Listen to this article

Cholesterol is a waxy substance found in your blood’s fats (lipids). Although your body needs cholesterol to build healthy cells, too much cholesterol can lead to plaque buildup in your arteries (atherosclerosis). Plaque comprises fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries, decreasing blood flow and leading to a heart attack, chest pain, or stroke. High cholesterol can also increase your risk of other conditions, such as fatty deposits in your arteries (atheroma) and high blood pressure.

Where from it comes:

Cholesterol in your body comes from animal foods such as meat, poultry, and dairy products. These foods directly affect your liver which makes more cholesterol.

Types of cholesterol:

Cholesterol is of two types: LDL cholesterol and HDL cholesterol. LDL cholesterol is the “bad” cholesterol because it can build up in the arteries and form plaque. This can block blood and oxygen flow to the heart, leading to a heart attack. HDL cholesterol is the “good” cholesterol because it helps remove LDL cholesterol from the arteries.

Low cholesterol level:

A cholesterol level below 200 mg/dL is considered desirable for adults. However, a low cholesterol level in the body may have unexpected effects. For example, a low cholesterol level may be associated with an increased risk of death from any cause, according to a 2012 study. The study looked at data from over 12,000 adults and found that those with a cholesterol level below 160 mg/dL had a 33% higher risk of death than those with a cholesterol level of 160-199 mg/dL.

In addition, a low cholesterol level may also be associated with an increased risk of cancer. A 2013 study found that men with a cholesterol level below 140 mg/dL had a 24% higher risk of developing cancer than those with a cholesterol level of 140-159 mg/dL. So, while a low cholesterol level may be desirable, it is vital to be aware of the potential risks.
