What Is High Cholesterol And How Does It Affect Me

September 3, 2010 · Posted in cholesterol · Comment 

Cholesterol is a type of fat that is part of all animal cells. It is essential for many of the body metabolic processes, including hormone and bile production, and to help the body use vitamin D.

Cholesterol is more abundant in tissues which either synthesize more or have more abundant densely-packed membranes, for example, the liver, spinal cord and brain.


The liver is the main processing center for cholesterol. When we eat animal fats, the liver returns the cholesterol it can not use to our bloodstream and when there is too much cholesterol circulating in our bloodstream, it can build up into fatty deposits. These deposits cause the arteries to narrow and can eventually block the arteries completely, leading to heart disease and stroke.


Cholesterol is produced by the liver and it is also made by most cells in the body. It is carried around in the blood by lipoproteins. We need blood cholesterol because the body uses it to build the structure of cell membranes, to produce hormones like testosterone, adrenaline and estrogen and to aid the metabolism.


Types of Cholesterol

There are two types of cholesterol, good and bad, the difference between them is:

a. Low density lipoprotein (LDL) cholesterol called the bad cholesterol because it goes into the bloodstream and clogs up your arteries.


b. High density lipoprotein (HDL) cholesterol called the good cholesterol because it helps to take the bad cholesterol out of the bloodstream.


Cholesterol is transported towards peripheral tissues by the lipoproteins chylomicrons, very low density lipoproteins (VLDL) and low-density lipoproteins (LDL).

Risks associated with high triglycerides


According to the lipid hypothesis, abnormally high cholesterol levels (hypercholesterolemia), or more correctly, higher concentrations of LDL and lower concentrations of functional HDL are strongly associated with cardiovascular disease because these promote atheroma development in arteries (atherosclerosis). High cholesterol has also been linked to diabetes and high blood pressure.


Both heredity and diet have a significant influence on a person’s LDL, HDL and total cholesterol levels. Evidence strongly indicates that high cholesterol levels can cause narrowing of the arteries (atherosclerosis), heart attacks, and strokes.


Cholesterol in the bile can crystallize to form gall stones that may block the bile ducts. Cholesterol count also rises during pregnancy.


However, in recent years, scientists have come to realise that to decide whether an individual’s cholesterol levels are dangerous, these levels need to be considered in the light of the person’s overall risk of heart disease.The higher the risk of heart disease (for example, a male smoker with high blood pressure and diabetes), the greater the need to get cholesterol levels down.


Cholesterol tests

Cholesterol testing is recommended as a screening test to be done on all adults at least once every five years.


Foods that contain cholesterol

The cholesterol in your diet comes mainly from the saturated fats found in animal products. All foods from animals contain some cholesterol. Foods from plants do not contain cholesterol. Other sources of dietary cholesterol are full fat dairy foods, eggs and some seafood.


Safe blood cholesterol levels

Health authorities recommend that cholesterol levels should be no higher than 5.5mmols per liter. Approximately 50 per cent of adult Australians have a blood cholesterol level above 5mmols per liter. This makes high blood cholesterol a major health concern in Australia.


How to lower high cholesterol

The best way to maintain healthy levels of cholesterol in your diet is to limit foods high in saturated fats. Try to avoid: Fatty meats , full fat dairy products, processed meats like salami and sausages, snack foods like chips, most takeaway foods, especially deep fried foods, cakes, biscuits and pastries.


However the most important thing you can do to reduce your cholesterol level is to maintain a healthy lifestyle. You should try to:

a. Limit the amount of cholesterol-rich foods you eat.

Increase the amount and variety of fresh fruit, vegetables and wholegrain foods you have each day.

b. Choose low or reduced fat milk, yoghurt and other dairy products or have added calcium soy drinks.

c. Choose lean meat (meat trimmed of fat or labeled as heart smart).

d. Limit fatty meats, including sausages and salami, and choose leaner sandwich meats like turkey breast or cooked lean chicken.

e. Have fish (fresh or canned) at least twice a week. Replace butter and dairy blends with polyunsaturated margarines.

f. Include foods in your diet that are rich in soluble fiber and healthy fats, such as nuts, legumes and seeds.

g. Limit cheese and ice cream to twice a week.


Some studies have suggested that eating oats and legumes may lower LDL cholesterol. Food components like saponins (found in chickpeas, alfalfa sprouts and other foods) and sulphur compounds (like allicin found in garlic and onions) may also have a positive effect on cholesterol levels.


Plant sterols can lower cholesterol levels,these are

found naturally in plant foods including sunflower and canola seeds, vegetable oils and (in smaller amounts) in nuts, legumes, cereals, fruit and vegetables. Some margarine has concentrated plant sterols added to it. Plant sterol enriched margarines may help to lower LDL cholesterol.


Treatment for high cholesterol

Treatment of high cholesterol is aimed at lowering the low-density lipoproteins (LDL) or bad cholesterol, lowering triglyceride levels, and increasing the high-density lipoproteins (HDL) or good cholesterol.


