Understanding Mayonnaise and the FODMAP Diet
The Low FODMAP (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) diet is a therapeutic elimination diet designed to identify food triggers for those with irritable bowel syndrome (IBS). A standard mayonnaise recipe includes egg yolks, oil, vinegar or lemon juice, and seasonings like salt. Since these core ingredients are naturally low in FODMAPs, a basic, unadulterated mayonnaise is generally considered safe. The primary risk comes from a variety of additional flavourings that manufacturers often include.
Navigating the Grocery Store: Checking Mayonnaise Labels
Not all mayonnaise is created equal when it comes to the low FODMAP diet. Commercial manufacturers frequently add extra ingredients to enhance flavour, which can introduce high-FODMAP elements. A few seconds spent reading the ingredient list is essential to avoid potential triggers.
Here are some of the most common high-FODMAP ingredients to look for:
- Garlic and Onion: These are major high-FODMAP culprits, and their powders or extracts are often added for seasoning.
- "Natural Flavours" or "Spices": If you see these ambiguous terms on the label, be cautious. They can sometimes be used to disguise the presence of garlic or onion. For absolute certainty, you may need to contact the manufacturer.
- Flavoured Mayos: Varieties like garlic mayo should be avoided outright, as they are specifically designed to include high-FODMAP ingredients.
- High-Fructose Corn Syrup: While less common in traditional mayo, it's always wise to check for sweeteners that could contain high levels of fructose.
Making Your Own Low-FODMAP Mayonnaise at Home
For complete control over your ingredients and peace of mind, making homemade mayonnaise is the safest bet. The process is straightforward, requires only a few standard kitchen tools, and ensures no hidden FODMAPs enter your diet. The basic components—egg yolk, neutral oil, and an acid like lemon juice or white wine vinegar—are all low-FODMAP.
A simple homemade recipe:
- Combine a room-temperature egg yolk, a conservative amount of low-FODMAP mustard (e.g., Dijon without garlic/onion powder), salt, and lemon juice in a jug.
- Using an immersion blender, add the neutral oil (like canola or avocado oil) in a slow, steady stream while blending continuously.
- Start by blending at the bottom until the mixture thickens, then gradually lift the blender to incorporate all the oil.
- Once emulsified, adjust seasoning to taste.

Conclusion: Making the Right Choice
When it comes to the question of can I eat mayonnaise on a FODMAP diet?, the answer is a resounding 'yes,' provided you choose wisely. For ultimate safety and flavour control, homemade mayonnaise is your best option. However, for those seeking convenience, numerous store-bought brands offer low-FODMAP versions. The key is to always read labels meticulously and be cautious of hidden garlic, onion, and ambiguous flavourings. With a little attention to detail, you can continue to enjoy creamy, delicious mayonnaise without the worry of triggering digestive symptoms.
