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.

LDL cholesterol tends to stick to the inner walls of the blood vessels it moves through. The coating reduces the blood flow through the affected vessels. This means poor circulation which translates to poor health. The coating may increase to an extent where the blood vessel is severely constricted. This condition is known as arteriosclerosis.

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.

Check the medium your food is cooked in. Stop using polyunsaturated vegetable oils because they change to trans-fats on heating, and trans-fats are harmful for health. Use olive oil instead, because it is a good cooking medium. Just this much is good enough to bring about a drastic reduction of LDL cholesterol.

Cigarette smoking is bad for health. It harms the body in more than just one way. Smoking increases the level of LDL cholesterol. So quit now and your LDL cholesterol will be gone tomorrow! The steps outlined in this article are very easy to implement. You will avoid the risk of heart disease if you follow them.

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!

Say no to saturated fats, both as food and as a cooking medium. Say no to cigarette smoking. Say no to stress. Say no to inactivity and a sedentary lifestyle. Say yes to regular exercise. If you do all this, you'll be saying: "Good riddance, LDL cholesterol! Hello, health!
