Some experts have mentioned that milk from cows treated with growth hormones contains a factor, IGF1, that promotes the occurrence of breast cancer, and thus claim that milk causes breast cancer.
In fact, the development of breast cancer is influenced by many factors, including genetic factors, obesity, high estrogen levels, excessive dietary fat, lack of exercise, and more. Milk consumption is not a significant risk factor.
The expert themselves also admit that ordinary milk does not contain high levels of IGF1; only milk from cows treated with growth hormones may contain high levels of IGF1, which could potentially promote the development of breast cancer. So, why should all milk be condemned?
In fact, milk contains anti-cancer substances like conjugated linoleic acid (CLA), which can prevent the occurrence of various cancers. Furthermore, components such as butyric acid and ether lipids in milk are also beneficial for cancer prevention. On this point, however, Dr. Lin seems to have intentionally or unintentionally overlooked it. Many studies also show that the more milk and dairy products are consumed, the lower the incidence of colorectal cancer, and the incidence of breast cancer is also slightly reduced. It is clear, then, to link milk with cancer is simply unfair.
If you drink more yogurt, it can also have a certain preventive effect against cancer. Animal studies have confirmed that yogurt can enhance the body's immune function, increase the activity of macrophages, promote the release of tumor necrosis factor, and reduce the effects of carcinogens on the body.
Therefore, if you are not comfortable with milk, you might as well drink yogurt daily as a substitute, which can provide various health benefits.
