"Kidneys" have long been a prized aphrodisiac for men, especially when grilled and eaten as skewers. Driven by the belief that eating a certain part of an animal strengthens the corresponding part of the human body, this food takes on a suggestive connotation. However, experts are warning men seeking to invigorate their kidneys that consuming too many "kidneys" could lead to infertility.
Recent research has found that the livers and kidneys of pigs, cattle, and sheep contain varying amounts of the heavy metal cadmium. While people consume these organs for their supposed health benefits, they are also ingesting cadmium, which can potentially cause infertility. For smokers, this risk increases dramatically, with the likelihood of infertility reaching up to 60%.
Cadmium can induce degenerative changes in the structure and function of male reproductive tissues such as the testes and epididymis, ultimately leading to a decline in fertility.
The World Health Organization (WHO) recommends that a person's weekly exposure to cadmium should not exceed 7 micrograms per kilogram of body weight. "Kidneys," considered a food that "boosts sperm," contain high levels of cadmium. The harm caused by cadmium to the body's tissues and organs is multifaceted, primarily affecting the kidneys, liver, and reproductive function. It not only reduces sperm count but can also impact the implantation of a fertilized egg. Cadmium can damage chromosomes, making it difficult for the fertilized egg to implant and thus affecting conception.
For smokers, the risk of infertility is as high as 60%, as a single pack of cigarettes can increase the body's cadmium content by 2 to 4 micrograms. Furthermore, chronic cadmium poisoning can cause kidney damage or lead to bone diseases.
Finally, it is advisable to remember that foods high in zinc can help the body expel cadmium. Therefore, to prevent excessive cadmium intake, one can choose foods rich in zinc. It is recommended to eat more vegetables and fruits. High-zinc foods are primarily shellfish, with oysters containing the most zinc. Alginic acid in seaweed can also help excrete cadmium from the body. Apples contain galacturonic acid, which is quite helpful for detoxification. Consuming more milk and soy products is also beneficial, as their rich calcium content acts as a useful "toxin remover." Additionally, it is important to quit smoking and minimize contact with cadmium-containing items such as batteries.
