Selecting, storing & prepping mayonnaise
- Selecting
- Traditional mayonnaise is made from just oil, egg yolks, an acid like vinegar or lemon juice, and seasoning; light or reduced-fat versions replace some of the oil with water and thickeners, which changes both calorie content and texture.
- Storing
- Unopened mayonnaise keeps until the printed date in the pantry; once opened, it must be refrigerated and used within about 2 months for best quality and food safety.
- Prepping
- Because mayonnaise is an emulsion, whisking briefly before use redistributes any separation that can occur near the end of its shelf life.

Key metrics
Nutrient density
Per 100 kcal, mayonnaise delivers about 2% of a Daily Value on average across 22 beneficial nutrients. The score is its percentile for that measure among the 177 foods in our database — higher means more nutrition per calorie. How this is calculated.
Density counts protein, fiber, and vitamins and minerals (not fat, sodium, or sugar), each capped so a single nutrient can’t dominate, with a calorie floor so very-low-calorie foods aren’t overstated. It measures nutrition per calorie within our database — a useful guide, not a complete verdict on how “healthy” a food is.
