Mayonnaise
Mayonnaise is an emulsified condiment made from egg yolks, oil, and acid (vinegar or lemon juice). It is calorie-dense and high in omega-6 polyunsaturated fat, making portion awareness relevant for overall fat and energy intake.
Also known as: mayo, egg mayonnaise

Mayonnaise is a stable emulsion created by combining egg yolks with vegetable oil (commonly soybean, canola, or sunflower), vinegar or lemon juice, and salt. The lecithin in egg yolk acts as a natural emulsifier, allowing oil and water-based ingredients to remain suspended. The precise origin of mayonnaise is debated — it is variously attributed to French culinary tradition or to the Spanish port of Mahón — but it is now a global condiment used in sandwiches, salads, and prepared foods. Commercial varieties account for significant consumption across North America and Europe.
A 1-tablespoon serving (14 g) of standard mayonnaise contains approximately 94–100 calories and 10–11 g of fat. The fat profile is dominated by polyunsaturated fatty acids, primarily omega-6, with a smaller proportion of monounsaturated fat and roughly 1.5 g of saturated fat per tablespoon. Carbohydrate and protein content per serving are negligible. Eggs contribute choline and selenium. Mayonnaise is generally well tolerated; however, its high fat content can slow gastric emptying and contribute to a feeling of fullness, which may be relevant for those consuming it in larger amounts.
Fat Intake and Cardiovascular Considerations
Mayonnaise is not inherently harmful but is calorie- and fat-dense; typical serving sizes are small (1–2 tablespoons). Its omega-6 content is substantial relative to portion size. For individuals monitoring total fat or calorie intake, or those following a low-fat dietary pattern, portion awareness is important. There is no established evidence that mayonnaise itself negatively affects blood lipids when consumed in typical amounts within an overall balanced diet.
Allergies and Tolerability
Egg allergy is the primary concern; individuals with egg allergy must avoid standard mayonnaise. Vegan and egg-free alternatives are widely available. Soy-based mayonnaise may be relevant for those with soy sensitivity. Most people tolerate mayonnaise without adverse effects. Those with delayed gastric emptying or fat malabsorption may experience discomfort if consumed in large quantities.
Frequently Asked Questions
Is mayonnaise safe for people with egg allergies?
No. Standard mayonnaise contains egg yolk as its primary binder and must be avoided by those with egg allergy. Egg-free and vegan mayonnaise alternatives are available and should be clearly labeled. Always check ingredient lists and allergen declarations.
Does mayonnaise contain gluten?
Most standard mayonnaise does not contain gluten. However, some commercial brands may add thickeners or other ingredients that include gluten. Check the label or select certified gluten-free products if avoiding gluten.
How much mayonnaise is a typical serving?
A standard serving is 1 tablespoon (14 g), containing approximately 94–100 calories. Most people use 1–2 tablespoons per meal. Portion awareness is relevant primarily for total calorie and fat intake management rather than safety.
