Least Processed Salad Dressings
Each product is ranked by its own Processing Score, lowest 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
Is salad dressing ultra-processed?
Simple oil-and-vinegar dressings score low. Commercial creamy dressings with emulsifiers, preservatives, and artificial flavors score high. The gap is enormous within this category.
What is the healthiest salad dressing?
In our analysis, the least processed salad dressing options are simple vinaigrettes with olive oil, vinegar, and herbs, which score at the bottom of our scale. Among store-bought dressings, the ones ranked here achieve the lowest processing scores by keeping ingredient lists short and avoiding industrial emulsifiers.
Is ranch dressing ultra-processed?
Commercial ranch dressing typically scores high, with MSG, artificial flavors, modified food starch, preservatives, and multiple emulsifiers needed to keep the cream-based emulsion stable on shelves.
How do you make a simple salad dressing?
A basic vinaigrette takes 30 seconds: whisk 3 parts olive oil with 1 part vinegar (red wine, balsamic, or lemon juice), add a teaspoon of Dijon mustard, salt, and pepper. This scores far lower than most bottled equivalents. You can add fresh herbs, garlic, or honey for variety without increasing the processing level.
