Good Cholesterol Is A Complex Measure
While the cholesterol-carrying function of HDL is important, it’s not the only way HDL helps your body function. HDL also alters the chemical composition of LDL, preventing it from becoming oxidized, Harvard Medical School reported in 2019. That prevents damage to the arteries and lowers inflammation.
In general, having more HDL is often associated with a lower risk of heart disease. But too much HDL can also cause an inflammatory response in your immune cells, according to a 2016 study in the journal Cell Metabolism. That response can counter its usual anti-inflammatory properties. The upshot is that HDL’s function isn’t so clear-cut as being “good,” rather, its benefit to the body depends on a balance between its positive and negative effects.
To further complicate matters, a separate report from Harvard Medical School suggests that HDL might, in the end, be more of a “bystander” than an agent of good. It might simply be a “marker” of your cholesterol level, rather than having a significant influence on the body.
In fact, the American Heart Association no longer recommends a specific range for HDL and LDL cholesterol instead, they look at cholesterol as part of your entire heart health.
The takeaway, if you’re managing cholesterol, is not to put too much stake into one number. Healthy diet, exercise, and other lifestyle changes can boost your heart health regardless of the precise amount of “good” cholesterol in your body.
What Are Recommended Cholesterol Levels By Age
Lipids are the by-products of common fat we eat. Lipids are classified as triglycerides , diglycerides , and steroids. Cholesterol is a steroid helping in the formation of cell membranes and hormones. Further, this cholesterol is classified as Low-Density Lipoprotein or LDL, and High-Density Lipoprotein or HDL also called good cholesterol. VLDL is another type of cholesterol secreted by the liver into your bloodstream. VLDL stands for Very-Low Density Lipoprotein. Lipoproteins are formed partly by proteins and partly fat. All three types of lipoproteins vary in the proportion that is made of cholesterol, protein, and triglycerides. VLDL has more of triglycerides, LDL more of cholesterol, and HDL more of protein. That is the reason, LDL and VLDL are together known as the bad cholesterol, they both have a significant role in the formation of plaque. Now, plaque is a thick solid sticky mass made of fat, cholesterol, calcium, and other similar substances that get deposited in the arterial lumen interrupting the blood flow.
All in all, both types of bad cholesterol adversely affects your heart health either by getting deposited in the lumen of your arteries or under your skin and in the liver. If the lumen is completely choked, the organ may not get any blood supply. The plaque may burst and move to smaller arteries blocking them completely.
According to the American Heart Association, the following are the age-wise recommended cholesterol levels:
Hdl Vs Ldl Cholesterol
HDL cholesterol contains a higher proportion of protein and is made up of substances that dont lead to plaque buildup in your arteries. High-density cholesterol also carries LDL cholesterol away from the arteries back to the liver, where its broken down and eliminated from the body.
On the other hand, LDL cholesterol has a higher cholesterol and lower protein composition. When theres an excess of LDL cholesterol from consuming a diet high in calories and fat, excess LDL cholesterol seeps through artery walls and oxidizes .
When oxidation occurs, macrophages consume the oxidized LDL cholesterol in the artery wall and die, leading to inflammation in the artery walls. The body is then triggered to block the increasing macrophage by creating tissue in the artery walls called plaque, resulting in atherosclerosis.

What Complications Are Possible If You Dont Treat High Cholesterol Levels In Your Blood
The main reason to treat high cholesterol is to prevent or treat coronary heart disease , also called coronary artery disease or CAD. CHD happens when heart is not able to get enough oxygen-rich blood to function well and kills more people in the U.S. than any other cause of death. CHD usually refers to the large arteries, but there is also a condition called coronary microvascular disease that affects the small vessels and causes damage.
If Cholesterol Is Necessary Why Do We Have To Worry About How Much We Have
Having enough cholesterol to meet your needs is important. Having too much cholesterol can cause problems. If your cholesterol levels are high, the condition is called hypercholesterolemia. If your cholesterol levels are low, the condition is called hypocholesterolemia. It is not common to have cholesterol levels that are too low, but it can happen.

