Most Processed Plant-Based Milks
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.
Plant-Based Milk by the Numbers
We scored every plant-based milk product in our database: 1,404 items across 243 brands. In our analysis, about 56% land in the Highly or Ultra-Processed tiers.
What should you look for on the label?
- Simple plant milks list only the base ingredient, water, and salt
- Oils (sunflower, rapeseed) are added for mouthfeel, not necessity
- Gellan gum, locust bean gum, and carrageenan are common stabilizer additives
- "Barista" versions add extra oils and stabilizers for frothing capability
- Plant based oat milk brands vary widely in additive load; compare ingredient counts before choosing

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
What is the enzymatic process in oat milk?
Oat milk production uses industrial enzymes (amylase) to break down oat starches into simple sugars, creating the creamy texture. This is why oat milk tastes sweet without added sugar: the starch has been converted.
Why do plant milks need so many additives?
Plant-based ingredients do not naturally emulsify with water the way dairy fat does. Oils, gums, and emulsifiers are needed to prevent separation and create a milk-like consistency.
Are barista blends more processed?
Yes. Barista plant milks add extra oils (rapeseed, sunflower), dipotassium phosphate, and additional stabilizers to achieve the frothing and steaming properties that baristas need.
