People with high blood cholesterol levels have a much higher risk of developing heart disease. High cholesterol levels are common with people over the age of 50, people with who are overweight, people with gastro-intestinal disorders and people with diabetes.
High blood cholesterol levels can be the result of either overproduction of the substance (due to liver dysfunctions) or the inability of the body to eliminate it. There are also many other external factors that contribute to cholesterol build up: inappropriate diet, sedentary lifestyle, smoking and alcohol abuse.
Although the body is able to produce the amount of cholesterol it needs for sustaining its normal activity, a high-cholesterol diet can significantly increase blood cholesterol levels. Foods of animal origin are rich in cholesterol and saturated fats that are very harmful to the organism when they are consumed in large amounts.
HOW TO REDUCE CHOLESTEROL LEVELS:
*You should replace meats and dairy products with vegetables, whole grain cereals and fruits in order to maintain normal cholesterol levels. Simple carbohydrates (sweets) enable cholesterol to build up inside the body and therefore should be avoided.
*Physical exercise is very important for keeping your blood cholesterol levels in check. Regular physical exercise improves blood circulation and helps in the elimination of excess cholesterol. Exercise frequently and you will be able to maintain normal cholesterol levels and lose extra weight.
*Smoking is considered to be a major factor of risk in heart disease. Smoking facilitates cholesterol to deposit inside arteries, where they can cause blockage. If you have high blood cholesterol levels and you are a smoker, stop smoking. Alcohol also contributes to the accumulation of cholesterol in the bloodstream.
Within normal limits, cholesterol is very important. The liver produces cholesterol in small amounts, as it is required in certain physiological processes. Without cholesterol, the body is unable to produce hormones (testosterone and estrogen), vitamin D (fortifies bone tissues) and bile (a very important substance used in digesting fat).
While in small quantities cholesterol is beneficial for the organism, in excess it can cause a lot of harm. Cholesterol is not soluble in blood and therefore it accumulates and deposits inside arteries, slowing down the normal blood circulation. High cholesterol levels considerably increase the risk of cardio-vascular diseases.
It is very important to know that there are several types of cholesterol. When you have your cholesterol levels checked, you are usually told the total cholesterol level. Total cholesterol level consists of high-density lipoprotein (HDL), low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL).
Low-density lipoprotein is known as “bad cholesterol” and this substance can be harmful to the human body when it accumulates in excess. Bad cholesterol (LDL) accumulates inside arteries and perturbs normal blood circulation. Good cholesterol (HDL) is benign to the organism, as it collects low-density lipoprotein from the bloodstream and brings it back to the liver.
By keeping a healthy diet and by exercising regularly, you will be able to raise your good cholesterol levels, while reducing bad cholesterol levels. By making improvements in your lifestyle, you will be able to maintain your total cholesterol levels in check.
