Cholesterol is a type of fat (lipid) found in the bloodstream. It’s essential for various bodily functions, such as:
1. Building and maintaining cell membranes
2. Producing hormones (e.g., cortisol, aldosterone, and sex hormones)
3. Facilitating fat digestion and absorption
4. Supporting brain function and development
Cholesterol is carried in the blood by lipoproteins, which are classified into two main types:
1. Low-Density Lipoprotein (LDL): Often referred to as “bad” cholesterol, as high levels can lead to plaque buildup in arteries, increasing the risk of heart disease and stroke.
2. High-Density Lipoprotein (HDL): Considered “good” cholesterol, as it helps remove excess cholesterol from the bloodstream and transport it to the liver for excretion.
Cholesterol levels are measured in milligrams per deciliter (mg/dL) of blood. The American Heart Association recommends the following levels:
– Total Cholesterol: Less than 200 mg/dL
– LDL: Less than 100 mg/dL
– HDL: 60 mg/dL or higher
Maintaining healthy cholesterol levels through diet, exercise, and, if necessary, medication can help reduce the risk of cardiovascular disease.
Cholesterol is a waxy, fat-like substance found in your blood. It’s essential for building cells and producing certain hormones. However, high levels of cholesterol can lead to plaque buildup in arteries, increasing the risk of heart disease and stroke. There are different types, including LDL (low-density lipoprotein) and HDL (high-density lipoprotein), which have different effects on health.
