Take an adult who needs 2,000 kk of calories per day, for example, his daily intake of saturated fat should be controlled at about 22 grams;
for many people born in the 1970s, lard rice may be a delicacy of their childhood. With the improvement of people's living standards, fewer families use lard to cook, and their status in the food industry is declining. Because of its high saturated fat content, many experts do not even recommend that people eat lard.
, however, recently from the media video said that lard glycerin, slightly cold, non-toxic, can fight cancer, in addition to eating more lard is also good for the human cardiovascular, with health benefits ... Lard is a baby.
you say that lard is not only fragrant, but also a health care product? So should we eat lard?
oil is an essential nutrient and
Chinese history of eating lard is not short. Pigs were one of the first animals to be tamed by humans, and lard is popular because of its aroma. Therefore, pigs have been an important source Chinese protein and edible fats in many animals since ancient times.
since we have eaten lard for so long, does it mean that lard has a high nutritional value?
objectively speaking, lard does have certain nutritional value, and from the point of view of long human history, it also plays an important role in human reproduction.
, going back to the history of human evolution, we were all in a food-deprived state for quite some time, and we ate up and down. For those who were then, pork and lard were high-quality nutritional supplements. Closer to home, lard is also a very important dietary oil in times of shortage of supplies. Decades ago, people bought pork because fat pork was used to make oil.
, the body does need fat to synthesize important substances needed by the body, such as prosthetin, cholesterol, and some sex hormones; From a nutritional point of view, fat mainly has the following effects:
, lard can provide essential fatty acids. Essential fatty acids, which are unsaturated fatty acids, regulate the physiological function of the human body, but the body can not self-synthesize, can only be ingested from the diet.
, lard promotes fat-soluble vitamin absorption. Nutrients needed by the human body, such as vitamin A, vitamin D, vitamin E and vitamin K, are insoluble in water and soluble in oil. If the human body wants to digest and absorb them, it must take grease as the carrier.
, lard provides heat. Fat from the diet is an important source of heat for the human body.
, intake of the right amount of fat is also good for the human body, lard is no exception.
energy is too high, eating more is not conducive to health
although in human history, lard has contributed, but it is not a health care products.
main ingredients in lard are fat, and a large part of it is saturated fat, for human health has no special role, can not cure diseases, more unlikely to fight cancer.
addition, lard energy is too high, eating more is not conducive to health. You know, it's best to not exceed 25% of all the energy your body needs from fat every day. If fat supply accounts for more than 30%, it is prone to a variety of chronic diseases, the most common being cardiovascular disease. Numerous scientific studies have found that excessive intake of fat (especially saturated fat) and high energy intake increase the risk of cardiovascular disease.
an important reason for the increase in the incidence of cardiovascular disease in China is not that lard is eaten less, but that oil and other fats are consumed too much. Therefore, rumors that eating more lard is good for cardiovascular disease, is completely inverted.
to control the daily lard intake
Since lard can not eat more, then how much is appropriate to eat?
clear recommendations in the Dietary Guidelines for Chinese Residents: The average adult should consume no more than 10% of their total daily calories. In the case of an adult who needs 2,000 kK of calories per day, for example, his daily intake of saturated fat should be controlled at about 22 grams;
, that doesn't mean we can safely eat one or two lards a day. Because in addition to lard, most people will eat other foods, daily intake of meat, eggs, milk, nuts, biscuits, vegetable oil and other foods contain saturated fat, it is likely that lard is not "on the field", the daily intake of saturated fat is far more than the recommended amount of health. So, it's better to eat lard and take it easy.