What Are Hdl And Ldl
HDL and LDL are two types of lipoproteins.They are a combination of fat and protein. The lipids need to be attached to the proteins so they can move through the blood. HDL and LDL have different purposes:
- HDL stands for high-density lipoproteins. It is sometimes called the “good” cholesterol because it carries cholesterol from other parts of your body back to your liver. Your liver then removes the cholesterol from your body.
- LDL stands for low-density lipoproteins. It is sometimes called the “bad” cholesterol because a high LDL level leads to a buildup of cholesterol in your arteries.
How Do You Prepare For A Cholesterol Test
In most cases, youll need to fast for nine to 12 hours before the test. Make sure you tell the person drawing your blood how long it has been since you ate or drank anything that wasnt water.
There are some cases when a cholesterol test is done without fasting. This is true for tests done at health screenings and may be true for people younger than 20 or for people who are unable to fast.
Some medical societies believe that fasting is not necessary to get a true picture of lipid levels in the blood, while other associations stand by the belief that fasting gives a better idea of a persons heart disease risk. You should be clear on whether or not you need to fast, and for how long, before you go for the blood test.

How Is High Cholesterol Treated
There are several ways to lower high blood cholesterol , including lifestyle changes or medication, or both. Your healthcare provider will work with you to determine which therapy is best for you.
Healthcare providers like to start with the least invasive treatments when possible, such as lifestyle changes. Youll be advised to:
- Avoid tobacco. If you do smoke, quit. Smoking is bad for you in many ways, and reducing your level of good cholesterol is one of them.
- Change the way you eat. Limit the number of trans fats and saturated fat. Eat heart-healthy foods like fruits, vegetables, poultry, fish and whole grains. Limit red meat, sugary products and dairy products made with whole milk.
- Get more exercise. Try to get about 150 minutes of physical activity every week, or about 30 minutes per day for most days of the week.
- Keep a healthy weight. If you need to lose weight, talk to your healthcare provider about safe ways to do this. Youll see results even before you reach your ideal weight. Losing even 10% of your body weight makes a difference in your cholesterol levels.
- Reduce the effect of negative emotions. Learn healthy ways to deal with anger, stress or other negative emotions.
- Control blood sugar and blood pressure. Make sure you follow your healthcare providers instructions for blood sugar levels, especially if you have diabetes, and for keeping blood pressure in the healthy range.

Can Bad Cholesterol Levels Be Too Low Can Good Cholesterol Levels Be Too High
It isnt often that people have bad cholesterol that is too low or good cholesterol that is too high. There are studies being done that suggest that extremes of any kind are not healthy for everyone.
Even though there is no clear-cut number about what LDL level is too low, levels under 40 mg/dL may be associated with certain health issues, including depression/anxiety, and hemorrhagic stroke.
However, there is data from clinical trials to support that there is no evidence of harm when LDLs remain < 40mg/dl on statin therapy.
In some cases, genetic conditions can cause you to have very low cholesterol levels. In other cases, nutritional problems, some cancers, hypothyroidism and certain infections can also cause low cholesterol levels. In any of these types of situations, the underlying issues need to be addressed.
In terms of having too much of a good thing, researchers are studying the effects of too much HDL, the good cholesterol. No conclusions have been reached, but there have been studies into the possible relationship between high HDL and cancer, and a greater risk of heart attack among the high risk. Excessively high HDL may be dysfunctional HDL and not protective.

Whats The Difference Between Hdl Ldl And Vldl
Cholesterol is a lipoprotein made of fat and protein. It is divided into three categories: high-density lipoprotein , low-density lipoprotein , and very low-density lipoprotein , and each impacts your body differently. HDL is considered good cholesterol as it helps move bad cholesterol from other parts of your body to your liver for removal. LDL is considered bad cholesterol because high levels can lead to the buildup of plaque in your arteries, said Chiadika. VLDL is considered bad cholesterol as well but it mainly carries triglycerides, the most common type of fat in your body. Excess levels can also contribute to health complications such as heart disease.
Cholesterol Levels For Children
By comparison, acceptable levels of total cholesterol and LDL cholesterol in children are different.
- An acceptable range of total cholesterol for a child is less than 170 mg/dL. Borderline high total cholesterol for a child ranges from 170 to 199 mg/dL. Any reading of total cholesterol over 200 in a child is too high.
- A childs LDL cholesterol levels should also be lower than an adults. The optimal range of LDL cholesterol for a child is less than 110 mg/dL. Borderline high is from 110 to 129 mg/dL while high is over 130 mg/dL.

Researchers are working on ways to eliminate plaque from coronary arteries. One method that has been proposed involves using combinations of medicines in healthy people aged 25 to 55 years. It is suggested that getting the levels of cholesterol down very low will allow arteries to clear up and heal up.
Several researchers believe that the way to reverse heart disease and prevent it in the first place is found in a whole-food, plant-based diet. Studies have been done that have shown that limiting nutrition to whole foods that are plant-based have been successful in reducing blood cholesterol and even, in some cases, lessening plaque buildup.