Treatment will be most effective if it also includes appropriate diet, weight loss (if necessary) and physical activity.


The first steps in treating high cholesterol levels are: Regular physical activity and healthy eating.


There are also some foods that may help to lower cholesterol levels, particularly garlic, soya, oats, corn and selenium-enriched cereals.


Cholesterol-lowering foods are not suitable for children under five years or for pregnant or breastfeeding mothers.


Medication :Statin drugs work by interfering with the cholesterol-producing mechanisms of the liver and by increasing the capacity of the liver to remove cholesterol from circulating blood. Statins can lower LDL cholesterol by as much as 60 percent, depending on the drug and dosage.

The Startling Truth About Cholesterol

September 3, 2010 · Posted in cholesterol · Comment 

* Cholesterol is produced by almost every cell in the body.

* Cholesterol in cell membranes makes cells waterproof so there can be different chemistry on the inside and the outside of the cell.

* Define “good” and “bad” cholesterol.

LDL (low-density lipoprotein) cholesterol is known as “bad” cholesterol because it can build up in the walls of your arteries and form a thick, hard plaque that clogs your arteries and blocks the flow of blood to your heart and brain. HDL (high-density lipoprotein) cholesterol is called “good” cholesterol because it helps eliminate bad cholesterol from the body.

* Where does cholesterol come from in the body?

Your body produces cholesterol naturally. Your liver makes cholesterol, as do other individual cells throughout your body. Once cholesterol is produced, it can make its way into your bloodstream.

* What does this process mean to you?

Take the cholesterol your body makes and add it to the cholesterol you get from food. Now you can see how easily cholesterol can build up in your bloodstream and how your overall cholesterol level can increase.

* Cholesterol is nature’s repair substance, used to repair wounds, including tears and irritations in the arteries. Many important hormones are made of cholesterol, including hormones that regulate mineral metabolism and blood sugar, hormones that help us deal with stress, and all the sex hormones, such as testosterone, estrogen and progesterone.

* Cholesterol is vital to the function of the brain and nervous system. Cholesterol protects us against depression; it plays a role in the utilization of serotonin, the body’s “feel good” chemical. The bile salts, needed for the digestion of fats, are made from cholesterol.

* Cholesterol is the precursor of vitamin D, which is formed by the action of ultra-violet (UV-B) light on cholesterol in the skin.

* Cholesterol is a powerful antioxidant that protects us against free radicals and therefore against cancer. Cholesterol, especially LDL-cholesterol (the so-called bad cholesterol), helps fight infection.

Hyperlipidemia is a key factor associated with an increased risk of the development of cardiovascular disease. Also referred to as high cholesterol, dyslipidemia, and lipid disorder, hyperlipidemia is a

condition by which unhealthy levels of cholesterol circulate in the blood.

The human body obtains cholesterol in two ways:

up to 80% of the cholesterol is produced endogenously in the liver; the remainder is obtained from the diet in the form of animal products such as meats, fish, eggs, and dairy.

While there is not a readily accepted level of cholesterol in the human body that is considered ‘safe’, most clinical guidelines list Total Cholesterol levels under 200 mg/dl as desirable.

Eating healthy food is the first step toward health.

The next step is seeing to it that the body has optimal ability to digest and metabolize that food.

Fortunately, healthy food is much easier to digest and assimilate, especially when properly prepared so that the enzyme systems are intact. At Capture Your Health, we can identify supplements you might need to assist digestion, assimilation and absorption of food. You may benefit from beginning with a program to detox the body.

Myths & Truths about Cholesterol

Myth: People with high cholesterol are more prone to heart attacks.

Truth: Young and middle-aged men with cholesterol levels over 350 are slightly more at risk for heart attacks. Those who have cholesterol levels just below 350 are at no greater risk than those whose cholesterol is very low. For elderly men and women of all ages, high cholesterol is associated with a longer lifespan.

Myth: Cholesterol & saturated fat clog arteries.

Truth: There is very little cholesterol or saturated fat in the arterial plaque or clogs. Most of the material is a calcium deposit akin to lime and most of the fatty acids are

unsaturated.

Myth: Eating saturated fat and cholesterol-rich foods will cause cholesterol levels to rise and make people more susceptible to heart disease.

Truth: Many studies show no relationship between diet and cholesterol levels; there is no evidence that saturated fat and cholesterol-rich food contribute to heart disease. As Americans have cut back on saturated fat and cholesterol-rich foods, rates of heart disease have gone up.

Myth: Cholesterol-lowering drugs have saved many lives.

Truth: In the two most recent trials, involving over 10,000 subjects, cholesterol-lowering did not result in any improvement in outcome.

Myth: Countries that have a high consumption of animal fat and cholesterol have higher rates of heart disease.

Truth: There are many exceptions to this observation, such as France and Spain.

Furthermore, an association (called a “risk factor”) is not the same as a cause. In wealthy countries where people eat a lot of animal foods, many other factors exist that can contribute to heart disease.

Please contact your health care provider should you have any questions concerning cholesterol, and please know your numbers.

