Speaking of delicious food, there are many more in China.
Like what steamed lamb, steamed bear paw, steamed deer tail, roasted duck, roasted chicks, roasted goose, marinated pig, marinated duck, sauced chicken, bacon, pine flower belly...
In these foods, no matter which bite you like, you can't do without the word "meat".
It is enough to see how deep Chinese preference for meat is.
But why is meat so delicious?
<h1 class="pgc-h-arrow-right" data-track="71" >. </h1>
Delicious meat and the unique flavor of meat are inseparable, the protein, fat, carbohydrates and other substances in the meat in the cooking and heating process, a chemical reaction called Millard will occur, generating a series of flavors and flavors, and these substances will give us a "delicious" feeling. Next, let's talk about what these two substances are.
When we eat meat, different meats may taste different feelings such as sour, sweet, bitter, salty, fresh, etc., why do we have so many feelings when eating meat?
This is because the flavor substances contained in meat, such as inorganic salts, free amino acids and small peptides, nucleic acid metabolites, reducing sugars, etc., are all one of the taste substances. It is also the existence of these substances that enriches the taste level of meat food, which is also one of the reasons why meat is delicious.
Secondly, when cooking meat, often the kitchen is filled with an intoxicating meat aroma, this aroma is pleasant, appetite is open, and the source of meat aroma is that meat in the heating cooking process, through the Millard reaction, lipids and thiamine thermal degradation and other chemical reactions to produce a variety of volatile substances, it is these flavor substances that make meat have a unique meat flavor, so that people love, there are vegetables instead of the status.
<h1 class="pgc-h-arrow-right" data-track="70" > two, red meat, poultry, fish, which meat is the most nutritious? </h1>
The common meat on our market can be roughly divided into three kinds, namely red meat, poultry meat, and fish meat, but at present, doctors and organizations tell us that red meat has certain carcinogenicity, but is this really the case? Which of these 3 meats is more nutritious?
• Red meat
Red meat literally means red meat, which is actually red meat before cooking, like pork, lamb, and beef that are often eaten in life.
1. The nutritional value of red meat
(1) Protein
Different meats correspond to different protein content, and each 100g of red meat contains about 17-25g of protein.
These proteins are more in line with the types of amino acids needed by the human body, and have a better absorption effect than plant proteins, which can better meet the needs of human cells and tissues for protein amino acids.
Protein is the material basis for maintaining life, is the main carrier of life activities, the growth and development of the human body, the recovery of post-illness protein demand is greater, eating meat has become a better choice.
(2) Iron elements
The reason why the blood is red, the root is the existence of iron, which also shows the importance of iron for the human body, is the essential trace element for human blood production and oxygen transportation, and the consequence of serious iron deficiency is iron deficiency anemia.
Red meat is rich in iron, about 3mg of iron per 100g of red meat, which is an important source of iron supplementation for the human body.
(3) Vitamin B12
Vegetables and fruits basically do not contain vitamin B12, meat has become the main natural source of vitamin B12, vitamin B12 intake to inhibit anemia, protect the brain nerves to produce a vital role, but also to help metabolism, so as to escort the body's energy supply for high-intensity exercise.
(4) Zinc element
It is said that children should supplement zinc, zinc can help children develop and grow, but also one of the components of insulin, and together with other nutrients may also strengthen the immune system. Red meat is relatively rich in zinc and can meet daily needs.
2. Red meat is not recommended to eat more, and it is important to control the amount
Red meat has a high fat content, and a high proportion of saturated fatty acids, saturated fatty acids are less easily digested and absorbed by the human body, the calorie content is high, and excessive ingestion is easy to accumulate residual, causing obesity.
Obesity can lead to an increase in human blood lipids, causing lipid balance and inducing cardiovascular disease. China's dietary guidelines point out that the amount of meat 40-70g per day for adults is the most ideal.
