The verdict
vegan mayo is the better everyday choice. It uses less land and water and carries a smaller carbon footprint than mayonnaise, while covering the same role on the plate. If protein density is your priority, adjust portion size rather than going back to mayonnaise.

In depth
The longer answer
Vegan mayo and traditional mayonnaise are both creamy emulsions used as spreads, dips, and bases for dressings. The key difference lies in the binder: traditional mayo uses egg yolks, while vegan versions replace them with plant-based emulsifiers like soy protein, aquafaba (chickpea brine), or modified starches. People compare them because they want a convincing egg-free alternative that doesn't sacrifice texture or taste, especially for those with allergies, dietary preferences, or ethical concerns about eggs.
Nutritionally, vegan mayo often has less saturated fat and no cholesterol, since eggs are the primary source of both in traditional mayo. However, both are high in total fat and calories, typically from oil. The environmental footprint of vegan mayo is generally lower because egg production requires significant feed, water, and land, and generates greenhouse gases. Plant-based emulsifiers have a smaller impact, though the oil source (e.g., soybean vs. sunflower) also matters. The mechanism is straightforward: replacing animal ingredients reduces resource intensity.
In real life, the choice depends on priorities. For baking or rich, eggy flavor, traditional mayo may be irreplaceable. But for everyday sandwiches, dips, or salads, many vegan mayos perform nearly identically—some even win blind taste tests. Price can be higher for premium vegan brands, but store-brand versions are often competitive. Texture varies: some are thicker, others looser. If you're cooking for a mixed group, vegan mayo is a safe, inclusive option that rarely disappoints.

In practice
What this means for you
- Check the label for added sugar or starches, which some vegan mayos use to mimic egg texture.
- For a neutral taste, choose an aquafaba-based vegan mayo; for richness, look for one with mustard or vinegar.
- Store vegan mayo in the fridge after opening, just like regular mayo, to prevent spoilage.
- Use vegan mayo in coleslaw or potato salad—it holds up well and won't separate.