How The Foods You Eat Can Influence Your Cholesterol Levels

August 20, 2010 · Posted in cholesterol · Comment 

As a follow up to a previous article let’s go into detail about how the foods we eat can or cannot influence our blood cholesterol levels. The previous article about what you eat was influenced by watching a television program by which the host has to devour enormous amounts of food in a certain time period and often these foods have an extremely high in calories and fat among other things. You are left to wonder, “That can’t be healthy!” Hopefully that young man is not shaving years off his life for the benefit of our entertainment and TV ratings, but is he?

The scientific community has long debated over how dietary cholesterol (the foods we eat) affects the cholesterol our body naturally produces (also known as serum cholesterol). Numerous studies have concluded that in adult men the serum cholesterol levelis essentiallyindependent of the cholesterol intake over thewhole range ofnatural human diets. It was noted that it is probable that infants,children andwomen are similar. Serum cholesterol is a term that includes the total level of cholesterol that is found in the bloodstream. Measuring the level of total cholesterol includes identifying all types or classes of cholesterol that are found in the system. This helpful measurement makes it possible to determine if the balance between the HDL or good cholesterol and LDL or bad cholesterol is within acceptable limits. Dietary cholesterol comes from animal products in the diet, such as butter, meats, egg yolks, and dairy products. Blood cholesterol is the fatty substance that occurs naturally in the body and which is necessary for hormone production, cell metabolism, and other vital processes.

There are 2 main types of blood cholesterol, high density lipoprotein (HDL) and low density lipoprotein (LDL) as was previously mentioned. It is generally considered desirable to have high levels of HDL cholesterol and low levels of LDL cholesterol. Another component to add to this puzzle is triglycerides which are the chains of high-energy fatty acids that provide much of the energy needed for cells to function.Your liver produces your body’s cholesterol in fact your body needs cholesterol. However, there is a difference between the cholesterol made by the body and dietary cholesterol. The cholesterol that the liver produces is vital to strengthening the membranes of each and every cell in the body. The liver also processes the saturated fats and sugars we digest.

What does all this mean and what does all of that have to do with what we eat? Well, dietary cholesterol does contribute to your blood cholesterol levels. Excess amounts of foods high in saturated fats will raise blood cholesterol levels in some people, and contribute to the build up of plaque on the walls of the arteries and lead to atherosclerosis (hardening of the arteries). These fats from the foods you eat make it to your blood stream and by extension to your liver for processing. One of the main jobs of the liver is to make sure all the tissues of the body receive the cholesterol and triglycerides they need to function. Whenever possible (that is, for about 8 hours after a meal), the liver takes up dietary cholesterol and triglycerides from bloodstream. However the relationship between cholesterol and the concentration of blood cholesterol is not linear. For every additional 100mg of cholesterol consumed up to a total intake of 500mg per day, there is a 2-3% increase in the concentration of blood cholesterol. In contrast further increases in cholesterol intake beyond 500mg per day have little additional effect on the blood level. But remember it is the bad cholesterol that will lead to a heart attack or stroke so it is important to maintain a healthy diet. If you have cardiovascular disease, diabetes or a high low-density lipoprotein (LDL, or “bad”) blood cholesterol level, you should limit your dietary cholesterol intake to less than 200 mg a day. Your diet directly affects your heart health, especially when the diet consists of foods high in fat and cholesterol. Your body uses cholesterol for certain functions, but an excess can build up in arteries, restricting or even blocking blood flow to the heart or brain.

Now that young who entertains us by consuming a grilled cheese sandwich with 15 different kinds of cheeses or eating a 10 patty cheese burger with 3 lbs. of fries undoubtedly know what he is doing to his body and more than likely has a plan for offsetting all calories and fat he is ingesting, but don’t do that at home. That would like attempting to drive the Indianapolis Motor Speedway at 200 mph three days after you got your driver’s license, it is not advisable. Foods that are high incalories and fat taken in their recommended portions are not necessarily a bad thing, but like all things they should be consumed in moderation. Remember you are what you eat, so maintaining a healthy diet along with exercise can keep your cholesterol levels in check, healthy cholesterol equates to a healthy heart and that means a long and healthy life.

Lower Your High Cholesterol Naturally

August 10, 2010 · Posted in cholesterol · Comment 

Cholesterol is a substance that is similar to fat. It can be found in the cell membranes of all body tissues and is transported through the blood plasma. There is “bad cholesterol” and “good cholesterol” in the human body, and both of them are cholesterol carriers. “Bad” cholesterol carriers are low-density lipoprotein or LDL and deposit cholesterol in the artery walls, thus thickening them-a key cause of heart disease. “Good” cholesterol carriers are high-density lipoprotein or HDL and help to keep the arteries healthy by clearing cholesterol out of the system. When levels of “bad” cholesterol are high, treatment is imperative.

