What Is Cholesterol In the Body?

What is cholesterol and how can we describe it?

Cholesterol is often described as a waxy, fat-like substance that circulates in the body and can contribute to health issues, particularly affecting the heart and arteries. However, many people are unaware that it is divided into different types, some are harmful and others beneficial. 

The beneficial types play vital roles in the body, such as boosting energy and aiding cell construction. You may have encountered questions like: What is LDL? What is HDL? And how do they differ? In this article, we’ll explore these questions and more.

Certain foods can raise bad cholesterol, such as those containing hydrogenated oils and other unhealthy ingredients. On the other hand, there are healthy foods that help the body eliminate harmful substances and maintain overall balance. It travels through the bloodstream in three main forms:

An LDL test can measure the level of low-density lipoprotein in the body and is considered essential for monitoring health. LDL is often referred to as "bad" because it transports it from the liver to the cells. High LDL can cause plaque buildup in the arteries, raising the risk of heart disease and stroke.

An HDL test measures "good" cholesterol, which helps remove excess it from the bloodstream by transporting it back to the liver for elimination. Higher HDL levels are linked to a lower risk of heart disease.

This type is called “bad” because it also contributes to plaque buildup in your arteries. However, VLDL and LDL are different; VLDL primarily carries triglycerides and LDL primarily carries cholesterol. Comprehensive tests can be done, including an analysis, to distinguish between harmful and beneficial levels in your body.

Cholesterol itself is not inherently harmful; it is vital for many essential bodily functions. However, an imbalance, such as high levels of harmful cholesterol or low levels of good cholesterol, can cause risks. 

This imbalance may lead to atherosclerosis, a condition where arteries become narrow and hardened due to plaque buildup. Atherosclerosis increases the risk of heart attacks, strokes, and other cardiovascular issues. Foods like processed meat, sugars, fried and fast foods, can cause harms to your overall health.

After we answered what is cholesterol in the body, there are several factors that affect its percentage in the body, some of which are considered good and others are considered harmful, such as:

Your diet plays a key role in determining your cholesterol. Consuming unhealthy foods can raise the harmful in your body, while eating healthy, natural foods helps maintain a healthy and balanced levels.

In some people, the levels may increase due to genetic factors, a condition called familial hypercholesterolemia. If you have this condition, it’s important to undergo regular tests and adopt a healthy, balanced lifestyle to help manage it.

Regular physical activity can boost good cholesterol and lower harmful ones. Aim to exercise at least three days a week with activities like Pilates, cardio, or other workouts. Combined with weight loss, exercise helps reduce body fat and control harmful levels.
