Apolipoprotein B (ApoB): What Does This Value Say About Your Heart and Vascular Risk?

Cholesterol doesn’t tell the whole story about your cardiovascular risk. In this blog, we explain exactly what apolipoprotein B (ApoB) is, how it relates to your cholesterol levels, and when an elevated ApoB level is a reason to be extra vigilant. You’ll also learn which dietary and lifestyle factors influence your ApoB level.

More and more people are realizing that cholesterol alone isn’t enough to determine whether you actually have an increased risk of cardiovascular disease.

People often turn to statins right away, but it’s advisable to take a closer look at cholesterol to determine what might be causing any elevation.

Is ApoB a better predictor of the risk of cardiovascular disease?

Although cholesterol has long been considered a major risk factor for cardiovascular disease, it is increasingly recognized that measuring apolipoprotein B (ApoB) may be a better indicator of the risk of these conditions.

ApoB is a protein found on LDL cholesterol particles (also known as “bad” cholesterol) that circulate in the blood. LDL cholesterol can bind to the walls of blood vessels and accumulate there. This accumulation can lead to thickening and hardening of the blood vessels, restricting blood flow to the heart and other organs and increasing the risk of cardiovascular disease. ApoB is therefore a better indicator of the total number of LDL particles in the blood than measuring LDL cholesterol alone.

There are several reasons why measuring ApoB may be a better predictor of the risk of cardiovascular disease than measuring cholesterol, including:

• LDL cholesterol is just one of the many components of LDL particles. ApoB is a better indicator of the number of LDL particles than LDL cholesterol.
• Measuring ApoB can identify the presence of small, dense LDL particles, which are more atherogenic (i.e., have the ability to build up plaque in the blood vessels) than large LDL particles.
• In some people, LDL cholesterol may be relatively low, but there may still be a large number of LDL particles present, which indicates an increased risk of cardiovascular disease. Measuring apoB can help determine this risk more accurately.
• ApoB is less influenced by dietary factors, making it a more suitable constant measure for risk assessment.

Measuring ApoB is therefore a useful supplement to traditional risk factors for cardiovascular disease, such as cholesterol and blood pressure, and can help identify individuals at high risk for these conditions. However, it is important to emphasize that no single test can determine whether or not someone is at high risk for cardiovascular disease, and that a healthy lifestyle and regular monitoring remain essential for reducing these risks.

InsideTracker includes ApoB in its dashboard

InsideTracker is a company that offers personalized health recommendations based on data from blood tests and other biomarkers. The company has included ApoB in its test panel because of the important role it plays in determining the risk of cardiovascular disease.

Measuring ApoB levels can provide information about the total number of LDL cholesterol particles in the blood, which is an important indicator of the risk of cardiovascular disease. InsideTracker recognizes that measuring ApoB in combination with other markers such as cholesterol, triglycerides, and blood pressure can help determine the risk of cardiovascular disease on an individual level.

In addition, InsideTracker applies advanced algorithms and machine learning to the collected data to provide personalized recommendations for reducing the risk of cardiovascular disease and improving overall health. By including ApoB in the test panel, InsideTracker can improve the accuracy of its risk assessment and provide customers with better recommendations to improve their health and reduce their risk of cardiovascular disease.

InsideTracker has added ApoB to its “Blood Results Upload” plan because it provides more context for other lipid markers and enables a more comprehensive analysis of your heart health. Even if your biomarkers fall within a certain reference range, this does not always mean you are healthy. Research shows that optimal heart health is associated with ApoB levels below 90 mg/dL.

If your ApoB levels are higher than optimal, InsideTracker provides science-based recommendations to improve these levels, which in turn can help lower your LDL cholesterol levels.

What exactly does the ApoB test measure?

Apolipoprotein B (ApoB) is a protein that transports cholesterol on lipoproteins in the blood. There are different types of lipoproteins, such as high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL), all of which transport cholesterol. However, ApoB is the main structural component of VLDL, LDL, and lipoprotein A. These lipoproteins are potential culprits that can clog arteries and contribute to atherosclerosis.

Atherosclerosis is a condition in which plaques build up on the inner walls of arteries. If these plaques accumulate in the heart or brain, this can eventually lead to a heart attack or stroke. ApoB plays an important role in this process because it determines the amount of cholesterol that can be deposited in the artery wall. It can be viewed as a direct measure of the number of ApoB particles in the bloodstream, which can more accurately predict whether someone is at high risk for heart disease than a calculated measure such as LDL cholesterol, which is based on total cholesterol, HDL cholesterol, and triglycerides.

It is therefore important to know your ApoB level to assess your risk of cardiovascular disease. A high ApoB level may indicate that insufficient cholesterol is being removed from the blood, which often goes hand in hand with high LDL cholesterol levels. High levels of ApoB and LDL can lead to plaque buildup and narrowing of the arteries, which is a risk factor for heart disease.

Can you also get tested for ApoB at your family doctor’s office?

In the Netherlands, general practitioners generally do not offer a standard apolipoprotein B (ApoB) test as part of routine blood tests. As a rule, general practitioners will evaluate the traditional risk factors for cardiovascular disease, such as cholesterol, triglycerides, and blood pressure.

However, if a patient is at high risk for cardiovascular disease or if there are other reasons to believe that an ApoB test is necessary, the primary care physician will likely refer the patient to a specialist for the test.

