Whats the difference between high cholesterol due to poor diet, and high cholestoral that had been inherited?

Q. My doctor has recently put me on medication having just found out that I have high cholesterol and he believes it has very little to do with my diet and is genetic. My father is on medication for high cholesterol that he inherited from his father, I was just wondering how he was able to tell, and what the difference between the two is?

Additional information: He is my own doctor, not a family doctor. He also did a range of tests, including checking my salt, sugar and iron levels, which were all ok. So I assumed he was able to tell I have a good diet based on this and the fact my good cholesterol was fine, just wondering if there was a difference between the two.

A. There is no difference between high cholesterol from diet or inherited high cholesterol. It is the same cholesterol, and it has the same health effects. You cannot tell the difference between them based on blood tests or clinical signs.

The only potential difference is that if someone has a diet that is obviously high in cholesterol, then they may be able to lower their cholesterol relatively easily by making modifications to their diet. However, if your diet is not very high in cholesterol then any minor modifications you can make to your diet will be unlikely to reduce your cholesterol significantly.

Your doctor wasn't able to tell for sure that your cholesterol is inherited, but he is making an educated guess by asking you about your diet and from looking at your family history.

where can i find a good diet and rescipes to help combat high chloresterol and high triglycerides?

Q.

A. triglycerides are a tough one as your body can produce this when eating a large amount of fruit. weird but true. Taking an Omega 3 supplement helps with triglycerides too.
Also, generally any low fat, high fiber diet will help but adding oat bran to your diet is suppose to really work better so that means adding oatmeal or Cheerios as a breakfast food is a good thing.
Be aware that your body produces a certain amount of cholesterol itself and for some people, no matter what they eliminate from their diet, they still have high cholesterol counts and those folks need to take a medication for that.

What is a safe level of cholesterol and at what level does it start getting dangerous?

Q. My mum just had a blood test and her cholesterol level was 8.3. Is that dangerously high?

A. ALL studies show that women will live longer with high cholesterol, up to 400, than they will with cholesterol in the normal range.
This from Weston A Price foundation.
Cholesterol is not the cause of heart disease but rather a potent antioxidant weapon against free radicals in the blood, and a repair substance that helps heal arterial damage (although the arterial plaques themselves contain very little cholesterol.) However, like fats, cholesterol may be damaged by exposure to heat and oxygen. This damaged or oxidized cholesterol seems to promote both injury to the arterial cells as well as a pathological buildup of plaque in the arteries.50 Damaged cholesterol is found in powdered eggs, in powdered milk (added to reduced-fat milks to give them body) and in meats and fats that have been heated to high temperatures in frying and other high-temperature processes.

High serum cholesterol levels often indicate that the body needs cholesterol to protect itself from high levels of altered, free-radical-containing fats. Just as a large police force is needed in a locality where crime occurs frequently, so cholesterol is needed in a poorly nourished body to protect the individual from a tendency to heart disease and cancer. Blaming coronary heart disease on cholesterol is like blaming the police for murder and theft in a high crime area.

Poor thyroid function (hypothyroidism) will often result in high cholesterol levels. When thyroid function is poor, usually due to a diet high in sugar and low in usable iodine, fat-soluble vitamins and other nutrients, the body floods the blood with cholesterol as an adaptive and protective mechanism, providing a superabundance of materials needed to heal tissues and produce protective steroids. Hypothyroid individuals are particularly susceptible to infections, heart disease and cancer.51

what is triglyceride in the blood?

Q. Is there a direct relationship between heart stroke and blood triglyceride levels?

A. This Article will help you out in understanding :

Triglycerides" is the chemical name for fat. Chemically, triglycerides have a three-carbon backbone (glycerol) to which are attached fatty acids, which are strings of carbon and hydrogen atoms, most of which will eventually be oxidized to carbon dioxide and water, producing energy in the process. When not being actively oxidized or metabolized, triglycerides are stored in adipose, or fatty tissue, for oxidation at a later time. High levels of triglycerides in the blood have been associated with increased risk for heart attacks and strokes. Triglycerides may be increased by heredity, abdominal obesity, resistance to insulin, diabetes, and certain medications. They may be decreased by weight loss, control of glucose in diabetes, decreased simple sugar intake in the diet, and increased activity.

Is it ok to give young children the margarine that lowers your cholesterol absorption?

Q. I have very slightly raised LDL, but my total cholesterol is fine...thought the special margarine that lowers cholesterol would be a good idea for me...can I give it to my 2 and 4 yr old?

A. I wouldn't personally, growing kids need the fat for their brains to develop.

It's just butter so I don't think its a big deal if you buy two different kinds.

wat is the process of of triglyceride absorption after digestion, from the small intestine?

Q.

