Understanding Mayonnaise and the Low FODMAP Diet
Following a low FODMAP diet requires meticulous attention to ingredient lists, as hidden sources of high FODMAPs can be found in many processed foods. While traditional mayonnaise—made simply from egg yolks, oil, vinegar, and seasonings—is typically low FODMAP, commercial brands can contain added ingredients that trigger digestive symptoms. The primary concerns are added onion or garlic, which are potent high FODMAP ingredients.
For a mayonnaise to be considered truly low FODMAP, especially during the strict elimination phase of the diet, its ingredients must be carefully scrutinized. The good news is that many commercially available mayonnaises are suitable, provided they avoid specific additives.
The Verdict on Duke's Light Mayonnaise
To determine if Duke's Light Mayonnaise is a low FODMAP option, we must break down its ingredients. The product's label is the definitive source of truth.
Here is a list of the ingredients typically found in Duke's Light Mayonnaise:
- Water
- Soybean Oil
- Modified Food Starch
- Egg Yolk
- Distilled and Cider Vinegar
- Salt
- Mustard Seed
- Natural Flavors
- Lemon Juice
- Xanthan Gum
- Beta Carotene (Color)
- Potassium Sorbate (Preservative)
- Calcium Disodium EDTA added to protect flavor
Based on this list, Duke's Light Mayonnaise appears to be a safe choice for those on a low FODMAP diet. The key takeaway is the absence of explicitly listed high FODMAP ingredients such as onion or garlic powder. However, the presence of "Natural Flavors" requires a cautionary note. While often harmless, this term can sometimes mask the inclusion of small, unspecified amounts of high FODMAP ingredients. Most low FODMAP experts suggest that if a certified low FODMAP version is available, it is the safest choice. For Duke's, since garlic and onion are not listed, it is a low-risk product, especially if you have completed the reintroduction phases of the diet.

Safely Incorporating Mayonnaise on a Low FODMAP Diet
For those just starting the elimination phase or who are very sensitive, exercising caution is always a good practice. Here's a breakdown of how to handle mayonnaise safely:
Check the Label Carefully
- Read every ingredient: High FODMAP ingredients like onion powder, garlic powder, or other vegetable powders should be avoided, especially at the top of the ingredient list.
- Beware of "Natural Flavors": This can sometimes include onion or garlic flavorings. If you are highly sensitive, contact the manufacturer or stick to certified products.
- Note the Order: Ingredients are listed by weight. If a questionable ingredient is at the very end, it might be present in trace amounts, though it is best to avoid it during the elimination phase.
Consider Low FODMAP Certified Brands
Several brands are specifically certified to be low FODMAP, offering peace of mind. Products from FODY Foods are certified and offer various flavors, including original and garlic-free options. Primal Kitchen and Sir Kensington's Classic are also frequently recommended by FODMAP dietitians as safe options.
Try Homemade Mayonnaise
Making your own mayonnaise is a simple and guaranteed way to control all ingredients. This ensures it is completely low FODMAP and free of any hidden additives.
- Recipe: Combine egg yolk, lemon juice or a low FODMAP vinegar, oil, and a touch of mustard. Simply blend until emulsified.
- Flavoring: Add herbs like dill or chives, or use garlic-infused oil to get a garlic flavor without the fructans.
Conclusion: Making an Informed Choice
Based on its ingredient list, Duke's Light Mayonnaise does not appear to contain any overt high FODMAP ingredients like onion or garlic powder, making it a low-risk option for many people on a low FODMAP diet. The primary point of caution is the ingredient "Natural Flavors," which, for those who are highly sensitive or in the initial elimination phase, may warrant sticking with a certified low FODMAP brand. For those who have successfully re-introduced foods and know their tolerance levels, Duke's is likely a safe and convenient choice.
