Is the modified atmosphere packaging machine good for keeping fresh?

People take food as their heaven. Regarding food nutrition, people generally believe that "it is better to eat two-legged food than four-legged food, and it is better to eat two-legged food without legs." , Some people infer that the fewer animal legs, the higher the nutrients that are beneficial to the human body, and the nutritional value of fish without legs is very high. Is this really true? And listen to what nutrition experts have to say. How to choose a modified atmosphere packaging machine for fresh meat?

Not much difference in protein

"From the analysis of nutritional components, the difference in protein content of these meats is not very big." explained Dr. Li Yuanbi from the Nutrition Department of Binhu Hospital.

"Four-legged" refers to livestock such as pigs, cattle, and sheep. Because of the red meat, people usually call it "red meat"; "two-legged" refers to poultry such as chickens, ducks, and geese. Sex is called "white meat". In 100 grams of meat, the protein content of "red meat", "white meat" and fish is about 20 grams, 19 grams and 17 grams respectively, which are almost the same.

In terms of fat content, the saturated fatty acid content of pork is slightly higher, which will cause cardiovascular burden and produce three high risks. However, "red meat" such as pork, beef and mutton also has its advantages. Due to the relatively high content of heme, iron and B vitamins, patients with iron deficiency anemia can consume more. Chicken is high in protein and low in fat. If it is cooked properly, chicken neck, buttocks and other parts are discarded. If only chicken is considered, the nutrition is more balanced and the price is moderate, so it is very popular among the people. Fish meat is high in protein, but also contains high levels of polyunsaturated fatty acids that are beneficial to human health, especially deep-sea fish, which are rich in omega-3, polyunsaturated fatty acids, EPA, DHA and other nutrients that promote brain development. From the point of view of enhancing physical fitness, fish is indeed a healthy food.

Prioritize and balance

According to the principles of scientific diet, simply from the perspective of the nutrients contained in different meats, it is not unreasonable to "eat a four-legged one rather than a two-legged one, and two-legged one is better to eat one without legs", but Dr. Li Yuanbi emphasized that life It is not advisable to pursue a balanced diet and blindly pursue nutrition instead of a partial eclipse.

Different groups of people can give preference to and consume more foods that are beneficial to health according to their actual conditions. For example, children who are still in the stage of growth and development should eat more brain-healthy fish. People with iron deficiency can eat more pigs. Lean meat, calcium deficiency in the body needs to be supplemented with beef, pork lean meat and fish. However, it is important to ensure a balanced nutrition while giving priority to eating more in moderation.

For a long time, many people have a misunderstanding in the dietary structure: eating more protein is good for health. Generally speaking, the high-quality protein in the diet of urbanites is enough, but many people are still keen to supplement nutritional products such as soy protein. As everyone knows, eating too much protein will increase the burden on the kidneys. At the same time, people should get out of the misunderstanding that pork is the main meat, and can choose other meats, which is good for a balanced diet.

Li Yuanbi reminded that a scientific diet should have a balanced structure and nutrition, and the ratio of protein, fat and carbohydrates should be reasonable. The energy provided by carbohydrates should account for about 60% of daily energy consumption, fat accounts for about 25%, and protein accounts for about 15%.

No need to blindly seek miscellaneous

Many people know that food diversification is the basis of a balanced diet, and the healthy concept of "eating mixed food" is indeed justified. But doesn't it mean "the more you eat, the better"? Li Yuanbi said that there is no need to blindly pursue "miscellaneous" in life, and we cannot blindly consider the number of food varieties and ignore the dietary structure.



Studies have shown that humans need to consume more than 40 nutrients through food every day to meet the needs of the body. There are many kinds of foods in nature, and the nutrients contained in various foods are not exactly the same. Specifically, each food contains at least one nutrient, and each food contains different types and contents of nutrients. Except for breast milk, no natural food can provide all the nutrients the human body needs. Therefore, our daily diet must be composed of a variety of foods. Only by choosing as many varieties of food as possible can we obtain sufficient and balanced nutrients and achieve the purpose of promoting health. However, food intake is not the more complex the better. For people with gastrointestinal problems and indigestion, excessive intake of different types of food can increase the burden on the stomach.

The dietary fiber rich in coarse grains can stimulate intestinal peristalsis, prevent constipation, improve intestinal flora, promote the growth of probiotics, shorten the residence time of harmful substances in the feces in the intestinal tract, and prevent intestinal tumors. In addition, dietary fiber can delay the digestion and absorption of carbohydrates, which is beneficial to control blood sugar. It can reduce the body's absorption of fat, help prevent hyperlipidemia, increase satiety, and help control weight. Middle-aged people eat more whole grains and supplement dietary fiber, which can effectively prevent "wealthy diseases" such as hyperlipidemia. With the improvement of living standards and the enhancement of people's health awareness, corn flour, millet, wheat bran, buckwheat, mung bean and other coarse grains have returned to people's lives, and are favored by more and more citizens who are pursuing a combination of thickness and size and a reasonable diet . However, coarse grains are not suitable for everyone, such as adolescents in the growth and development period, people with poor gastrointestinal function, people with calcium and iron deficiency and other trace elements, people with digestive system diseases, people with low immunity, People with heavy physical labor, the elderly and children are not suitable for eating too much grains.

In daily life, rice can be made into second or third rice, rice with buckwheat, oat or brown rice, etc., or you can add some miscellaneous beans, red beans, broad beans or black beans to the rice, not only to achieve a variety of varieties, but also grains and beans. The amino acids in the class can also complement each other well, so that the utilization rate of the protein is very large. The same is true for porridge. You can put more whole grains or beans in the multigrain porridge. Noodles, steamed buns, etc. can be used this method. But it should be noted that coarse grains should be controlled at one-third of the staple food, not more than one-half, especially if there are elderly and children at home, not only should the amount of coarse grains be controlled, but also soft and rotten before Will not hurt the stomach.

Many friends don't understand this. It is actually unreasonable to blindly follow the trend after listening to people around them say "the more mixed the food, the better" and "the more coarse grains you eat, the better your health". Li Yuanbi reminded that for some crazy health concepts, everyone must carefully analyze and identify them, or consult doctors and professionals, and not blindly adopt and follow them, so as not to cause damage to the body.