A. Triglycerides are broken down into free fatty acids and glycerol by pancreatic lipase. They then enter the enterocytes in the small intestine where they are re-esterified into triglycerides and packaged into chylomicrons (which are composed of proteins, phospholipids, triglycerides, etc). The chylomicrons enter the lymphatic system via the lacteal. The chylomicrons are broken down in the lymph vessels by lipoprotein lipase and the fats are taken up by tissues that need it.

my triglycerides are high what does this mean?

Q. I don't even know what they are but the dr told me the levels were a bit high, I can't even spell it

A. Triglycerides are fatty acids, there are 'good' ones and 'bad' ones, your doc was probably referring to the 'bad' ones. You will find 'good' fatty acids in oily fish and avocados, these ones are very good for you. You will find 'bad' ones in animal fat including dairy products.

I recommend making these simple changes to your diet in order to limit your intake of 'bad' fatty acids;

Cut the fat off your meat before you cook it,
Buy the lean/heart smart meats,
Avoid deep fried food,
Swap butter for margarine,
Use oil when cooking instead of butter,
Cut back on soft cheeses,

You may also like to serve yourself slightly less meat and more vege to compensate.

Hope this helps

What to feed chickens to lower cholesterol?

Q. I read on a previous posting that it is what you feed the chickens that increases or lowers the cholesterol content. Unfortunately there was no mention on what you should feed them. I have noticed that some chicken feed contains blood and bone, and that would obviously play a role. Is there anything else I should be aware of? Please note I do not live in the USA so please do not give brand names.
Sorry am talking about lowering the cholesterol content of the egg.
JD, would that affect the egg?

A. To lower cholesterol, you would want to lower the fat content of what you are feeding since cholesterol is found in the fat. If you are referring to meat birds and you mean that you need to lower the cholesterol in your diet, you can do that by not eating the fat and skin of the chicken.

What is a known natural substance for lowering cholesterol?
Q. Apart from eating all the right foods and excersing what is a good natural proven substance I can take to lower cholesterol? I dont want to take Statin Drugs.

A. oatmeal, cheerios (but in HUGE quantities), anything with good whole fiber...i also like flax oil capsules, which have lots of good omega 3s and 6s but don't make me have fish burps (like the fish oil capsules do).

phytostearols are a naturally occuring substance in a lot of fruits and vegetables said to help, can be easily found in said items, but also in enough quantity to help in pomegranate juice and a new yogurt-shot drink type thing from promise (but the name escapes me as of this moment). right in the grocery store.

by all means, DO try all of these methods first before ever going on a statin! also know, if your levels aren't extremely high, that some people's bodies just make more cholesterol naturally than others, regardless of how good their diet is.

How to cook a low cholesterol Christmas dinner?
Q. My father has recently been diagnosed with angina and this means cutting down on cholesterol. He loves his food and I don't want him to miss out on christmas dinner so i am wondering if anyone had any recipes and tricks to make the whole dinner, with all the trimmings. I am from the UK.

A. Try using Fry Light, its an alternative to oil. Its a spray that you could cover your spuds in instead of more traditional fats for roasting. Cook Turkey as its a very lean meat and again use the fry light to cover instead of more traditional fats. Make sure he eats breast meat without the skin on. For the veg either steam or boil them.

The fry light does make food a little dryer but it does a great job - use some good herbs and it will still be tasty.

why is it dangerous to have Implanon when you have high cholesterol?

A. Hi
There is a question as to whether Implanon increases cardiovascular risk factors including C-reactive protein, a marker of inflammation.

The following recent study suggests that there is no risk:

What is medically most advised for patients with exceptionally high cholesterol readings from drawn blood?
Q. What diet makes it betfer? What medications have the history of being of most help?

A. Diet low in saturated fats which would mean cutting out red meat, butter, also other fats like fried foods, cheese, etc.
Remember this rule: Cholesterol is made in the liver, therefore any food that comes from an animal contains cholesterol as it is made in the liver. Fish is the best thing to eat because it has good fats that lower cholesterol. Chicken, baked, not fried is low in fat but not totally fat free. You should really try a vegetarian diet.
a diet high in fiber lowers cholesterol by taking it out of the body,
fiber is in fruits and vegetables, and high fiber cereals such as bran and shredded wheat, also oatmeal is high in fiber.
As for meds, the statins such as simvastatin or rosuvastatin are often recommended.
Also the the B vitamin niacin may be recommended.
Red rice yeast can be purchased over the counter, it has the same properties as the statin drugs.

How does a vegetarian raise their hemoglobin, hemotocrit and HDL cholesterol?
Q. I'm 26 years old and I participate in drug studies for a living and recently got rejected from one because my hemoglobin and hemotocrit were too low. My HDL cholesterol was too low as well. I'm thinking this is because I'm a recent vegetarian... its been about 5 months since I've stopped eating animal flesh. Otherwise, I'm healthy. I don't smoke and my BMI is a low 19.

