Take an adult who must have a fever of 2 calories a day as an example, and his daily intake of saturated fat should be adjusted to about 22 grams; If it is completely converted into lard, it is about 56 grams.
For many people born in the 197s, the bibimbap with lard may be a delicious food in their childhood. With the improvement of our living standards, the number of families cooking with lard is getting lower and lower, and its influence in the specialty food industry is also declining. Because of its high saturated fat content, many authoritative experts don't even recommend people to take lard.
However, recently, some videos uploaded by our media platform show that lard is sweet, cold and non-toxic and can prevent cancer. In addition, eating more lard is also beneficial to human cardiovascular and cerebrovascular diseases and has a healthy effect. Lard is really a commodity.
lard is not only fragrant, but also a health product? So should everyone eat lard?
oil is an indispensable nutrient element.
China people have a long history of eating lard. Pig is one of the first small animals accepted by people, and lard is loved by everyone because of its fragrance. Therefore, since ancient times, pigs have been the fundamental reason why many people in China ingest animal protein and take oil.
even if people eat lard for a long time, does it mean that lard has a high nutritional content?
Objectively speaking, lard does have certain nutrients. Judging from the long history of mankind, lard has also played a vital role in social reproduction.
first, back to the evolutionary history of mankind, for a long time, everyone was in a state of lack of ingredients, and there was no next meal after eating the last meal. For people at that time, pork and lard were excellent nutritional supplements. Recently, lard is also a key dietary oil in the era of material shortage. Decades ago, people bought raw pork and wanted proud meat, not lean pork, because fat pork could be used to cook oil.
Moreover, the human body really needs some fat to produce key chemicals needed by the human body, such as prostacyclin, carbohydrates, some estrogens, etc. In addition, oil can also maintain human skin and form cell tissue. From the pharmacological point of view, the key functions of oil are as follows:
First, lard can give essential fatty acids to human body. Essential fatty acids belong to unsaturated fatty acids, which can regulate the physiological function of human body, but human body can't produce them by itself, so it can only be ingested from diet.
Secondly, lard can promote the digestion and absorption of fat-soluble vitamins. Nutrients needed by human body, such as vitamin D, vitamin D, vitamin E and vitamin K1, are not easily soluble in water and oil. If the human body wants to digest and absorb, it needs oil as the medium.
finally, lard can generate heat. Fat intake in diet is the fundamental source of human fever. Therefore, proper intake of oil has advantages for human body, except lard. High kinetic energy, eating more is not conducive to physical and mental health. Although lard has experienced dedication in human history, it is not a health care product. The main component of lard is fat, and a large part of it is saturated fat. It has no special effect on human physical and mental health, and it is impossible to see a doctor, let alone prevent cancer.
In addition, the kinetic energy of lard is too high, so eating more lard is not conducive to physical and mental health. It should be understood that the kinetic energy of fat to the human body every day should not exceed 25% of all kinetic energy needed by the human body. If phosphagen's share of fat exceeds 3%, people will suffer from various chronic diseases, the most common of which are cardiovascular and cerebrovascular diseases. Many scientific studies have found that excessive intake of fat (especially saturated fat) and excessive intake of kinetic energy will increase the risk of thyroid diseases.
A key reason for the rising prevalence of cardiovascular and cerebrovascular diseases in China is not eating less lard, but eating too much oil and other fats. Therefore, it is rumored that eating more lard is beneficial to cardiovascular and cerebrovascular diseases, and it is completely unnecessary.
