Most conventional soy milks contain between 7-12g of protein per cup. Generally, we need about 0.8g protein per kg of bodyweight (or calculate 0.36 x lbs. of body weight). This means, for many people just one serving of soy milk could make up almost a fourth of their RDA.
In case you’re wondering if the protein in soy milk is a ‘complete’ protein, you should know that almost all plant and animal-derived foods (except gelatin) contain all of the essential amino acids in varying amounts. This means if you consume a wide range of plant foods (including legumes, grains, nuts, and seeds) and eat enough calories per day, you are sure to get all of the essential amino acids.