Since getting rejected, I've started taking a multivitamin with iron, started drinking one glass of red wine each night (to help increase my HDL) and started exercising every day as well. Any thoughts on what else I could be doing that I'm not already? I want to screen for another study in a week or so.

A. Your HDL is effected by your intake of saturated vs. unsaturated fats and your exercise level. Your hemoglobin is directly related to your intake of iron. Your hematocrit should not be low unless you've experienced blood loss, or your diet is very insufficient of protein and iron.

It's very important that you get adequate protein despite being a vegetarian. You might try soy products or even protein supplement shakes. Green leafy veggies (spinach is great and yummy fresh or cooked!) have lots of iron. For your HDL, make sure you are getting enough physical exercise. Also make sure the majority of the fat you are taking in is unsaturated. The red wine is an acceptable supplement, but won't do much on it's own.

Hope this helps! Best wishes!

What is the difference between a triglyceride and a phospholipid?

Q. What is the difference between a triglyceride and a phospholipid? How does this difference account for the hydrophobic and hydrophilic nature of phospholipids?

A. I'm doing this at A-level now, are you?

We did this today...

A Phospholipid is Glycerol + 2 Fatty acids + 1 Phosphoric Acid

In a condensation reaction, this produces 1 phospholipid, and 3 water molecules.

The phosphate part of this has OH groups, which can form hydrogen bonds with water.
The fatty acid parts don't have Oh groups, so they are hydrophobic.

A triglyceride is made up of glycerol + 3 fatty acids (the phosphoric acid is replaced by another fatty acid, in comparison to the formula for phospholipid).

Because the phosphate part contained the OH group in the phospholipid, and it is absent in this molecule, triglyceride can not form hydrogen bonds, and so is hydrophobic.

hope this helps, i know research can be tricky, often there's either not enough, or too much more advanced information.

What can I do as a woman after menapause do to improve on my Cholesterol and Triglyceride blood results?
Q. In April 2006 my blood work showed: Cholesterol 167.6; Triglyceride 220.4 and HDL 38.1. I am talking Lipitor during both of these blood tests.
In October 2006 my blook work showed: Cholesterol 211.1; Triglyceride 143.7 and HDL 48.5.
I listed the HDL because I was afraid the Lipitor was effecting my Good Cholestrol count.
I'm looking for someone that can tell me why my cholestrol went up this time and triglycerides went down and what is my next course of action.

A. Eat cabbage, oatmeal, apples, etc. for soluble fiber and of course some type of exercise.

Also, here's some all-natural supplements that are very effective.

OmegaGuard: reduces the risk of heart disease/stroke, lowers triglycerides and cholesterol

Soluble Fiber (e.g. Fiber Plan): prevents fat absorption; reduces stress on heart by minimizing fat accumulation

Lecithin: converts serum cholesterol to good HDL

CoQHeart: Reduces LDL oxidation

Garlic Complex: prevents clotting; dilates small blood vessels; dissolves fatty deposits & thins blood

Hope this is useful and feel free to contact me with questions.

What determines whether a triglyceride is saturated or unsaturated?
Q. Is it the bonds?

A. A trigylceride (fat) is basically a glycerol molecule joined to three fatty acid molecules. The fatty acid molecules are often called "fatty acid chains" or "fatty acid tails".

Triglyceride structure:
http://www.indiana.edu/~oso/Fat/FatImg/triglyceride.jpg

If a triglyceride contains fatty acid tails with only single bonds in their structure, it is said to be saturated (saturated with hydrogens - it contains the maximum no. of C-H bonds).

If a triglyceride contains one or more fatty acid tails which contain at least one double bond in their structure, it is said to be unsaturated.

Here is a pic which shows the difference between saturated and unsaturated fats:
http://www.realfitnessblog.com/wp-content/uploads/2008/11/fat_f2.jpg

As the pic above shows, saturated fats are usually straight, so the molecules can pack together tightly, which is why saturated fats are solids at room temp. The double bonds in the structure of unsaturated fats makes kinks in the chain preventing the neat packing together of these molecules, so most unsaturated fats are liquids at room temp.

Where is Low density lipoprotein (LDL) & High density lipoprotein (HDL) synthesized?

Q. Could you also let me know
1. HOW and WHERE they are removed from the bloodstream and
2. Dietary and lifestyle factors that may increase or decrease the amount in the blood (please explain).

I have been researching but I didn't find much.

