Milk is full of hormones and preservatives. It is poisonous and carcinogenic? There are 3 kinds of 'fake milk' to recognize

Grandma Wang received a call from her daughter and wanted to take her grandson to visit her old man. So, Grandma Wang specially bought milk and a lot of food to prepare.

Unexpectedly, after my daughter got home, she said that Grandma Wang's milk was bought by mistake, and it was bought as a drink, which could not be given to her grandson. She also said that the milk contains a lot of preservatives, so the shelf life is long, and I heard that it is poisonous and carcinogenic. The son's milk powder to drink.

Grandma Wang was puzzled. The milk was recommended by the salesman. It clearly said that it was suitable for everyone to drink. She also said that milk was especially good for people. What exactly happened?

1. There are hormones and preservatives in milk, which are toxic and carcinogenic?

There are rumors that growth hormones and sex hormones are added to milk, but the truth is that foreign milk may indeed contain growth hormones. Adding a prescribed dose of growth hormone is to increase milk production and is a legal addition.

In our domestic milk, the addition of growth hormone is prohibited . As for sex hormones, it has no practical significance for cow milk production. For example, adding estrogen will inhibit cow milk production, so it will not be added, so you don’t have to worry about hormones in milk. .

For milk with a long shelf life, many people also worry about whether it has added preservatives. In fact, the shelf life of milk is not directly related to preservatives . It is mainly related to the sterilization method when processing milk. The manufacturer only needs to heat the milk to 135 in an instant. ℃ to 150 ℃ and continue for a period of time, it will obtain a high sterilization effect, and the finished milk can be stored for more than 6 months at room temperature.

There are also rumors that the tyrosine in milk and the insulin growth factor IGF-1 have carcinogenic effects. This is pure rumor!

Regarding the carcinogenicity of tyrosine, it is actually a misunderstanding of a certain experiment in the United States by the public, and it does not prove that bovine tyrosine can cause cancer.

In addition, the content of IGF-1 in milk is very small, and its activity will also be reduced in the process of heat sterilization, and the possibility of cancer is not high. There is currently no evidence that milk causes cancer.

Second, milk is a big family, which is healthier?

Many people plan to buy milk to supplement nutrition, but there are so many types of milk on the market that they don’t know how to choose. Which milk is healthier and nutritious?

Milk on the market is divided according to the fat content per 100ml, mainly including four kinds: 3.25% fat whole milk, 2% fat partial skim milk, 1% fat low-fat milk and 0% fat skim milk .

When choosing milk, the key is to see which milk is suitable for your body.

Diabetes, high blood fat and obese people: It is recommended to choose low-fat or skim milk, so that you can supplement nutrition without worrying about fat.

·Children and pregnant women: Whole milk retains most of the nutrients, and it is recommended that such people drink whole milk.

Lactose intolerant people: These people are prone to diarrhea when they drink lactose-rich milk, and it is recommended to drink Shuhua milk that decomposes lactose to a certain extent. You can also drink some yogurt to reduce lactose intolerance.

In addition, many people do not know the difference between pure milk and fresh milk . In fact, both use fresh milk as the main raw material. The difference is that after pasteurization, fresh milk can retain milk nutrition to the maximum extent, that is, the shelf life is shorter, while pure milk is sterilized at high temperature to extinguish microorganisms. The shelf life will be longer, that is, the nutrients will be lost more. Fresh milk is indeed superior to pure milk in terms of freshness and nutrition, but both are healthy milks.

However, some people prefer freshly squeezed, unsterilized raw milk , which is more nutritious, but scientists have found that the nutritional value of raw fresh milk is not significantly different from that of heat-sterilized milk.

Raw fresh milk does taste better, but it is not sterilized, and it also poses a greater food safety risk . Especially people with low immunity who drink raw fresh milk are more likely to be infected with bacteria such as Brucella , so it is recommended that you do not drink it directly. Raw milk, including fresh milk.

Three, these are not "milk", we must recognize

When you go to the supermarket, you may find that there are many types of milk on the shelves, all kinds of breakfast milk, milk drinks, etc. Are these milk? No, they are not!

1. Breakfast milk

The ingredients of breakfast milk include water, raw milk, white sugar, fruit, etc. The content of water is even more than that of milk, so breakfast milk is more like a milk drink with added water and sugar. It is not pure milk, and it cannot be completely In lieu of normal breakfast.

2. Lactic acid bacteria drink

Lactic acid bacteria beverages are easy to be mistaken for yogurt. It is just a "milk-containing beverage". The ingredients are mainly additives such as water, dairy products and white sugar. The protein content needs to be ≥1%, while the protein content of pure milk needs to be ≥2.9%. Therefore, lactic acid bacteria The drink is more of a drink than milk or yogurt.

3. Vegetable protein drinks

Plant milk is made from plants or products with a certain protein, and various food accessories are added at the same time. The appearance and taste are similar to milk, but it cannot be equated with milk. It should be classified as a plant protein drink.

Common ones, such as soy milk, nut milks such as almond milk and walnut milk, grain milks such as oat milk, quinoa milk, and coconut milk are all plant milks.

Fourth, how to drink milk every day?

It is well known that milk is rich in nutrients and encourages everyone to drink more milk. In the latest "Dietary Guidelines for Chinese Residents", it is emphasized that the daily intake of various milk and dairy products by residents should be 300-500g , while the previous version was It is recommended to "300g of liquid milk per day", obviously the demand for national milk has increased.

As for the time to drink milk, there is actually no absolute . Generally speaking, individuals drink as much as they want. To put it simply, it doesn’t matter when you drink it, what matters is whether you drink enough or not.

Also, some people like to drink hot milk, but they are worried that heating milk will destroy the nutrition of milk.

Because the calcium in milk will not change due to heating , some proteins will become milk skin after heating, but this does not mean that milk loses all nutrients, so milk can be heated, and it is recommended that you use low-temperature heating methods , such as water insulation or heating heating.

Milk does not cause cancer, nor does it have hormones or preservatives. If conditions permit, it is recommended that everyone drink more milk. Everyone must remember the advertisement, "A pound of milk a day strengthens the Chinese people"!
