The benefits of eating fat promote growth and development.
Fat contains cholesterol, which is an essential substance for brain, liver, heart and kidney, and is also the main raw material for many endocrine hormones in human body. High density lipoprotein in fat is an important source of cephalin and lecithin, which are indispensable for brain development. If children eat a low-fat diet for a long time, it will affect the growth and development of the brain and the whole body.
Promote the absorption and utilization of vitamins
Fat meat is rich in fat, which can promote the absorption and utilization of fat-soluble vitamins A, K, E and D. Long-term abstinence from fat can easily lead to the lack of fat-soluble vitamins, resulting in vision, blood coagulation and bone development disorders.
Replenish energy
Fat in fat meat is an important source of human calories, and fat produces twice as much calories as sugar. Fat meat is very important for athletes and manual workers, which can ensure people's energy and prevent fatigue.
Maintain normal body function
A normal human body needs to maintain 10%-20% fat to function normally. If the elderly do not have a certain amount of fat reserves, they will be skinny, and their immunity will decline, making it difficult to resist the invasion of diseases. If the body fat of women of childbearing age is lower than 17% of their body weight, their fertility will also be affected.
The disadvantage of eating fat is 1. Fat contains saturated fatty acids. Excessive intake of saturated fatty acids will lead to the increase of cholesterol, triglyceride and low density lipoprotein cholesterol (LDL-C) in blood, which will further lead to arterial stenosis and atherosclerosis and increase the risk of coronary heart disease.
2. Eating fat often will expose malnutrition, because fat is greasy and contains more amino acids, but vitamins and some carbohydrates are few, so if you often just eat fat, then malnutrition is very harmful to our growth.
3. For people who want to lose weight, it is not so easy to eat fat, because fat contains too many amino acids and fat, and eating fat will increase the calories we contain, which is naturally not smooth for weight loss, so if you want to lose weight, you'd better eat less.
Eating too much fat can cause various cardiovascular diseases such as hypertension or thrombosis. This is because there are too many payments in our blood, which pile up together, thus causing other coagulation diseases such as thrombosis.
How to eat fat? Saturated fatty acids can be reduced by 50% after long cooking. Therefore, fat meat should be stewed rather than fried, so as to foster strengths and avoid weaknesses.
Who shouldn't eat fat? People with obesity, atherosclerosis, hypertension, coronary heart disease and other diseases should eat less fat. However, people of standard weight and adolescents in development should eat some fat in moderation.
First of all, it can be said with certainty that any food is needed by the human body as long as it exists. The so-called "existence means need". The so-called good or bad refers to whether it will have a negative impact on health. In fact, there is no difference between good and bad food. The key lies in how we eat it.
Fat contains a lot of fat, and it is saturated fatty acid, which is also needed by human body. For example, it is one of the main components of cell membrane, and the human body is composed of countless cells; It is also a raw material for the synthesis of various hormones in the body. Without its normal physiological function, it will be affected.
However, if the intake of saturated fatty acids in the body is too high and cannot be fully utilized, it will be deposited in internal organs and subcutaneous tissues, causing obesity; It can also produce excessive cholesterol, and can also cause atherosclerosis and plaque formation, thus causing life-threatening cardiovascular and cerebrovascular diseases. In order to avoid these hazards, it is necessary to avoid excessive intake of saturated fatty acids.
The body needs neither too much nor too much. The best way is to control its intake. Dietary Guidelines for China Residents suggest that the daily intake of fat in a healthy diet should not exceed 25g, with vegetable fat as the main ingredient and animal fat as the supplement. Because the fat contained in plants is unsaturated fatty acid, it is beneficial to prevent the occurrence of atherosclerosis, but it does not mean that arterial fat should be completely replaced by plant fat.
Therefore, it is completely possible to eat a moderate amount of fat, of course, within five flowers. Take it twice a week 1-2, which can not only meet the needs of human body, but also satisfy the delicious enjoyment, and will not cause excessive consumption, thus avoiding the harm to human health.
I heard a joke before: one day, my friend told me that he solved the long-standing energy problem of mankind, "water turns into oil", because drinking water will make you fat. Yes, being fat means gaining weight. At first glance, drinking water fat makes everyone laugh, but when you think about it, drinking water alone can't maintain the needs of the human body, let alone turn it into fat.
In addition, when encountering this kind of problem, I want to go back with the phrase "toxicity first, not dosage". Seafood is a good thing, but uric acid is still high after eating too much. But when you turn your head, you should pay more attention. Anger hurts the liver.
I think that everything has its two sides, at least its advantages and disadvantages.
Disadvantages: Excessive fat intake may lead to increased blood lipid and pancreatic secretion, and if alcohol is added, pancreatitis may be induced. Eating too much fat directly converts other nutrients (mainly sugar) into fat storage (this is a basic skill evolved by human beings, and everyone is like this. If there are omissions, it will show its advantages when it is hungry and cold.
Benefits: Eating fat helps to absorb some fat-soluble nutrients, such as vitamins A and D; Proper fat helps to keep the stool unobstructed. "If you want to eat meat, you will be fat, and if you want to be thin, you will be thin." Eating fat and thin together will make you taste better and keep you in a good mood.
Therefore, moderate intake of fat is beneficial to health, while excessive intake may lead to metabolic imbalance.
Welcome everyone to discuss together. May everyone have a good appetite and good health.