• Poultry meat
Poultry meat usually refers to the meat of poultry we raise, there are also wild poultry meat, generally often eaten chicken, duck, goose and so on belong to poultry meat.
1. What are the nutritional values of poultry meat
Poultry meat usually refers to the meat of poultry we raise, and the chicken, duck, goose, etc. that are commonly eaten are poultry meat.
In general, the protein content of poultry meat is not much different from red meat, poultry meat contains about 10-21g of protein per 100g, of which chicken is more prominent, and each 100g of chicken contains nearly 21g of protein.
(2) Trace elements
Poultry meat is rich in phosphorus, selenium, magnesium and other trace elements, of which the body metabolism is inseparable from phosphorus, magnesium has a certain protective effect on cardiovascular disease, selenium can help improve the body's immunity. Each 100g of poultry meat contains about 12-19mg of magnesium, 120-160mg of phosphorus, and about 12-17mg of selenium.
(3) Unsaturated fatty acids
Poultry meat fat content is low, per 100g of poultry meat contains 10-20g of fat, of which the unsaturated fat content is high, accounting for about 70% of the fat ratio, this nutrient can reduce the risk of cardiovascular risk, is conducive to good health.
• Fish
In daily life, we are familiar with very little fish fat, the overall fat content is also much lower than red meat, poultry meat, accounting for only about 10%, and the fat of fish meat is basically unsaturated fatty acids, and the ratio of saturated fatty acids has reached 8:2, which is a veritable low-fat meat.
In fish, there is a polyunsaturated fatty acid DHA content is abundant, and the content of deep-sea fish is particularly high, compared with meat such as red meat, up to 3-7 times higher than other meats. DHA is a very powerful nutrient, it can not only promote the growth and development of the brain, improve intelligence, but also has a part of the therapeutic effect on Alzheimer's disease.
<h1 class="pgc-h-arrow-right" data-track="52" > third, people should eat more meat when they are old, especially fish</h1>
After Suffering from high blood lipids, Mr. Chen vowed to lower his high blood lipids in order to live in the world for a few more years, and made up his mind to fast in the future and become a vegetarian. At Mr. Chen's insistence, the effect is also there, and after a year or so, the blood lipid level returned to normal, which made Mr. Chen ecstatic and made him firm in his determination to carry out vegetarian food to the end.
The good times are not long, Mr. Chen walked for a long time after a dinner and did not return home, the family went out to find Mr. Chen lying on the side of the road, it was already a heavenly eternal separation, and later the doctor analyzed the cause of death because of heart attack,
After learning about Mr. Chen's situation, the doctor said that don't be mistaken by being smart, high blood lipids can not be solved by eating vegetarian alone, or have scientific and reasonable eating habits.
Many people are worried about the three high problems after getting old, and they will change from "carnivores" to "herbivores", but the elderly are likely to bring 3 major problems to the body by eating vegetarians.
First of all, meat is an important source of iron for the human body, and the "insulation" of meat will lead to insufficient intake of iron, and in severe cases, iron deficiency anemia will be triggered;
Secondly, eating vegetables and fruits alone can not solve the source of vitamin B12 intake, and not eating meat rich in vitamin B12 will lack vitamin B12, which will lead to problems such as dementia and arteriosclerosis;
In addition, meat as a high-quality protein source, not eating meat will also lead to protein intake can not keep up with their own consumption, especially after the elderly are old, their own muscles will gradually lose, protein loss to accelerate the rate of muscle decay, suffer from muscle decay, lack of muscle support and then cause the elderly to hunch over, arthritis and other incidence rates.
As mentioned above, what causes our blood lipid imbalance is due to the intake of too many saturated fatty acids, and this type of fat is mostly present in red meat, and poultry meat and fish meat are basically unsaturated fatty acids, in other words, in addition to the need to control red meat, poultry meat, fish meat these two kinds of meat can be eaten. Finally, we must pay attention to a balanced diet and arrange a scientific and reasonable diet. #Healthy Heat Plan ##谣零零计划 #