The American Heart Association and the National Cholesterol Education Program (NCEP) suggest that HDL levels should be around 60 mg/dL. If the HDL level count is less than 40 mg, the chances of coronary artery disease are greater. LDL cholesterol levels should be around 130 mg/ dL. A diet rich in saturated and trans fats and low in beneficial fats (monounsaturates and polyunsaturates) can lead to high LDL levels. Smoking, drinking large amounts of alcohol, other poor dietary habits and lack of exercise are all dangerous factors. These are lifestyle habits which need to be altered in the treatment of high cholesterol(http://www.mitamins.com/disease/High-Cholesterol.html).

If your total cholesterol level is less than 200 mg/dL, you are less likely to suffer from a heart attack. For maintaining low cholesterol, a diet full of fruits and fiber and low in fat, is effective. A diet should be low in saturated fat, higher in monounsaturated fats and foods rich in Omega 3 , thus raising the levels of good cholesterol and lowering bad cholesterol.

A significant portion of the adult population in the USA has cholesterol levels of 200 to 239 mg/dL, which are classified as borderline high-risk. It is also dangerous if the HDL level is below 40 mg/dL. If the HDL cholesterol count is high and the LDL count is low, a cholesterol level of 200 to 239 mg/dL may not necessarily represent a borderline high risk. But pay attention if some dangerous factors appear, such as hypertension and diabetes, and make sure to have regular check ups to ensure suitable treatment of high cholesterol(http://www.mitamins.com/disease/High-Cholesterol.html).

A total cholesterol level of 240 or more is considerably high. With cholesterol levels this high, you are at greater risk for heart attack and stroke. At this level, a complete change in dietary habits as well as increase in heart-friendly exercise (such as swimming or walking) is essential. Cholesterol-lowering drugs are included in the the treatment of high cholesterol.

The American Dietetic Association suggests keeping a cholesterol-friendly diet by eating plenty of vegetables, fruits and wholegrain foods. Some other advice is to limit saturated fats by choosing lean cuts of meat, chicken without the skin and low-fat dairy products.Reduce the intake of fattening fast food and processed cakes, sweets and chips. Choose canola or olive oils, which are better for the heart, when cooking. In fish such as mackerel and salmon, nuts and avocadoes, you can also find some other helpful oils. Remember to limit dietary cholesterol(http://www.mitamins.com/disease/High-Cholesterol.html) from egg yollk and meat.

Cholesterol: Good or Bad?

August 8, 2010 · Posted in cholesterol · Comment 

Let’s get something straight from the on start; cholesterol is an essential compound in humans and for that matter in the entire animal kingdom.

The idea that the cholesterol molecule is ‘bad’ is just plain inaccurate. Animals use cholesterol as their building blocks for cell membranes and other structural components. Cholesterol is the basic structural building block for hormones and other molecules essential to humans.

What is Good and Bad Cholesterol?

In actuality there is only good cholesterol until there is an over accumulation of cholesterol in the artery cells and in the peripheral cells.

LDL (Low-Density Lipoprotein) cholesterol particles (notoriously called bad cholesterol) carry cholesterol from the liver to receptor sites on the endothelial and peripheral cells. From the receptor sites the cholesterol is then transported for cellular repair and construction.

HDL (High- Density Lipoprotein) cholesterol particles (commonly called good cholesterol) are the primary reverse transport system which carries away excess cholesterol from the artery and peripheral cells to its destination the liver. The excess returned cholesterol is then either converted by the liver into cholesterol bile acids or excreted into bile as free cholesterol, which is then sent to the colon.

Hence the Problem:

In the delivery of cholesterol there are three (3) pathways or routes to arterial vessels and peripheral cells.

1). Lipid absorption

2). Endogenous (produced by the liver).

3). Exogenous (food intake).

The over accumulation of cholesterol can occur in all three (3) pathways resulting in atheroselerosis in the artery cells. The LDL delivery system from the liver presents the biggest threat for cholesterol buildup. Free radicals found in the bloodstream attack and oxidize the LDL cholesterol and chemically change it so that the receptor sites on the artery cell walls can no longer recognize the LDL, so it is rejected. Hence come the Macrophages, scavenger cells from our immune system which also have receptor sites. The Macrophages recognize that the LDL oxidized cholesterol at the endothelial artery lining. This is where the problem begins with cholesterol. Since the source of macrophages in the blood are for the most part iron and copper, which in turn act as a catalyst taking what is hydrogen peroxide and converting it into a potent hydroxyl radical.

Chaos Factor:

Macrophages analysis the oxidized cholesterol molecule (OXY-LDL) as an enemy or an invader and treat the oxidized cholesterol as if it were bacteria. The macrophages envelop the oxidized cholesterol particle through a process called Phagocytesis. Ultimately the particle is sent back further into the arterial wall or the cholesterol particle appears as a fused fatty nodule on the wall of the artery. Eventually other protectors in our immune system add to the fight and the whole cholesterol particle becomes a foamy cell. Sometimes oxidized LDL in small quantities can be disposed of in the artery by absorption or by breaking down the small nodule. Usually the buildup is too large to be broken down entirely and in fact the buildup continues unabated. This buildup leads to calcification, which invariably produces a bulge in the wall of the artery. If the extended nodule continues to grow, the flow of blood to and from the heart will be dangerously challenged and may result in blockage which can lead to such conditions as coronary arteries and carotid or vertebral arteries leading to the brain.

