Where do the blood lipids come from? Why do some people eat meat every day and the blood lipids are not high?
Uncle Wang has always been mindful of his health, but the recent medical examination report showed dyslipidemia, which left him in confusion and pain. Every morning, he was always worried about the problem of blood lipids and didn't know how to solve it.
One day, Uncle Wang met his old friend Uncle Zhang in the community gym, a health expert who insists on exercising all year round. Uncle Wang told Uncle Zhang about his troubles: "Uncle Zhang, my recent physical examination report shows that my blood lipids are abnormal, and I have already controlled my diet and increased exercise, but my blood lipids have remained high, and I am really anxious." ”
Uncle Zhang smiled and patted Uncle Wang's shoulder: "Uncle Wang, don't worry too much, dyslipidemia is sometimes not completely caused by diet. Uncle Wang was stunned for a moment, and he didn't quite understand: "How is it possible? I have always paid attention to my diet and tried to eat less greasy food, but my blood lipids are still high." ”
Uncle Zhang patiently explained: "Yes, dyslipidemia is not only related to diet, but also related to the internal regulation of the body. Although some people don't pay much attention to their diet, their bodies are able to regulate the synthesis of endogenous blood lipids well, so even if they eat more meat, their blood lipids will not rise. ”
Uncle Wang's heart suddenly brightened up when he heard this, and he seemed to have found a glimmer of hope: "I see, I thought that as long as I controlled my diet, I could solve the problem of blood lipids, but I didn't expect that there was such a thing as endogenous blood lipids." ”
Understanding the source of blood lipids is the key to better control blood lipids
The sources of blood lipids can be divided into two categories: exogenous and endogenous.
Exogenous blood lipids mainly come from dietary intake, including fats and cholesterol in food, which enter the blood circulation after gastrointestinal digestion and absorption, forming chylomicrons.
Endogenous lipids, on the other hand, are mainly synthesized by the liver and produced along with liver metabolic processes, such as triglycerides and cholesterol. The intake and type of exogenous blood lipids directly affect the lipid level in the blood, so dietary structure is crucial for blood lipid regulation.
Endogenous blood lipids are affected by a variety of factors, such as metabolic regulation, genetic factors, etc., which need to be adjusted by considering individual conditions. Through a scientific and reasonable diet and a healthy lifestyle, blood lipid levels can be effectively controlled and cardiovascular health can be maintained.
Why do some people eat meat every day and their blood lipids are not high?
In daily life, we find that some people do not have high blood lipids despite having a rich diet and a lot of meat and fat, while others have high blood lipids despite having a light diet. Why is that?
The answer to this question lies in the source of blood lipids. Endogenous blood lipids are mainly synthesized by the liver, including triglycerides and low-density lipoprotein cholesterol. However, exogenous blood lipids ingested through food stay in the blood for a shorter period of time and have limited effects on vascular health.
Therefore, dyslipidemia is not caused by diet alone, but is more related to endogenous blood lipids synthesized by the liver.
One of the reasons why some people eat meat every day but do not have high blood lipids may be differences in individual metabolic capacity. Everyone's body has different metabolic mechanisms, and some people are able to metabolize the fat their body consumes more efficiently, thus keeping their blood lipids at normal levels.
In addition, dietary habits are also important factors that affect blood lipids. Despite eating a lot of meat, if you include enough fibrous foods such as vegetables, fruits, and whole grains in your diet, these foods can help promote digestion and absorption, slow down the absorption of fat, and thus reduce the risk of elevated blood lipids.
In addition, exercise is also one of the important factors affecting blood lipid levels. Moderate exercise can promote fat burning and metabolism, which helps maintain good blood lipid levels.
In addition, genetic factors and lifestyle may also affect blood lipid levels. Some people may be born with a strong metabolism and are less likely to cause dyslipidemia even if they consume a lot of meat. Others may have an unhealthy lifestyle, such as lack of exercise, smoking, excessive alcohol consumption, etc., resulting in elevated blood lipids.
Only by understanding the types of fat can we reduce lipids scientifically
Understanding the source of blood lipids can help us better develop a scientific and effective lipid reduction plan. In view of the situation of endogenous blood lipid elevation, we can scientifically lower lipids in the following ways:
- Control total caloric intake and avoid excessive energy intake;
- Reduce your intake of saturated and trans fats and choose healthy fats such as unsaturated fats;
- Increase your intake of fiber-rich foods to promote digestive health;
- Moderate aerobic exercise increases metabolic rate and promotes fat burning.
