In our daily life, we can apply the theory of "Red beans tonify the heart, soybeans tonify the spleen, mung beans tonify the liver, white beans tonify the lung, black beans tonify the kidney and five beans tonify the five internal organs". Soak red beans, soybeans, mung beans, white beans and black beans for three days, and then eat red, green, yellow, white and black bean sprouts every day, which is not only beneficial to your heart, liver, spleen, lungs and kidneys, but also promotes the absorption and utilization of iron and zinc. It is a good way to supplement calcium, zinc, iron and brain.
