What you need to know about cholesterol - Is it really bad for you?

Overview

Despite the negativity attributed to cholesterol like stroke, heart attack and many cardiovascular diseases, it is a very important substance to the body. We can't survive without cholesterol. It is so important that our body naturally manufactures it in organs like the liver and the intestine. Cholesterol is a type of lipid (fat) needed to make key hormones like testosterone and estrogen, cell membranes, bile acids needed to digest and absorb fats, and vitamin D.

Cholesterol itself isn't a bad substance but can be bad for the body depending on its level in the bloodstream. 

Cholesterol doesn't mix well with liquids(blood) due to its fatty nature, so the body packages cholesterol in two forms:

•Low density lipoprotein (LDL)

•High density lipoprotein (HDL)

LDL is also known as bad cholesterol while HDL is good cholesterol. LDL create harmful cholesterol-filled plaques that grow inside the arteries and are responsible for health conditions such as angina (chest pain with exertion or stress), heart attacks and most types of stroke. LDL to HDL level ratio is a major indicator of heart disease.

What causes a rise in LDL?

In most cases, diet is the major cause. Consumption of foods rich in trans fats, saturated fats, and easily digested carbohydrates boost LDL. High LDL in the bloodstream can also be genetically traced or be as a result of medication.

Excessive LDL in the bloodstream creates harmful cholesterol-filled plaques that grow inside arteries. These plaques are responsible for angina (chest pain with exertion or stress), most strokes and heart attacks. According to WHO, 80% of deaths from cardiovascular diseases in 2005 occurred in low and middle-income countries and although, the global burden has since reduced low and middle-income countries still suffer the majority of the cases. Although, this is not surprising considering the lack of awareness on proper dieting and the poor living condition without the window for the choice of variety.

Regulation of cholesterol level

Essentially, the liver produces all the cholesterol we need but more cholesterol is obtained from animal products such as eggs, meat and dairy products. Food such as fried foods, fast food, Cheese, steak, organ meat, sardines, full-fat yoghurt, processed meats are high in cholesterol and therefore should not be consumed in excessive amount if it can't be avoided.

For a person with high cholesterol, making changes in diet can help reduce it to a healthy range. Exercise can also help to boost the level of protective HDL in the bloodstream.

The healthy technique to lower cholesterol level:

1.) Increase your physical activity.

2.) Lose weight.

3.) Consume more fibre containing food.

4.) Eat vegetables and fruits.

5.) Increase omega-3 consumption.

Conclusion:

Cholesterol is very essential for our body's development (hormones, cell membranes) but there's a thin line between its benefits and its hazards. Following the simple steps highlighted in this article would go a long way in helping you live a rich and healthy life.
