Do you have to drink hot milk at night, is it okay to be cold?

It is better not to drink cold.

According to the data, milk should not be drunk on ice, because after the milk is frozen, the fat and protein in the milk are separated, the taste is obviously lighter, and the nutrients are not easy to be absorbed; There are also some sources that milk should not be boiled, and if the temperature is too high, the protein in the milk will change from a sol state to a gel state, resulting in sediment and affecting the quality of dairy products. So, what exactly should be the best temperature to drink milk?

According to Zou Shurong, deputy director of the nutrition department of the Shanghai Municipal Center for Disease Control and Prevention, dairy products have a variety of forms, according to China's food industry standard system, can be divided into liquid dairy products, milk powder, milk fat, condensed milk, cheese, ice cream and other dairy products and other seven categories, the current liquid dairy products and milk powder products on the market are the largest consumer products in China. According to the degree of sterilization, liquid dairy products that have not been blended can be divided into raw milk, sterilized milk and sterilized milk. Raw milk is not yet popular in the Chinese market because it has not undergone any sterilization and sterilization treatment; Pasteurized milk, but the bacterial stalks in it are not inactive and must be transported and stored at 0 4 degrees; There are two kinds of sterilized milk, one is UHT milk, which is aseptically filled after the milk is sterilized by ultra-high temperature instantaneous sterilization at 135 degrees above 1 2 seconds, and the other is to keep sterilized milk, which is to keep the milk canned and sealed first, and then kept above 110 degrees for 15 40 minutes of sterilization procedures to reach the commercial sterility level, which can be stored at room temperature for more than 6 months.

Pasteurized and sterilized milk is best served fresh, ready to drink within the expiration date, and does not have to be heated before drinking. If you have a stomach that is not suitable for eating cold or like to drink hot milk, you can heat the milk properly, but the temperature should not be too high, not boiled, so as not to cause the loss of nutrients, it is generally recommended to heat it to below 75.

It is not good to drink cold milk in winter.

Reasons: 1. Cold milk will cause gastrointestinal contraction, which makes the digestion and absorption of milk poor, so that the health purpose of drinking milk cannot be achieved;

2. Drinking cold milk before meals at night in winter will affect appetite and lead to nutritional deficiencies. Drinking cold milk immediately after meals will reduce gastric acid secretion, reduce the immune function of the digestive system, and cause intestinal diseases such as enteritis;

3. Due to their own reasons, some people have primary lactose discomfort, which is manifested as nausea, bloating, abdominal sound, diarrhea and other discomforts after drinking ordinary fresh milk, lactose discomfort makes people unable to fully absorb the Yingzhaoyan components in milk, and milk will aggravate this reaction when drinking cold, making milk more difficult to digest and absorb.

When drinking milk, it is best to drink ambient milk, leave refrigerated milk for a while before drinking, or choose fermented milk products that are easier to absorb.

The correct timing of drinking milk is advisable to drink before going to bed, which not only has the effect of calming the nerves, but also has the effect of protecting the stomach and intestines.

It is not good to sleep at night with cold milk. Because drinking cold milk will cause abdominal pain and bloating, not only can not improve the quality of sleep, but also may be counterproductive and affect normal rest.

Therefore, when drinking milk at night, it is best to choose to heat it, which can ensure the taste and texture at the same time, and also maximize the role of milk to assist sleep.

The effects of milk are usually as follows:

1. It can supplement rich calcium for the body, and has a very obvious role in preventing osteoporosis and preventing soreness in the waist and knees.

2. It can supplement high-quality protein for the body, and it also plays a very strong role in improving the body's immunity and muscle strength.

3. From the perspective of traditional Chinese medicine food therapy, it can moisten and moisten dryness, and for people with dry mouth and thirst caused by injuries, appropriate consumption of milk can relieve dry mouth and thirst through hair growth liquid.

When drinking milk, it should not be drunk on an empty stomach, which will affect the absorption of nutrients from milk. Milk cannot be drunk with tea, which is rich in calcium ions, and the tannic acid in tea can hinder the absorption of calcium ions in the stomach and intestines.

Drinking milk at night is good for rest and sleep. It is best to drink milk at night, because milk contains a biochemical that can make people tired and drowsy, as well as trace amounts of morphine, these substances have a certain sedative and hypnotic effect, especially L-tryptophan It is the main raw material for the brain to synthesize hydroxyxton, and serotonin plays a key role in brain sleep.

It can temporarily inhibit the brain's thinking activities, so that people want to sleep, and there is no ***, and the milk sticks to the stomach wall to absorb it, and the calcium in the milk can also clear the tension, so it is more beneficial to the sleep of the elderly, so it is good to drink milk at night, which is conducive to people's rest and sleep.

Drinking milk before going to bed is conducive to the absorption and utilization of calcium. Most of the calcium consumed at dinner is absorbed and utilized by the body before going to bed. After sleeping, especially after midnight at night, the level of calcium in the blood will gradually decrease, the decrease of blood calcium promotes the hypersecretion of parathyroid glands, and hormones act on bone tissue, so that a part of the calcium salt in bone tissue is dissolved into the blood to maintain a stable balance of blood calcium.

This dissolving effect is the body's self-regulating function, and over time, it can become one of the causes of osteoporosis. Drink milk before going to bed at night, the calcium in the milk can be slowly absorbed by the blood, and the blood calcium has been replenished and balanced throughout the night, so it is no longer necessary to dissolve the calcium in the bones, preventing bone loss and osteoporosis, so it is good to drink milk before going to bed.
