Diet Ratings
Most commercial mayo is keto-compatible (0-1g net carbs per tablespoon) with high fat content, but quality varies. Check labels for added sugars and seed oils.
iSome keto practitioners avoid mayo due to seed oil content and prefer homemade versions with avocado oil or olive oil for better fat quality.
Traditional mayonnaise contains eggs, an animal product. While vegan mayo exists, standard mayo is not vegan.
Mayonnaise made with avocado oil or olive oil is acceptable in moderation; however, most commercial mayonnaise uses seed oils (soybean, canola). Homemade versions with paleo-approved oils are preferable.
iStrict paleo advocates avoid mayonnaise due to processing and typical seed oil content. However, some paleo practitioners accept homemade mayo with avocado or olive oil as a condiment.
Typically made with refined oils and eggs. Commercial versions are processed. Homemade versions with olive oil are more acceptable. Use sparingly.
iMediterranean regions, particularly Spain and Portugal, have traditional mayonnaise-like preparations (aioli) made with olive oil, which are more aligned with diet principles.
Typically made with eggs (approved) but vegetable oil base (plant-derived). Quality varies significantly; some use animal fats instead. Processed condiment.
iStrict carnivores and Lion Diet practitioners avoid due to plant oil content. Some practitioners accept high-quality versions made with animal fats or avocado oil, though avocado is still plant-derived.
Compliant mayo exists (eggs, oil, vinegar, salt) but most commercial versions contain added sugar, soy, or other additives. Must verify ingredients carefully.
iMelissa Urban acknowledges compliant mayo is possible, but community debate centers on whether most store-bought versions meet Whole30 standards. Homemade mayo is safer.
Mayonnaise is primarily oil and egg, but commercial versions often contain garlic, onion, or high-fructose corn syrup. Monash testing is limited. Homemade or garlic/onion-free versions are low-FODMAP; standard commercial versions often contain high-FODMAP ingredients.
iMonash University has not extensively tested commercial mayonnaise products. Clinical FODMAP practitioners recommend checking labels for garlic, onion, or high-fructose corn syrup. Homemade mayo without these ingredients is safe.
Mayonnaise is 80% oil with added egg yolks (cholesterol) and sodium (typically 90-200mg per tbsp). High in saturated fat and calories. DASH recommends avoiding high-fat condiments; vinegar-based alternatives preferred.
Standard mayonnaise is made with soybean oil (high omega-6). While it provides fat for Zone ratios, the inflammatory omega-6 profile is problematic. Olive oil-based mayo is preferable but still processed.
Conventional mayonnaise is made with soybean or canola oil (high omega-6) and eggs. While eggs provide choline and nutrients, the oil base is inflammatory. Avocado oil or olive oil-based mayonnaise is preferable. Portion control is important due to caloric density and omega-6 content.
iSome functional medicine practitioners argue that pastured egg yolks in mayo provide anti-inflammatory compounds (choline, lutein) that offset the oil concerns. However, mainstream anti-inflammatory guidance recommends limiting conventional mayo due to seed oil content.
Mayonnaise is 80-90% fat (mostly soybean oil) with 100 calories per tablespoon and minimal protein/fiber. High-fat condiments significantly worsen GLP-1 side effects. A standard serving (1-2 tbsp) on a sandwich or in a salad can trigger nausea, bloating, and reflux. Patients should use mustard, vinegar, or low-fat alternatives instead.