A. Mostly the liver makes LDL and HDL which are fats/cholesterol..
You can stop eating cholesterol for the rest of your life and still have high levels. How can this be? For starters, all of your cells can create cholesterol. This is good because every cell in your body needs it to form protective membranes. Your body actually monitors your cells, and if it senses that a cell doesn't have enough cholesterol, it will produce more. Cholesterol also is an essential building block for naturally produced vitamin D and other good stuff, like estrogen and testosterone. But even though every cell can make its own cholesterol, some cells need extra help with their supply. This is where your liver comes in.
Your body, mainly your liver, produces 75 percent of your cholesterol; your small intestine also aids in both the creation and absorption of cholesterol [source: AHA]. The average diet adds another 300 to 500 mg of cholesterol [source: Schafer]. This external cholesterol comes from animal and dairy products. But even if you eat foods without cholesterol, the carbs, fats and proteins all break down eventually and release carbon, which your liver turns into cholesterol.

Q. Could you also let me know
1. HOW and WHERE they are removed from the bloodstream and
2. Dietary and lifestyle factors that may increase or decrease the amount in the blood (please explain).

I have been researching but I didn't find much.

A. HDL cholesterol "scavenges" your bad cholesterol and helps to eliminate LDL from the body. The only nonpharmacologic way to increase your HDL is to exercise.

Ingesting more soluble fiber lowers your LDL cholesterol because soluble fiber binds bile in the GI tract and it gets eliminated. Bile is synthesized using LDL, so that's why you sometimes see advertising on the side of quaker oats that they can lower your cholesterol. I believe the recommendation is to get 20-30 g of fiber / day.

Would it be better to fry a high fat food in Olive oil? cnsidring olive oil is a High-Density Lipoprotein.....
Q.

A. It can be used successfully for frying but be aware that the strong flavor of olive oil will still transfer to whatever you are cooking. If the food you are preparing is already high in fat, it won't make much of a nutritional difference at all. When you fry something at the correct temperature, very little of the oil should still be left on the food after cooking. It actually uses the moisture aleady present in the food to cook it. That is why you see the bubbles coming up. If the oil is too cool, it will soak into the food and make it greasy. Don't get me wrong, frying still adds a lot of fat and calories.


Check out this website which will tell you everythig you need to know about cooking with, storing, buying, and using olive oil. It's a great resource.

What happens if too much Low density Lipoprotein is in the bloodstream?

Q.

A. They call it "bad cholesterol" for a reason, because it's known that LDL causes vascular inflammation which triggers defense cells to form fibrin and collagen around the lipid deposits creating atheromas. When an atheroma breaks lose, you can get many life threatening conditions, from heart attacks to strokes.

Sometimes if an atheroma doesn't break, it can still cause both before mentioned entities if it fully clogs the blood vessel.

How is cholesterol good for you and your body?

Q. Explain the benefits of cholesterol for the body and its functions. How does it affect joints and organs?

A. Americans are being saturated with anti-cholesterol propaganda. If you watch very much television, you're probably one of the millions of Americans who now has a terminal case of cholesterol phobia. The probaganda is relentless and is often designed to produce fear and loathing of this works of all food contaminants. You never hear the food propagandists bragging about their product being fluoride free or aluminum free, two of our truly serious food-addidtive problems. But cholesterol, an essential nutrient not proven to be harmfull in ANY quantity is constantly pilloried as a menance to your health. If you don't use corn oil, Fleishmann's margarine and Egg Beaters, you are going straight to atherosclerosis hell with stroke, heart attack and premature aging and so are your kids.

William Campbell Douglass, MD
Eat Your Cholesterol

How much Cholesterol should you be taking in every day?
Q. I started reading food labels, and I noticed there's a line called Cholesterol with a number in mg's. How many mg's or what is the total amount of cholesterol per day that is recommended for a 20 something female? Thanks.

A. Officially, experts say you shouldn't have over 300mg (based on a 2,000 calorie diet). I tend to think that's a little high and try to not go over half that. It really depends on your age and activity level. Maybe the link below will help a little more.

How much cholesterol is in egg whites as opposed to the yolks?
Q. One of my co-workers told me that there are equal amounts of cholesterol in both the white and the yolk.

I told her that wasn't true because the yolk is what has all the calories, fat, and cholesterol in it, so I'm doing a good thing by eating egg white omelettes, as opposed to regular ones that include the yolk.

Or am I? Who's right?

A. Your coworker is an idiot. There is zero cholesterol in the white.

But the yolk has good stuff, too, like iron and omega fatty acids, so don't skip it all the time.

Where is Low density lipoprotein (LDL) & High density lipoprotein (HDL) synthesized?

Q. Could you also let me know
1. HOW and WHERE they are removed from the bloodstream and
2. Dietary and lifestyle factors that may increase or decrease the amount in the blood (please explain).

I have been researching but I didn't find much.

