Do you drink the right amount of milk from 80% people?
origin: China economic network
is well known, dairy products are the important food to improve the dietary structure and improve the physical quality of the people. Goods. Recently, the "2017 Chinese milk habit survey" shows that nearly 80% people do not drink enough milk. One of the reasons leading to inadequate intake of dairy products in China is the lack of knowledge about milk and nutrition.
when we buy milk, we find that there are many kinds of milk in the market, such as pure milk, high calcium milk, children's milk, diastolic milk, and fresh milk sold on the Internet, and these kinds of dairy products are also different. Which kind of milk is more nutritious? How do consumers choose? Next, China economic network health channel to take you together to understand.
which kinds of milk are higher
pure milk
Recommendation Index of most people:
pure milk is the best choice for most people, it contains a variety of nutrients, such as fat, protein, vitamin, calcium, etc. It is very beneficial to the human body. According to sterilization, milk can be divided into normal milk and pasteurized milk. The former is to milk the milk after super high temperature sterilization. It is filled with six layers of aseptic materials, without refrigeration, and the shelf life is as long as several months. The latter is killing bacteria at about 80 degrees Celsius, requiring cold storage, and the shelf life is -8 days. Compared with pasteurized milk, normal temperature milk will lose some heat sensitive vitamins, and flavor is also worse. But people drink milk mainly for protein and calcium, so there is almost no difference between pasteurized milk and normal temperature milk.
Gao Gainai:
calcium supplement does not have to be better than normal milk
Recommendation Index:
the so-called high calcium milk, according to the national standard GB28050-2011 "prepackaged food nutrition label general rule", the calcium content reaches or higher than a certain value (120mg/10). 0ml) milk. In general, the calcium content in natural milk is between 80-100mg/100ml, and the high calcium milk is also common milk. Only when production is added, some extra calcium will be added. A survey of high calcium milk shows that many products with high calcium milk have no big difference in calcium content compared with ordinary whole milk or ordinary skimmed milk. Therefore, calcium supplements do not have to rely on high calcium milk.
low fat or skimmed milk
suitable for obesity, hyperlipidemia, and elderly people to eat
Recommendation Index:
skimmed milk, which is the product of removing part of the fat in milk by centrifugation. The whole fat milk has a fat content of about 3%, low fat milk (semi skim milk) contains 1.0-1.5% fat, and skim milk contains 0.5% fat. Skim milk has the characteristics of low fat and low calorie, which is suitable for obesity, hyperlipidemia and elderly people.
vitamin A, D, E mainly exist in the fat part of milk, but the fat in the skimmed milk is less, and the nutrition is not as full as the whole milk, and the taste is relatively weak. Vitamin D combined with calcium helps to reduce the recurrence rate of intestinal polyps.
children's milk
Recommendation Index:
children's milk is actually a kind of dairy products. In general, many kinds of sugar, such as white granulated sugar, polyglucose, oligomeric fructose, are added. In addition, there are many additives such as food flavors. Experts say the obesity rate of children in our country is on the rise, so it is not an important thing to encourage children to drink milk with a large amount of sugar for a long time. In addition to sugar, children's milk additives have a certain impact on the growth and development of children, and will affect the appetite of children, resulting in anorexia and other symptoms. In addition, although children's milk claims to add a variety of nutrients, there is no factual evidence to prove how useful it is for children's growth. If you want to supplement your child's nutrition, the best way is to drink ordinary bags of milk and eat more fruits and vegetables.
breakfast milk
high price, low nutrition
Recommendation Index:
breakfast milk, which is actually a drink added to other ingredients such as water and sugar. When adding other ingredients in milk, the original nutrients in the milk will be reduced, and the nutritional density of milk will also be reduced. The protein content of ordinary milk should be 3%, and the protein content in the so-called breakfast milk, red jujube milk and walnut milk has been reduced, because the added ingredients "drive away" the nutrients in the milk.
milk sugar
Recommendation Index:
milk contains lactose. After lactose enters the body, it needs lactase to decompose. Only after lactose is decomposed, the monosaccharide can enter the blood through the wall of the small intestine. The body is absorbed by the body. If the human body does not have this enzyme, the lactose will not be decomposed after entering the small intestine and then directly into the large intestine. If the bacteria in the large intestine act on lactose, it will produce acid and produce gas and cause diarrhea. Shu Hua milk is the decomposition of lactose in milk to a certain extent, so that the tolerance of milk becomes better. If people do not have lactose intolerance, it is not necessary to choose Shuhua milk, because lactose in milk can promote calcium absorption.
raw milk
no sterilization and sterilization treatment, can not guarantee the safety
Recommendation Index: not recommended
"raw milk" is unbactericidal, homogenization and other processing of raw milk. Some raw milk can not guarantee the safety of raw materials because they are not sterilized, which may affect the human body after drinking. In the raw milk that has not been processed, the most common microorganisms are Staphylococcus aureus, Escherichia coli, tubercle bacillus and Brucella. Even if ordinary people disinfect the raw milk, the containers, such as pot and bowl, may also be contaminated by bacteria. If they are not treated in time, it is easy to cross infection when cooking other foods. Studies have shown that there is no significant difference between raw milk and pasteurized pure milk in nutrition and human health function.
what is the daily intake of milk per person?
according to the China economic network health channel, the Chinese residents' dietary guidelines put forward 300 grams of milk per day per person per person or a considerable amount of dairy products per person in China. "Sooner or later, each bag of milk or a bag of milk plus 100 milliliters of yogurt, so that we can achieve the recommended intake." Chen Wei, chief physician of enteral nutrition department of Peking Union Medical College Hospital, said.
Dr. Zhong Kai, deputy researcher at the risk exchange department of the national food safety risk assessment center, suggested that consumers should buy regular brands at the supermarket when they buy their dairy products, and the pasteurized milk and super high temperature milk sold in the supermarket can meet the needs of daily people for milk protein and calcium. Large difference.