It has been established through research in patient studies that there are two (2) ways that oxidized LDL cholesterol can be formed.

1). Membrane damage of LDL fatty acids by metal ions (mostly iron in the blood).

2). Enzymatic damage unrelated or independent to metal ions

The researchers concluded that there are two (2) forms of oxidized LDL cholesterol.

1). OXY-LDL is a marker for coronary atheroselerosis.

2). MDA-Modified LDL a marker for artery plaque creation.

Antioxidants to the Rescue:

It is important that cholesterol is transported through the blood freely and unobstructed. The antioxidant level of the blood needs to be sufficiently high to abate free radicals before they attack the LDL particle. Additionally fat-soluble antioxidant levels of the LDL particle need to be high enough to thwart the oxidation of fatty acids (Phosholipids). Water-soluble antioxidants are important in the prevention of formation of oxidizes cholesterol in LDL particles and in blood in general.

Some key antioxidants are vitamins A, C, and E. others include green tea, bilberry, rosemary, lutein, and N-acetyl cysteine. Taking a regimented dose of antioxidant supplements has an important role in reducing the damaging effects of lipid oxidation.

Conclusion:

Our body was created perfectly without flaw, only when outside and foreign elements are introduced do we initiate a disease or an imbalance. Cholesterol in its purest form is harmless and essential to our bodily functions. Without the proper amounts of antioxidants in our blood, oxidation of LDL can occur in the blood and on the artery wall and lead to the formation of altherosclerosis. Supplementation of essential antioxidants is critical in an overall healthy body. Natural health products are the purest forms of supplementation.

Making Sense of Cholesterol Ratios, Lipid Profiles and Your Heart Disease Risk Scores

July 23, 2010 · Posted in cholesterol · Comment 

It’s very possible your MD orders lab work and you have no idea what or why you’re having blood drawn. Well, let’s clear up the confusion when it comes to your cholesterol labs.

The terms “lipid panel”, “lipid profile”, and “lipoprotein profile” are used interchangeably to order the same set of labs. To make reading this easier, I’m going to use “lipid profile” from here on out.

“Lipid” is simply a medical term for “fat”. A lipid profile measures fatty substances in your blood. Cholesterol is one type of fat.

When you eat food containing cholesterol or when your body produces cholesterol and releases it into your bloodstream, the cholesterol will attach to a protein. This package of cholesterol plus a protein is called a lipoprotein (lipid or fat plus protein). A lipid profile measures lipoprotein levels in your blood.

Lipid profiles include five components:

LDL – “bad” cholesterol
LDL (low-density lipoprotein) cholesterol carries mostly cholesterol, some protein, and minimal triglycerides throughout your circulation. LDL should be less than 130 mg/dL, ideally less than 100 mg/dL.

VLDL – “bad” cholesterol
VLDL (very low-density lipoprotein) cholesterol contains minimal protein and mainly transports triglycerides. VLDL should be less than 40 mg/dL.

Triglycerides
Triglycerides are a type of fat in the blood, not a type of cholesterol. Triglycerides are frequently used to estimate VLDL (“bad”) cholesterol. Here’s the calculation: triglycerides divided by 5 equals VLDL cholesterol. Triglycerides should be less than 200 mg/dL, ideally less than 150 mg/dL.

HDL – “good” cholesterol
HDL (high-density lipoprotein) cholesterol removes cholesterol from your bloodstream and carries it back to the liver. I like to think of HDL as a vacuum cleaner, picking up cholesterol LDL leaves behind in your arteries, the more HDL the better. HDL should be greater than 40 mg/dL, ideally greater than 60 mg/dL.

Total cholesterol
Cholesterol is essential to bodily functions, such as building cells and producing hormones. However, too much cholesterol will build up on artery walls, form a plaque, and potentially “plug” the artery resulting in a heart attack or stroke. Total cholesterol is calculated from the above components (Total cholesterol = HDL + LDL + VLDL). Total cholesterol should be less than 200 mg/dL.

Do you see how if you only know your total cholesterol, you only have one piece of the lipid profile?

Now, sometimes your results will include ratios or a risk score. Here’s an explanation of what those numbers mean.

Risk Score
A risk score is based on you lipid profile results, sex, age, family history, and various other risk factors. If you have a high risk score for heart disease, it’s best to speak with your MD to evaluate your risk score.

Cholesterol:HDL Ratio
You want a low ratio of cholesterol to HDL. A ratio lower than 4.5 is good, but 2 or 3 is best. You can calculate your cholesterol to HDL ratio by dividing total cholesterol by HDL. For example, your total cholesterol is 195 and your HDL is 55. 195 divided by 55 equals a ratio of 3.5.

