oil, which dilutes any potential FODMAPs
• Well-tolerated - Most people with IBS can eat peanut butter without issues

Peanuts are technically legumes (not tree nuts), but they behave differently than other legumes when it comes to FODMAPs. While chickpeas, lentils, and black beans are high FODMAP, peanuts and peanut butter are safe.

Choosing the Right Peanut Butter

Not all peanut butters are created equal. Here’s what to look for:

Safe Low FODMAP Peanut Butter

✓ Natural peanut butter - Just peanuts and salt ✓ Smooth or crunchy - Both are low FODMAP ✓ No added sugars - Or use regular sugar (low FODMAP in small amounts) ✓ Organic options - If that’s your preference

High FODMAP Additions to Avoid

✗ Honey - High FODMAP at 1 tablespoon ✗ High fructose corn syrup - High FODMAP ✗ Inulin or chicory root - Often added as fiber, very high FODMAP ✗ Agave syrup - High FODMAP sweetener ✗ Dates or dried fruit - High FODMAP

Best Practice: Read ingredient labels carefully. Stick to natural peanut butter with just peanuts (and possibly salt) to ensure you’re avoiding hidden FODMAPs.

Peanut Butter Nutrition and Benefits

Peanut butter offers several nutritional benefits for those on a low FODMAP diet:

• Protein - About 7-8g per 2 tablespoons
• Healthy fats - Monounsaturated and polyunsaturated fats
• Fiber - About 2g per serving (can help with gut health)
• Vitamins and minerals - Vitamin E, magnesium, niacin, folate
• Energy - Around 180-200 calories per 2 tablespoons
• Satisfying - Helps keep you full between meals

For people with IBS who struggle to find safe protein sources, peanut butter is a convenient, shelf-stable option.

Tips for Eating Peanut Butter on Low FODMAP

• Measure your portions - Use measuring spoons to ensure you’re at 2 tablespoons
• Mind the fat - High-fat foods can slow digestion; some IBS sufferers are sensitive to this
• Check ingredients - Always read labels for high FODMAP additives
• Pair wisely - Combine with low FODMAP bread, rice cakes, or fruit
• Don’t overdo it - While low FODMAP, eating excessive amounts may cause discomfort due to fat content
• Store properly - Natural peanut butter needs refrigeration after opening

Peanut Butter vs. Other Nut Butters

How does peanut butter compare to other nut and seed butters?

Peanut butter has one of the more generous low FODMAP serving sizes compared to other nut butters, making it an excellent choice.

Peanut Butter Alternatives

If you need alternatives to peanut butter:

• Sunflower seed butter - Nut-free, low FODMAP at 2 tablespoons
• Macadamia nut butter - Creamy, low FODMAP at 2 tablespoons
• Tahini - Sesame seed paste, low FODMAP at 2 tablespoons
• Walnut butter - Low FODMAP at 2 tablespoons
• Almond butter - Low FODMAP at 1 tablespoon (smaller serving than peanut butter)

Peanuts vs. Peanut Butter

Both whole peanuts and peanut butter are low FODMAP:

• Whole peanuts - Low FODMAP at 2 tablespoons (about 32 peanuts)
• Peanut butter - Low FODMAP at 2 tablespoons
• Peanut flour - Check serving sizes, as concentrated products may differ

You can enjoy peanuts in various forms without worry during the low FODMAP diet.

High Fat Sensitivity

Even though peanut butter is low FODMAP, some people with IBS are sensitive to high-fat foods:

Signs of fat sensitivity:

• Diarrhea after eating fatty foods
• Stomach cramping
• Nausea
• Quick bowel movements after fatty meals

If you experience these symptoms, you may have bile acid malabsorption or fat malabsorption, which is different from FODMAP intolerance. In this case:

• Reduce portion sizes of peanut butter
• Choose powdered peanut butter (lower fat)
• Spread fat intake throughout the day
• Consult with a dietitian

The Bottom Line

Peanut butter is low FODMAP at 2 tablespoons (32-50g) and is a safe, nutritious choice for people with IBS following a low FODMAP diet. It provides protein, healthy fats, and energy without triggering FODMAP-related symptoms. Choose natural peanut butter without added honey, high fructose corn syrup, or inulin. Enjoy it on toast, in smoothies, with fruit, or in homemade low FODMAP peanut sauce. While low FODMAP, remember that peanut butter is high in fat, so some people with IBS may need to moderate their intake if they’re sensitive to fatty foods.
