Good vs Bad Cholesterol

We all hear about LDLs and HDLs when you go to the doctor’s office for cholesterol check-up but what do they really mean? For someone trying to maintain a normal range for these, see my earlier post on apple cider vinegar, I honestly feel you can monitor your health a little better if you know what you’re dealing with.

Let’s define LDL and HDL first. LDL (Low-Density Lipoprotein) and HDL (High-Density Lipoprotein) are two lipoproteins that play an important role in our health, but they have different functions. LDL, also known as the “bad” cholesterol, is a type of lipoprotein that carries cholesterol from the liver to other parts of the body. It is called “bad” cholesterol because high levels of LDL in the blood can increase the risk of heart disease and stroke. When there is too much LDL in the bloodstream, it can start to build up on the walls of the arteries, forming plaque. Over time, this plaque can narrow the arteries and restrict the flow of blood and oxygen, leading to the development of cardiovascular disease. While HDL, the “good” cholesterol, is a type of lipoprotein that carries cholesterol from other parts of the body back to the liver. It is called “good” cholesterol because high levels of HDL in the blood are associated with a reduced risk of heart disease. HDL acts as a scavenger, removing excess cholesterol from the bloodstream and reducing the risk of plaque buildup in the arteries.

For someone like me, what’s the levels I should be trying to maintain? The ideal level of LDL in the bloodstream is less than 100 mg/dL, while the ideal level of HDL is 60 mg/dL or higher. However, it’s important to remember that these are just general guidelines and individual values may vary based on personal health factors.

Eating a diet high in saturated and trans fats, as well as cholesterol, can raise the levels of LDL in the bloodstream–french fries “bad” unless homemade. On the other hand, eating a diet high in fiber, fruits, and vegetables–avocados “good”– can help to increase the levels of HDL in the bloodstream. Regular physical activity, quitting smoking, and maintaining a healthy weight can also help to improve the levels of LDL and HDL in the blood.

If you are concerned about your levels of LDL and HDL, talk to your doctor for personalized advice and guidance.

Stay well!
