Beef, the strongest meat. Beef is the best choice for those who are weak and have mental decline. The amino acid composition of beef protein is closer to human needs than pork, and can improve the body's resistance to disease. It is especially suitable for growth, development, post operation, and post conditioning patients who supplement blood loss and repair tissue. But beef muscle fiber is rough and hard to digest, with high cholesterol and fat, so the elderly, children and people with weak digestion should not eat more.
Mutton, the most nourishing meat. Mutton is beneficial to the patients with asthma, tracheitis, lung disease and deficiency cold. It can also benefit the kidney and strengthen the Yang, nourish the deficiency and resist the cold, and strengthen the body. It is a nourishing and therapeutic treasure in winter. However, it should be noted that mutton, after all, is warm and not suitable for everyone. Yin deficiency, excessive fire, cough and phlegm, dyspepsia, arthritis, eczema and fever should be avoided.
Chicken, the least fat meat. The chicken here refers to the skinned chicken, because the fat of the chicken is almost all in the skin. Every 100 grams of skinned chicken contains 24 grams of protein, but only 0.7 grams of fat. Chicken has a good therapeutic effect on malnutrition, chills, fatigue, irregular menstruation, anemia and weakness.
Pork, the most iron supplement. The difference between fat and lean pork is large. The fat content in fat meat is high and the protein content is low. Eating more meat is easy to lead to diseases such as hyperlipidemia and obesity. Most of the protein is concentrated in lean meat, and the lean meat also contains hemoglobin, which can play the role of iron supplement and prevent anemia. Hemoglobin in meat is better absorbed than that in plants. Therefore, the effect of iron supplement in lean meat is better than that in vegetables.
Because the fiber tissue of pork is relatively soft and contains a lot of intramuscular fat, it is better to digest and absorb than beef. Traditional Chinese medicine believes that eating more lean meat in pork has the effect of nourishing yin and moistening dryness, and has certain therapeutic effect on diseases such as heat injury, dry cough and constipation.
Fish and shrimp, meat with the most trace elements. Fish and shrimp are rich in trace elements, including calcium, aluminum, iron, manganese, copper, cobalt, nickel, zinc, iodine, chlorine, sulfur, etc., which are necessary for human body. Although aquatic products are rich in nutrients, they should not be eaten more. Under the influence of marine pollution, aquatic products often contain toxins and harmful substances. Excessive consumption can easily lead to spleen and stomach damage and gastrointestinal diseases.
75 grams of meat a day, the size of a deck of cards
Experts said that we can also use milk and beans to replace the protein in meat, but B vitamins, essential fatty acids, zinc, iron and other minerals cannot be replaced by vegetables and fruits. 'so we don't need meat, we don't need too much. 'said Yu Kang.
Nutritionists say that the "diet balance pagoda" clearly points out that a person eats 75 grams of lean meat every day, a piece the size of a deck of playing cards. And vegetables, the best intake of about 500 grams a day. It's a pity that many people eat these two kinds of food in the opposite direction. '
Meat can be divided into red meat and white meat. Red meat refers to the meat that appears red before cooking. Pork, beef, mutton, rabbit and other meat of all mammals belong to this category. White meat refers to meat with delicate muscle fiber, low fat content and high unsaturated fatty acid content in fat, including birds (chicken, duck, goose, Turkey, etc.), fish, reptiles, amphibians, crustaceans (shrimp and crab, etc.) or bivalves (oysters, clams, etc.).
Manual workers are suitable for eating red meat, while mental workers are more likely to eat white meat; men have a large demand for red meat, while women have a small demand for red meat, so they can eat more white meat; the elderly's physical function is degraded, and eating more red meat is likely to lead to cardiovascular disease and Alzheimer's disease, so it's better to eat white meat; in order to meet the needs of physical development, children should eat both kinds of meat. Yu Kang reminded that if you have obesity, heart disease, hypertension and other chronic diseases, you'd better eat less meat and more legumes, such as soymilk, tofu, etc. if you want to eat especially, you must only eat lean meat to ensure the nutrition supply, and it will not aggravate chronic diseases. The cooking method of meat should follow the principle of "low fat". There are three eating methods, i.e. instant boiled meat, steamed meat and roast meat (the temperature is not too high), which will not add extra fat, but also remove the fat contained in some meat, which is the most healthy.
