However, there is a saying about the circulation of milk in real life: "Milk is full of preservatives, drinking milk is toxic and carcinogenic!"
In fact, there are many rumors about milk over the years, there are real and fake, so many friends cannot distinguish between real and fake. In order to give everyone more understanding and understanding of milk, I will have a good chat with you today about the relevant knowledge.
About milk
[Nutritional ingredients of milk]
Milk is rich in minerals, calcium, phosphorus, iron, zinc, copper, manganese, and molybdenum. The most rare thing is that milk is the best source of calcium in the human body, and the calcium-phosphorus ratio is very appropriate, which is conducive to the absorption of calcium.

[The benefits of drinking milk]

, protect cardiovascular
choline contained in milk can regulate the concentration of cholesterol in the blood. The orosic acid contained in it can help the human body inhibit the production of low-density cholesterol in the liver, and together with choline, reduce the lipid content of , which can soften blood vessels and prevent blood clots.
[These 4 types of people may not be suitable for drinking milk]
. People with iron deficiency anemia
If they want to be absorbed and utilized, the iron in the food must be converted into ferrous. However, the calcium and phosphorus salts in milk will react with ferrous to form insoluble compounds, which are not conducive to iron absorption.
. Lactose intolerance
milk has a high content of lactose. Lactose must be in the digestive tract and can only be decomposed and absorbed through the action of lactonic acid . If lactonic acid is lacking, drinking milk will cause symptoms such as abdominal pain and diarrhea.
. People with milk allergies
Some people are allergic to milk. After drinking milk, they will experience symptoms such as abdominal pain and diarrhea. Some people with severe allergies may even experience symptoms such as asthma or urticaria, which threatens life safety, so people with milk allergies must not touch dairy products.
, peptic ulcer
peptic ulcer diseases including gastric ulcer , duodenal ulcer and other diseases. The gastrointestinal mucosa of this type of patients often suffer from damage, and drinking milk will stimulate gastric acid secretion, causing gastric acid to stimulate the ulcer area to worsen, which may lead to worsening pain symptoms.
Milk is full of preservatives, which are not only toxic but also carcinogenic?
Why does it talk about preservatives? The reason is that some people find that the shelf life of milk varies greatly. Some milk can only be stored for a few days, some can be stored for one month, and some can be stored for several months or even a year and will not deteriorate!
Therefore, some people think this is the effect of preservatives, but the truth is not the case.
Experts have long pointed out that pure milk does not contain preservatives. Because after the production process of pure milk undergoes disinfection and sterilization, the quality of the milk can reach the shelf life requirements.
Different varieties of milk have different shelf life determined by the production and packaging methods, and it is not the addition of preservatives to make the shelf life longer. Each batch of milk will have more or less some harmless bacteria left, so the best date to consume is actually an estimate of when the milk with the most bacteria will go bad.
At this time, some people will say again that although milk does not contain preservatives, it does contain insulin growth factor (IGF-1) and tyrosine . These two substances are definitely harmful to health! There is no scientific basis for the statement
. The Chinese Dietary Guidelines recommend that you consume 300g of milk every day. Milk can help the human body replenish nutrition and eat a healthy diet, and will not lead to an increase in cancer risk.
Doctor reminds: Only these three types of "milk" really need to drink less
, probiotic dairy products
probiotic dairy products are also very popular now. To put it bluntly, it is a variety of yogurt products with a sour and sweet taste, and children love it.
And this type of dairy products are also sold under advertisements to aid digestion and nourish nutrition, which is extremely popular, but doctors do not recommend giving children too much of this dairy products.
The probiotic dairy products on the market now contain a lot of additives and sugars, because the real fermented milk tastes sour and has a bad taste. Most of these additive ingredients are to neutralize the taste, but they are not friendly to the stomach and intestines of children. Eating too much will lead to indigestion and frequent illness.
, high calcium milk
Milk itself is a high calcium food, and it is not necessary to add additional calcium, but under the banner of high calcium, it can make people who don’t know the truth willing to pay for it, which is a successful marketing method. The calcium in a box of high-calcium milk (250ml) is about 60mg higher than pure milk. Drink two sips of pure milk and eat a small piece of dried tofu and make up for it.
However, high-calcium milk is not much more expensive than pure milk. If you don’t drink much milk and cannot guarantee that you can eat soy products and vegetables every day, then drinking is not wrong. To make up for it more is a little more.
However, additional calcium will precipitate the protein in the milk. Thickening agent must be added to stabilize it. The taste of this milk will be worse when it drinks high-calcium milk. Instead of drinking high-calcium milk, it is better to eat more stewed tofu and stir-fried dried tofu and drink two more sips of pure milk.
, breakfast milk
Add a large amount of cereals and cheese and other ingredients to breakfast milk, which greatly meets the children's breakfast content needs. Morning time is relatively tight, and many people will have the habit of staying in bed, so parents don’t have much time to prepare nutritious breakfasts for their children, and they will use breakfast milk instead.
But breakfast milk is breakfast milk after all, and you cannot drink too much. You can tell from your taste that many ingredients such as flavors, preservatives are added to breakfast milk.
preservatives contain chemical element . If you drink too much, it will have adverse effects on the health of your child. Parents should reduce the number of purchases for their children and control the amount of intake of their children.
There is also a "golden period" for drinking milk. These 3 time periods are best
. Half an hour after breakfast
Many people will match milk when eating breakfast, and many people treat milk alone as breakfast. In fact, from a nutritional point of view, drinking milk is healthier after half an hour after breakfast.
If you drink milk without eating in the morning, it will cause harm to the stomach and intestines, and the body cannot fully absorb the nutrients in the milk. Drinking milk after eating breakfast for half an hour can help the human body replenish nutrition and strengthen physical fitness.
. After 3 pm
This time period, the human body is very tired and needs to replenish energy in time. Drinking milk during this period can relieve the body's fatigue and fatigue that occurs in the day, and can also effectively nourish your intestines, so that the intestines can better metabolize feces, and effectively promote intestinal peristalsis.
Not only that, this period is a very sleepy time, and drinking a glass of milk can relieve it. This situation not only replenishes sufficient nutrition but also replenishes the lack of spiritual vitality.
, Half an hour before going to bed
The nutrients contained in milk can synthesize tryptophan with serotonin. This substance can relax the brain and improve sleep quality. In addition, milk also has a certain hypnotic effect. Drinking milk half an hour before bed can help us fall asleep effectively. After we absorb the calcium element in milk, it can effectively relieve anxiety, let us fall asleep faster, and at the same time better supplement calcium element to avoid osteoporosis.
