Ldl Cholesterol
Question: How does saturated fat raise HDL cholesterol levels and mono/poly-unsaturated fat raise LDL? I am looking for the biological explanation of how the intake of saturated fat triggers the production of HDL cholesterol. What happens inside the body that raises HDL cholesterol level? Likewise with the mono/poly unsaturated fat and LDL cholesterol levels.
Really? Nobody knows?

Question: Does reducing your LDL cholesterol actually reduce the amount of fibrous plaque in your arteries? Although people are always going on about good/bad cholesterol and the ability to affect blood cholesterol levels, does the reduction of LDL intake actually help to remove, or allow an opportunity for removing already formed fibrous plaques etc which are blocking arteries, or are you stuck with these regardless and must simply limit the damage that has already been done?
Answer: I think its mainly a case of damage limitation;
Question: How can my LDL cholesterol be above norm, but my triglycerides are only at 56? Shouldn't they work together? Hello! My LDL cholesterol is 123, which is in the "Near Optimal" Range (100 is Optimal), but my triglycerides are pretty low at only 56. Shouldn't those two things work in the same direction, like both high or both low? I eat all kinds of food, but I don't eat a lot, I'm pretty slim.
Answer: LDL cholesterol and triglycerides do not necessarily correlate with one another, because they are controlled by completely different mechanisms. Diet is only one factor in high LDL cholesterol and triglycerides. There are several enzymes in the body that also regulate the levels of LDL and triglycerides. In my experience, usually when the LDL is elevated so is the triglycerides, but it is not necessarily the case. Poor dietary habits such as excess saturated fats can contribute to the elevation of high LDL and triglycerides, but remember there are other things regulating their levels.
The goal LDL cholesterol is dependent on your risk factors for heart disease and is a little complicated. I do not know if you have any or not. If you do not have any, then your goal LDL is less than 160. Therefore your LDL would be absolutely perfect. If you have two or more risk factors for heart disease then your goal LDL is less than 130. An LDL goal of is recommended for people with multiple risk factors for heart disease or if they have known heart disease, diabetes, chronic kidney disease or history of stroke. If someone is very high risk for heart disease, then the goal LDL would be less than 70. An example would be someone with diabetes and known heart disease. I do not know your risk factors so I cannot comment on this. A triglyceride value of is actually very good. Good luck.
Question: can eating egg white only increase your LDL cholesterol? If you eat everyday egg white for the breakfast, does it inclease your LDL, total cholesterol or triglycerides?
Answer: No .cause it contain proteins .yolk contain cholesterol
Question: How do I lower my LDL cholesterol? I'm 26 and my doctor told me I have an elevated LDL cholesterol level. It is at 176. He wants me to excercise and eat right. What types of food should I eat and do you have any recommended excercises or activities?
Answer: If you want to lower your cholesterol naturually there are a variety of foods that reduce cholesterol, including specific fruits, vegetables and nuts. See which foods researchers have determined are cholesterol-busters.
If you are looking for away to lower your cholesterol, but want to avoid a high-priced prescription with possible side effects, you have options. Nature has provided a variety of foods that scientists have found can effectively reduce cholesterol levels.
Question: How do i lower my LDL Cholesterol? I work at a hospital where we have to take cholesterol tests. I recently found out I have a LDL cholesterol level of 120. My HDL level was 50. I am also Hypoglycemic. I don't know if that has anything to do with cholesterol. How do I lower my LDL cholesterol?
With out drugs. And if I could get a simple life of what to eat and what not to eat that would be apreciated.
Answer: Pretty simple stuff really,reduce your animal fat intake,increase your intake of oily fish (omega 3 oils) and take regular exercise,to have an effect it has to be vigorous. The hypoglycaemia is irrelevant and usually does not indicate any real pathology.
Question: The difference between HDL and LDL cholesterol? I am a graphic designer and I have to illustrate a Low Density Lipoprotein (LDL) and a High Density Lipoprotein. I understand the difference between the two: LDL is bad, HDL is good etc, but am finding it difficult to understand what the difference in appearance would be. What does a LDL look like next to a HDL? Does the HDL have more Apoprotein? Do the cholesterol molecules look the same in each? Is there the same amount of cholesterol in each? Is it just the actual 'density' of the lipoprotein that is different (so should I make the components of the HDL look more 'clustered'?). I am illustrating these concepts for the general public, so any ideas about how I can express this in an easy to understand way would be appreciated! Also, not quite sure what the difference is between the cholesterol esters (inside the lipoprotein) and the cholesterol that is located around the edge of the lipoprotein amongst the Apoprotein? Are they the same in both LDL and HDL?