(Answering laxatives)
Food has always been a topic. As a country with a history of 5,000 years, food culture has a long history, and meat in food occupies a very important position. For many food lovers, it is simply "no meat and no joy", and in this kind of meat, fat meat is more attractive.
Fat meat has its own attraction. There are hundreds of ways to make meat, but it seems that the fat meat in the finished product is more attractive than the lean meat. Pork belly alone will lose its soul without fat, and braised pork or roasted pork belly will lose a lot of color. A pot of pork belly, because it is fat, soft and attractive, makes diners eat three pieces of pork belly.
However, some people say that eating too much fat is harmful. As soon as this statement came out, I believe many food lovers were shocked. Losing the freedom of fat meat means losing the freedom of meat. So, is fat really harmful to the body? The truth is: eating fat occasionally will not affect your health, but if you eat fat for a long time, it will really hurt your health.
First, the harm of eating fat for a long time
First, it is easy to cause obesity. A very important reason for obesity is that too much fat is ingested, fat accumulates in the body, and lack of exercise is easy to gain weight. Fat, the fat content is close to 90%, indicating that the fat intake is high. If you eat fat for a long time and don't like sports, then it is likely that your waist will gradually disappear and you will gradually become a little fat man.
The second is to cause diseases such as hyperlipidemia and high cholesterol. Excessive accumulation of fat in the body will not only make people a little fat, but more seriously, these fats in fat will slowly accumulate in the body and accumulate on the wall of blood vessels, making blood more viscous, even hindering blood circulation, raising blood pressure and even inducing arteriosclerosis. People who like to eat fat for a long time are prone to hyperlipidemia and cholesterol increase because of too much fat in their bodies.
Judging from the above two points, you really can't eat too much fat. Although fat meat is delicious, you should control your appetite, eat fat meat in moderation, stretch your legs and exercise more. In fact, we should not only eat less fat, but also pay attention to the following points in order to enjoy the taste enjoyment brought by meat and eat meat healthily.
Second, three requirements for eating meat healthily.
First of all, whether you choose fat meat or lean meat, you'd better choose fresh meat, go home and cook by yourself, and try to eat less processed meat products, especially bacon.
Secondly, if you want to eat meat, you can choose fish and skinless chicken. The latter is also called white meat. White meat is low in fat and rich in nutrition. If you eat too much, you won't get fat so easily.
Finally, it's not just fat that should be eaten less. In fact, the amount of meat eaten every day is best controlled at 200 grams. In addition, you should eat more fruits and vegetables at ordinary times.
It can be seen that both fat meat and lean meat need to be controlled in intake, and they should not be eaten every day because they are delicious, not to mention delicious fat meat. If they are eaten every day, they will become dull. So fat meat is delicious, but health is more important.

This is not good, no matter who scores, it is good for very thin people to eat fat, but it is not suitable for obese people to eat fat, especially now most pork is raised in feed, and there are many bad substances left in fat, which is harmful to people's health.
What are the disadvantages of eating fat?
This problem was just discussed a few minutes ago. What effect does eating fat have on the body? What are the effects and disadvantages is basically a question.
Say a few simple words! Meat contains many essential elements for human body, so it is good for healthy people to eat meat.
For people with cardiovascular and cerebrovascular diseases, it is necessary to eat in moderation, especially fat. Because fat meat contains high fat, eating more will aggravate the condition. People with hypertension, hyperlipidemia and atherosclerosis have high blood viscosity. Eating too much high fat and cholesterol will aggravate the condition, which will seriously cause stroke and myocardial infarction. So, eat less fat. Eating lean meat is no problem.
In short, the advantages and disadvantages vary from person to person. Choose the best food according to your own situation! Achieve good health! For the purpose of happiness.
1, constipation
Actually, our digestive system is not suitable for eating meat. Eating meat often can lead to difficulty in excretion. Meat moves very slowly in the human gastrointestinal tract because of its low cellulose, so constipation has become a common problem for many people.
2. Cancer
People who eat fat regularly are more likely to get cancer. First, the butcher adds nitrates and preservatives in order not to spoil the meat, which is carcinogenic. Moreover, meat is often cooked, grilled and fried, which will produce a variety of carcinogens.
3. Hypertensive heart disease
Fat in animal meat, such as cholesterol, will not be completely decomposed in the human body after entering the human body, and these fats will adhere to the gastrointestinal wall and blood vessel wall. After a long time, the blood vessels will become narrower and narrower, and the amount of blood that can pass through will become less and less. Makes people suffer from high blood pressure and heart disease.
4. Calcium loss
Fat meat contains high protein, and people often eat meat. Protein in meat can lead to calcium deficiency. Can cause diseases such as osteoporosis.
There are many nutrients in fat meat, and the benefits brought by proper consumption are self-evident, such as promoting growth and development, promoting the absorption and utilization of vitamins, maintaining normal body functions and supplementing energy. However, eating too much fatty meat can not be underestimated, which will lead to the increase of blood cholesterol and triacylglycerol, promote arteriosclerosis and increase the risk of coronary heart disease.
Eating fat can promote growth and development, promote the absorption and utilization of vitamins, supplement energy, maintain normal body function, and so on. ...
However, fat contains saturated fatty acids. Excessive intake of saturated fatty acids will lead to the increase of cholesterol, triglyceride and low density lipoprotein cholesterol (LDL-C) in blood, which will further lead to arterial stenosis and atherosclerosis and increase the risk of coronary heart disease.
Therefore, I think we should eat less.
