According to statistics, the incidence of dyslipidemia in Chinese adults is more than a quarter, that is, one in four people with potential hyperlipidemia.
In just 15 years, the prevalence of high cholesterol in mainland residents has soared nearly 1.9 times, from 4.9% to 14.4%.
This is a reminder that high cholesterol is harmful to much more than just the risk of cardiovascular disease, with studies showing that for every 1.03 mmol/L increase in plasma cholesterol, the relative risk of fatal ischemic stroke increases by 1%.

If the serum total cholesterol level increases by 1%, the risk of coronary heart disease will increase by 2~3%, in addition, high cholesterol may also increase the risk of osteoporosis, kidney disease, prostate cancer and other lesions.
Therefore, paying attention to the health of blood lipids and preventing high cholesterol is essential to maintain our quality of life and health.
01
What is the normal value of cholesterol?
Cholesterol is an important lipid that performs many important physiological functions in the human body. However, if cholesterol levels are too high or too low, it can have adverse health effects. Therefore, knowing the range of normal values for cholesterol is very important to maintain good health.
Normal ranges for cholesterol vary from laboratory to laboratory and standard, but in general, the normal range for total cholesterol (TC) is less than 200 mg/dl, for high-density lipoprotein cholesterol (HDL-C) is between 40 and 60 mg/dl, and for low-density lipoprotein cholesterol (LDL-C) is below 100 mg/dl.
If cholesterol levels exceed the normal range, it may lead to the development of diseases such as atherosclerosis, coronary heart disease, and stroke. Therefore, for patients with hypercholesterolemia, doctors usually recommend measures such as dietary control, increased exercise, and medication to lower cholesterol levels.
It is also important to note that there may also be differences in the range of normal cholesterol values for people of different ages, genders, and ethnicities. Therefore, when understanding your cholesterol levels, you should assess whether you need to take an intervention based on your specific situation.

The "cholesterol content ranking" was announced, and animal liver ranked seventh, and many people love to eat it at the top of the list
There are many types of foods that are high in cholesterol, and here are seven of them:
1. Eggs: Eggs are rich in nutrients, but egg yolks contain high cholesterol, so eating too much can lead to high cholesterol.
2. Fatty meat: Fatty meat contains a lot of saturated fatty acids and cholesterol, and long-term consumption of large amounts can easily lead to increased cholesterol.
3. Cheese: Cheese is a high-fat, high-cholesterol food, and eating too much can increase cholesterol intake.
4. Coconut oil: Coconut oil contains a lot of saturated fatty acids, which can easily lead to increased cholesterol when consumed for a long time.
5. Cakes and desserts: Cakes, desserts and other foods often contain a lot of sugar and trans fatty acids, which can promote the synthesis of cholesterol.
6. Fast food such as fried chicken and French fries: These foods are usually high in fats and trans fatty acids, and long-term consumption can easily lead to high cholesterol.
7. Animal offal: Animal offal has a high cholesterol content, especially in parts such as the liver and kidneys.

Does cholesterol be good and bad?
Is there really a "good" and "bad" relationship between cholesterol, a topic that has attracted much attention in the field of nutrition and medicine? Before we can explore this question, we first need to understand the basic properties of cholesterol. Cholesterol, as an important substance in the human body, not only participates in the composition of cell membranes, but also plays a key role in hormone synthesis. However, in recent years, a growing body of research has pointed out that high cholesterol levels may increase the risk of cardiovascular disease.
In order to better understand the "good" and "bad" aspects of cholesterol, we need to recognize the source of cholesterol in the body. Part of cholesterol is synthesized by the liver itself, while the other part comes from food. Among them, low-density lipoprotein cholesterol (LDL-C) is considered "bad" cholesterol because it tends to be deposited in blood vessels, forming atherosclerotic plaques, which in turn can lead to vascular narrowing and cardiovascular events. In contrast, high-density lipoprotein cholesterol (HDL-C) is considered "good" cholesterol because it can help reduce the risk of cardiovascular disease by bringing excess cholesterol back to the liver for metabolism and excretion.
So, how do you balance "good" and "bad" cholesterol levels? Moderate exercise, quitting smoking, limiting alcohol, and controlling weight can all help increase HDL-C levels in the body while lowering LDL-C levels. In addition, a proper diet is also crucial. Foods rich in soluble fiber such as oats, apples, beans, etc., can help reduce LDL-C levels, while foods rich in omega-3 fatty acids, such as deep-sea fish and nuts, can increase HDL-C levels.
In summary, there are "good" and "bad" types of cholesterol. In order to maintain good health, we should always pay attention to our cholesterol levels and adopt scientific lifestyle and dietary Xi to balance "good" and "bad" cholesterol. Only in this way can we truly prevent the occurrence of cardiovascular diseases and enjoy a healthy and happy life.