Thanks!
Answer: HDL collects cholesterol from around the body and takes it to the liver
LDL collects cholesterol from the liver nad takes it to cells of the body
there are several types of lipoproteins the lower the density the the more fat and less protein there is in the cell, higher density = more protein, less fat

Heyy guys
Im doing my homework and im having a bit of trouble , i feel really under the weather so i was wonedring if i could have some help with this question?
Please , I'll be Oh so greatful!
Answer: LDL stands for low-density lipoprotein. It is a wax like substance which builds up on the inside of the arteries that feed the heart and brain. Together with other substances, it can form plaque, a thick, hard deposit that can narrow the arteries and make them less flexible. Think of gook which clogs the pipes in your house. You have to call a plumber to clean them out. This condition is known as atherosclerosis. If a clot forms and blocks a narrowed artery, heart attack or stroke can result. The effect is to reduce area space in which blood can flow. If it gets severe, it deprives the body of oxygen, since oxygen is carried by the blood. It comes from dairy products and beef.
HDL is high-density lipoprotein. Medical experts think that HDL tends to carry cholesterol away from the arteries and back to the liver, where it's passed from the body. Some experts believe that HDL removes excess cholesterol from arterial plaque, slowing its buildup.

Question: Why is my LDL cholesterol increasing? After being diagnosed with high cholesterol, I increased exercise a bit but changed my diet drastically, nearly following the dietary recommendations to a T. After six months of this, my HDL has risen nicely and triglycerides have gone down a bit, but my LDL has gone up 20 points (about 10%)! Now my total cholesterol is higher than before, and I can't understand why.
Answer: To answer this question properly I would need to know what dietary changes you have made, but I reckon I could guess.
We will assume that you have cut back on fats, and as such will have increased carbohydrate intake.
Now to try to understand the mechanisms of the subject of cholesterol.
First and foremost, the measurements are not of cholesterol, they are of Low Density Lipoproteins(LDL) High Density Lipoproteins (HDL) and Very Low Density Lipoproteins (VLDL, but erroneously called Triglycerides). A true triglyceride is three fatty acids attached to a glycerol molecule. Whenever I refer to a VLDL, it is what you know as a triglyceride, which contains a high proportion of triglycerides. Confusing isn't it? And I'm sure that is deliberate.Missing from this list are chylomicrons and Intermediate Density Lipoproteins (IDLs)
A lipoprotein is what carries cholesterol and lipids (fat), in the form of triglycerides, around the body, as they are not water soluble.
When you digest fat in the small intestine they are packed into chylomicrons,along with dietary cholesterol,.Chylomicrons have Appolipoproteins added to the outside which act like identifiers. As this chylomicron travels around the body, cells with the appropriate receptor to the appolipoprotein take the triglycerides from the chylomicron. Once most of the triglycerides are gone, it has become a chylomicron remnant, containing mainly cholesterol and is absorbed by the liver thus delivering dietary cholesterol to the liver. No VLDL (erroneously and confusingly called triglyceride) or LDL in this pathway.
When you consume excess carbohydrates the liver will convert the excess blood glucose into triglycerides (real triglycerides, not VLDL) and pack them into VLDLs, along with cholesterol. It has one different appolipoprotein (identifier) added to it and sent out via the bloodstream.
Again, cells with the appropriate receptor will take triglycerides from the VLDL, which will become a IDL, and as it loses most (true) triglycerides, eventually an LDL, An LDL consists of mainly cholesterol and a few triglycerides. It's function is now to provide cholesterol to the cells that need it.
If no cells need any cholesterol, there will be no cells with the appropriate receptor, and the LDLs remain in the blood.
So in your case, again assuming your carb intake has increased, you are producing more VLDLs (erroneously and confusingly called triglycerides) , but your increase in exercise means that there is more demand for their contents, so they are converted into LDLs. There is however, no increase in demand for cholesterol, so now you have elevated levels of LDLs, yet lower VLDLs (erroneously and confusingly called triglycerides)
HDLs are separate again, and not really relevant to the point I'm trying make
I know this is confusing so to summarise;
Digested fat is packed into Chylomicrons, transferred to cells, and the remnant absorbed by the liver.-Gone from the bloodstream completely
Fat created by the liver , maily due to high blood sugars, Is packed into VLDLs ( what you know as triglycerides) and transferred to cells that need it, thus becoming LDLs.
