Is mayo FODMAP friendly? Navigating Nutrition for IBS

According to Monash University, a leading authority on the low FODMAP diet, plain mayonnaise is low FODMAP in servings up to two tablespoons. However, the crucial factor when considering if a product is truly safe is to scrutinize the ingredients list, as many commercial brands include high FODMAP additives like garlic or onion. This guide will help you understand if mayo is FODMAP friendly and what to look for when choosing or making your own.

Quick Summary

Mayonnaise is typically low FODMAP in standard serving sizes, but careful label-reading is essential to check for high FODMAP additions. Learn which ingredients to avoid, how to choose a safe brand, and find a recipe for homemade, gut-friendly mayonnaise.

Key Points

• Check the Label: Always read the ingredients list for store-bought mayo to avoid high FODMAP additives like garlic, onion, and "natural flavors".

• Serving Size is Key: Stick to a recommended serving size of up to 2 tablespoons (40 grams) to ensure the FODMAP content remains low.

• Classic Ingredients are Safe: The basic components of mayonnaise—egg yolks, oil, and vinegar or lemon juice—are inherently low FODMAP.

• Consider Homemade: Making your own mayonnaise at home gives you full control over the ingredients, guaranteeing it is FODMAP friendly.

• Look for Certified Brands: Some companies, like Fody Foods, produce explicitly low FODMAP certified mayonnaise, taking the guesswork out of label reading.

• Use Garlic-Infused Oil: To achieve a garlic flavor without the FODMAPs, use garlic-infused oil in homemade recipes or as a flavoring agent.

Understanding FODMAPs and Mayonnaise

FODMAPs are a group of short-chain carbohydrates that can cause digestive distress for individuals with Irritable Bowel Syndrome (IBS). The standard ingredients in a classic mayonnaise recipe—egg yolks, oil, and vinegar or lemon juice—are all low FODMAP. This means that the base of the condiment is typically safe for those on a low FODMAP diet. The challenge arises with commercially produced mayonnaises, which often contain extra ingredients for flavor, stability, or preservation.

The Label-Reading Litmus Test

To determine if a store-bought mayonnaise is FODMAP friendly, the ingredient label is your most important tool. You must look beyond the generic name and check for specific high FODMAP additives. These can be sneaky, sometimes hiding under vague terms like "spices" or "natural flavors".

High FODMAP Ingredients to Watch For:

• Garlic and Onion: This is the most common culprit. Many mayonnaise varieties contain onion powder or garlic powder for extra flavor. Flavored versions, such as garlic aioli, are almost always off-limits.
• High-Fructose Corn Syrup: While less common in mayo, some brands may use high-fructose corn syrup as a sweetener.
• Certain Spices and Natural Flavors: Unless specified, these terms can be a red flag. If you are uncertain about a product, it is best to contact the manufacturer directly to confirm that no high FODMAP ingredients are included.

Comparison of Mayonnaise Options

To simplify the decision-making process, here is a comparison table outlining different mayonnaise choices based on their FODMAP content and a few other considerations.

Making Your Own FODMAP Friendly Mayonnaise

For those who prefer complete control over their food, making your own mayonnaise is a simple and rewarding process. It guarantees that your condiment is free from any hidden FODMAPs and allows for flavor customization.

Simple Immersion Blender Mayonnaise Recipe:

• Ingredients:
  • 1 large pasteurized egg yolk (room temperature)
  • 1 tsp fresh lemon juice
  • 1/2 tsp Dijon mustard (ensure no garlic/onion on label)
  • 1/4 tsp salt
  • 3/4 cup neutral-flavored oil (e.g., canola, avocado)
• Instructions:
  1. Combine the egg yolk, mustard, salt, and half the lemon juice in a tall jar that the immersion blender can fit snugly into.
  2. Pour the oil on top of the other ingredients and let it settle for a minute.
  3. Place the head of the immersion blender at the bottom of the jar and turn it on. Blend without moving until the mixture emulsifies and begins to thicken.
  4. Slowly lift the blender up and down to incorporate the rest of the oil. Continue blending until the mayonnaise is thick and creamy.
  5. Add the remaining lemon juice and season with more salt to taste. Refrigerate in a sealed jar for up to a week.

Sourcing Low FODMAP Mayonnaise

If you don't have time to make your own, there are store-bought options that are explicitly low FODMAP or generally safe. Brands like Fody Foods specialize in low FODMAP products and offer certified mayonnaise. Other brands known for simple ingredient lists, such as Primal Kitchen or Sir Kensington's, also have low FODMAP-friendly options, but a careful label check is always necessary.

Conclusion

So, is mayo FODMAP friendly? The short answer is yes, but with a significant caveat. Traditional mayonnaise made from egg, oil, and vinegar is typically low FODMAP and safe for consumption in standard serving sizes of up to two tablespoons. However, the addition of common high FODMAP ingredients like garlic and onion in many commercial brands means that a simple label check is non-negotiable. By being diligent about reading ingredients, choosing certified products, or opting for a homemade version, those following a low FODMAP diet can confidently enjoy this versatile condiment without triggering their symptoms.

It is recommended to consult with a healthcare professional or registered dietitian before making dietary changes.

Additional Low FODMAP Considerations

• Serving Size Matters: Even low FODMAP foods can become high FODMAP if consumed in large quantities. The recommended serving for mayonnaise is 2 tablespoons (40 grams), according to Monash University.
• FODMAP Stacking: Be mindful of consuming multiple low FODMAP items containing the same type of fermentable carb in one meal, as this can lead to 'stacking' and potentially trigger symptoms.
• Flavor Boosts: To add safe flavor to your mayo, consider using a garlic-infused oil instead of garlic powder, or mix in some low FODMAP fresh herbs like chives or dill.

Following these guidelines will ensure you can enjoy mayonnaise safely while adhering to your low FODMAP plan.
