Meat is an important source of protein and energy in our daily nutrition, and those who enjoy meat should certainly continue to eat it. However, it's also important to learn more about safety-related knowledge to minimize potential harm.
For example, the pathogen for mad cow disease is mainly found in the nervous tissues of cattle, such as the brain, spinal cord, and retina. We must be extra cautious when eating these parts of cattle. Furthermore, once a cow is infected with the mad cow virus, it is extremely difficult to eliminate, and even cooking the beef thoroughly is of no use. Therefore, never eat beef from epidemic areas or of unknown origin.
The avian influenza virus is not as severe. It spreads mainly through droplets, much like the common cold virus. As long as chicken or eggs are cooked for a longer period, the virus can be killed. Therefore, the most important thing when eating chicken is to remember to cook it for a longer time.

It is better to eat poultry than livestock, and better to eat fish than poultry.
Nutritionists suggest an important principle to follow when eating meat: it is better to eat poultry than livestock, and better to eat fish than poultry. Among meats, pork has the lowest protein content and the highest fat content. Even in "lean meat", the invisible hidden fat accounts for 28%. Therefore, patients with cardiovascular diseases or hyperlipidemia who need to limit their fatty acid intake should not think that eating "lean meat" is safe.
In addition, it is best to pair pork with legumes. Because bean products contain a large amount of lecithin, which can emulsify plasma, making cholesterol and fat particles smaller, suspending them in the plasma, preventing them from depositing on the blood vessel walls, and thus helping to prevent the formation of atherosclerotic plaques.
Poultry is a high-protein, low-fat food. The lysine content in chicken is 13% higher than in pork. The most nutritious way to eat chicken is to make a soup, which can also have therapeutic effects: it can boost spirits, eliminate fatigue, and treat depression; it can accelerate blood circulation in the nasopharynx, enhance bronchial secretions, help clear viruses that have invaded the respiratory tract, and alleviate cold symptoms. Moreover, goose and duck meat not only have a low total fat content, but their chemical structure is also different from pork, more similar to olive oil, consisting mainly of unsaturated fatty acids, which can protect the heart.
It is best not to eat fish skin and gills.
Fish is the best type of meat. Its flesh is tender and more easily digested and absorbed than livestock or poultry, making it especially suitable for children and the elderly. In addition, fish has a low fat content, with 80% of its fat being unsaturated fatty acids, which is greatly beneficial for preventing and treating cardiovascular diseases. The fat in fish also contains a fatty acid called DHA (docosahexaenoic acid), which is extremely important for activating brain nerve cells, improving brain function, and enhancing memory and judgment. Therefore, people often say that eating fish is good for the brain.
Mercury poisoning from eating deep-sea fish is mainly related to the increasing severity of ocean pollution. Therefore, when eating fish, there are a few parts we should pay special attention to and it's best not to eat them. For example, fish gills, skin, and fat are parts where pollutants tend to accumulate.
Do not exceed 200 grams per day.
Nutritionists often urge: currently, Chinese people eat too much meat. What are the harms of eating too much meat? Besides the high fat content in red meats such as pork, beef, and mutton, meat also contains purine bases. The metabolism of these substances in the body produces uric acid. A large accumulation of uric acid can damage the permeability of renal capillaries, causing diseases such as gout and poor bone development. The latest research also shows that excessive meat consumption can reduce the body's immunity, making it difficult to resist various diseases.
According to reasonable dietary standards, the average person needs 44-45 grams of animal protein per day. In addition to being obtained from meat, this protein can also be supplemented by milk, eggs, etc. Therefore, it is best to eat a meat dish once a day, preferably at lunch, with a portion size of about 200 grams. Then, supplementing with eggs and milk at breakfast or dinner can fully meet the body's daily need for animal protein.