It’s actually not your total cholesterol that has the greatest impact on your heart disease risk. The ratio of total cholesterol to HDL is a critical factor. If your total cholesterol is less than 200, but your ratio is 5, you are still at increased risk for developing heart disease.

LDL:HDL Ratio
This ratio compares the amount of bad (LDL) cholesterol to your good (HDL) cholesterol levels. You want a ratio less than 3.5, ideally less than 2.5. To calculate your ratio, divide LDL by HDL. For example, your HDL is 55 and LDL is 100. 100 divided by 55 equals a ratio of 1.8.

Triglyceride:HDL Ratio
A low ratio of triglycerides to HDL is best, ideally less than 2. To calculate your triglyceride to HDL ratio, divide your triglycerides by your HDL. For example, your triglyceride level is 200 and your HDL is 55. 200 divided by 55 equals a ratio of 3.6.

Lipid profiles are commonly ordered to assess your heart disease risk. Your doctor or dietitian will use the results to determine the best treatment to reduce your risk.

A lipid profile is beneficial, because you know your “good” cholesterol level and “bad” cholesterol levels. The interventions that work best to raise HDL and lower LDL differ, so knowing all your numbers helps you make the most effective changes.

You’re probably wondering why a lipid profile isn’t always ordered versus simply checking your total cholesterol (and possibly HDL). Cost and time always play a part and if your risk for heart disease is low, then a quick and less expensive screening makes sense. If you are at increased risk, a more complete assessment (lipid profile) may be more appropriate. Everyone’s situation is unique, so it’s best to discuss what’s right for you with your MD.

Learn About a Diet to Lower Cholesterol

July 11, 2010 · Posted in cholesterol · Comment 

Cholesterol is one of the major substances that cause heart attacks, high blood cholesterol levels, and weight problems. Despite its “bad guy image,” this waxy, fat-like substances made in the body by the person’s own liver serves a number of vital functions unknown to many.

Basically, there are two types of cholesterol: the Low-Density Lipoprotein (LDL) and the High-Density Lipoprotein (HDL). The former refers to the bad type of cholesterol that is known to clog the person’s blood vessels, thus, increasing the risk for a heart attack or a heart disease. Studies show that a diet that is high in saturated fat is a main dietary cause of a raised LDL cholesterol level. The latter, on the other hand, is the good type of cholesterol that helps clear LDL cholesterol out of the blood stream, thus, reducing the risk for any heart illness. Researches have shown that a diet rich in fruit and vegetables along with average levels of omega-3 from fish oil greatly helps raise HDL cholesterol levels.

Although diet is the major reason for having high cholesterol levels, experts agree that factors such as genetics, lack of exercise or regular physical activity, obesity, unhealthy lifestyle such as excessive drinking and smoking, hormones, and varying high and low cholesterol levels can trigger the sudden increase of cholesterol levels in the body.

GETTING STARTED

Indeed, cholesterol is a growing problem in the health of many people in the world. Experts say that people over 20 years of age should be more concerned about their cholesterol levels; thus, they should start doing everything they can to lower LDL cholesterol. Although it is quite hard to stick to the needed requirements and regiments to combat the growing problem, experts say that it can be controlled with the proper diet to lower cholesterol.

Studies show that a good diet to lower cholesterol can reduce a person’s risk for heart diseases while getting rid of bad fats because this diet to emphasizes on eating heart-healthy foods. But, aside from using the proper and proven low cholesterol diets available today, the most important thing is that knowing and taking in the right foods and effective cholesterol formulas to assist in lowering cholesterol levels.

Experts say that a diet to lower cholesterol includes good foods like grains-especially whole grain products and cereals-fish rich in omega3 such as salmon and tune, a variety of fruits and leafy vegetables, nuts, juices, and the like. Here are other effective means of lowering cholesterol level through diet:

1. Make sure that you visit your attending physician first before trying out any low cholesterol diets so he/she could administer the proper examinations and access your general health status.

2. You can lower your cholesterol levels by replacing saturated fat with polyunsaturated fat in meat, chicken, and whole milk products.

3. Refrain from eating refined carbohydrates contained by bakery products, pastas, and sugary or sugar-added foods.

4. When eating out, makes sure that you ask the waiter to make serving substitutions like steamed or boiled food preparations. If possible, also pick lean meat, fish, or skinless chicken that is broiled, baked, grilled, steamed, or poached instead of being fried and ask for lots of vegetable side dishes and fresh fruit desserts.

5. Cutting down on eggs, margarine, or butter out of your daily diet.

6. Use natural-based oils such as vegetable, corn, and olive oils when cooking instead of the usual cooking oil.

7. Load up on a lot of garlic when you’re preparing dishes because it contains substances that help lower HDL cholesterol.

8. Take in high quality daily vitamin mineral supplements like Vitamin E to improve blood circulation, and Vitamin C and vitamin B3 to lower your high cholesterol levels.

Fight High Cholesterol With Vitamins And Over The Counter Products

July 6, 2010 · Posted in cholesterol · Comment 

More that a million Americans die of heart disease each year. One of the major causes of this heart disease the high cholesterol levels in the blood.


