Many men love eating animal offal, but they should pay attention to the amount consumed. It is best to eat it no more than once or twice a week, and each serving should not exceed 50 grams. Pig kidneys, in particular, are a favorite for many men. However, experts have recently warned that eating offal for health benefits could lead to infertility due to the heavy metal "cadmium".
For those who believe in "like cures like," be careful. Eating too much not only fails to nourish the body but may also cause infertility. According to the latest research, the livers and kidneys of pigs, cattle, and sheep all contain varying amounts of the heavy metal cadmium. While people eat these for their supposed health benefits, they are also ingesting cadmium, which can lead to infertility. For smokers, the risk of infertility is as high as 60%.
Experts explain that some people eat animal offal with the mindset of "like cures like," but patients with kidney disease should not eat animal kidneys excessively. Patients with impaired kidney function need to limit their nutrient intake. Moreover, animal kidneys are high in cholesterol, and excessive consumption could加重 the burden on the kidneys, leading to further deterioration of kidney function.
In addition, these foods considered to be "sperm-boosting" contain high levels of cadmium, which not only reduces sperm count but also affects the implantation of fertilized eggs. Cadmium can damage chromosomes, making it difficult for fertilized eggs to implant and thus affecting pregnancy.
Rational consumption of animal offal:
Animal offal is not useless "waste"; it has nutritional value, being rich in trace elements like iron and zinc, as well as various vitamins. Consuming these animal offal in a reasonable manner can effectively meet the body's demand for these trace elements and nutrients.
