What About A Low
Substantial evidence now shows that a low-fat diet often reduces rather than increases HDL levels. This result is not specifically caused by not enough fat, but rather, is caused by consuming too many carbohydrates. The American Heart Association and the American College of Cardiology have quietly stopped recommending low-fat diets for heart disease prevention. Indeed, it is low-carb diets and not low-fat diets which are associated with higher HDL levels.
How To Lower Ldl Cholesterol
Lifestyle and diet changes are the main ways to prevent or lower high LDL. A trial of eating a low-fat diet, regular aerobic activity, maintaining a healthy weight, and smaller waist circumference is an appropriate first step. It is best to set a timeline to achieve your goals with your doctor. In some cases, if those lifestyle changes are not enough, your physician may suggest a cholesterol lowering medication, such as a statin. If you are considering over-the-counter herbal or ayurvedic medications for cholesterol, please discuss those with your physician first as well.
Rarely, very high LDL is genetic and passed down in families. This is called familial hypercholesterolemia and is caused by a genetic mutation that decreases the livers ability to clear excess cholesterol. This condition can lead to very high LDL levels, and heart attack or stroke at a young age in multiple generations. Those individuals may require special medical treatment for prevention and treatment of atherosclerotic cardiovascular disease.
Remember, knowledge is the first step. If you dont know your cholesterol levels, get tested. That will give you and your physician a starting point for lifestyle changes and medications if needed. In the meantime, adopt a heart-healthy lifestyle, and do it with friends and family no matter their ages. Theres no time like the present to prevent heart disease.
Hdl: The Good But Complex Cholesterol
More HDL cholesterol is better, but the benefits may depend on how you get there.
In the simplest telling of the cholesterol story, HDL fights LDL . Like knights in shining armor, HDL particles patrol the blood vessels, snatching cholesterol from circulating LDL particles and from the dangerous, gooey plaque that lines artery walls. The knights of the HDL cholesterol carry their fatty cargo to the liver for recycling or disposal.
The real story isn’t quite so simple. HDL cholesterol is turning out to be a much more complex substance than we once believed. Instead of a single kind of particle, HDL cholesterol is a family of different particles. Although they all contain lipids , cholesterol, and proteins called apolipoproteins, some types are spherical while others are doughnut-shaped. Some types of HDL are great at plucking cholesterol from LDL and artery walls while other types are indifferent to cholesterol, and some even transfer cholesterol the wrong way into LDL and cells.
To further complicate matters, different HDL types do more than just carry cholesterol. Some protect LDL from being chemically altered by oxygen, a change that makes LDL extra harmful to artery walls. Under some circumstances, though, they can do just the opposite. Various HDL particles can ease inflammation in artery walls, stimulate production of nitric oxide, a molecule that helps artery walls relax, and help prevent blood clots from forming inside arteries.

Interpreting Hdl Cholesterol Levels
HDL levels below 40 mg/dL are associated with an increased risk of CAD, even in people whose total cholesterol and LDL cholesterol levels are normal. HDL levels between 40 and 60 mg/dL are considered “normal,” and do not very much affect the risk of CAD one way or the other. However, HDL levels greater than 60 mg/dL are actually associated with a reduced risk of heart disease.
In other words, the dogma has been: the higher the HDL levels, the better.
While this belief is still thought to be almost always true, in recent years a fly has been found in the ointment. Drug companies have spent billions of dollars developing drugs that increase HDL cholesterol levels. However, to the dismay of all, these drugs have failed to reduce cardiac riskdespite the fact that they make HDL levels go up. Development of at least two of these drugs has now been halted. So the HDL story is more complex than scientists originally had hoped.
How Long Does It Take For Consumed Foods To Help Lower Bad Cholesterol
A 2015 study from Penn State University found that obese or overweight people had a 50% drop in LDL levels after following an avocado-rich, low-fat diet for five weeks. An earlier study from Mexico reported that a similar diet in healthy people with mild hypercholesterolemia reduced total cholesterol by 17% and “bad” LDL cholesterol by 22% after only seven days.