Cholesterol plays a central role in many biochemical processes, but is best known for the association of cardiovascular disease with high levels of

cholesterol in the blood.


Konrad Bloch and Feodor Lynen shared the Nobel Prize in Physiology or Medicine in 1964 for their discoveries concerning the mechanism and regulation of the cholesterol and fatty acid metabolism.


Cholesterol is a sterol (a combination steroid and alcohol) and a lipid found in the cell membranes of all body tissues. It is transported in the blood plasma of all animals. The average amount of blood cholesterol varies with age, typically rising gradually until one is about 60 years old.


In recent years, the somewhat imprecise term “bad cholesterol” has been used to refer to LDL (low density lipoprotein) which, according to the lipid hypothesis, is thought to have harmful actions, and “good cholesterol” to refer to HDL (high-density lipoprotein), thought to have beneficial actions.


The American Heart Association provides a set of guidelines for total blood cholesterol levels and risk for heart disease. The desirable LDL level is considered to be less than 100 mg/dl. However the 1987 report of National Cholesterol Education Program suggest the total blood cholesterol level should be less than 200 mg/dl normal blood cholesterol, if the cholesterol level is between 200 and 239 mg/dl it is considered borderline-high, and higher than 240 mg/dl is considered high cholesterol level.


Conditions with elevated concentrations of oxidized LDL particles are associated with fatty deposits forming on the walls of arteries, a condition known as Arteriosclerosis, which is considered the principal cause of coronary heart disease and other forms of cardiovascular disease.


In contrast, however, if LDL particle number is low and a large percentage of the HDL particles are high, then fatty deposits forming on the walls of the arteries are usually low, and can even be negative, for any given total cholesterol concentration.


Cholesterol is found in animal fats: all food containing animal fats contains cholesterol. Plants have trace amounts of cholesterol, so even a Vegan diet, which includes no animal foods, has traces of cholesterol.


Cholesterol is not necessarily dietary in origin, it can be turned into cholesterol by the liver from unburned food metabolites. The liver converts unburned food metabolites into very low density lipoproteins (VLDL) and secretes them into plasma where they are converted to low-density lipoprotein LDL) particles and fatty acids, which can affect other body cells. There appear to be seasonal variations in cholesterol levels in humans because of the unburned food metabolites the amount of cholesterol is higher in winter.


Cholesterol is required to build and maintain cell membranes; it regulates membrane fluidity over a wider range of temperatures. Cholesterol also aids in the manufacture of bile (which stored in the gallbladder and helps digest fats), and is also important for the metabolism of fat-soluble vitamins, including vitamins A, D, E and K.


Cardiologists suggest that the public need to change its diet. To reduce cholesterol levels by lowering saturated animal fats and increasing polyunsaturated fats. Lowering cholesterol is a good start but it is far from all that is needed.


Common Vitamins and over the counter products can help with High Cholesterol such as Vitamin C, Lecithin, Pectin, Garlic, EPA, Niacin and Phytosterols.


Vitamin C has been shown to combat the development of cholesterol deposits in the arteries. Within a few hours after receiving vitamin C patients showed a sharp decline in the cholesterol levels of the blood.


Lecithin has the potential to protect against fat clogged arteries when take daily.


Pectin limits the amount of cholesterol the body can absorb. High pectin count in apples may be why “One a day keeps the doctor away”.


Garlic counteract the usual result of high fats in the diet and to help reduce high blood pressure.


Studies of the Greenland Eskimos lack of heart attacks have show that Eico-Sapentaenoic Acid (EPA) lowers blood cholesterol considerably, even more than polyunsaturated fat does. It also triggers a major drop in triglycerides. Salmon Oil is one of the best known sources of natural EPA.


Niacin is the closest thing available to a perfect treatment that corrects most causes of coronary heart disease. Niacin blocks the release of fatty acids from fat cells. Niacin plays a critical role in energy production, gene expression, and hormone synthesis. You cannot live without it. Niacin also tends to shift LDL particle distribution to larger particle size and improve HDL functioning. The intake of 3 grams Niacin for as little as two weeks can reduce serum cholesterol by 26 percent.


Phytosterols is found in flax seed and peanuts, which are suggested to help lower serum cholesterol.

Get Information About Cholesterol

July 3, 2010 · Posted in cholesterol · Comment 

Cholesterol is a fatty substance (a lipid) that is an important part of the outer lining (membrane) of cells in the body of animals. Cholesterol is also found in the blood circulation of humans. The cholesterol in a person’s blood originates from two major sources; dietary intake and liver production. Dietary cholesterol comes mainly from meat, poultry, fish, and dairy products. Organ meats, such as liver, are especially high in cholesterol content, while foods of plant origin contain no cholesterol.

Blood cholesterol level is affected by the diet, since cholesterol is present in certain foods and is manufactured in the body from digested fats. High levels of cholesterol in the blood are associated with hardened arteries (known as atherosclerosis), coronary artery disease (heart attack), and stroke.

