Although pea protein powder and soybean protein powder are both popular nutritional and health products, they are also different. Pea protein powder has a high content of protein, which is very suitable for postpartum mothers to drink, because it is a product with 0 plus 0 fat and 0 cholesterol, which can increase the satiety of postpartum mothers after drinking and has a good effect on restoring their health. Soybean protein powder belongs to plant protein, which is less than pea protein powder, but it is also helpful to improve the body's disease resistance and the postoperative recovery of patients.