Foods To Boost Your Good Cholesterol
These delicious foods and drinks pack a heart-healthy punch.
It’s likely that you’ve heard of the term “cholesterol” before, and you’re not alone if it makes you feel a little confused. From the low-fat diet era to the current day keto-lovers, there seems to be mixed messaging around cholesterol and how it impacts your health.
For starters, let’s define it. Cholesterol is a fat-like substance in our blood that our body needs to help make hormones, synthesize vitamin D, digest food and more. Since it’s fat-like and waxy in texture, too much cholesterol in our blood can lead to plaque formation and narrowing of our blood vessels, which can lead to heart disease.
But not all cholesterols is the samethere are two main types: low-density lipoproteins and high-density lipoproteins . LDLs are often referred to as “bad” or “lousy” cholesterol, as they are more likely to accumulate in our blood vessels. HDLs are coined the “good” or “helpful” cholesterol because they pick up excess cholesterol in the blood, including LDLs, and bring it to the liver where it can be broken down and excreted.
Cholesterol Test Results Chart: What Is Considered High
In addition to looking at total cholesterol number, it’s important to consider your LDL and HDL levels. Here’s what’s considered normal and high cholesterol for men and women over the age of 20:
Total cholesterol levels below 200 milligrams per deciliter is ideal for adults, while a reading above 240 mg/dL is considered high.
For LDL levels, the lower the number, the better. LDL levels should be less than 100 mg/dL.
For HDL levels, the higher the number, the better. HDL levels are best when they’re more than 60 mg/dL. Talk to your doctor to interpret these numbers and set your personal goals.
If you’re under the age of 20, normal or high cholesterol levels look a bit different:
Children between the ages of 9 and 11 should have their cholesterol checked once before puberty, according to the CDC, and then once again between the ages of 17 and 21. More screenings may be necessary for children and adolescents with diabetes or obesity, as they can be at a higher risk.

You Dont Need To Avoid Eggs And Seafood
Some foods are high in cholesterol but are fine to eat in moderation, as long as your overall diet is low in saturated fats. For example:
- Egg yolks a single egg yolk contains 200250 mg of cholesterol, which is almost the uppermost recommended daily intake . However, reducing egg intake is probably not important for healthy people with normal blood cholesterol levels.
- Seafood prawns and seafood contain some cholesterol, but they are low in saturated fat and also contain healthy omega-3 fatty acids. Seafood is a healthy food and should not be avoided just because it contains cholesterol. However, avoid fried and battered seafood.

Regulation Of Cholesterol Synthesis
Biosynthesis of cholesterol is directly regulated by the cholesterol levels present, though the homeostatic mechanisms involved are only partly understood. A higher intake from food leads to a net decrease in endogenous production, whereas lower intake from food has the opposite effect. The main regulatory mechanism is the sensing of intracellular cholesterol in the endoplasmic reticulum by the proteinSREBP . In the presence of cholesterol, SREBP is bound to two other proteins: SCAP and INSIG-1. When cholesterol levels fall, INSIG-1 dissociates from the SREBP-SCAP complex, which allows the complex to migrate to the Golgi apparatus. Here SREBP is cleaved by S1P and S2P , two enzymes that are activated by SCAP when cholesterol levels are low.
Cholesterol synthesis can also be turned off when cholesterol levels are high. HMG-CoA reductase contains both a cytosolic domain and a membrane domain. The membrane domain senses signals for its degradation. Increasing concentrations of cholesterol cause a change in this domain’s oligomerization state, which makes it more susceptible to destruction by the proteasome. This enzyme’s activity can also be reduced by phosphorylation by an AMP-activated protein kinase. Because this kinase is activated by AMP, which is produced when ATP is hydrolyzed, it follows that cholesterol synthesis is halted when ATP levels are low.
Hdl Versus Ldl Cholesterol
There are two main types of cholesterol: high-density lipoprotein and low-density lipoprotein . Lipoproteins are made of fat and proteins. Cholesterol moves through your body while inside lipoproteins.
HDL is known as good cholesterol because it transports cholesterol to your liver to be expelled from your body. HDL helps rid your body of excess cholesterol so its less likely to end up in your arteries.
LDL is called bad cholesterol because it takes cholesterol to your arteries, where it may collect in artery walls. Too much cholesterol in your arteries may lead to a buildup of plaque known as atherosclerosis. This can increase the risk of blood clots in your arteries. If a blood clot breaks away and blocks an artery in your heart or brain, you may have a stroke or heart attack.
Plaque buildup may also reduce blood flow and oxygen to major organs. Oxygen deprivation to your organs or arteries may lead to kidney disease or peripheral arterial disease, in addition to a heart attack or stroke.
Centers for Disease Control , over 31 percent of Americans have high LDL cholesterol. You may not even know it because high cholesterol doesnt cause noticeable symptoms.
The only way to find out if your cholesterol is high is through a blood test that measures cholesterol in milligrams per deciliter of blood . When you get your cholesterol numbers checked, youll receive results for:
To treat high cholesterol, doctors often recommend these lifestyle changes:

How High Is Too High
Very high HDL cholesterol levels not only don’t protect you more, but they might be harmful. In one study, people who had HDL cholesterol levels above 60 mg/dL were nearly 50% more likely to have a heart attack or die from heart disease than people whose HDL levels were between 41 and 60 mg/dL.
Why might higher HDL levels be harmful? Researchers don’t know for sure, but they have some ideas.
Very high HDL levels could slow the process of clearing LDL cholesterol from your arteries. When LDL cholesterol builds up in these blood vessels, it forms clumps called plaques that slow or block blood flow. Eventually a chunk of plaque can break free and form a clot, which could lead to a heart attack or stroke.
Work In Some More Movement To Your Daily Tasks
Do you need to start running every day? Do you need to join a gym or buy a bunch of home fitness equipment? If you want to, go ahead! But there are many other choices, and finding a routine that works for you is whats most important.
Ideally, you want to aim for at least 2.5 hours of moderate physical activity every week. You can break that up however you like. You might focus on doing something every day, or you could dedicate yourself to just a few days per week. The key is to just get started.
For example, do you usually take the elevator? Take the stairs instead. Do you walk your dog every day? Go a little farther than usual, or walk at a faster pace. Need to go shopping? Park farther away than you normally do. Catching up on your favorite TV series? Try stretching, dumbbells or kettlebells while youre watching rather than just sitting on the couch. Also look for chances to bring motion into your daily life, such as walking while you talk on the phone.
If youre feeling good, work up to more intense physical activity, like lap swimming, jogging or hot yoga. Dont overexert yourself, but remember that regular and consistent exercise has benefits beyond managing your cholesterol. It also helps reduce blood pressure and builds your overall physical, mental and emotional well-being.
Even if you just go a little farther or a little faster than you usually do, that extra activity will be a big step in the right direction for your health.

Effects Of High Cholesterol Levels
The liver is the main processing centre for cholesterol and dietary fat. When we eat animal fats, the liver transports the fat, together with cholesterol in the form of lipoproteins, into our bloodstream.
Too much cholesterol circulating within LDL in our bloodstream leads to fatty deposits developing in the arteries. This causes the vessels to narrow and they can eventually become blocked. This can lead to heart disease and stroke.
What Causes High Cholesterol
Some causes of high blood cholesterol include:
- Low intake of foods containing healthy fats healthy fats tend to increase the good cholesterol.
- High intake of foods containing unhealthy fats such as fatty meats, full-fat dairy products, butter, coconut oil, palm oil and most deep-fried takeaway foods and commercially baked products . Foods high in trans-fats include most commercially baked products and deep-fried takeaway foods.
- Low intake of foods containing fibre foods that are high in dietary fibre, particularly soluble fibre, can reduce the amount of LDL cholesterol in your blood. Include fibre-containing foods in your diet by choosing vegetables, fruits, wholegrains, nuts and seeds every day.
- Cholesterol in food this has only a small effect on LDL cholesterol -saturated fats and trans-fats in food have a much greater effect.
- You can also eat up to 7 eggs a week as part of a healthy, balanced diet low in saturated and trans-fats, without increasing your risk of heart disease.
Some people will have high cholesterol even if they follow a healthy, balanced diet low in saturated fats and trans-fats. These people may need to take cholesterol-lowering medicine as prescribed by their doctor.

Which Is The Good Cholesterol
Cholesterol can be a silent killer. While the substance is flowing through your blood and clogging your arteries, there are few signs of a problem. That is, until a heart attack or stroke occurs.
Cholesterol is one of the most important risk factors for cardiovascular disease, says Indu Poornima, MD, a cardiologist with Allegheny Health Network in Pittsburgh. Unless checked by a blood test, it will never be detected.
Left untreated, abnormal cholesterol levels can lead to atherosclerosis , which can slow or block blood flow to the heart.
Thats the bad news. But theres an upside too.
Not all cholesterol is created equal, and one type can actually improve your health and lower your risk of heart problems. Thats right: as important as it is to prevent your LDL cholesterol from soaring, its just as crucial to make sure your protective HDL cholesterol is high enough.
Heres what you need to know about this good cholesterol, target numbers to aim for, and what to do if your number is too low.
These Are The Best Ways To Raise Your Good Cholesterol
Good cholesterol is also known as HLD cholesterol and it refers to high-density lipoproteins. The high-density lipoproteins pick up excess cholesterol in your blood and take it back to your liver where its broken down.
So basically the more HDL cholesterol your have in your blood, the less bad cholesterol can be found there.
Its very important to permanently boost your good cholesterol levels, so try to make some changes in your lifestyle. Here is how you can start!
1. Get active. Physical activity will boost your good cholesterol level, so you should get at least 45 minutes a day of moderate activity, most days of the week.
Try walking in the park, running or cycling if you dont want to get in the gym and start training harder.
2. Lose weight. Excess weight is very dangerous and it will increase the LDL cholesterol level. Losing extra pounds will help you stay fit and boost the HDL.
3. Quit smoking. Smoking will reduce the good cholesterol in your blood and will tire your body, so if you already have this bad habbit try to get rid of it as soon as possible.
Instead you can try sipping cold water all day long and have small meals and snacks.