What Is Bad Cholesterol
Cholesterol moves in the body combined with proteins. This combination of cholesterol and proteins is called lipoproteins. The low-density lipoprotein or LDL cholesterol is called bad cholesterol. High levels of this cholesterol increase risk for heart diseases and stroke.
When you have high levels of LDL cholesterol in the body, the LDL cholesterol can accumulate on the walls of the blood vessels forming a plaque. The continuous cholesterol build-up or a plaque narrows the inside of the blood vessels with time. The narrowed blood vessel hampers the blood supply to the concerned organ. Thus, when the plaque is present in the heart, it can cause angina or a heart attack. Plaque build-up in the brain can cause a stroke.
Another type of cholesterol is HDL cholesterol. It is also called good cholesterol as it absorbs cholesterol and carries it back to the liver. The liver then removes the cholesterol from the body. HDL cholesterol, thus, can lower your risk for heart diseases and stroke.

High cholesterol can lead to heart disease, the number one cause of death in the United States. While some risk factors for cholesterol, such as age and heredity, are beyond your control, there are actions you can take to lower your LDL levels and reduce your risk, including:
- Eating a healthy diet. Reducing or avoiding foods high in saturated fat and cholesterol can help reduce the cholesterol levels in your blood.
- Losing weight. Being overweight can increase your cholesterol and risk for heart disease.
- Staying active. Regular exercise may help lower your LDL cholesterol levels and raise your HDL cholesterol levels. It may also help you lose weight.
Talk to your health care provider before making any major change in your diet or exercise routine.
Cholesterol: The Good The Bad And The Lipoprotein
Our bodies make and use cholesterol to aid in digestion, and to produce vitamin D and hormones. Cholesterol is a waxy substance that is found in many of the foods we eat, such as egg yolks, fatty meats, dairy products, and saturated oils. Too much cholesterol can cause plaque to build up on the walls of your arteries which can narrow blood flow. This may eventually lead to coronary artery disease or other health complications. Simbo Chiadika, MD, a cardiologist with UT Physicians, explains why.

What Are The Normal Cholesterol Levels For Men And Women
A cholesterol test generally determines 4 distinct numbers: Total cholesterol, LDL, HDL, and triglycerides. Cholesterol being fat, it is not soluble in water. So it cannot circulate freely in the blood. But, the fact is that nature has devised a way to make water-soluble cholesterol, and transport it through the blood. This is by lipoproteins. The LDL or Low-density lipoprotein and the HDL or high-density lipoprotein are the 2 fundamental cholesterol carriers but to make things simpler, they are considered as cholesterol types. In addition, the lipid panel appraises the triglycerides . They have an impact on health in the same manners as cholesterol. At last, the total cholesterol is integrated as well in the results. Apart from these 4 general lipid levels, your doctor may want to access your very low-density lipoprotein or VLDL that is considered bad when high.
Cholesterol Levels For Adults
- Total cholesterol levels less than 200 milligrams per deciliter are considered desirable for adults. A reading between 200 and 239 mg/dL is considered borderline high and a reading of 240 mg/dL and above is considered high.
- LDL cholesterol levels should be less than 100 mg/dL. Levels of 100 to 129 mg/dL are acceptable for people with no health issues but may be of more concern for those with heart disease or heart disease risk factors. A reading of 130 to 159 mg/dL is borderline high and 160 to 189 mg/dL is high. A reading of 190 mg/dL or higher is considered very high.
- HDL levels should be kept higher. A reading of less than 40 mg/dL is considered a major risk factor for heart disease. A reading from 41 mg/dL to 59 mg/dL is considered borderline low. The optimal reading for HDL levels is of 60 mg/dL or higher.

Eating The Right Foods For You
At ZOE, we run the largest nutritional study in the world, with over 15,000 participants so far. Our research has shown us that everyone responds differently to foods.
After you eat, your blood fat and blood sugar levels rise and then fall again. This is normal, but some foods can lead to more severe or continued rises and dips.
When repeated over time, this is associated with a greater risk of health conditions like coronary artery disease, stroke, and diabetes, which all have links to unhealthy cholesterol levels.
Also involved in these responses is your gut microbiome. This is the name for the community of trillions of different bacteria and other microorganisms that live in your gut.
ZOE scientists have identified 15 good and 15 bad gut bugs, linked to a higher or lower risk of many metabolic diseases. Some of the bad bugs are associated with having lower levels of good cholesterol.
With ZOEs at-home test, you can discover your personal blood fat and blood sugar responses to what you eat, as well as the unique makeup of your gut microbiome. The ZOE program provides personalized nutrition advice to help you find the best foods for your body and your long-term health.
