The LDL Cholesterol Connection With Heart Disease

By Ned Dagostino

Cholesterol is a vital element for our health and well-being. There are two basic types of cholesterol: HDL cholesterol is good for our health, LDL cholesterol is bad for our health.

LDL stands for low density lipoprotein, with the 'lipo' prefix indicating 'fatty'. Similarly HDL stands for high density lipoprotein. The liver produces HDL cholesterol. This HDL cholesterol is used to repair damaged tissue and even to replace the dead tissue. The byproduct of this repairative work is LDL cholesterol. The LDL cholesterol is flushed out of the system by our circulatory and excretory systems. The body has regulatory mechanisms to ensure the proper balance of HDL and LDL cholesterols. However, at times, the level of LDL cholesterol exceeds the normal range and we end up with high LDL cholesterol levels in the blood. This is bad for our health.

Excessive LDL cholesterol sticks to the inner walls of the blood vessel and forms a plaque which reduces the blood flow. This condition is called arteriosclerosis, which is the harbinger of critical heart diseases.

If this situation carries on for a long time, the blood flow is obstructed and the blood pressure increases leading to overloading of the heart. The plaque can accumulate to such an extent that it completely blocks the blood vessel, or it may get dislodged from one location and lodge itself in a narrower blood vessel, like a capillary, creating a blockage there. Blood supply is choked off at that point, and leads to blood starvation in the region beyond the blockage. If this blood starvation occurs in a critical area of the body, as for example in the brain, then we get a crisis. The affected area of the brain shuts down and this leads to a 'stroke' wherein the body experiences paralysis in those areas controlled by the area of the brain which has shut down. If the blood vessels of the heart are affected by blockage, then we get a critical situation known as a heart attack. All this is due to an excess of LDL cholesterol in the blood.

There is just one thing we can do to guard against heart disease caused by excessive LDL cholesterol: assist the body in regulating the blood cholesterol level. The most effective way is by controlling what we eat. Medical researchers tell us that the most common reason for excessive LDL cholesterol is our over-indulgence in saturated fats, both directly and indirectly. We can have fatty foods which are good for health, like the omega-3 group of fats. The omega-3 fats actually work to reduce the LDL cholesterol in the blood, so we should have a lot of tuna and salmon because they are rich sources of omega-3 fats. Studies show that drinking a lot of water helps to increase the blood circulation which goes a long way in reducing LDL cholesterol.

Stop using heavy cooking oil to cook food in. Switch to virgin olive oil which is highly recommended as a healthy cooking medium. Changing your cooking oil is a very effective way to reduce the risk of heart disease.

Quit smoking. We all know that smoking is bad for the lungs and is also a carcinogenic activity. What most of us don't know is that smoking aggravates the high LDL cholesterol condition. The LDL cholesterol will drop almost immediately from the time you stop smoking, and it will drop further if you do as mentioned in this article.

High stress environments lead to high levels of LDL cholesterol in the body almost immediately. Learn to deal with stress. When your slave driver calls you up, prepare yourself to remain calm! The mind is the best tranquilizer for you! If possible seek a change of environment for the sake of your health. Health is wealth, and that's for sure!

If you (or a near one) suffer from a high LDL cholesterol level, don't get all worried up about it. That will be counter-productive. You should be positive instead. You can do a lot to bring the LDL cholesterol levels down to normal. Start having a good, healthy and balanced diet. Increase the amount of your activity. Start exercising, and continue to do so regularly. Stop smoking altogether. Not only will your bad cholesterol level get itself back to where it belongs, but your exposure to heart attack and stroke will disappear as well. Don't worry, be happy!
