But in China, milk doesn't seem to be "hated" by most people, and there are many misunderstandings about milk on the Internet.
Today, we will help you summarize 9 misunderstandings about drinking milk and "rehabilitate" milk ~
Misunderstanding 1
Drinking milk causes cancer.
The rumor that milk causes cancer actually starts from 20 13 and will be mentioned every one or two years. It is said that IGF- 1 (insulin growth factor) and tyrosine in milk can cause cancer.
Truth:
The recommended milk intake (300 grams per day) in the current dietary guidelines will not increase the risk of cancer.
Tyrosine carcinogenesis is an open misinterpretation of an American experiment, which cannot prove that milk is carcinogenic.
Moreover, there is very little IGF- 1 in milk, so it is necessary to drink nearly 1L of milk for a long time every day to reach the so-called risk value. The processing and heating of milk will also inactivate most IGF- 1.
There is almost no IGF- 1 in milk.
Heat to inactivate it.
Misunderstanding 2
Calcium supplementation in vegetables is better than milk.
Truth:
It is true that some vegetables, such as shepherd's purse, contain more calcium than milk, even three times as much as milk, but their absorption rate is not as good as milk.
It is unfair to simply compare calcium content. Because milk is liquid, it is relatively easy to drink enough milk, but it is not easy to eat nearly a catty of vegetables every day if you rely entirely on vegetables to supplement calcium.
In addition, many vegetables also contain oxalic acid, which may affect the absorption efficiency of calcium. In short, both milk and vegetables should be eaten, and it is easier and more efficient for milk to supplement calcium.
Misunderstanding 3
People in China are not fit to drink milk.
Some people come to this conclusion because China people are more prone to lactose intolerance than westerners, which leads to diarrhea and bloating after drinking milk.
Truth:
People in China should also drink milk. In fact, lactose intolerance will not affect the absorption of nutrients in milk too much. Considering the rich nutritional value of milk, even people who are lactose intolerant are advised to drink milk.
The ways to deal with lactose intolerance are:
Drink a small amount many times.
Within 200ml each time.
When drinking milk
Eat some other food, too
Buy drinks from the market
Zero lactose milk
Misunderstanding 4
"Hormones" have been added to milk.
People are mainly worried about adding two hormones, growth hormone and sex hormone.
Truth:
Growth hormone is legally added to foreign milk, but it is forbidden to add growth hormone to domestic milk. Sex hormones are meaningless for milk production and will not be added.
In some countries, it is legal to use "growth hormone" to increase milk production.
Both the World Health Organization (WHO) and the US Food and Drug Administration (FDA) believe that it is safe to use the prescribed dose of growth hormone. Growth hormone is banned in China.
Foreign milk
Growth hormone legal addition
Domestic milk
Growth hormone-free
Adding estrogen and other "sex hormones" will inhibit the milk production of dairy cows, and no one will deliberately add them. So we don't have to worry about hormones in milk.
Myth 5
Preservatives are added to milk with long shelf life.
The shelf life of milk in the market is different, so many people are worried about whether preservatives have been added to the milk with long shelf life.
Truth:
The shelf life of milk has nothing to do with preservatives.
There is no preservative in the ingredient list of almost all pure milk on the market, and the shelf life of milk mainly depends on the sterilization method when handling dairy products.
pasteurization
Ultra-high temperature sterilization method
Germs can be killed at low temperature (60℃~85℃) and stored in cold storage for 2~7 days.
Milk can be instantly heated to 135℃~ 150℃ for several seconds, which has higher sterilization efficiency and can be stored at room temperature for more than 6 months.
Myth 6
Milk sterilized at high temperature has no nutrition.
Truth:
Sterilizing milk at high temperature does destroy some B vitamins. But protein and calcium are the most important nutrients for drinking milk, and these two nutrients will not be lost because of high temperature.
So if the milk you buy can't be refrigerated in time or drunk as soon as possible, you can buy high-temperature sterilized milk.
Misunderstanding 7
Plant milk is healthier than milk.
Vegetable milk refers to beverages made of beans and nuts such as soybean milk and almond milk. Many people judge from their own life experience that plants are healthier than animals. But this is not the case.
Truth:
The contents of protein, vitamins, calcium and other nutrients in plant milk are lower than those in milk. Only it contains less saturated fat and is better than milk.
Moreover, the general plant dairy products will add sugar, which will increase the daily sugar intake of the human body. So instead of drinking plant milk, it is better to eat beans and nuts directly.
Vegetable milk
Less saturated fat
But the sugar is high.
milk
eutrophy
And the sugar content is low.
Misunderstanding 8
Drinking milk on an empty stomach is not good for the stomach.
Some people will have diarrhea symptoms when drinking milk on an empty stomach, so they think that drinking milk on an empty stomach is not good for the stomach.
Truth:
In fact, as long as it is not too cold, drinking milk on an empty stomach has no effect on the stomach itself. In most cases, drinking milk on an empty stomach will not cause discomfort. Most gastrointestinal discomfort is due to lactose intolerance.
Generally speaking, milk can be drunk at any time. People who are lactose intolerant can adjust themselves according to their own feelings.
Patients with digestive diseases such as gastric ulcer and gastroesophageal reflux should follow the doctor's advice if they want to drink milk.
Myth 9
High calcium milk has better calcium supplement effect.
Many dairy products will add extra calcium to pure milk to increase the calcium content in milk.
Truth:
But in fact, the fortified calcium used in this kind of "high calcium milk" is mostly calcium agent such as calcium carbonate, and its absorption rate is far less than that of the original milk calcium in milk.
Therefore, for calcium supplementation, high-calcium milk is not more efficient, so everyone chooses voluntarily.
abstract
1, drinking milk will not cause cancer;
2, calcium supplementation is most recommended to drink milk;
3. Lactose intolerance should also eat dairy products;
4. No hormones will be added to qualified milk;
5, pure milk will not have preservatives;
6, high-temperature sterilized milk (normal temperature milk) is as nutritious;
7. Eating beans and nuts directly is better than drinking plant milk (coconut milk, almond dew);
8, drinking milk on an empty stomach does not hurt the stomach;
9. The calcium supplement effect of high calcium milk is not much different from that of ordinary milk.
In a word, milk is indeed a kind of food with high nutritional density. Taboos are not as many as everyone thinks. Although many people in China are lactose intolerant, it does not mean that they refuse milk. The advantages of drinking milk definitely outweigh the disadvantages! ! !
