What Is HDL (Good) Cholesterol?

HDL cholesterol, also known as High Density Lipoprotein, is an essential fat-carrying particle composed of cholesterol, triglycerides and proteins. It is generally referred to as “good cholesterol” because it plays a crucial role in helping to protect your heart from potentially harmful diseases, such as cardiovascular events and stroke. Having a healthy level of HDL cholesterol is beneficial to your overall health and well-being.

Health Benefits of HDL Cholesterol

  • HDL cholesterol is thought to carry cholesterol away from the arteries and back to the liver, where it is removed from the body.
  • High levels of HDL cholesterol have been associated with healthy arteries and a reduced risk of stroke, heart attack, and cardiovascular events.
  • Having higher HDL cholesterol levels have also been linked to improved cognitive function and a lower risk of developing certain neurological disorders, such as Alzheimer’s.

Risks of Low HDL Cholesterol

Having low levels of HDL cholesterol can be concerning, as it raises your risk for potential health conditions. Listed below are some of the potential risks of having low HDL cholesterol:

  • Heart disease: Low levels of HDL cholesterol can raise your risk for heart disease, since HDL helps transport cholesterol out of the arteries and back to the liver for removal from the body.
  • Diabetes: There is evidence suggesting that low HDL cholesterol can increase the risk for certain types of diabetes.
  • Inflammation: Low HDL cholesterol has been linked to inflammation, which is an underlying cause of a variety of diseases and health conditions.
  • Stroke: Low levels of HDL cholesterol can raise your risk of having a stroke, as HDL helps protect your arteries from the build-up of fatty deposits.

Tips for Raising Your HDL Cholesterol

There are a few lifestyle changes you can make to help boost your HDL cholesterol levels. Some of these include:

  • Eating a Healthy Diet: Eating a diet high in healthy fats (such as olive oil, avocados, nuts, and seeds) and increasing your consumption of fiber can help raise your HDL cholesterol levels. Additionally, reducing your consumption of saturated and trans-fats and eating plenty of fresh fruits and vegetables can help maintain your HDL levels.
  • Exercising Regularly: Being physically active is one of the best ways to improve your HDL levels. Exercise raises your heart rate and helps your body burn fat, which can in turn help increase your HDL levels.
  • Maintaining a Healthy Weight: Excess weight is often associated with lower HDL cholesterol levels. Therefore, it is important to maintain a healthy weight in order to keep your HDL levels in check.
  • Limiting Alcohol Intake: Drinking excessive amounts of alcohol can lower your HDL cholesterol, so it is important to limit your intake to one drink per day for women and two drinks per day for men.


HDL cholesterol is an essential fat-carrying particle that plays a vital role in protecting your heart from potentially harmful diseases. It is important to keep your HDL cholesterol levels within a healthy range in order to maintain optimal health and reduce the risk of developing certain diseases. Luckily, there are a few lifestyle changes that can help boost your HDL levels, such as eating a healthy diet, exercising regularly, maintaining a healthy weight, and limiting your alcohol intake.
