“Milk is full of preservatives, poisonous and carcinogenic. Don’t eat it!”

Yesterday Mr. Zhang bought a box of children’s milk from the supermarket and wanted to give it to The son was supplementing nutrition, and as soon as he brought it home, he was seen by the neighbor Aunt Liu. Aunt Liu said that the current milk can be stored for a long time, because a lot of preservatives are added, and drinking it for a long time will cause poisoning and cancer.

Isn’t it good to drink milk? Mr. Zhang was puzzled, but looking at Aunt Liu’s serious face, he decided to go home to check first. Unexpectedly, there are still a lot of articles on the Internet saying that milk causes cancer.

In the eyes of medical nutritionists, milk is rich in nutrients and is also known as “white soft gold”, but it is often said that milk causes cancer. Good product, or white poison?

First, milk contains a lot of preservatives, which is toxic and carcinogenic?

What exactly are preservatives? Why do so many people talk about discoloration about it?

A preservative added to food is a substance that prevents the reproduction of microorganisms in food and prolongs the shelf life of food. Common preservatives include benzoic acid, sorbic acid,sulfites and nitrites, and some raw milk may use hydrogen peroxide to keep it fresh (state regulations only allow it to be used in Inner Mongolia and Heilongjiang).

So, is the shelf life of milk in supermarkets so long now because of the addition of a lot of preservatives?

Of course not! Hu Changli, Ph.D., Key Laboratory of Functional Dairy, China Agricultural University said, national standards stipulate that pure milk is prohibited in Add preservatives. The long shelf life of milk is mainly due to the sterilization storage method, and these two sterilization methods are the most commonly used.

1. Ultra-high temperature sterilization technology

Using ultra-high temperature technology to instantly heat milk to 135~150°C for 2~6 seconds. In this process, almost all bacteria can be killed, which can extend the shelf life of milk to more than 6 months. Milk sterilized by ultra-high temperature technology can also be stored at room temperature. Depending on the quality of milk, processing methods and packaging forms, the shelf life of milk will vary from 6 to 12 months.

2. Pasteurization

Pasteurization is the use of 60~85 °C to kill pathogenic bacteria while preserving the flavour of the milk. Pasteurized milk generally has a shelf life of only a few days and requires full cold chain transportation.

Some companies will increase the temperature when using pasteurization, and the packaging will also use composite packaging with better sealing. Milk in this case can be stored at room temperature, andshelf life can be extended to around 30 days.

That is to say, regular pure milk does not contain preservatives at all, saying The claim that drinking milk is poisonous and carcinogenic is naturally broken.

Second, is it good or bad to drink milk for a long time?

Of course there are more benefits, “Dietary Guidelines for Chinese Residents” 2016 recommends that Chinese people drink about 300g of milk every day, These three health benefits of drinking milk that everyone needs to know about.

1. Calcium supplement

Milk is very rich in calcium, 300ml milk The calcium content in it is close to 300mg, which is close to 40% of the recommended daily calcium intake.

In addition to being rich in calcium, milk also contains factors such as vitamin D, lactose and amino acids that can promote calcium absorption, so the human body can absorb and utilize calcium in milk. very high.

2. Supplement high-quality protein

300ml of milk contains about 9g of protein, It is 16.4% of the recommended daily intake for adult women. And the protein in milk can reach more than 90% digestibility after entering the body, and the essential amino acids contained in it also meet the needs of the human body. Drinking milk can make the body supplement a large amount of high-quality protein.

3. Digestion

The lactose contained in milk can regulate the secretion of gastric acid after entering the body, which can promote the secretion of digestive juice and help the peristalsis of the gastrointestinal tract. and other minerals absorption.

For most people, drinking milk in life can bring great health benefits, and there is no need to worry about milk containing preservatives. When we buy milk, we should pay more attention not to buy these two kinds of “fake milk”.

Third, compared with preservatives, it is actually more to beware of “fake milk”

Pure milk refers to drinks with only raw milk in the ingredients, and < /span>The main ingredients of dairy-containing beverages are often water, white sugar, fruit flavors, etc., and only contain a very small amount of protein and minerals.

These two kinds of milk commonly used in life are not real pure milk, and their nutritional value is not comparable to pure milk. They can only be regarded as milk-containing beverages, but many people still think that they are milk, with High nutritional value, this is a misunderstanding.

1. Breakfast milk

Breakfast milk Generally, there are many flavors, including walnuts, red dates, oats, etc. Compared with ordinary pure milk, breakfast milk with these substances added will look healthier and nutritious, and taste better.< /p>

In fact, breakfast milk is not pure milk. It is made by diluting pure milk and adding sugar, nuts, grains, and even flavors. Its nutritional value does not It is higher than milk, but the taste will be richer.

2. Children’s milk

The average price of children’s milk is much higher than that of pure milk. In fact, it is not higher than ordinary pure milk. Children’s milk is only made of pure milk with added sugar and other ingredients. Most children’s milk contains at least 5 additives.

Long-term consumption of milk-containing beverages will bring many health risks to the body, includingObesity, fatty liver, diabetes, partial eclipse, picky eater and a series of hazards.

In life, drink Milk must be drunk selectively to avoid buying “fake milk”. In addition to paying attention when choosing milk, there are also some things to pay attention to when drinking milk.

Fourth, drink milk, give you three suggestions

1. As soon as possible after opening After drinking

Milk will lose a lot of nutrients if it is not consumed in time after opening, and it is prone to bacterial infection, which will bring some unnecessary risks to health .

2. Warm milk is best

It is recommended to drink milk every day to warm it However, both iced milk and hot milk are not suitable. Ice milk will irritate the stomach, and boiling milk will destroy the nutrients.

3. Swallow slowly

It is best to swallow slowly when drinking milk. Maximize the absorption rate of milk. Drinking milk in a big mouth or drinking it at one time will increase the osmotic pressure in the intestinal tract at one time, and the peristalsis of the gastrointestinal tract will be accelerated, the speed of milk excretion will also be accelerated, and the absorption rate will be greatly reduced.

Milk is a highly nutritious food that is very common in life, and it is suitable for most people. In life, we must learn to identify rumors and avoid letting ourselves step into misunderstandings. At the same time, we must pay attention to the precautions for drinking milk, so as to maximize the absorption rate of nutrients in milk by the body as much as possible. #HealthStarProject# #Health2022#