There are several blood tests that can help assess the risk of cardiovascular disease in addition to cholesterol and apolipoprotein B. Some of these tests include:

1. C-reactive protein (CRP): This is a protein released during inflammation. A high CRP level may indicate an increased risk of cardiovascular disease.
2. Lipoprotein (a) [Lp(a)]: This is a type of lipoprotein that is structurally similar to LDL cholesterol. A high level of Lp(a) in the blood is an independent risk factor for cardiovascular disease.
3. Homocysteine: This is an amino acid that, when present in high concentrations in the blood, may indicate an increased risk of cardiovascular disease.
4. Glucose and Insulin: Elevated glucose and insulin levels may indicate insulin resistance, which can contribute to an increased risk of cardiovascular disease.
5. Triglycerides: These are fat molecules that circulate in the blood. High triglyceride levels may be a sign of an increased risk of cardiovascular disease.

Cholesterol is an essential molecule produced by every cell in our body that plays an important role in the formation of cell membranes and hormones.

Does what you eat directly affect your cholesterol level? It is possible to eat foods high in cholesterol without the cholesterol we consume through our diet remaining in our bodies.,

Although certain foods are rich in cholesterol, the cholesterol present in these foods is not directly absorbed into our bodies. Instead, the cholesterol we consume through our diet is esterified (bound to fatty acids) in the intestines before it is absorbed into the bloodstream. This esterified cholesterol is then excreted by the liver and cannot contribute to the buildup of cholesterol in the blood vessels. So eating foods that contain cholesterol does not necessarily mean that the cholesterol level in our blood will increase. Some foods can, however, stimulate cholesterol production in the liver, which can contribute to high blood cholesterol levels. LDL and HDL are simply lipoproteins that transport cholesterol and are not, in and of themselves, a cause of cardiovascular disease. It’s important to consider overall health and lifestyle factors such as exercise and diet, rather than focusing solely on cholesterol levels.

What should you do if your level is elevated?

If you want to optimize your ApoB level, there are several steps you can take. One way to lower your ApoB level is to eat fewer saturated fats and more fiber-rich foods such as oats and beans. Fiber, especially the soluble fiber found in oats and beans, can remove cholesterol from the body by binding to it and carrying it out. In addition, replacing saturated fats—such as those found in cheese, fatty meats, full-fat dairy, and palm and coconut oils—with unsaturated fats, such as olive oil or avocado oil, can help lower your ApoB levels and promote heart health.

To reduce the risk of cardiovascular disease, it is generally recommended to follow a diet rich in vegetables, fruits, whole grains, lean proteins (such as poultry, fish, legumes, and tofu) and healthy fats (such as nuts, seeds, and olive oil). Here are some specific foods you can include in your diet:

• Fatty fish, such as salmon and mackerel, which are rich in omega-3 fatty acids
• Whole-grain products, such as brown rice, whole-grain bread, and quinoa
• Fruits and vegetables, especially leafy greens and berries
• Nuts, seeds, and avocados, which are good sources of monounsaturated and polyunsaturated fats
• Legumes, such as chickpeas, lentils, and black beans
• Limit your intake of processed foods, refined carbohydrates, and saturated fats, such as deli meats, fried foods, fast food, and processed snacks.

In addition to diet, regular exercise, maintaining a healthy weight, quitting smoking, and reducing stress are also important for lowering the risk of cardiovascular disease.

If your ApoB level is too high, it’s important to take steps to lower it. Here are some possible steps you could take:

• Reduce your intake of saturated and trans fats: Foods such as red meat, full-fat dairy products, fried foods, and processed foods are high in saturated and trans fats. By reducing your intake of these foods and replacing them with healthier options such as whole grains, vegetables, fruits, legumes, nuts, and seeds, you can lower your ApoB levels.
• Increase your fiber intake: Fiber is important for lowering cholesterol and ApoB in the bloodstream. You can add high-fiber foods such as whole grains, fruits, vegetables, legumes, nuts, and seeds to your diet.
• Increase your intake of healthy fats: Unsaturated fats such as olive oil, avocados, nuts, and seeds can help lower your ApoB levels. So try to include more of these healthy fats in your diet.
• Increase your physical activity: Physical activity can help lower cholesterol and ApoB levels. Try to exercise regularly—for example, by walking, jogging, biking, swimming, or doing strength training.
• Consult your doctor: If your ApoB levels are too high, it’s important to consult your doctor. He or she can provide further advice and treatment options, such as prescribing medication.

When is a result considered normal?

The lab report from Bloedwaardentest, conducted by the certified hospital laboratory Medische Laboratorium Dr. Stein & Collegae, indicates that a value between 0.63 and 1.33 g/l is considered normal, but this is the medical reference range for people who are not ill.

InsideTracker indicates that the optimal level you can achieve by improving your lifestyle should be below 0.71 g/l

In the United States, ApoB is usually measured in milligrams per deciliter (mg/dL). In Europe and other parts of the world, however, the unit grams per liter (g/L) is typically used. To convert ApoB levels from mg/dL to g/L, divide the mg/dL value by 100, since 1 g/L equals 100 mg/dL.

So, for example, if a person’s ApoB level is 90 mg/dL, this would correspond to 0.9 g/L (90/100 = 0.9). If you have InsideTracker import our Dutch test results into your Dashboard, the unit will be converted automatically.

There is no single optimal blood level for ApoB that applies to everyone, because the ideal level depends on various individual factors such as age, gender, medical history, and so on. In general, however, it is believed that a lower ApoB level is better for heart health.

An ApoB level of less than 90 mg/dL (milligrams per deciliter) is generally considered optimal for the prevention of cardiovascular disease, while a level between 90 and 110 mg/dL is still considered reasonably safe. Higher ApoB levels may indicate an increased risk of cardiovascular disease and should be discussed with a doctor to determine a treatment plan.

Please note: ApoB is just one of many biomarkers that can be used to assess heart health. A comprehensive evaluation of heart health requires a thorough assessment of all risk factors, including blood pressure, BMI, smoking history, physical activity, and cholesterol levels.
