Nowadays, more and more people begin to eat less meat or even reject meat in the name of health. There is also such a ridicule, saying that rural people do not understand the urban people: “We follow the people in the city to eat meat, but people in the city have begun to become vegetarian.†How does meat eat before nutrition? Has become a hot issue that many people care about.
Eat too much meat, hurt "heart" hurt "brain"
Scientific research has found that early humans only eat fruits and vegetables instead of meat. Until the post-glacial period, the fruits, nuts, and vegetables needed by humans were not enough. In order to survive, they began to eat meat from dead animals as a supplement. However, after the ice age, vegetarian foods were abundant and the habit of eating meat continued. In real life, we have a lot of "meat animals" around us, hamburgers, barbecues, roast duck, and braised pork - Dunton "no meat is not happy". According to 2002 national nutrition survey data, the daily animal food consumption of urban and rural residents in China is 248 grams and 126 grams respectively, while the Chinese Nutrition Society's standard is only 50-75 grams per day.
In fact, in ancient China, there was considerable controversy about eating meat. In "Lu's Spring and Autumn Period", it was pointed out that people who are good at keeping their health are "not cherishing the public's treasures," because "the taste of Zhen Zhong is filled by stomach and the stomach filling is very stuffy." Big bulging is not enough." “Zhenzhen†mainly refers to animal foods such as fish, flying birds, and beasts. The ancients thought that eating too much of this type of food would make the digestive function of the spleen and stomach dull, and it would also affect the smoothness of blood function. More and more experiments now show that eating too much meat is very harmful to the human body: In the United States, there are at least 1 million new heart disease patients each year, and nearly 600,000 people have lost their lives. According to a study by the American Heart Research Council, the majority of these patients with heart disease are eating too much meat and eating too little vegetables and exercise. In addition, eating more meat and high blood lipids, obesity and other metabolic diseases are also closely related. In a recent article in the British "Daily Mail", he said that even seemingly irrelevant diseases such as arthritis, gallstones, Alzheimer's disease, and osteoporosis are not related to eating meat. When humans become "carnivorous animals", not only do they cause damage to the body, but they also cause the dopamine in the human brain to thrive and the activity of acetylcholine to be abnormal, causing irritation, strong desires, and affecting intelligence." Senior Supervision, Suzhou Ringier Psychological Center Wang Guorong told reporters.
The most meat
Yang Li, professor of health sciences at the China Academy of Chinese Medical Sciences, said: “Excessive meat consumption is not good, but from a nutritional point of view, giving up meat is not a way of health. Dietary balance is what we advocate.†College of Food Science and Nutritional Engineering, China Agricultural University Associate Professor Li Xingmin said that in terms of agriculture, meat is generally divided into three categories: livestock, poultry, and aquatic products. Pigs, cattle, sheep, etc. are livestock; chickens, ducks, geese, etc. are poultry; fish, shrimp, shellfish, etc. are aquatic products. The three types of meat taste different nutrition, and the appropriate people are also different.
Beef: The strongest meat
For those who are physically weak and mentally degraded, eating beef is the most appropriate. The amino acid composition of beef protein is closer to the human body than pork, and can improve the resistance of the body. It is particularly suitable for people with growth and development, post-operative care, and post-mortem rehabilitation who supplement blood loss and repair tissue. However, beef muscle fibers are rough and indigestible, and have high cholesterol and fat. Therefore, the elderly, infants, and people with poor digestion should not eat more.
Lamb: the most nutritious meat
Lamb helps Yuanyang, supplements blood, and treats lung deficiency. It is beneficial to people with asthma, bronchitis, lung disease, and deficient cold. It can also benefit the kidney, strengthen the body, resist cold, and strengthen the body. It is a nourishing food treasure of the winter season. However, it should be noted that after all, mutton tends to be warm, not everyone. Yin Huo-wang, cough, indigestion, arthritis, eczema and fever should not eat.
Pork: The most iron-filled meat
Pork fat lean is different, fat is high in fat, protein content is low, eat more easily lead to high blood fat and obesity and other diseases; most of the protein is concentrated in lean meat, and lean meat also contains hemoglobin, can play iron The role can prevent anemia. Hemoglobin in meat is better absorbed than in plants, so eating lean meat is better than eating vegetables.
Because pork's fibrous tissue is soft and contains a lot of intermuscular fat, it is better digested and absorbed than beef. Chinese medicine believes that eating lean meat in pork has the effect of nourishing yin and moistening, and has a certain therapeutic effect on diseases such as fever, dryness, cough and constipation.
Chicken: Fat with the least fat
The chicken mentioned here refers to the peeled chicken because chicken fat is almost all in the skin of the chicken. Every 100 grams of peeled chicken contains 24 grams of protein but only 0.7 grams of fat. Chicken has a good therapeutic effect on malnutrition, chills, cold fatigue, fatigue, irregular menstruation, anemia, and weakness.
Fish and shrimp: meat with the most trace elements
Fish and shrimp are extremely rich in trace elements, containing calcium, aluminum, iron, manganese, copper, cobalt, nickel, zinc, iodine, chlorine, sulfur, etc., are all necessary for human body. Although aquatic products are rich in nutrients, they should not be eaten. Affected by marine pollution, aquatic products often contain toxins and harmful substances. Excessive consumption can easily lead to spleen and stomach damage and cause gastrointestinal diseases.
75 grams of meat per day, one deck size
Yu Kang, deputy director of the Clinical Nutrition Department of Peking Union Medical College Hospital and Song Xinjun, deputy director of the Department of Nutrition of Beijing Chaoyang Hospital, said that the protein in the meat can be replaced with milk and beans, but B vitamins, essential fatty acids, and zinc, iron and other minerals Substances cannot be replaced with fruits and vegetables. "So we don't need meat, but we don't need too much meat." Yu Kang said.
The Secretary-General of the China Nutrition Society, Mou Fengying, stated that the “Baby Balance Pagoda†clearly stated that one person would consume 75 grams of lean meat per day, which is the size of a pair of playing cards. And vegetables, the best intake of about 500 grams a day. "It is a pity that many people now eat these two things in reverse."
Yang Li said that meat is divided into red meat and white meat. Red meat refers to the red meat that is present before cooking. Pork, beef, mutton, rabbit, and all other mammalian meats belong to this category. White meat refers to meat with fine fiber, low fat content, and high content of unsaturated fatty acids in fat, including birds (chicken, duck, goose, turkey, etc.), fish, reptiles, amphibians, crustaceans. Animals (shrimp crabs, etc.) or bivalves (oysters, clams, etc.).
Physical workers are suitable for red meat, while mental workers eat more white meat; men have a greater demand for red meat, women have less demand for red meat, and can eat more white meat; the elderly have deteriorating body functions, and eating red meat can easily lead to cardiovascular disease. Disease and senile dementia are still good for white meat; children need to eat both types of meat in order to meet the needs of physical development. Yu Kang reminded that if you suffer from chronic diseases such as obesity, heart disease, and high blood pressure, it is best to eat less meat and eat more beans, such as soy milk and tofu. If you want to eat especially, you must eat only lean meat to ensure nutrient supply. It will not increase chronic diseases. The cooking method of meat should follow the principle of “low-fat†in a unified way. The three ways of eating meat, steamed meat, and grilled meat (not too high in temperature) will not increase extra fat, but also remove some of the meat itself. Fat, the healthiest.