A. Mostly the liver makes LDL and HDL which are fats/cholesterol..
You can stop eating cholesterol for the rest of your life and still have high levels. How can this be? For starters, all of your cells can create cholesterol. This is good because every cell in your body needs it to form protective membranes. Your body actually monitors your cells, and if it senses that a cell doesn't have enough cholesterol, it will produce more. Cholesterol also is an essential building block for naturally produced vitamin D and other good stuff, like estrogen and testosterone. But even though every cell can make its own cholesterol, some cells need extra help with their supply. This is where your liver comes in.
Your body, mainly your liver, produces 75 percent of your cholesterol; your small intestine also aids in both the creation and absorption of cholesterol [source: AHA]. The average diet adds another 300 to 500 mg of cholesterol [source: Schafer]. This external cholesterol comes from animal and dairy products. But even if you eat foods without cholesterol, the carbs, fats and proteins all break down eventually and release carbon, which your liver turns into cholesterol.

why would chylomicron, low-density lipoprotein, and high-density lipoprotein form a spherical shape?
Q. not sure if this is important:
chylomicron has 4% phospholipid, 90% triacylglycerol, 5% cholesterol, 1% protein.
low-density lipoprotein has 20% phospholipid, 10% triacylglycerol, 45% cholesterol, 25% protein.
high-density lipoprotein has 30% phospholipid, 5% triacylglycerol, 20% cholesterol, 45% protein.

A. Particles (and systems in general) always follow the "principal of least energy" which reduces the free energy of a system to minimum.

Phospholipids are polar compounds based upon a glycerol backbone. Two fatty acids are attached to the phospholipid at the sn-1, and sn-2 position (end and middle respectively). Both fatty acids are non-polar and hydrophobic (water-hating). The third spot is taken by a polar group at the sn-3 position (e.g. the other end) which is hydrophilic (water loving). In addition to polar amino acids and proteins, the outer side of the lipoprotein particles face the water while the hydrophobic portions point inward, where triglycerides, cholesterol and cholesterol esters are.

The hydrophilic outer portion allows lipoprotein particles to stay suspended in serum and blood. The inner lipid and sterol portion attract each other and form a stable system.

The shape that reduces free energy to a minimum is a sphere so lipoprotein particles assume that shape.

Without the phospholipids and proteins surrounding the water-insoluble portions, the lipid and sterol molecules would simply coalesce, which would result in blobs of fat accumulating in the circulatory system.

I would like know about high density lipoprotein cholesterol range?

Q. High Density Lipoprotein Cholesterol (HDL-C) is known as "good" cholesterol, so if we have high HDL- C that is better for our hearts. But I don't know how high HDL-C is good. For example, my brother is 47years old. His HDL-C is 82mg/dl. I wonder it is good? Would you please help me to find out the answer. Thank you very much for your time.

A. 60 mg/dL or higher- is considered protective against heart disease.
Less than 40 mg/dL for men- is too low
Less than 50 mg/dL for women- is too low
Of course too low is a major risk factor for heart disease
So, with this guideline set by the American Heart Association even...Your brother is doing just wonderfully. Good Luck!!

How is the high density lipoprotein formed? And where specifically?
Q. Where does it come from?

A. It is made mainly near the blood vessels around the body, but the precursors come from the liver.

http://www.nature.com/nrd/journal/v4/n3/fig_tab/nrd1658_F2.html

How does HDL (High density lipoprotein) reduce the risk of atheroma formation,and Coronary Heart Disease?
Q. and what is the effect of low concentration of HDL inside the blood?

A. HDL carries cholesterol from the body tissues to the liver.

Lower HDL levels result in more cholesterol in blood leading to increased risk of atheroma formation,and Coronary Heart Disease.

What does it mean if my triglyceride is low?

Q. I am a young adult and recently had a blood test taken. My triglyceride level was a low 26, the norm is 35-160. What does this mean and what are the risks of having a low amount? Also, what is the function of triglyceride and how can I raise it?

A. Triglycerides are the form that dietary fat takes in your blood. You do not want to raise your trigylceride level because it can lead to heart disease and other health complications. Its best to keep it low.

Can triglyceride levels in dogs increase from the chewing/eating of rawhide?
Q. I have increased the amount of rawhide chews I give to my Beagle, and coincidentally, her triglycerides soared. Is there any connection between the two? Otherwise, she is fed Nutro Ultra for Seniors dry mixed with a little bit of canned and water for a sauce. She is not fed fats, and has a healthy diet of fruits and veggies for snacks.

A. most raw-hides are deep fried or oven basted with chicken fat as dripping, so are just full of fat. You can get healthier ones if you search, but they cost more. Most people recommend the nylon bones, but I have heard if they are too small the dogs can swallow them whole, then you will need an operation.

I give my dogs a small healthy meaty bone to chew daily, its part of their breakfast calorie, is natural and much lower in fat.

Why is a triglyceride considered hydrophobic when it has a glycerol molecule which is hydrophilic?
Q. also- can everything be categorized as hydrophilic and hydrophobic?

lastly- if the outside of our membranes is hydrophilic wouldn't we dissolve in water?

