Milk is a common healthy drink, and many people have the habit of drinking milk every day. However, drinking milk is a technical job, and drinking it incorrectly may greatly reduce nutrition.

Common mistakes in drinking milk

For milk, we should not only choose, but also drink. The following six aspects need special attention:

0 1

Avoid long cooking

For healthy people, it is enough to drink normal temperature milk.

If you have the habit of drinking hot milk, you can soak it in warm water or heat it with central heating.

Because when the milk is heated above 70 degrees, some protein and vitamins will denature and precipitate, which will cause the waste of nutrients to some extent.

The "milk skin" that appears after we heat milk is actually one of the manifestations of protein's degeneration.

02

Don't drink iced milk.

Milk should not be stored by freezing, because freezing will denature protein in milk, and the fat will be layered. After thawing, protein and fat will precipitate and solidify, which is not conducive to human absorption, but also greatly reduces the value of milk.

Therefore, ordinary milk should be stored at room temperature away from light. Don't covet hot drinks or chilled fresh milk.

03

Don't use milk to "send medicine"

Nutrients such as protein and calcium contained in milk can combine with some metal ions in drugs, which may affect the release of drug efficacy and may cause toxic reactions.

It is recommended not to drink milk before and after taking the medicine 1~2 hours, let alone take the medicine with milk.

04

Don't drink milk as water.

Milk can provide high-quality protein and calcium to human body, but at the same time, the fat content is not low. If it is ingested too much, it will cause excess energy.

Moreover, protein's excessive intake will also increase the burden on organs such as kidneys, and even the incidence of kidney calculi is high in western countries who drink a lot of milk in the world.

According to the dietary guidelines for China residents, adults should consume 300 grams of milk or a considerable amount of dairy products every day.

05

Don't always drink low-fat milk

For most people, no matter the nutrition or taste, whole milk is better.

Skim milk removes fat from milk and some fat-soluble vitamins such as vitamins A, D and E, which is only suitable for the needs of some people, such as people who lose weight and people with cardiovascular diseases who need to control their blood lipids.

06

Lactose intolerance, don't "drink hard"

Some people are intolerant of lactose, and may have abdominal distension after drinking milk, and even diarrhea after drinking too much.

In this case, you can choose to start with a small amount, drink 50 ml or 100 ml a day first, and gradually increase the amount when you get used to it.

Or choosing some special milk products can also relieve discomfort, such as low lactose milk.

If the symptoms are really serious, replacing milk with yogurt can effectively avoid this situation.

Taboo to drink milk

0 1

Taboo 1: Drink milk on an empty stomach.

In fact, this is not a taboo for everyone. In our life, it is ok for quite a few people to drink milk on an empty stomach.

But why should we emphasize this point?

This is because milk often contains a lot of lactose, and lactose can only be absorbed and utilized by the body after decomposition, which requires the participation of lactase in the human body.

If there is no lactase in the small intestine or its activity is low, the lactose in milk can not be decomposed in time and will directly enter the large intestine. These lactose will produce gas and acid under the action of bacteria, which will cause human discomfort.

According to statistics, more than two thirds of adults in China lack lactase.

In other words, a considerable number of people in China will feel uncomfortable after drinking milk on an empty stomach.

Therefore, you can also pay attention to observe whether you belong to this kind of people. If you have related problems, it is recommended to drink milk with some food, and then sip slowly to give your body some time to digest.

02

Taboo 2: Drink with tea and coffee.

Milk is rich in calcium ions, and tea contains tannic acid. The reaction between calcium and tannic acid produces insoluble calcium salts, which will affect the absorption of calcium. Caffeine in coffee is also a strong decalcifier.

According to statistics, people who drink tea or coffee for a long time have a higher probability of osteoporosis, which is also related to the influence of drinking tea or coffee on calcium absorption.