If no cells need cholesterol, Then LDLs stay in the blood.
The whole idea that lowing fat consumption will lower your cholesterol levels is just plain wrong. No study has ever shown this to be case, and the science shows how flawed this idea is, Literally thousands of people are told to do this, which doesn't work and then end up on cholesterol lowering drugs.
"In Framingham, Massachusetts, the more saturated fat one ate, the more cholesterol one ate, the more calories one ate, the lower people's serum cholesterol...” Dr William Castelli 1992 (Director of the Framingham study, that extensive study of which many contort the results to promote the low fat anti cholesterol ideas)
"The Atkins dieters had significantly greater increases in good cholesterol (HDL) and greater decreases in triglycerides"
http://health.upenn.edu/News/News_Releases/May03/Foster.html
I challenge anyone who doesn't agree with this to prove me wrong, not just give it the thumbs down. Otherwise you are simply admitting that you too have been conned, but don't have the courage to admit it.
Question: What LDL Cholesterol level is consider risk fator? My friend just have the blood test, The Triglycerides is 170,
The normal range is 30-150
What is level of LDL and Triglycerides is consider risk factor and may face heart attack.
Answer: Your Total Blood (or Serum) Cholesterol Level
Less than 200 mg/dL: Desirable
If your LDL, HDL and triglyceride levels are also at desirable levels and you have no other risk factors for heart disease, total blood cholesterol below 200 mg/dL puts you at relatively low risk of coronary heart disease. Even with a low risk, however, it’s still smart to eat a heart-healthy diet, get regular physical activity and avoid tobacco smoke. Have your cholesterol levels checked every five years or as your doctor recommends.
200–239 mg/dL: Borderline-High Risk
If your total cholesterol falls between 200 and 239 mg/dL, your doctor will evaluate your levels of LDL (bad) cholesterol, HDL (good) cholesterol and triglycerides. It's possible to have borderline-high total cholesterol numbers with normal levels of LDL (bad) cholesterol balanced by high HDL (good) cholesterol. Work with your doctor to create a prevention and treatment plan that's right for you. Make lifestyle changes, including eating a heart-healthy diet, getting regular physical activity and avoiding tobacco smoke. Depending on your LDL (bad) cholesterol levels and your other risk factors, you may also need medication. Ask your doctor how often you should have your cholesterol rechecked.
240 mg/dL and over: High Risk
People who have a total cholesterol level of 240 mg/dL or more typically have twice the risk of coronary heart disease as people whose cholesterol level is desirable (200 mg/dL). If your test didn’t show your LDL cholesterol, HDL cholesterol and triglycerides, your doctor should order a fasting profile. Work with your doctor to create a prevention and treatment plan that's right for you. Whether or not you need cholesterol-regulating medication, make lifestyle changes, including eating a heart-healthy diet, getting regular physical activity and avoiding tobacco smoke.
HDL- High Density cholesterol
With HDL (good) cholesterol, higher levels are better. Low HDL cholesterol (less than 40 mg/dL for men, less than 50 mg/dL for women) puts you at higher risk for heart disease. In the average man, HDL cholesterol levels range from 40 to 50 mg/dL. In the average woman, they range from 50 to 60 mg/dL. An HDL cholesterol of 60 mg/dL or higher gives some protection against heart disease.
Smoking, being overweight and being sedentary can all result in lower HDL cholesterol. To raise your HDL level, avoid tobacco smoke, maintain a healthy weight and get at least 30–60 minutes of physical activity more days than not.
People with high blood triglycerides usually also have lower HDL cholesterol and a higher risk of heart attack and stroke. Progesterone, anabolic steroids and male sex hormones (testosterone) also lower HDL cholesterol levels. Female sex hormones raise HDL cholesterol levels
Your LDL (Bad) Cholesterol Level
The lower your LDL cholesterol, the lower your risk of heart attack and stroke. In fact, it's a better gauge of risk than total blood cholesterol. In general, LDL levels fall into these categories
LDL Cholesterol Levels
Less than 100 mg/dL
Optimal
100 to 129 mg/dL
Near Optimal/ Above Optimal
130 to 159 mg/dL
Borderline High
160 to 189 mg/dL
High
190 mg/dL and above
Very High
Your other risk factors for heart disease and stroke help determine what your LDL level should be, as well as the appropriate treatment for you. A healthy level for you may not be healthy for your friend or neighbor. Discuss your levels and your treatment options with your doctor to get the plan that works for you.
