How Can I Lower My Ldl Cholesterol Without Medications
The first step in managing any case of high LDL is through adopting healthy, therapeutic lifestyle changes . The key to TLC is:
- Adjusting diet: Adopting specific, heart-healthy eating habits, such as the TLC diet, Mediterranean diet, or the Dietary Approaches to Hypertension eating plan can dramatically improve LDL levels. These limit intake of trans fats, salt, and cholesterol, while boosting healthy, unsaturated fats.
- Managing weight: If you’re overweight or obese, even moderate reductions in weight can help lower LDL. Incorporating healthier lifestyle habits, such as improving diet, sleep quality, and level of physical activity can make a big difference.
- Staying active: Ensuring that you’re getting enough physical activity will also help reduce LDL levels. Aiming for a bare minimum of 30 minutes a day of moderate exercise, such as taking daily walks or cycling, can help a great deal.
Where Does Cholesterol Come From
Cholesterol in your body comes from two main sources: your liver and your diet.
Your liver, other organs, and other cells in your body produce about 80 percent of the cholesterol in your blood.
The other 20 percent of cholesterol in your body is affected by the foods you eat. Foods high in trans and saturated fats can contribute to unhealthy cholesterol levels.
As you take in more of these fats, your liver compensates by reducing its own production of cholesterol and removing excess cholesterol. However, not everyone makes and removes cholesterol with the same efficiency.
Some people have genes that tell their liver to make extra cholesterol or to slow their bodys cholesterol removal process. If youve inherited these genes, you may have high cholesterol even if you dont eat foods that are rich in fat or cholesterol.
Only About 20% Of The Cholesterol In Your Bloodstream Comes From The Food You Eat Your Body Makes The Rest
Cholesterol has a bad reputation, thanks to its well-known role in promoting heart disease. Excess cholesterol in the bloodstream is a key contributor to artery-clogging plaque, which can accumulate and set the stage for a heart attack. However, the role of cholesterol in your body is not all negative.
To fully explain cholesterol, you need to realize that it’s also vital to your health and well-being. Although we measure cholesterol production in the blood, it’s found in every cell in the body. The Harvard Special Health Report Managing Your Cholesterol explains cholesterol as a waxy, whitish-yellow fat and a crucial building block in cell membranes. Cholesterol also is needed to make vitamin D, hormones , and fat-dissolving bile acids. In fact, cholesterol production is so important that your liver and intestines make about 80% of the cholesterol you need to stay healthy. Only about 20% comes from the foods you eat.
If you eat only 200 to 300 milligrams of cholesterol a day , your liver will produce an additional 800 milligrams per day from raw materials such as fat, sugars, and proteins.
Since cholesterol is a fat, it can’t travel alone in the bloodstream. It would end up as useless globs . To get around this problem, the body packages cholesterol and other lipids into minuscule protein-covered particles that mix easily with blood. These tiny particles, called lipoproteins , move cholesterol and other fats throughout the body.

Why Cholesterol Matters
Cholesterol circulates in the blood. As the amount of cholesterol in your blood increases, so does the risk to your health. High cholesterol contributes to a higher risk of cardiovascular diseases, such as heart disease and stroke. Thats why its important to have your cholesterol tested, so you can know your levels.
The two types of cholesterol are: LDL cholesterol, which is bad, and HDL, which is good. Too much of the bad kind, or not enough of the good kind, increases the risk cholesterol will slowly build up in the inner walls of the arteries that feed the heart and brain.
Cholesterol can join with other substances to form a thick, hard deposit on the inside of the arteries. This can narrow the arteries and make them less flexible a condition known as atherosclerosis. If a blood clot forms and blocks one of these narrowed arteries, a heart attack or stroke can result.
When it comes to cholesterol, remember: check, change and control. That is:
- Check your cholesterol levels. Its key to know your numbers and assess your risk.
- Change your diet and lifestyle to help improve your levels.
- Control your cholesterol, with help from your doctor if needed
High cholesterol is one of the major controllable risk factors for coronary heart disease, heart attack and stroke. If you have other risk factors such as smoking, high blood pressure or diabetes, your risk increases even more.
Baked Goods And Sweets
Cookies, cakes and doughnuts usually contain butter or shortening, making them high in saturated fat and cholesterol.
They also tend to be full of sugar, which can lead to high levels of blood triglycerides, an unhealthy blood fat that can be a risk factor for coronary heart disease.
Instead, make your desserts at home, choosing recipes that dont need shortening or lots of butter. This also allows you to modify recipes and cut down the amount of sugar used, to half or three-quarters the recommended amount. You can also enjoy baked fruit as a dessert, or substitute applesauce for eggs or butter in your baking.

