HDL cholesterol (high-density lipoprotein) is the supposed excellent cholesterol in the blood serum. It is responsible for carrying excess cholesterol away from the body cells and arteries back to the liver. The liver integrates cholesterol with lipoproteins for use in different physiological body functions and building of cells. A lipoprotein is a consolidated unit of lipid, that is, fat on the within surrounded by protein on the outside.
Since cholesterol is water-insoluble, the blood can not carry it unless it is become a water-soluble type. That is where water-soluble lipoproteins get in the scene. They integrate with cholesterol to form water-soluble systems that can move with the blood stream.
These lipoproteins are mostly of 2 types: low-density (20-25 % proteins) lipoproteins, LDL and high-density (40-55 % protein) lipoproteins, HDL. Medical experts describe the cholesterol transported by HDL as HDL cholesterol.
So, when clinical experts talk of HDL cholesterol, they mean HDL-bound cholesterol. Medically talking there is no such thing as "good cholesterol" or "bad cholesterol". Cholesterol is simply cholesterol, a sterol lipid having the chemical formula C27H45OH. In fact, HDL and LDL are not cholesterol at all. They are just lipoprotein vehicles for bring and moving cholesterol with blood.
Many people commonly call HDL excellent cholesterol since it travels from the arteries and body cells back to the liver for recycling or removal. This avoids a build-up of plaque (a hard fatty deposit) on the inner walls of significant arteries providing blood to the organs. This decreases obstructing of the arteries and the danger of cardiovascular disease, paralysis, and high blood pressure.
Experts have just recently discovered that low HDL cholesterol level in blood is an independent risk factor for these cardiovascular and crebrovascular diseases. HDL levels below 40 mg/dL for guys and below 50 mg/dL for ladies are thought about low. This is separate from the total cholesterol and LDL levels. This suggests that even with a normal overall cholesterol count and a safe LDL level, people with low HDL cholesterol levels are at an increased threat of heart disease.
So the emphasis needs to not just be on lowering the overall cholesterol and LDL levels, however also raising the HDL cholesterol level. Study has actually revealed that a drop of just 1 mg/dL in the HDL cholesterol level can reduce a person's risk of suffering a deadly cardiovascular disease by 3 %.
But exactly how does one raise the HDL cholesterol level while keeping the complete cholesterol and LDL levels low? Preferably, an HDL more than 50 mg/dL for guys and 60 mg/dL for ladies is considered heart-protective. Many people, nevertheless, can push the HDL cholesterol levels up by making some way of life and diet modifications.
Raising HDL Cholesterol
To raise your HDL cholesterol, use up an aerobic activity like walking, cycling, swimming or dancing for 30-40 minutes 5 times a week. Quitting smoking cigarettes, losing excess weight and consuming foods rich in nutritional soluble fiber, omega-3 fatty acids and anti-oxidants likewise raises the HDL cholesterol levels.
An additional way of living change that is effective in raising HDL cholesterol is saying no to saturated and trans fats (red meats, egg yolk, butter, whole-cream dairy products, industrial bakeshop items, deep-fried foods, and so on). Instead choose a diet based upon polyunsaturated and monounsaturated vegetable oils, whole grains, grains, nuts like almonds and walnuts, flax seeds, beans, legumes, lentils, fruits and vegetables.
The only medicines understood to raise HDL cholesterol efficiently are niacin (vitamin B3) and a training of substances called fibrates.