Your Triglyceride Level
Triglyceride is a form of fat. People with high triglycerides often have a high total cholesterol level, including high LDL (bad) cholesterol and low HDL (good) cholesterol levels.
Your triglyceride level will fall into one of these categories:
Normal: less than 150 mg/dL
Borderline-High: 150–199 mg/dL
High: 200–499 mg/dL
Very High: 500 mg/dL
Many people have high triglyceride levels due to being overweight/obese, physical inactivity, cigarette smoking, excess alcohol consumption and/or a diet very high in carbohydrates (60 percent of more of calories). High triglycerides are a lifestyle-related risk factor; however, underlying diseases or genetic disorders can be the cause.
The main therapy to reduce triglyceride levels is to change your lifestyle. This means control your weight, eat a heart-healthy diet, get regular physical activity, avoid tobacco smoke, limit alcohol to one drink per day for women or two drinks per day for men and limit beverages and foods with added sugars. Visit your healthcare provider to create an action plan that will incorporate all these lifestyle changes. Sometimes, medication is needed in addition to a healthy diet and lifestyle.
A triglyceride level of 150 mg/dL or higher is one of the risk factors of metabolic syndrome. Metabolic syndrome increases the risk for heart disease and other disorders, includ
Question: What is the truth about egg yolks and high LDL cholesterol? I have read lots of conflicting information about this - high cholesterol in yolks but differing views about their consumption and method of cooking. Is the dried whole egg in shops a viable substitute?
Answer: Dried whole egg in shops cannot be a substitute. You can use egg white and discard egg yolk if you LDL is high. If it is normal you may take upto 4 eggs a week.
Question: How to lower my LDL cholesterol? I got my blood test back from the lab and found out that my LDL cholesterol levels were borderline from being over the limit. I think your max is 130 but i measured 133. What can i do to get my levels lower? Thanks.
Answer: I will speak from experience.
I had my lipids checked in March and my doctor wanted to prescribe meds to lower my cholesterol. I had heard that there were a lot of side effects with the drugs so I did not want to go that route unless absolutely necessary.
So I did some research on over the counter supplements that might help. The best data I could gather would lead me to a product called Cholestsure. I ordered a 3 month supply and took 3 to 4 capsules a day trying to never miss a day.
After 3 months I had my lipids checked again and was my doctor and I were very pleased. My LDL went from 153 to 95 (below 100 is optimum).
I am continuing to take the supplements and will have my lipids checked again in December.
I do suggest a diet high in fiber as well.
Cholestsure can be ordered online. I am providing a link to the dealer I use. They seem to have the best price and free shipping.
Question: How do you convert cholesterol HDL and LDL from English Standards to American Standards!?!?!?!?!?!? Ok, i just went to get my blood tested and i found out my HDL and LDL cholesterol level. The results were in English standards and i want to know how to convert it to American standards so i can compare with the ones I tested in America.
Ok that's it thankies!!! (in ADVANCE!)
Answer: American lipid tests are reported using metric units (mg/dL). I would think this is uniform worldwide.
Question: what is the different between cholesterol, HDL and LDL? when we go for blood test check, we see the cholesterol, HDL = (good fat) and LDL = (bad fat) I would like to know exactly what are the differences between these 3 catogories or types of fat?
are HDL and LDL type cholesterol as well? what is the function of each of them or come from what? and how to increase or reduce each of them? and what are the risk levels of each of them when higher or lower the optimal range? I will appreciate any advices..
many thanks in adavnce,
Answer: This is an incredibly detailed and long explanation. I'll try to cover the surface and find you some links.
HDL and LDL aren't cholesterol (C) themselves, think of them as cholesterol carrying "bottles". The third fat on you saw on your blood test was probably triglyceride (TG).
The different between HDL and LDL is simply how much "cholesterol ester"(CE) it has (it's actually much more complicated than that but let's keep it simple). CE are safer for the body since it doesn't damage things that it touches and HDL has more of it. While LDL has more C, which can damage other cells it touches.
The other issue is that LDL has marker on it's surface called APO-B100... this marker can get damaged easily by toxin. Once the marker is damaged the LDL can never come back to liver again. So now it is forced to roam around in the blood until it eventually dies and gives us a atherosclerosis. HDL can save the day by finding these dead and collecting the C from them before they cause any problems and returning it back to the liver.
TG are like storage forms of fat. It's what you think of when you talk about fat around the waist.
This was a really vague explanation. But I think I probably already lost most people, so saying more would be to no avail.
Hope that made sense, if you still have more specific questions drop me a message and i'll try to help.
