Least Processed Plant-Based Milks
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.
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. For a deeper look, see our Processing Score guide and Two-Score System explanation.
Frequently Asked Questions
Is oat milk ultra-processed?
Most commercial plant based oat milk scores fairly high because of enzymatic treatment, added oils, stabilizers, and fortification. Simpler versions with just oats, water, and salt score lower.
Which plant milk is least processed?
Homemade nut milks (blend + strain) score at the bottom of our scale. Among commercial options, simple almond or coconut milks with 3-5 ingredients score lowest. For vegan milk shoppers, unsweetened coconut milk is often the simplest formulation.
Is regular dairy milk less processed?
Plain pasteurized milk scores well below most commercial plant milks. Pasteurization is a simple heat treatment, not chemical processing.
Is organic milk less processed than conventional?
From a processing standpoint, organic milk and conventional milk score the same, since both undergo the same pasteurization. The difference is in farming practices: organic milk comes from cows raised without synthetic hormones or antibiotics. Grass fed milk follows a similar pattern, with the benefit being feed quality rather than processing level.
