Milk contains a lot of preservatives, toxic and carcinogenic? What you really want to drink less is these 3 kinds of 'fake milk'

"Dad, I bought several cartons of milk on the Internet. Remember to drink one bottle every day. I fell and broke a bone before I woke up." Xiao An came home from a rare holiday, but found that his old father Last month, he fell and suffered a broken bone, so I plan to make him drink more milk to supplement calcium.

As a result, my father refused without thinking, "Hurry up and return it! I don't drink milk. It is said on the Internet that milk is full of preservatives. Drinking too much is poisonous and causes cancer . I would rather take calcium tablets than milk."

"Which 'brick house' did you listen to? Those so-called experts are just tricking you old people and asking you to buy their calcium supplements. I don't care, anyway, you will have to drink a bottle every day. ." After that, Xiao An went out to play with her best friend with her bag.

Milk is high in calcium and rich in nutrients, and is called "white blood". However, in recent years, there have been many claims that "milk has a long shelf life because of the addition of preservatives", "milk has a lot of hormones, and drinking it will cause cancer." "What is the truth?

1. Milk has a long shelf life because there are many preservatives?

The normal temperature milk we usually buy has a shelf life of 6-9 months. Does that mean that a lot of preservatives are added in it, so the shelf life is so long?

First, the shelf life of food has nothing to do with preservatives. The factors that determine the shelf life of food are mainly internal factors such as the water content, salt content and sugar content of the food, as well as external factors such as the production process and packaging of the food.

The long shelf life of normal temperature milk is due to the use of high temperature sterilization and vacuum packaging during production , which isolates milk from oxygen.

Plus, virtually all plain milk is preservative-free .

Whether it is normal temperature milk, refrigerated milk, domestic milk or imported milk, the sterilization processes used are pasteurization and high temperature sterilization . of.

Second, milk contains a lot of hormones, drinking too much will cause cancer?

It is rumored on the Internet that milk contains hormones, and there are even claims that cows rely on hormones to produce milk, and then there are claims that eating too much food containing hormones will cause cancer, so milk, hormones, and carcinogenicity are the three. Equals are drawn.

Does milk really contain hormones? Does drinking too much really cause cancer?

In 2020, a study in the International Journal of Epidemiology noted that drinking milk may increase the risk of breast cancer .

The study selected 52,795 North American women with an average age of 57.1 years (none of whom had previously had cancer) as participants. The researchers followed the participants for 7.9 years, during which a total of 1,057 new cases of breast cancer were recorded.

The researchers found similar results for whole, low-fat, and skim milk :

• Drinking only 1/4-1/3 cup of milk a day increases the risk of breast cancer by 30%;
• Drinking 1 glass of milk a day increases the associated risk by 50%;
• Drinking 2-3 glasses of milk a day increases the risk by as much as 70%-80%.

In this regard, registered dietitian Fan Zhihong said that it cannot be concluded that milk will cause cancer based on the results of a study alone .

First of all, the respondents of this study are middle-aged and elderly women living in the United States, and there are certain limitations in age and region, which may affect the results of the study. Moreover, the scientific community has not reached a consistent conclusion on the relationship between milk and cancer.

The reason why the relevant research results are inconsistent is mainly because the interviewed population (including age, dietary habits, etc.), analysis methods, sources of dairy products, and varieties of dairy products in different studies are different to varying degrees.

More importantly, milk is rich in nutritional value and has many benefits for people's health .

Milk is rich in nutrients such as protein and calcium, and its utilization value and human absorption rate are also very high. Drinking milk has many clear nutritional benefits, including providing the body with basic energy, helping to increase bone density and boosting immunity.

A study published in The Lancet found that higher intake of dairy products was associated with a lower risk of cardiovascular disease and mortality. Therefore, the benefits of drinking milk to human health outweigh the disadvantages .

3. These 3 kinds of fake milk really need to be drunk less!

There are many milk products on the market, such as room temperature milk, pasteurized milk, breakfast milk, whole milk, low-fat milk, skimmed milk, etc. It turns out that some of these milk products turned out to be "fake milk", which is not only nutritious, but may also be a drag on health!

1. Breakfast milk

The ingredients list of breakfast milk includes raw milk, water, white sugar, solid malt extract and various food additives. Strictly speaking, breakfast milk is not actually milk , and it may bring extra burden to the body for a long time.

2. Modified milk

Although the raw milk content of modulated milk is more than 80%, its ingredients also include water, white sugar and edible flavors, which are also not milk. Especially modulated milk with added sugar and flavor is unhealthy .

3. Milk beverages

The main ingredients of milk-containing beverages are milk, water and white sugar. The top ingredient list is water. Some milk-containing beverages will be prepared by adding various sweeteners. The essence is high-grade sugar water .

In addition to being high in sugar, dairy-based beverages are also much lower in calcium than plain milk.

In addition to buying the right milk, it is also important to drink the right milk.

Healthy people and children - whole milk, not only nutritious, but also very delicious.

People who drink milk every day - pasteurized milk, has the best nutrition and taste.

People who lose weight and dyslipidemia - low-fat milk, help weight control.

Lactose intolerant people - low-lactose milk or lactose-free milk.

It should be noted that people with diarrhea, gastric ulcers and patients with cholecystitis are not recommended to drink milk, otherwise it will easily increase the burden of digestion.

Overall, milk is rich in nutritional value, and if you are not into milk or lactose intolerance, drinking 1-2 glasses of milk a day is safe and healthy. In addition to drinking milk, you should also eat more other foods to ensure a balanced nutrition.