A. The hydroxyl group of glycerol joins in an ester linkage with the carboxyl group on the lipid leaving a hydrophilic compound.

Not all compounds are one or the other some are amphiphilic with a polar hydrophilic end and a nonpolar lipophilic hydrocarbon end like the phospholipids in cell membranes.

what foods contain high density lipoproteins (HDL's)?
Q. I heard that cholesterol isnt bad if it is packed with hdl's. So I want my diet to have more HDL's since its high in cholesterol.

A. Egg whites are a great source of HDLs. But only about 10% of your cholesterol comes from diet, the other 90% comes from synthesis by the liver, controlled by genetics. The best way to increase your HDL's is to exercise.

Do we need both HDL (High-density lipoprotein) and LDL (Low-density lipoprotein)?
Q. If so, then how do vegans exist?

A. The liver and the intestines both form lipoproteins such as HDL, LDL, IDL and VLDL. Levels of each are determined by multiple factors. For example, the fats that are carried by the lipoprotein particles come from food and from fat synthesized by the liver.

Eating foods high in cholesterol actually has little effect of serum cholesterol levels(1). The body has a sensitive feedback mechanism that tightly regulates the production of cholesterol (2). When dietary consumption of cholesterol increases, less is produced by the liver. High levels of insulin increase the synthesis of cholesterol by the liver and also by individual cells in the body.

Fats do have an effect on the levels of HDL, LDL and VLDL. Saturated fats strongly increase HDL and to a lesser estent, LDL. Polyunsaturated fats tend to lower both HDL and LDL. A higher refined carbohydrate intake can strongly increase the serum levels of triglycerides, which can also increase LDL. The liver produces primarily palmitic and palmitoeic acid from carbohydrates. Palmitic acid is also the predominant fatty acid in animal.

Since production of HDL, LDL and triglycerides is mediated by many factors, it is impossible to make many generalizations about the association of dietary fats and carbohydrates and serum cholesterol. Very low carbohydrate diets can result in a more favorable lipid profile than a low fat diet (3). Strict meat eaters can have a fairly low serum choleserol while vegans can have a higher serum cholesterol. People eating a paleolithic diet and a vegan diet can have similarities, in so much that both ways of eating discourage the consumption of vegetable seed oils, refined carbohydrates and favor eating whole foods.

a study reported that the prevalence of hyperlipidemia is 30% in children 2 to 6 years of age. if 12 children?

Q. are analyzed: a) what is probability that at least 3 are hyperlipidemia? b) what is the probability that exactly 3 are hyperlipidemic? and c) how many would be expected to meet the criteria for hyperlipidemia?

A. a. ANSWER: PROBABILITY = 0.75 at least 3 are hyperlipidemia

Why???

BINOMIAL DISTRIBUTION, POPULATION PROPORTION
n = NUMBER OF TRIALS [ 12] (sample size)
k = NUMBER OF SUCCESSES [2] (from 0 up to and including k NUMBER OF SUCCESSES)
p = POPULATION PROPORTION [30%]

significant digits2

COMPUTATION OF BINOMIAL PROPORTION:
P(k => 3) = 1 - P(k ⤠2) = 1 - n!/[k!*(n - k)!] * p^k * (1 - p)^(n - k)
0.75 = 12!/[2!*(12 - 2)!] * 0.3^2 * (1 - 0.3)^(12 - 2)

ALTERNATIVE COMPUTATION USING EXCEL:
"Look-up" value of PROBABILITY = 0.75 = 1 - BINOMDIST ( 2 , 12 , 30/100 , TRUE )
"Using Excel function: BINOMDIST(number_s, trials, probability_s, cumulative)
Number_s is the number of successes in trials. [ 12 ]
Trials is the number of independent trials. [ 2 ]
Probability_s is the probability of success on each trial. [ 30]"

Cumulative is a logical value that determines the form of the function. If cumulative is TRUE, then BINOMDIST returns the cumulative distribution function, which is the probability that there are at most number_s successes; if FALSE, it returns the probability mass function, which is the probability that there are number_s successes.



b. ANSWER: PROBABILITY = 0.24 exactly 3 are hyperlipidemic

Why???