You Need A Little Not A Lot
Cholesterol is in every cell in your body. You need cholesterol to help your brain, skin, and other organs do their jobs. But eating too much fat and cholesterol is a bad idea.
Cholesterol floats around in your blood and can get into the walls of the blood vessels. This can cause the blood vessels to get stiffer, narrower, or clogged. If the clogging gets worse over many years, it can cause a heart attack or stroke in adults.
Cholesterol can start to build up in childhood. Doctors can find out what your cholesterol level is by taking a little of your blood and testing it.

Nutrition & Health Info Sheets For Consumers
Nutrition & Health Info Sheets contain up-to-date information about nutrition, health, and food. They are provided in two different formats for consumer and professional users. These resources are produced by Dr. Rachel Scherr and her research staff. Produced by Hanee Park, BS, Rachel E. Scherr, PhD, Sheri Zidenberg-Cherr, PhD, Center for Nutrition in Schools Department of Nutrition, University of California, Davis, 2017.
Why Is Cholesterol Essential
Your body needs some cholesterol to work properly. For example, cholesterol is used to build cell walls and produce some hormones.
About three quarters of the cholesterol in your body is produced by your liver the rest comes from the food you eat.
Cholesterol is carried in the blood by lipoproteins. The main types of lipoproteins are high-density lipoprotein and low-density lipoprotein .

What Is A Good Ldl To Hdl Ratio
In general, the higher your HDL, and the lower LDL, the better off you are. Optimal cholesterol levels are determined by looking at the ratio of HDL cholesterol to total cholesterol. This is calculated by dividing total cholesterol score by your HDL result, so if your total score is 150, and your HDL is at 50, you’d score a 3:1.
Generally speaking, the higher this number, the higher the risk of heart problems. Doctors want to see a ratio below 5:1, with those below 3.5:1 considered ideal. Since lowering LDL causes total cholesterol numbers to drop, it promotes a better cholesterol ratio.
Healthy Eating Tips To Lower Cholesterol
As well as sticking to a varied and healthy diet, try these tips to help you manage your cholesterol:
- Limit takeaway foods to once a week .
- Limit salty, fatty and sugary snack foods to once a week .

- Use healthy oils for cooking some include canola, sunflower, soybean, olive , sesame and peanut oils.
- Use salad dressings and mayonnaise made from oils such as canola, sunflower, soybean, olive , sesame and peanut oils.
- Include 2 or 3 serves of plant-sterol-enriched foods every day .
- Have 2 to 3 portions of oily fish every week. Fish may be fresh, frozen or canned.

Cholesterol Levels: What You Need To Know
How do we diagnose high cholesterol?
Lipoprotein panel is a type of blood test that can measure cholesterol levels. Before the test, the patient may need to fast for 9-12 hours. The test gives information about different types of cholesterol:
- otal cholesterol: It shows the total amount of cholesterol in the blood. It includes both low-density lipoprotein cholesterol and high-density lipoprotein cholesterol.
- LDL cholesterol: It transports cholesterol particles throughout the body. LDL cholesterol is often called the bad cholesterol because it builds up in the walls of the arteries, making them hard and narrow.
- HDL cholesterol: It picks up excess cholesterol and takes it back to your liver.
- Non-HDL: This number is total cholesterol minus HDL. Non-HDL includes LDL and other types of cholesterol such as very lowdensity lipoprotein .
- Triglycerides: Another form of fat in the blood that can increase your risk for heart diseases, especially in women, is triglycerides.
Are You At Risk
HDL cholesterol is known as ‘good’ cholesterol. This is because HDL helps to remove cholesterol from your arteries by carrying cholesterol back to your liver for disposal.
LDL cholesterol is known as ‘bad’ cholesterol. This is because LDL leaves cholesterol in your arteries.
The total cholesterol test is a blood test that measures both HDL and LDL cholesterol. Your doctor may test your cholesterol level to help find out your risk of heart disease or stroke. Other risk factors such as high blood pressure, obesity, type 2 diabetes and smoking also need to be considered.

How Can I Prevent High Cholesterol
Here are a few things you can do to keep your cholesterol under control:
- Eat a healthy diet that includes lots of fruit, vegetables and whole grains.
- Limit drinks and foods that have a lot of fat or sugar, like sugary drinks, treats, and fried foods.
- Get plenty of exercise. Experts recommend at least 60 minutes every day!
Plasma Transport And Regulation Of Absorption
As an isolated molecule, cholesterol is only minimally soluble in water, or hydrophilic. Because of this, it dissolves in blood at exceedingly small concentrations. To be transported effectively, cholesterol is instead packaged within lipoproteins, complex discoidal particles with exterior amphiphilic proteins and lipids, whose outward-facing surfaces are water-soluble and inward-facing surfaces are lipid-soluble. This allows it to travel through the blood via emulsification. Unbound cholesterol, being amphipathic, is transported in the monolayer surface of the lipoprotein particle along with phospholipids and proteins. Cholesterol esters bound to fatty acid, on the other hand, are transported within the fatty hydrophilic core of the lipoprotein, along with triglyceride.
There are several types of lipoproteins in the blood. In order of increasing density, they are chylomicrons, very-low-density lipoprotein , intermediate-density lipoprotein , low-density lipoprotein , and high-density lipoprotein . Lower protein/lipid ratios make for less dense lipoproteins. Cholesterol within different lipoproteins is identical, although some is carried as its native “free” alcohol form , while others as fatty acyl esters, known also as cholesterol esters, within the particles.

