We have high-density lipoprotein cholesterol and low-density lipoprotein cholesterol in our bodies. In our popular words, high-density lipoprotein cholesterol is a "good thing" and low-density lipoprotein cholesterol is a "bad thing".
The higher the low-density lipoprotein cholesterol, the greater the probability of coronary heart disease, while the higher the high-density lipoprotein cholesterol, there is no serious problem. Generally speaking, the higher the HDL in the standard range, the better, which has a good protective effect on human body.
1. Inspection Introduction: HDL is mainly synthesized by the liver. It consists of apolipoprotein, phospholipid, cholesterol and a small amount of fatty acids.
2. Normal range: male < 40 years old 0.78 ~1.53 mmol/L (30 ~ 59 mg/dl);
Female < 40 years old 0.86 ~ 2.0 mmol/L (33 ~ 77 mg/dl).
3. Clinical significance: increased: generally considered to have no clinical significance, it can be seen in primary hypercholesterolemia (familial hypercholesterolemia), and it is found that many people in this group live longer. Those who receive estrogen, insulin or certain drugs (such as niacin, vitamin E, heparin, etc.). ) can also be increased.
Decrease: It is common in cerebrovascular diseases, coronary heart disease, hypertriglyceridemia and liver function damage, such as acute and chronic hepatitis, liver cirrhosis, liver cancer, diabetes, smoking and lack of exercise. Its decrease can be used as a risk index of coronary heart disease.
I'll reprint an article for you:
What is the clinical significance of the determination of 1 high density lipoprotein cholesterol?
High density lipoprotein cholesterol, abbreviated as HDL-C, reference range: male1.16-1.42 mmol/L; The decrease of female 1.29- 1.55 mmol/L, HDL-C is a precursor of clinical coronary heart disease, which can promote the development of atherosclerosis. Serum HDL-C level is negatively correlated with the incidence of coronary heart disease, and HDL-C or HDL-C/ total cholesterol ratio can better predict the risk of cardiovascular and cerebral atherosclerosis.
Decreased HDL-C is seen in the following diseases:
(1) Cerebrovascular atherosclerosis, coronary heart disease.
(2) Acute and chronic liver diseases, myocardial infarction, stress reactions such as surgery and injury, diabetes, hyperthyroidism or hypothyroidism, and chronic anemia.
2 High-density lipoprotein is low, what do you need to eat? What should we pay attention to in our daily life and diet?
As a nutritionist, I'll give you some suggestions: improve your living and eating habits, eat more foods with high protein and fiber, eat less or no foods with high calorie, high fat and high cholesterol, and usually eat more: carrot juice, orange juice, green tea, black tea and celery juice, and try to choose chicken and fish. If your conditions permit, you can better regulate the effect through nutrition!
How to improve your high-density lipoprotein cholesterol
"High density" is a popular abbreviation for "high density lipoprotein cholesterol". When evaluating atherosclerotic lesions such as coronary heart disease, it is necessary to comprehensively analyze various blood lipid readings, such as high density, low density (low density lipoprotein cholesterol), total cholesterol and triglycerides should not exceed the normal range.
According to the latest findings, the high density, nicknamed "good cholesterol" because of its work as a cholesterol scavenger, is most closely related to coronary heart disease. According to the current American standard, high-density reading below 1 (in mmol/L, that is, millimol/L, abbreviation) is an independent risk factor for coronary heart disease. That is to say, no matter how high your total cholesterol, low density and triglyceride are, as long as you raise your high density to a normal or optimal value, the risk of coronary heart disease will be greatly reduced. Every 0.025 increase in high density will reduce the incidence of coronary heart disease by 2% ~ 3%. It is ideal for men to be higher than 1. 16 and for women to be higher than 1.42. Followed by the proportion, the higher the proportion of high density in total cholesterol, the lower the risk of coronary heart disease. The average ratio of total cholesterol to high density in Americans is 4.5:1; Coronary heart disease was 5.5: 1. When the ratio reaches 3: 1, the risk of coronary heart disease is the lowest.
So, how to improve the high density? Losing weight is the first priority. For every 3 kg weight loss, the high density increased by 0.03; Every 10000 ~ 12500 steps/week, the high density increases by 0.026. Remember that the duration of exercise is more important than the intensity of exercise. Diet is second. High density can be reduced by 20% if the total heat is not carefully controlled. Different fats have different effects on blood lipids. For example, foods containing more monounsaturated fatty acids such as olive oil and nuts can increase high density without increasing total cholesterol. Foods with high polyunsaturated fatty acids, such as corn and soybean oil, have low density and high density. In addition, half an ounce to 1 ounce of wine per day can increase the high density by 5 ~ 10%. Finally, drugs, among which B vitamin nicotinic acid has the best effect, and others include statins and other lipid-lowering drugs.
Are you relieved to see this? Your high HDL cholesterol is a good thing, not a bad thing.