BINOMIAL DISTRIBUTION, POPULATION PROPORTION
n = NUMBER OF TRIALS [ 12] (sample size)
k = NUMBER OF SUCCESSES [3] (Exactly 3 NUMBER OF SUCCESSES)
p = POPULATION PROPORTION [30%]

significant digits2

COMPUTATION OF BINOMIAL PROPORTION:
P(k = 3) = n!/[k!*(n - k)!] * p^k * (1 - p)^(n - k)
0.24 = 12!/[3!*(12 - 3)!] * 0.3^3 * (1 - 0.3)^(12 - 3)

ALTERNATIVE COMPUTATION USING EXCEL:
"Look-up" value of PROBABILITY = 0.24 =BINOMDIST ( 3 , 12 , 30/100 , FALSE )
"Using Excel function: BINOMDIST(number_s, trials, probability_s, cumulative)
Number_s is the number of successes in trials. [ 12 ]
Trials is the number of independent trials. [ 3 ]
Probability_s is the probability of success on each trial. [ 30]"

Cumulative is a logical value that determines the form of the function. If cumulative is TRUE, then BINOMDIST returns the cumulative distribution function, which is the probability that there are at most number_s successes; if FALSE, it returns the probability mass function, which is the probability that there are number_s successes.



c. ANSWER: (approx) 4 children expected to be hyperlipidemic

Why???
SAMPLE SIZE * POPULATION PROPORTION = EXPECTED [12 * 0.3 = (approx) 4]

Hyperlipidemia is 30% in children 2-6 years of age. If 12 children are analyzed, what is the probabilty that?
Q. At least 3 are hyperlipidemic?

A. Well, four kids out of twelve should have it. But your question isn't very specific. If you have three kids, and you wanna know what their odds of getting it are, it depends.
Family history is an important factor, but if you're going by statistics alone, one of your kids probably has it.

age 25 and diagnosed with hyperlipidemia?
Q. I ws diagnosed with hyperlipidemia since i was 22. I tried to watch what I eat, but with no luck. I turned 25, and couple weeks ago, I went for a physical, and I was told that my cholesterol was 249. That 's high!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I know I need to excercise, but I'm really lazy. I have normal weight,and dance as excercise sometimes. Can someone please help me choose a good diet? I want to know what exactly can cut my cholesterol?

A. Low fat, high fiber diet. More vegies than fruit to help lose weight. The fiber helps carry fat out of the body so it is not absorbed.

With normal weight, you can eat more fruit, and whole grains. Minimal processed foods that list hydrogenated anything. That boosts LDL (bad stuff), and lowers HDL (good stuff). Cut way back on meats, especially beef, and cut back or eliminate fried foods.

Is there a Low density lipoprotein(LDL) and High density lipoprotein (HDL) reader available in the market?

Q.

A. LDL and HDL are determined by Photometry method in a Pathological Laboratory.You are required to give a blood sample for this.
Full Blood profile consists of TC,HDL,TG and LDL.

Ldl is 196 triglycerides 154 hdl 31 hdl ratio 8 ldl ratio 6.3 very low density lipoprotein 30.8 my age is 44?
Q.

A. LDL- High LDL level, corresponding to much higher rates for developing symptomatic cardiovascular disease events
Triglyceride- Slightly above normal.
HDL- Low HDL cholesterol, heightened risk for heart disease.
VLDL- slightly above normal.
Risk for cardiac disease is assessed by dividing the total cholesterol level by the HDL level. Target values are <5 for men and <4.4 for women.
Take statin drug in consultation with your doctor.
Also control your cholesterol level by diet and exercise. You may also take omega-3 fatty acid (fish oil).
Adopt DASH diet (Mediterranean diet). Eat a low-cholesterol, low-fat diet, which includes cottage cheese, fat-free milk, fish, vegetables, poultry, and egg whites. Use monounsaturated oils such as olive, peanut, and canola oils or polyunsaturated oils such as corn, safflower, soy, sunflower, cottonseed, and soybean oils. Avoid foods with excess fat in them such as meat (especially liver and fatty meat), egg yolks, whole milk, cream, butter, shortening, pastries, cakes, cookies, gravy, peanut butter, chocolate, olives, potato chips, coconut, cheese (other than cottage cheese), coconut oil, palm oil, and fried foods.
Please note that I am not a medical professional.

where is Low density lipoprotein (LDL) & High density lipoprotein (HDL) synthesized?

Q. Could you also let me know
1. HOW and WHERE they are removed from the bloodstream and
2. Dietary and lifestyle factors that may increase or decrease the amount in the blood (please explain).

I have been researching but I didn't find much.

A. HDL cholesterol "scavenges" your bad cholesterol and helps to eliminate LDL from the body. The only nonpharmacologic way to increase your HDL is to exercise.

Ingesting more soluble fiber lowers your LDL cholesterol because soluble fiber binds bile in the GI tract and it gets eliminated. Bile is synthesized using LDL, so that's why you sometimes see advertising on the side of quaker oats that they can lower your cholesterol. I believe the recommendation is to get 20-30 g of fiber / day.

why would chylomicron, low-density lipoprotein, and high-density lipoprotein form a spherical shape?
Q. not sure if this is important:
chylomicron has 4% phospholipid, 90% triacylglycerol, 5% cholesterol, 1% protein.

high-density lipoprotein has 30% phospholipid, 5% triacylglycerol, 20% cholesterol, 45% protein.

