Miao Jiwen, vice president of the National Council of Famous Doctors, pointed out that animal kidneys contain androgens and adrenocortical hormones, which people think can tonify the kidney, but the actual effect has not been verified by rigorous scientific research. In addition, food pollutants have been reported in many areas, and the contents of heavy metals such as cadmium and lead in animal kidneys exceed the relevant limits. If you eat roasted kidney and other foods frequently, the excessive heavy metals can not be discharged in time, but will reduce the reproductive capacity and endanger the kidneys and reproductive system.

Therefore, people with kidney diseases or renal insufficiency should not eat animal kidneys regularly, because these people can't metabolize heavy metals in food well, and the high cholesterol content in animal kidneys will increase the burden on the kidneys, so that the renal function will not be strengthened, but will be damaged. Bian Xiao: The theory of traditional Chinese medicine says that shape complements shape, and dirty supplements dirty. It can be considered that animal organs that constitute the same organs of human body may also contain the same and similar components. If you eat it directly, it should be said that this view is scientific. However, in today's reality of serious environmental pollution, the relevant internal organs should be eaten in moderation, and it is not appropriate to eat them in large quantities for the purpose of treatment.
