Cholesterol is a waxy, fat-like substance that your body needs to build cells and make hormones. It’s found in all your cells, but most of it is made in your liver.
There are two main types of cholesterol:
- LDL cholesterol (low-density lipoprotein) is often called “bad” cholesterol because it can build up in your arteries and form plaque. Plaque can narrow your arteries and make it harder for blood to flow. This can increase your risk of heart disease and stroke.
- HDL cholesterol (high-density lipoprotein) is often called “good” cholesterol because it helps to remove LDL cholesterol from your arteries.
Your body needs some cholesterol, but too much LDL cholesterol can be harmful. You can lower your LDL cholesterol levels by eating a healthy diet, exercising regularly, and taking certain medications.
Cholesterol comes from two sources:
- Your liver makes all the cholesterol your body needs.
- You can also get cholesterol from the foods you eat.
Some foods are high in saturated and trans fats, which can raise your LDL cholesterol levels. These foods include:
- Fatty cuts of meat
- Full-fat dairy products
- Processed foods
- Fried foods
Other foods are high in soluble fiber, which can help to lower your LDL cholesterol levels. These foods include:
- Oats
- Beans
- Fruits
- Vegetables
If you have high cholesterol, your doctor may recommend that you get your cholesterol checked regularly. They may also prescribe medications to help lower your cholesterol levels.
Here are some tips for lowering your cholesterol levels:
- Eat a healthy diet that is low in saturated and trans fats and high in soluble fiber.
- Exercise regularly.
- Maintain a healthy weight.
- If you smoke, quit.
- Limit alcohol intake.
If you have any concerns about your cholesterol levels, talk to your doctor.
