Medical Myths: All About Cholesterol
From the Medical News Today website
Cholesterol is an essential component of animal cell membranes; as such, it is synthesized by all animal cells. Regardless of its bad name, cholesterol is essential for life.
However, when present in high levels in the blood, it increases the risk of cardiovascular disease.
Cholesterol, along with other substances, such as fat and calcium, builds up in plaques on the walls of arteries. Over time, this narrows the blood vessels and can lead to complications, including stroke and heart attack.
According to the Centers for Disease Control and Prevention (CDC), in 2015–2016, 12% of people aged 20 years or older in the United States had high cholesterol.
The World Health Organization (WHO) estimates that raised cholesterol levels are responsible for 2.6 million deaths each year.
