Meat is one of the most important foods in our daily diet, and a considerable number of people in China especially like to eat meat, even to the point that they are not happy without meat;
Meat does provide us with a large number of nutrients needed by the body, but the intake of meat must be moderate and appropriate, for this reason, the professor of 301 Hospital told everyone: eat less meat, especially the elderly.
1. Why do we have to eat less meat?
Although meat is one of the most important sources of protein required by the human body, but the fat and red meat in meat contain high saturated fatty acids and cholesterol, if you consume too much, it will cause the deposits of fat and cholesterol to attach to the inner wall of blood vessels, and the blood vessels will be hardened, the lumen of the blood vessels will be narrowed and even the blood vessels will be blocked, and the blood will produce thrombosis because of poor flow and slow flow, resulting in embolism, which will lead to cardiovascular and cerebrovascular sclerosis, cerebral embolism, etc., and the thrombus will fall off if the rescue is not timely and easy to lead to paralysis and even death.
If you usually eat too much meat, the meat is acidic, which will acidify the blood, and the whole body will be acidic, which may damage various organs of the body, cause the deterioration of body functions, lead to the occurrence of various chronic diseases, and may be complicated by serious complications.
Studies have found that carcinogens may be produced in the process of further processing and production of red meat, especially the regular intake of processed meat products such as sausages and ham, which will increase the risk of colorectal cancer.
If you continue to consume too much meat, because meat has no dietary fiber, rich in fat and cholesterol, it is difficult to digest, during this period, excessive gastric acid secretion and repeated erosion, over time cause the stomach wall to become thinner and thinner, may first gastritis, repeated attacks lead to gastric ulcers, then gastric bleeding, serious and even gastric perforation.
If you eat too much meat, the excessive protein intake can not be fully absorbed by the body, which will lead to the occurrence of stones over time, causing stones in the gallbladder, ureters, kidneys and other parts, and the stones will progress, and the pain will be unbearable during the attack, and eventually surgery may be required to remove the stones, causing great damage to the body.
2. What are the benefits of meat to the human body?
(1) Meat supplements the nutrients needed by the body and can enhance people's immunity
In addition, meat also contains trace elements such as vitamin A, vitamin D, iron, zinc, etc., which can provide sufficient energy after ingestion, promote the metabolism of body substances, and enhance the ability to resist bacterial and viral invasion, thereby enhancing human immunity.
(2) Meat can increase the body's muscle mass
Part of the reason for the formation of muscle is related to the intake of protein, the protein ingested through eating meat can promote the synthesis of muscle, and at the same time, the trace elements such as creatine, calcium, and potassium contained in meat also promote muscle synthesis.
(c) Meat can help improve anemia
Meat is rich in iron, intake of meat can supplement a large amount of iron and zinc for the human body, and then promote the body's hematopoietic function, the condition of patients with iron deficiency anemia can be alleviated to a certain extent, and healthy people can also play a certain role in preventing the occurrence of anemia.
(4) Meat can provide DHA and other substances to the human body
According to research, meat has DHA to meet the needs of brain development, which can effectively promote brain development and improve the intelligence of the human body.
3. Who is more recommended to consume too much meat?
(1) People with cardiovascular diseases
Most of these people suffering from cardiovascular disease suffer from hyperlipidemia, hypertension and arteriosclerosis at the same time, if the cardiovascular arteriosclerosis, vascular lumen narrowing or arterial blockage, blood flow is not smooth, slowly produce thrombosis, resulting in embolism, fat is difficult to pass, then the cholesterol in the body will increase, if too much intake of meat, especially fatty meat, will aggravate the symptoms and progression of the disease and even unpredictable serious complications.
(2) People suffering from renal impairment and kidney disease
Excessive meat intake may increase the burden on the kidneys to a certain extent, especially meat with higher protein, which will aggravate the damage to kidney function and accelerate the progression of kidney disease.
(3) People with fatty liver
Fatty liver is caused by the accumulation of excessive fat in the body, and meat food, especially fatty meat, is the main source of fat, so after suffering from fatty liver, we must reduce the intake of meat, especially fatty meat, otherwise it will aggravate the progression of fatty liver and even affect liver function.
4. What kind of meat should middle-aged and elderly people eat?
(1) Meat containing high-quality protein
Middle-aged and elderly people should choose lean meat containing high-quality protein, such as chicken, fish, lean beef, etc. These meats not only contain a lot of high-quality protein, but also have a lower fat content, which is more conducive to the body's absorption. Fish, in particular, contains omega-3 fatty acids that are beneficial for cardiovascular health.
In addition, lean meat is also rich in minerals, B vitamins, iron and zinc, etc., which is conducive to the maintenance of bone health and the prevention of iron deficiency anemia in middle-aged and elderly people.
(2) Moderate intake of red meat
Red meat is rich in B vitamins, iron and zinc, which can enhance the immunity of middle-aged and elderly people and prevent the occurrence of anemia.
(3) Fish
Fish is rich in Omega-3 fatty acids, and the hospital professor said: Omega-3 fatty acids help reduce cholesterol levels in the body, thereby reducing the probability of cardiovascular diseases and other diseases, and it also has anti-inflammatory and antioxidant functions, so it is very suitable for middle-aged and elderly people.
Middle-aged and elderly people should consume more fish rich in Omega-3 fatty acids, such as salmon, sardines, salmon, etc., especially deep-sea fish rich in fat, which can better protect cardiovascular and cerebrovascular function and maintain cardiovascular health.
summary
Middle-aged and elderly people should consider a more comprehensive approach when choosing meat, not only to ensure the intake of sufficient amounts of high-quality protein, but also to avoid excessive fat and unhealthy meat intake, and to be clear about the meat suitable for intake;
In addition, the method of preparing the food is also very important, and it is recommended to choose steaming, stewing, boiling, etc., and avoid frying and grilling. Healthy diet is one of the key factors for longevity, and middle-aged and elderly people should choose and consume meat reasonably according to their physical conditions and nutritional needs.
