The nutrition of milk and soybean milk will not be lost because of superposition, but will be enhanced because of complementarity, so they can be drunk together. Walnuts can nourish the brain, but black beans are not easy to wear out. It usually takes a while to soak first. I usually soak at night and drink soybean milk the next morning, which is fresh and nutritious. Oats are relatively green and are called Bromus and Wild Wheat in Compendium of Materia Medica. Oat is not easy to peel, so it is also called skin oat, which is a food with low sugar, high nutrition and high energy. It is very nutritious to milk together, and I hope to adopt it.