A. Particles (and systems in general) always follow the "principal of least energy" which reduces the free energy of a system to minimum.

Phospholipids are polar compounds based upon a glycerol backbone. Two fatty acids are attached to the phospholipid at the sn-1, and sn-2 position (end and middle respectively).

How is cholesterol calculated and can you have too much good cholesterol?

Q. I went to the doctor and my cholesterol was 246 which isn't so good but my good cholesterol was 65, which she said is great. Is the LDL what's remaining after the good cholesterol is subtracted from the total? Can you have too much HDL?

A. HDL are "high-density lipoproteins" which is fancy doctor talk for cells that are high in protein, low in fat/cholesterol. This is preferred, as this is what "feeds" the body with growth proteins. Proteins power "cell" creation and repair (only). Things like muscle, skin, hair, etc...anything that grows or requires frequent repair benefit from higher counts of HDL. HDL's increase in demand with more activity. Specifically 'cardio' (meaning heart) workouts. You really can't have "too much" HDL's because if the body doesnt need the level of proteins in the blood sugar, it simply release it as it passes through the kidneys. We pee out excess proteins. They do NOT convert to bodyfat like some bodybuilders like to beleive.

LDLs are of course "Low density", meaning low protein high fat. LDL's partially provide energy to "active" muscles. The cells are often "coated" with saturated fats. As these move around the body feeding active muscles, they 'bump along' the artery walls, the leave little "skid marks" so to speak. These marks build up to become plaque, and can cause heart decrease. Reducing LDL's to under 200, (or 150 even better) would be good advice but often requires medication, diet modification, AND more physical activity.

How much cholesterol would be in a ostrich egg?
Q. Actually, you can eat ostrich eggs. Eggs are eggs. Just to let you know.

How is cholesterol good for you and your body?
Q. Explain the benefits of cholesterol for the body and its functions. How does it affect joints and organs?

A. Americans are being saturated with anti-cholesterol propaganda. If you watch very much television, you're probably one of the millions of Americans who now has a terminal case of cholesterol phobia. The probaganda is relentless and is often designed to produce fear and loathing of this works of all food contaminants. You never hear the food propagandists bragging about their product being fluoride free or aluminum free, two of our truly serious food-addidtive problems. But cholesterol, an essential nutrient not proven to be harmfull in ANY quantity is constantly pilloried as a menance to your health. If you don't use corn oil, Fleishmann's margarine and Egg Beaters, you are going straight to atherosclerosis hell with stroke, heart attack and premature aging and so are your kids.

How is cholesterol calculated and can you have too much good cholesterol?

Q. I went to the doctor and my cholesterol was 246 which isn't so good but my good cholesterol was 65, which she said is great. Is the LDL what's remaining after the good cholesterol is subtracted from the total? Can you have too much HDL?

A. HDL are "high-density lipoproteins" which is fancy doctor talk for cells that are high in protein, low in fat/cholesterol. This is preferred, as this is what "feeds" the body with growth proteins. Proteins power "cell" creation and repair (only). Things like muscle, skin, hair, etc...anything that grows or requires frequent repair benefit from higher counts of HDL. HDL's increase in demand with more activity. Specifically 'cardio' (meaning heart) workouts. You really can't have "too much" HDL's because if the body doesnt need the level of proteins in the blood sugar, it simply release it as it passes through the kidneys. We pee out excess proteins. They do NOT convert to bodyfat like some bodybuilders like to beleive.

LDLs are of course "Low density", meaning low protein high fat. LDL's partially provide energy to "active" muscles. The cells are often "coated" with saturated fats.

Is cyclying good for reducing triglyceride level?
Q. I am having a triglyceride of 548. I cycle for 7Kms. daily. Is this good or I should necessarily walk instead of cycling ?

A. Triglycerides > 500 are targeted for treatment first because the increased risk for pancreatitis. Exercise alone will not be sufficient to reduce your triglycerides. In fact, elevated triglycerides will not give an accurate reading for LDL, HDL, etc.... [If you think the lab results are inaccurate, you can always get another lab done].

More than likely, your doctor has probably prescribed mediction (or a supplement such as fish oils with a titration schedule).

Medications used are:
1) Fibrates - fenofibrates, tricor, etc.... (
2) Trilipix - only one with FDA approval to be used in combination with a statin
3) Lovaza
4) Fish Oils
5) Niaspan - used to increase HDL but can also be used to decrease TG

Talk to you doctor for additional information.

What does it mean if my triglyceride is low?
Q. I am a young adult and recently had a blood test taken. My triglyceride level was a low 26, the norm is 35-160. What does this mean and what are the risks of having a low amount? Also, what is the function of triglyceride and how can I raise it?
