Milk is a drink that many people love to drink. Children in the growth and development stage, as well as middle-aged and elderly people, need to supplement milk to absorb the calcium in it. Milk also has the effect of calming the mind and helping sleep.
However, "there are many people who are popular," and some people even say that the hormones in milk are very high, which will cause premature puberty to children, and even increase the risk of cancer due to excessive additives in it. Is this really the case?
Milk contains a lot of hormones, which can lead to precocious puberty and cancer. Is it trustworthy? The gastroenterologist tells you
Beijing Friendship Hospital Nutritionist Gu Zhongyi said: Everyone’s concerns are completely redundant, because taking hormones to produce milk is completely unnecessary. In this way, cattle, like other mammals, will produce milk after giving birth to calf.
Cows, like other mammals, secrete milk after giving birth to calf and do not need to be deliberately given hormones. If a cow wants to produce milk all the time during its lactation cycle, the cow that undergoes artificial insemination and fertilization during the lactation period will give birth to the calf again and continue to produce milk.
milk source is a problem that people are more worried about, because it may contain certain hormones. In foreign farms, dairy cows are usually given growth hormone . This hormone will increase the milk production of dairy cows by dozens of percent, but this hormone is strictly prohibited in China.
"Sex hormone" has no meaning for cows to produce milk. If farmers use it without authorization, it will be counterproductive. Milk is a drink we often drink in our lives, and feeding milk is not as complicated as we imagined.
In 2010, the former Ministry of Health gave a related answer on "Q&A Related Questions and Answers for Children's Premature Sexual Maturity and Milk Estrogen": The estrogen in milk is lower than breast milk, and it does not cause any serious harm to children. Everyone can treat it rationally.
Milk can lead to precocious puberty. So are children who drink breast milk more likely to have precocious puberty? In fact, this is completely overthinking. Milk is a very healthy drink, and everyone must treat it scientifically.
Some people also believe that the hormones in milk will be overflowing, so it will increase the risk of cancer. Mammals only produce milk during pregnancy and breastfeeding. Therefore, in order to increase the probability of milk production, it is necessary to ensure that there is enough progesterone and estrogen in the cow's body. The milk does contain extremely trace amounts of natural endogenous estrogen.
It is necessary to pay attention to the hormones that affect physical health are circulating hormones in the blood. Most of the hormones eaten will be catabolized by the liver after entering the digestive system. The amount of the blood that can be catabolized by the liver is almost negligible. The hormones in milk will not increase the risk of cancer. There is no need to worry too much about the impact of milk on health. In fact, milk is not as high as everyone imagines. Instead, it has extremely high nutritional value and can meet the needs of the body.
The final research results found that as long as you buy milk produced by a regular manufacturer and consume it reasonably, it will not affect your own health. Some people think that since milk is so healthy, is it better to drink more? In fact, excessive milk intake is also unfavorable.
What are the dangers of drinking too much milk?
Milk is a common drink in daily life. It is rich in calcium, phosphorus, protein and other substances, which can supplement trace elements and nutrients needed by the human body in daily life. However, drinking too much milk may cause discomfort, allergies, gastrointestinal discomfort, and may also increase the burden on the kidneys or cause obesity in the body.
. Allergic: If you are allergic to milk, you may experience allergic symptoms such as itching, rash, and difficulty breathing after drinking milk;
. Gastrointestinal discomfort: If the body is intolerant to lactose or drinks a lot of raw and cold milk, it may cause the gastrointestinal tract to catch cold. In addition, milk is a gas-producing food, which may cause gastrointestinal discomfort such as nausea, vomiting, abdominal distension, and abdominal pain in the body. ;
. Increase the burden on the kidney: The water and protein content in milk are large, mainly through the kidney metabolism. If you drink too much milk, it will increase the metabolic burden on the kidney;
. Cause obesity: Milk contains lipids and carbohydrate . If you drink a lot of milk, the body will consume a lot of calories but not enough calories. The excess calories will be stored in the body in the form of fat, which will cause obesity.
How to choose the right milk for you?
(1) Pure milk
Supermarket often sees pure milk divided into pasteurized milk or room temperature milk . Pasteurized milk sold in supermarkets with a short shelf life is pasteurized milk obtained by pasteurizing using raw milk as raw material. Pasteurized milk is the best preserved milk product with the best taste, but its shelf life is short and requires low temperature storage, and the price is relatively high.
room temperature milk is not as good as pasteurized milk, but its main nutrients such as protein and minerals are basically retained. In terms of nutritional value, it is basically the same as pasteurized milk. It does not require refrigeration when stored, and it only has a room temperature. It has a long shelf life, which is convenient for family purchase and storage, and the price is relatively cheap.
(2) Breakfast milk
Some merchants add cereals, cereals, etc. to the milk to make it look more nutritious and taste more acceptable. We can look at the nutritional ingredients of this dairy product, pure milk + water + sugar + wheat essence/walnut powder, etc. + some nutritional enhancers + edible essences. Although the taste is sweet and delicious, its nutritional value will be lower than that of pure milk.
(3) Skim milk
Skim milk while removing fat, it will also remove fat-soluble vitamin , such as vitamin A, vitamin D and vitamin E. The strong milk taste is mainly attributed to fat. Milk that has lost its fat will taste very light and lacks the milky aroma.
If you are healthy adults and teenagers, try to choose whole milk . For people with fat loss and weight loss and hypercholesterolemia, you can choose skim milk.
(4) Zero Lactose Milk
Lactose intolerance is due to the lack of lactase in the digestive tract or the activity is reduced. It cannot decompose lactose in milk or dairy products into glucose and galactose, causing symptoms such as abdominal distension, abdominal pain, diarrhea, and increased gas production.
Lactose milk is a product produced by hydrolyzing lactose from solid phase lactose enzyme. The protein of zero-lactose milk is not much different from that of milk. People with lactose intolerance can choose zero-lactose milk to avoid discomfort in drinking milk.
(5) high calcium milk
Milk itself is very rich in calcium, and the calcium content per 100ml of milk is about 90-120mg. The calcium content of high-calcium milk must reach 120mg/100ml to meet the national standards. The raw material of high-calcium milk is milk. During production, some calcium is artificially added, and most of the additional calcium is calcium carbonate or calcium lactate, and the absorption and utilization rate of the human body is not high.
Adults ensure 300g of milk or dairy products every day, plus green leafy vegetables and tofu, which can basically ensure daily calcium needs.
(6) Milk beverage
Milk beverage is not milk, but because of the packaging and name, it is often misunderstood as milk.my country's national standard (GB/T21732-2008 milk-containing beverages) stipulates that the protein content of prepared milk-containing beverages and fermented milk-containing beverages shall not be less than 1%, the protein content of lactic acid bacteria beverages must not be less than 0.7%, and the protein content of pasteurized milk and sterilized milk shall be above 2.9%. The protein content of milk drinks is far less than that of milk.