There are many types of cholesterol. LDL or Low-density lipoprotein is the “bad” cholesterol, as it blocks the arteries. HDL or High-density lipoprotein is the “good” cholesterol, as it protects the arteries from clogging.

Diets should contain less than 30% calories from fat, less than 8% from saturated fat, and enriched in marine or plant omega-3 fatty acids. Avoid high saturated fats, like diary fats (ice cream, butter) and palm and coconut oils. Limit high cholesterol foods, like eggs and organ meats (liver). Eat higher fiber foods, fruit and vegetables. Eat more fish and skinless chicken breasts. Avoid fried foods and frying which soaks up the fat . Choose low fat and non-fat dairy products, avoid hard margarines which have trans-fatty acids, and try to use products made from plants instead.

Cholesterol really assists the system by creating original cells, aiding in the output of hormones, and insulating the numerous nerves that operate throughout the system. High cholesterol rates are alarmingly growing. Cholesterol may be accounted for higher blood force and coronary eye diseases but not all of these oily substances are detrimental. There are the terrible and better cholesterol. The better cholesterol aids in bile salts output and vitamin D formations. In fact, cholesterol portrays a character of balancing hormones especially among women. Health professionals are trying urgently to offer extreme solutions to the matter.

High blood cholesterol is one of the major risk factors for coronary heart disease, and it is a risk factor you can modify. Knowing your total cholesterol, HDL, LDL, and triglyceride levels is an important first step in determining your risk for heart disease. Left undiagnosed or untreated, a high blood cholesterol level, as well as other coronary risk factors, can lead to possible serious cardiovascular problems in the future.

Get physical, do regular physical activities and exercises more often. The wonders of exercise are indeed very essential in lowering high cholesterol levels. Doing regular physical activities can also help raise the good cholesterol levels and lose weight as well. There’s really no need for high-intensity workouts, regular brisk walking or jogging can help the body boost HDL cholesterol and also beneficial for the heart.

Medications for cholesterol are most often long-term medications. They have to be taken everyday, often for the rest of your life. Drugs that are most often prescribed are the statins. Statins help the liver remove LDL cholesterol, and reduce production of cholesterol.

How High Should Your Cholesterol Levels Be?

July 1, 2010 · Posted in cholesterol · Comment 

A 2007 report from the Women’s Health Study showed that high levels of cholesterol, even in healthy women, was a risk factor that increased a woman’s chances of having a stroke. Other studies have shown a link between high levels of cholesterol and Alzheimer’s disease. And the media has been warning us for years to cut down our intake of cholesterol because high cholesterol leads to hardening of the arteries. But what is cholesterol and why is it even it our bodies?

Cholesterol is a soft, waxy, fat-like substance that is made by the body. It is in all of your cells and can be found in all parts of the body including your skin, blood vessels, muscles, and so on. Since your body actively creates cholesterol, we can assume that having cholesterol in your body is not necessarily bad. In fact, you couldn’t eliminate all the cholesterol in your body if you tried.

Cholesterol is important for the body. The cells use cholesterol as a building block in creating its protective membrane. Studies have indicated that “good” HDL cholesterol protects against heart disease and stroke even if “bad” LDL cholesterol levels are high. Good cholesterol helps to prevent dangerous breakaway blood clots – which can be caused by sitting in a cramped position for too long. Cholesterol also helps to manufacture vitamin D in the body from the sun. And there is much more good that cholesterol does for the body.

There is also a second source of cholesterol. Dietary cholesterol comes form the foods that we eat. It can be only be found in animal foods and eating it raises the bad cholesterol level in your own body. There have been many studies over the years that correlate a high intake of dietary cholesterol to coronary heart disease. In other words, the more high cholesterol foods we eat, the greater our chance of developing heart disease or a stroke.

High density lipoprotein (HDL), the good cholesterol, is a form of cholesterol that circulates in the bloodstream. One of its jobs is to remove excess cholesterol from the body’s tissues and transport it to the liver where it will be excreted from the body. This process of “taking out the garbage” or cleansing the bloodstream is why HDL is a called good cholesterol and also why it’s good for your body to have a relatively high HDL level. Some researchers say that an HDL of 60 milligrams per deciliter (mg/dl) or greater is good and will protect you against hardening of the arteries and lower your risk of getting heart disease.

Conversely, a low level of HDL, such as less then 40 mg/dl, has a negative effect. Many studies indicate that a low level of HDL combined with a high level of LDL seems to be a precursor of heart disease

You can control your cholesterol. The total amount of cholesterol in your body at any point in time is a function of how fast your HDL and liver can cleanse your system of it’s existing cholesterol combined with the amount of dietary cholesterol that you’ve eaten during recent hours.

Controlling the amount of cholesterol that you allow into your body is a huge part of your lifestyle that you can modify to decrease your chances of heart disease or stroke. According to the American Heart Association, if you eat less then 300 milligrams of cholesterol a day, you can significantly reduce your cholesterol levels. By paying greater attention to the foods you eat, you can help to assure yourself of a long and healthy life.
