For example, if there is a problem with the kidney meridian, you can eat some black miscellaneous grains for health, such as black fungus and black wolfberry, because black food enters the kidney meridian and can tonify the kidney.
For another example, pregnant women and lactating women can eat some foods such as walnuts, which can help the fetus or baby improve their intellectual development.
Of course, there are many prescriptions for symptomatic health care. Before keeping in good health with whole grains, you should first know what your constitution is like, and you should not keep in good health blindly, otherwise it will not achieve the effect and even have side effects.