What Medications Are Used To Reduce Ldl Cholesterol
There are several classes of drugs prescribed for high LDL. These include:
- Statins: These drugs inhibit the activity of enzymes in the liver that produce cholesterol, lowering LDL, while raising HDL. The most commonly prescribed types include Lipitor , Lescol , and Advicor , among many others.
- Cholesterol absorption inhibitors: This type of drug, most commonly available as Zetia and Vytorin , prevents the intestines from absorbing cholesterol.
- Bile acid sequestrants: By spurring the intestine to shed more cholesterol, drugs like Colestid , Welchol , and Questran help lower LDL levels.
- PCSK9 inhibitors: This newer class of cholesterol-lowering drug, available as Repatha and Praluent , has shown great promise in lowering LDL. These monoclonal antibodies inhibit proprotein convertase subtilisin/kexin 9 , a protein that regulates cholesterol levels.
- Adenosine triphosphate-citrate lyase inhibitors: In adults with genetic high cholesterol, or those with heart disease, ACL inhibitors like Nexletol and Nexlizet may be prescribed. These are combined with statins and lifestyle changes to improve LDL levels.
- Fibrates: Drugs of this type, such as Lopid andfenofibrate , primarily moderate triglyceride levels, though they can also lower LDL.
What Are Hdl Ldl And Vldl
HDL, LDL, and VLDL are 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. Different types of lipoproteins have different purposes:
- HDL stands for high-density lipoprotein. It is sometimes called “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 lipoprotein. It is sometimes called “bad” cholesterol because a high LDL level leads to the buildup of plaque in your arteries.
- VLDL stands for very low-density lipoprotein. Some people also call VLDL a “bad” cholesterol because it too contributes to the buildup of plaque in your arteries. But VLDL and LDL are different VLDL mainly carries triglycerides and LDL mainly carries cholesterol.

What Is The Function Of Cholesterol In The Body
Cholesterol is publicized as an antonym to health. However, it is a necessary nutrient for body function. Much of the needed cholesterol is obtained through foods such as meat and dairy, but it can also be made by the liver. Most people think cholesterol is a fat, but rather, it is a high molecular weight sterol. If cholesterol is so vital, what exactly is the function of cholesterol in the body?
Cholesterol Content Of Foods
If you have risk factors for heart disease, you should not consume more than 200 milligrams of cholesterol a day.
If you do not have risk factors for heart disease, you should limit your cholesterol intake to no more than 300 milligrams a day.
Use the following tables to check the cholesterol and fat content of the foods you eat. This will help you keep track of your daily cholesterol intake.
Note: Cholesterol is only found in animal products. Fruits, vegetables, grains and all other plant foods do not have any cholesterol at all.

Plant Sterols Can Lower Cholesterol Levels
Plant sterols are found naturally in plant foods including sunflower and canola seeds, vegetable oils and in nuts, legumes, cereals, fruit and vegetables. Some margarine and milks have concentrated plant sterols added to them. Margarines enriched with plant sterolslower LDL cholesterol in most people if the correct amount is eaten .
What Are The Different Types Of Cholesterol
Cholesterol does not travel freely through the bloodstream. Instead, it is attached or carried by lipoproteins in the blood. There are three types of lipoproteins that are categorized based upon how much protein there is in relation to the amount of cholesterol.
Low-density lipoproteins contain a higher ratio of cholesterol to protein and are thought of as the bad cholesterol. Elevated levels of LDL lipoprotein increase the risk of heart disease, stroke, and peripheral artery disease, by helping form cholesterol plaque along the inside of artery walls. Over time, as plaque buildup increases, the artery narrows , and blood flow decreases. If the plaque ruptures, it can cause a blood clot to form that prevents any blood flow. This clot is the cause of a heart attack or myocardial infarction if the clot occurs in one of the coronary arteries in the heart.
High-density lipoproteins are made up of a higher level of protein and a lower level of cholesterol. These tend to be thought of as good cholesterol. The higher the HDL to LDL ratio, the better it is for the individual because such ratios can potentially be protective against heart disease, stroke, and peripheral artery disease.
Very low-density lipoproteins contain even less protein than LDL. VLDL like LDL has been associated with plaque deposits.
Triglycerides may increase cholesterol-containing plaques if levels of LDL are high and HDL is low.
