There is a proverb in China, "It is better to taste four or two birds than half a catty of beasts". "Four-legged" refers to domestic animals such as pigs, cows and sheep, also known as red meat. These meats are high in protein, but the fat is mainly saturated fatty acids. High fat and saturated fatty acids will affect human health, including susceptibility to cardiovascular and cerebrovascular diseases and some cancers. According to the World Health Organization's survey of 22 countries, the incidence and mortality of coronary heart disease are higher in areas with high fat intake. Among quadrupeds, pork has the lowest protein content and the highest fat content. Even for "lean meat", invisible fat accounts for 28%. More importantly, the fatty acids in meat are mostly saturated fatty acids, and the content of unsaturated fatty acids is very low. Saturated fatty acids tend to deposit cholesterol on the coronary artery wall. Therefore, some patients with cardiovascular diseases and hyperlipidemia who need to limit fatty acid intake should never think that eating "lean meat" is safe.
"Bipedal" refers to chickens, ducks, geese and other poultry, which are rich in unsaturated fatty acids and easy to digest and absorb. They are good meat food and are called white meat. French experts have analyzed the recipes of Gasco residents in the west of the country, and found that poultry fat is different from that of pigs, cows and sheep, and its composition is closer to olive oil. The fat intake of local residents is twice that of other parts of France and 50 times that of Americans, but the death rate of heart disease is only 1: 1250. The mystery is that most of the fat eaten by residents here comes from birds such as geese and ducks, which is not only harmless to the heart, but also has a protective effect. Of course, when eating white meat, the cooking method should be scientific, try to steam or stew, and use less frying. If you must use oil, try to use vegetable oil, and families with conditions can use olive oil.
The so-called "one leg" refers to fungus food such as fish and mushrooms, and also includes other aquatic products. Fish is high in protein and low in fat, short in fish fiber, delicate in meat quality, easy to digest and absorb, and has the highest absorption rate among animal foods. Mushrooms have a leg like an umbrella, which is low in calories. It is not only the source of protein, but also rich in various nutrients. Auricularia auricula and tremella fuciformis all belong to this kind of food. In addition to supplementing protein, it can also take human toxins out of the body, which is worth recommending. From the point of view of nutrition, it is better to eat poultry than pigs, cattle and mutton; It is better to eat fish and mushrooms than poultry. This is the saying that "eating four legs is better than eating two legs, and eating two legs is better than eating one leg".
Fish is one of the earliest foods for human beings. The protein content of fish is about 15% ~ 24%, and100g of fish can guarantee half of the daily protein for human body. Moreover, the absorption rate of these protein is very high, about 87% ~ 98% will be absorbed by the human body. Fish also provides vitamins a, d, e and so on. What the human body needs. Fish also contains a variety of fatty acids, and the fat content is less than that of livestock meat. Studies have found that eating more fish can not only increase cholesterol, but also reduce and prevent atherosclerosis and cardiovascular diseases. Experts believe that if you eat 280 grams of fish every week, you can reduce the incidence of heart disease and many other diseases, including breast cancer and migraine. The International Agency for Research on Cancer under the World Health Organization calls on everyone to eat more fish and less red meat.
Edible fungi are rich in eggs and contain many vitamins, which can enhance the immune function of human body against viral diseases. The protein absorption rate of mushrooms is 88%, the essential amino acids account for 38.8% of the total amino acids, and there are many rare amino acids. Mushrooms are rich in vitamins, trace elements, hexitol, pentitol, xylitol, octenol and so on. The interferon inducer and polysaccharide contained in it can enhance human immune function and inhibit the occurrence of tumors, so it is known as "anti-cancer health care treasure".
Fungi are nutritious and delicious. Protein is high in content and contains various vitamins, which can enhance human immunity to viral diseases. The protein absorption rate of mushrooms reached 88%. Its essential amino acids account for 38.8% of the total amino acids, and it also contains a variety of rare amino acids, as well as hexanol, xylitol, octenol and so on. Fungi contain interferon inducers and polysaccharides, which can enhance human immunity and inhibit the occurrence of tumors, so they are known as "anti-cancer health treasures".
Mushrooms and other fungi are low in calories and contain a variety of polysaccharides, all of which have anti-cancer effects. In vitro experiments show that more than 200 kinds of fungal foods have certain anti-tumor effects, especially fresh mushrooms.
Related studies have confirmed that Lentinus edodes can reduce blood cholesterol and have a good effect on hypertension and diabetes. In particular, Lentinus edodes contains lentinan, which can prevent and treat cancer, and its extract is used for anti-cancer treatment. Nutritionists praise Auricularia auricula as "vegetarian meat" because it contains protein, sugar, vitamins, fat, trace elements, phospholipids, sterols and adenosine. Remarkably, it is a blood-enriching food with high iron content. Adenosine, a water-soluble substance contained in Auricularia auricula, has the functions of inhibiting platelet aggregation, lowering serum triglyceride and β lipoprotein, lowering blood viscosity, reducing atherosclerosis and thrombosis.
In recent years, it has been found that the water-soluble substances in Auricularia auricula can inhibit platelet aggregation, reduce serum triglyceride and β lipoprotein, reduce blood viscosity, and reduce atherosclerosis and thrombosis. Therefore, eating Auricularia auricula15g every day, after blisters, can be eaten as a side dish twice in the morning and evening, which can prevent and treat diseases such as hyperlipidemia, arteriosclerosis and hypertension. Traditional Chinese medicine believes that auricularia auricula is flat in nature and enters the gastrointestinal tract, which has the functions of nourishing and benefiting the stomach, promoting blood circulation to stop bleeding and moistening dryness. In the past dynasties, doctors often used auricularia auricula10-30g for decoction or cooking to treat bloody dysentery, hemorrhoid bleeding, proctoptosis, menorrhagia, anemia, constipation and hypertension.
In fact, balanced nutrition is the key, which requires "eating" and storage, such as "four legs", "two legs" and "no legs" each 1/3. In processing and cooking, it is best to cook and stew, and try not to eat roasted, smoked and pickled meat products, so as to achieve the purpose of preventing diseases and strengthening the body.
