A Plant Milk That Matches Cow's Milk Protein
Soy milk is one of the few plant milks that naturally approaches the protein concentration (~3.3g/100ml) and amino acid profile of whole dairy milk -- most other plant milks (almond, oat, rice) fall well short unless separately protein-fortified; pea-protein-based milks are a newer, less common exception that can also reach comparable levels.
