Can drinking milk cause cancer? Is it true that drinking milk causes cancer

Everything is somewhat harmful, so you can drink it if you want.

You would have gotten cancer in the first place. Why blame the milk?

Which calf have you ever seen that had to be drunk to death?

There is a rumor circulating in <> circle of friends: milk contains hormones IGF-1 and casein, and these two substances are very powerful cancer promoters, and long-term consumption can cause breast cancer, ovarian cancer, prostate cancer, colorectal cancer and other series of cancers.

Truth: This rumor comes from the book "China Investigation Report" by Professor Campbell of Cornell University in the United States, in fact, the human body itself also contains IGF-1 hormone, a 220 ml bag of milk contains only about 539 nanograms of IGF-1, and an adult produces about 10 million nanograms of IGF-1 every day, which is about twice the content of a bag of milk.

Moreover, there is currently no scientific evidence that IGF-1 causes cancer.

In the "rat experiment" on casein, the casein used in the experiment was the only protein in the rats**, which is completely different from the dietary structure of people, and Campbell's research subjects were rats that had induced cancerous cells through high doses of aflatoxin (a strong carcinogen), and the cause of carcinogenicity in rats was that aflatoxin was not casein, and the results of the experiment were not applicable to humans.

Therefore, there is no scientific basis for the claim that drinking too much milk causes cancer.

Fake. It is mainly a British female professor who proposed that IGF-1 contained in milk is carcinogenic, and the specific explanation can be found in the explanation of Professor Chen Yourong, a professor of nutrition and fermentation at Shanghai Fisheries University in China, as follows.

Milk is recognized as a nutritious food all over the world, and it has not changed so far. It is rich in nutrients: carbohydrates, minerals, vitamins, proteins, fats.

If this female scientist really has this thing, a person cannot represent this statement, and must do a large number of rigorous controlled experiments to prove it, including clinical and animal ones.

IGF-1 is a growth factor, both humans and animals themselves, it has a growth-promoting effect, and in many countries it is a drug used to promote the physical growth and development of children. This further confirms that it is not included in the list of carcinogenic agents. Would like to add a question:

Why would anyone pay so much attention to the relationship between milk and cancer? This is closely related to one thing. In 1994, the FDA (Food and Drug Administration) approved the use of RBGH (recombinant bovine growth hormone), which can be used to promote milk production in dairy cows, which can increase production by up to 15%-20%.

However, when milk production is increased, the level of IGF-1 in this milk also increases (it may not be a year-on-year increase, but it does increase). When drinking such milk, people have a higher intake of IFG-1 than the milk produced by ordinary cows that have not used this hormone, which is several times higher. Further follow-up studies of women who drank this type of milk found that they did have a higher chance of developing breast cancer.

This result led to the belief that IGF-1 is a carcinogenic agent and that milk is related to breast cancer. But there is no conclusive evidence of a causal relationship between the two. Whether Chinese dairy farms use this hormone is not certain.

Recently, I have been paying attention to this issue so I also want to find a post to say two words of my opinion, in fact, "drinking milk will cause cancer" is difficult to say, the official uses scientific analysis to draw conclusions to refute rumors, but science is not omnipotent, there are many events that cannot be explained from a scientific point of view, such as the meridians of traditional Chinese medicine, from a scientific point of view, no matter with any instrument can not detect the meridians, but traditional Chinese medicine uses meridians and acupuncture points to treat diseases is also well known, so whether the meridians exist or do not exist? Returning to the sentence "drinking milk can cause cancer" has been refuted from various scientific angles, but there is an indisputable fact that among all mammals, only humans have been drinking milk since childhood, while other mammals will only drink milk when they are just born, and human cancer incidence is the highest. What does this mean?

There is a saying that "there is a saying that there is no wind and no waves", and whether drinking milk will cause cancer can only be regarded as an unknown.
