LDL & HDL: Good & Bad Cholesterol | misjon.info
To help manage your risk of heart disease and stroke, it's important to know the difference between HDL and LDL cholesterol. Aim: To study co-relation between HbA1c &total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL) in diabetic patients with acute coronary. Physiol Res. ;54(2) Relations between particle size of HDL and LDL lipoproteins and cholesterol esterification rate. Dobiásová M(1), Urbanová Z.
As a matter of fact, it can, to some extent. A small particle carries less cholesterol than a large particle. Most people with this condition have high levels of insulin in their blood. The condition is common among individuals with abdominal obesity and the metabolic syndrome. If you are overweight, losing weight will probably lower your TG levels and so will reducing your intake of added sugar.
Studies have found that high intake of fructose leads to high TG. High-fructose corn syrup is a major source of fructose. Low-fat diets are usually not effective in lowering TG.
Adding omega-3 fatty acids, regular exercise and limiting alcohol may be helpful to reduce TG. Similar methods may be useful for raising HDL-C.
Losing weight, exercising and not smoking may help. The authors pointed out that fat-induced increase in TG following a meal is a postprandial phenomenon we all have high TG for a few hours following a fatty meal caused by chylomicrons is different from the carbohydrate-induced rise in TG later found to be caused by an elevation of VLDL.
These findings have been confirmed in several more recent studies. Despite this, low fat, high carbohydrate diets are still being recommended as a primary option to reduce the risk of heart disease. This suggests that solely selecting LDL-C as a target in cardiovascular prevention is an oversimplification, and may have led to wrong conclusions regarding the relationship between diet and heart disease.
What is the difference between HDL and LDL cholesterol?
If there is too much LDL cholesterol in the blood, it builds up in the walls of the blood vessels, causing them to narrow and stiffen. A buildup of LDL cholesterol reduces blood flow and can increase the risk of heart attack or stroke. HDL or good cholesterol can move LDL cholesterol from the blood to the liver, which breaks it down for disposal as waste. HDL cholesterol is referred to as good cholesterol because it reduces the level of cholesterol in the blood.
The Triglyceride/HDL Cholesterol Ratio
Higher HDL levels are linked to a reduced risk of heart attack and heart disease. What are the ideal ranges?
The guidelines for healthy cholesterol levels are as follows: Total cholesterol to HDL ratios The total cholesterol to HDL cholesterol ratio can help a person know if they are consuming enough good cholesterol and to limit sources of bad cholesterol. It can be measured by dividing the total cholesterol by the HDL level.
HDL (Good), LDL (Bad) Cholesterol and Triglycerides
Ideally, the ratio should be below 4. The lower this number is, the healthier a person's cholesterol levels are. Total cholesterol does fluctuate, so more than one blood test might be required for an accurate assessment.
Levels can change following a meal, so sometimes a blood test will be taken first thing in the morning before a person has breakfast. Studies suggest that the total cholesterol to HDL ratio is a better marker of the risk of heart disease than LDL cholesterol levels alone. This is measured by subtracting HDL cholesterol from the total cholesterol.
This method is considered to be more accurate by some doctors because it includes very low-density lipoprotein VLDL levels in the calculation.
