Homemade mayonnaise is crafted with a handful of simple ingredients: Oil, lemon, eggs, mustard, and vinegar often come together to create this favorite spread. However, many people opt for the convenience of store-bought mayonnaise, which they typically store in the fridge. Although there are several healthier and cleaner versions of mayonnaise on the market, some options still contain preservatives, additives, sweeteners, and other unhealthy components. Let’s explore six of the least healthy mayonnaise brands that might be sitting in your fridge right now.
Miracle Whip

KraftHeinz firmly maintains that Miracle Whip is a dressing, not a mayonnaise, but for years, consumers have regarded it as a mayo-alternative or near-mayo. Miracle Whip Light is characterized by the company as a “mayo-like dressing” and features a long list of highly processed ingredients, including artificial sweeteners, thickeners, high fructose corn syrup, and more.
Hellmann’s Real Mayonnaise

Similar to Kraft, Hellmann’s Real Mayonnaise includes soybean oil (it’s worth noting that most popular mayonnaises use either soybean or canola oil). Health experts point out that soybean oil is rich in omega-6 fats, which can be detrimental to health when consumed excessively.
McCormick Mayonnaise

McCormick Mayonnaise contains soybean oil and added sugar, both red flag ingredients in mayonnaise. Additives like disodium (a chemical preservative) also point to a highly overprocessed product that should be enjoyed responsibly.
Kraft

Kraft also uses soybean oil as the main ingredient in its mayonnaise. Cage-free eggs are a positive ingredient here, but otherwise this, like many other popular mayos, is an ultraprocessed product that contains ingredients like calcium disodium. It’s actually better than the “healthier” Kraft options, believe it or not.
Plant Perfect

While acknowledging that anyone trying to make a vegan mayonnaise has an uphill battle, the Plant Perfect Vegan Mayonnaise is not a healthy product. This mayo is made with ingredients like canola oil, modified corn starch, soy powder, and xanthan gum. A good reminder that vegan doesn’t always translate to healthy.
Kraft Reduced Fat Mayonnaise with Olive Oil

Kraft Reduced Fat Mayonnaise with Olive Oil is somehow packed with more additives than the regular Kraft mayo. Pros: Cage-free eggs and olive oil. Cons: There’s not just olive oil in this mayonnaise but also soybean oil and canola oil, plus modified food starch.
