Soy milk is the only plant milk with a protein content comparable to cow's milk (8 g/glass). Soy protein is complete — it contains all 9 essential amino acids.
Soy or pea milk — they have the most protein (8 g/glass). Oat milk is also good because it provides a pleasant thick texture. Avoid rice milk — too little protein.
