First of all, it is harmful to the baby's health.
The latest parenting collection in the United States points out that the reason why cows produce milk is to feed calves, not human babies. The famous American pediatrician, the author of Parenting Collection, pointed out that the content of saturated fat in milk is too high, which is not easy to be absorbed by the human body, and it is easy to cause arterial blockage and thrombosis. For young children, the most direct symptoms are hearing and respiratory system damage, and it will make the baby suffer from frequent urination and diabetes. Dr. Spock believes that babies should eat breast milk, soy milk, rice flour paste and other nutrients.
Second, childhood obesity.
Although dairy companies spend tens of millions of dollars bragging about the benefits of milk for weight loss and spare no effort to introduce various low-fat milk, the Archives of American Pediatrics and Adolescents Medicine published in June pointed out that children who quote milk more than three times a day are more likely to be obese, even if they eat low-fat milk. A study on 12,000 children aged 9- 12 confirmed this point. Therefore, children should drink more water instead of using milk as a drink, as some parents think.
Third, excessive lactose leads to diarrhea.
Milk is rich in lactose, and the normal standard of lactose content in pure fresh milk is 4.2%-5%, but these lactose can not be completely absorbed by human body. According to the data of Harvard University Public Health Research Center, Asians are the biggest victims of lactose overdose. 90% yellow people can't fully digest and absorb lactose in milk, and 70% black people and 15% hundreds of people also have this problem. Excessive lactose can cause problems such as abdominal distension and diarrhea. If you often drink milk and feel upset, then obviously you should consider eating less dairy products.
Fourth, fractures can supplement calcium for milk.
Some studies also question the idea that milk can supplement calcium to prevent and treat fractures and osteoporosis. A study on nurses' health in Harvard University involved 78,000 women, which lasted 12 years. The study showed that women who drank a lot of milk were twice as likely to have fractures as women who drank little or no milk. The main reason is that several kinds of protein in milk cause calcium loss. One third of calcium absorbed from milk will be excreted from urine, while two thirds of calcium absorbed from cheese will be lost. This is undoubtedly a blow to the merchants who sing "milk supplements calcium".
Verb (abbreviation of verb) induces ovarian cancer and prostate cancer.
A study completed by Karolinska Medical College in Sweden shows that drinking a lot of milk will increase the incidence of ovarian cancer in women. This is the conclusion reached by scientists after investigating more than 60,000 women who drink more than 2 cups of milk every day. Long-term follow-up studies show that women who drink dairy products more than four times a day have twice the incidence of ovarian cancer as women who drink two glasses of milk a day. In addition, through 196 1 to 199 1 100 professional reports, the researchers found that prostate cancer is related to eating dairy products-most men with prostate cancer consume more dairy products than healthy men.
Sixth, the harm of excessive hormones.
Experts also pointed out that when people drink milk, they may not think of all the pains that cows suffer in order to produce milk. Artificial insemination, abortion and prolactin injection every year are "cruel and inhuman" to animals. In addition, some dairy farms in California also inject so-called "empty pregnancy-promoting milk" into cows, so that cows can produce a lot of milk without pregnancy, and their output can reach 10 times of natural milk production.
Even without considering the feelings of cows, human beings should pay attention to the harm caused by a large amount of estrogen in milk. Specifically, excessive hormones can lead to precocious puberty, male dysfunction and female infertility.
Seven, air pollution
California, the state with the largest milk production in the United States, is also the most polluted place where cows fart in the United States. On August 1 this year, officials of the San Joaquin Valley city government in California announced that in order to reduce pollution, the government would make laws and regulations requiring all cows to "burp and fart hygienically". This is nothing new. It won't be surprising if you know that there are already six children who need to go to school with ventilators. Each cow emits 9 kilograms of exhaust gas every year, while there are 2.5 million cows in the San Joaquin Valley, and the total amount of exhaust gas emitted each year has far exceeded the air pollution caused by cars, trucks or pesticides.
Eight, drinking milk often can easily lead to prostate cancer.
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 is found that eating more dairy products will increase the risk of prostate cancer in men compared with men who consume 150 mg of calcium from dairy products every day. 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.
