Most Processed Salad Dressings
Each product is ranked by its own Processing Score, highest first. To keep the list from being one company's catalog, it shows at most two products from any one brand.
Salad Dressing by the Numbers
We scored every salad dressing product in our database: 4,563 items across 477 brands. In our analysis, about 85% land in the Highly or Ultra-Processed tiers.
What should you look for on the label?
- Oil and vinegar should be the first ingredients in vinaigrettes
- Avoid EDTA (calcium disodium EDTA), a chelating agent used as a preservative
- "Light" dressings replace oil with water and add more thickeners and sweeteners
- Xanthan gum and modified food starch are emulsifier red flags

How are products scored?
Every product is evaluated using two independent scores. The Processing Score (lower is better) measures the degree of industrial processing based on ingredient analysis, including the presence of artificial additives, preservatives, and highly modified ingredients. The Nutrition Score (higher is better) rates overall nutritional quality, rewarding protein and fiber while penalizing excess sodium, added sugars, and saturated fat.
Products are assigned to one of four processing levels: Minimal (score ≤ 2.5), Processed (2.6 to 5.0), Highly Processed (5.1 to 8.0), and Ultra-Processed (above 8.0). Each product in the ranking is placed by its own Processing Score, not by its brand. Based on our analysis of 445K+ curated products from the USDA FoodData Central database.

Frequently Asked Questions
Why are creamy dressings so processed?
Oil-in-water emulsions (like ranch and Caesar) require industrial emulsifiers, stabilizers, and preservatives to remain stable for months on store shelves. Homemade versions separate within days.
Are "light" dressings less processed?
No, usually more processed. Removing oil requires adding modified food starch, corn syrup, and additional thickeners to maintain texture, often increasing the ingredient count.
What preservatives are common in dressings?
Potassium sorbate, sodium benzoate, calcium disodium EDTA, and TBHQ are the most common dressing preservatives. Natural preservatives like citric acid are less concerning.
