Is drinking milk harmful?

Milk is rich in nutrition, and more and more people drink milk every day. However, many studies have found that men who drink milk regularly are prone to prostate cancer. Prostate cancer is a common malignant tumor in male reproductive system. A research team in Boston, USA, conducted a 1 1 year follow-up survey on 20,885 American male doctors. Dairy products mainly include skim milk, whole milk and cheese, among which 10 12 men suffer from prostate cancer. After statistical analysis, it was found that the plasma concentration of 1, 25- dihydroxyvitamin D3 (with anti-prostate cancer effect) in men who consumed 600 mg of calcium every day was significantly lower than that in men who consumed 150 mg of calcium from dairy products every day, and the risk of prostate cancer increased by 32%. After excluding age, weight, smoking, physical exercise and other influencing factors, it is found that men who eat more than 2.5 servings of dairy products every day (each serving is equivalent to 240ml of milk) have a higher risk of prostate cancer than men who eat less than 0.5 servings of dairy products. Researchers in Philadelphia, USA, also confirmed through the epidemiological survey in recent years 10 that eating more dairy products will increase the risk of prostate cancer in men. Domestic studies have also found that milk intake is significantly related to the incidence of prostate cancer, which may be due to the high estrogen content in some brands of milk. Fortunately, some plant compounds in fruits and vegetables have certain anticancer effects. Lycopene is an important carotenoid, which widely exists in fruits and vegetables. Tomatoes, apricots, guava, watermelon, papaya and red grapes all contain more lycopene, especially in tomatoes. American researchers conducted a six-year follow-up survey of 46,000 men and found 773 cases of prostate cancer. The study found that compared with people who don't eat raw tomatoes, people who eat raw tomatoes 2-4 times a week have a 26% lower risk of prostate cancer, and tomato pizza and ketchup also have this effect; Eating lycopene directly can also reduce the risk of prostate cancer. The antioxidant activity of lycopene is the strongest among natural carotenoids. It can protect the genetic material DNA (deoxyribonucleic acid), inhibit the proliferation of cancer cells and regulate the hormone state. Its anti-prostate cancer effect has been confirmed by a lot of studies. Therefore, in order to care for the prostate, men should drink milk slowly and don't treat it as a drink. In addition, they should pay special attention to balanced nutrition and eat more tomatoes every day.
