The Malign Effects of High Cholesterol

October 15, 2010 · Posted in cholesterol · Comment 

Statistics reveal that around 20 percent of people in the United States have abnormally high cholesterol. High cholesterol is a major factor of risk in heart disease and therefore it needs to be reduced to normal levels in order to maintain the health of the organism. In some people, high cholesterol levels can be lowered through the means of a healthy diet and proper physical exercise. However, people with genetic predispositions to heart disease and cholesterol accumulation sometimes also require medications for lowering blood cholesterol levels. Some people have high cholesterol levels due to liver hyperactivity or other internal dysfunctions. For this category of people, appropriate diet, frequent physical exercise and lifestyle improvements aren’t sufficient in normalizing blood cholesterol values.

There are many factors that facilitate the accumulation of cholesterol inside the bloodstream. Unhealthy diet, sedentary lifestyle, smoking and alcohol abuse all contribute to cholesterol accumulation in the organism. However, age, gender and genetic heritage are also major factors that determine either overproduction or inappropriate elimination of blood cholesterol.

High cholesterol levels are usually characteristic to people with ages over 50. Women generally have lower blood cholesterol levels than men. However, post-menopausal women have higher blood cholesterol levels than young men. Genetic heritage also affects blood cholesterol levels and people with a family history of cardio-vascular diseases usually have high cholesterol and are very exposed to developing heart disease.

Cholesterol is needed inside the organism in very small quantities. In excess, the substance can cause a lot of damage to arteries, tissues and body organs, perturbing normal blood circulation. By clogging the coronary arteries, cholesterol increases the risk of heart disease. Cholesterol is a viscous substance produced by the liver. This substance has a very important role in synthesizing vitamin D. Cholesterol is also required for producing hormones (testosterone and estrogen) and bile salts that contribute to the digestion of fat.

The best thing to do when you have high cholesterol is to keep a good diet. Although diet alone can’t always overcome cholesterol problems, it can considerably reduce “bad cholesterol”. “Bad cholesterol” (low-density lipoprotein) is very harmful for the body and it is the major factor of risk in heart disease. By following a diet rich in complex carbohydrates, natural fibers and unsaturated fat you can normalize blood cholesterol levels. In order to reduce blood cholesterol levels, you should avoid foods that are rich in saturated fat (animal products) and include more vegetables and fruits in your diet. Fresh fruits are rich in vitamins, minerals and fibers that can help in decongesting the arteries filled with cholesterol deposits.

You should avoid smoking and alcohol, as they are known to facilitate the accumulation of cholesterol inside the body. People with high cholesterol levels should exercise regularly and lose extra pounds, as obesity is also a factor of risk in heart disease. High cholesterol levels are reversible and if nothing seems to be working for you, there are medical treatments that can improve your condition.

Food to Lower Your Cholesterol

August 15, 2010 · Posted in cholesterol · Comment 

High cholesterol levels are slowly killing off the population. The increasing prevalence and risk of hypertension and heart disease in Americans are ringing the alarm bells in the country’s health sector. Health officials are desperately trying to find ways to combat the rise and make people aware of the eating lifestyle and exercise lifestyle that they are imbibing.

The truth about cholesterol

Although cholesterol is mainly the culprit in the increase in high blood pressure in the body, not all cholesterol that we take in is essentially bad. In fact, small amounts of cholesterol is being used by the body in the production of bile salts and in the transformation of Vitamin D. Cholesterol also plays a role in the balancing of hormones especially in women.

There are two kinds of cholesterol, the good and the bad as the lay people will like to clal them. The bad cholesterol or the LDL is the kind that is often found in saturated fats and trans fatty acids. These are taken into the body through foods that are pre-packed and prepared such as potato chips, canned goods, etc. LDL cholesterol adheres to the walls of the arteries. High levels of LDL can form plaques in the arterial walls that may eventually cause clogging in the passageway of the blood. This slows down the blood flow, which in turn makes it hard for the heart to pump. This scenario describes the initial stages of hypertension and coronary heart problems.

What to eat

The good cholesterol HDL on the other hand lower the levels of LDL in the body by helping transport the LDL to the liver where it is excreted. HDL cholesterol can be found in fishes as well as in nuts.

Other foods that can lower the cholesterol levels are fruits and vegetables. These foods do not contain that much cholesterol so whatever you have, you will not be adding to its levels.

Another great thing about veggies and fruits is the fact that they are great sources of fibers that the body also need to combat the increase in LDL cholesterol. Berries, fruits that are citrus and carrots are just some of the fruits that you can count on.  Another food that can dramatically reduce the levels of cholesterol in the body is the soya. Fiber-rich food, soya as well as almonds and plant sterols figure in a landmark study conducted by University of Toronto that reduced the cholesterol levels of the participants by as much as 20 percent. Eating oats, olive oil and barley are also great ways to lower LDL.

Another great source of cholesterol are foods that are really oily. To lower one’s LDL, one must consciously avoid foods that are deep-fried. If you have to eat fried foods, make sure that the oil that you use is made out of vegetable.

Never use butter as this is rich in saturated fats. Instead, use margarine as a substitute. Try to also steam, braise, boil or bake your food. You will find that they are tastier and healthier.

Not just the food

There are many factors that contribute to the rise of cholesterol levels in the body. In addition to one’s eating lifestyle, there is the age, the gender, the family history and of course the amount of physical activity that the person does.

Exercise is fairly important in keeping LDL cholesterol at bay. What is more, it strengthens the body’s resistance as well as improves blood circulation.

Cholesterol is a Major Building Block From Which Cell Walls are Made

May 11, 2010 · Posted in cholesterol · Comment 

Cholesterol is manufactured in the liver for normal body functions, including the production of hormones, bile acid, and vitamin D. Cholesterol is required to build and maintain cell membranes; it regulates membrane fluidity over a wide range of temperatures. Cholesterol is a building block in many important cell components especially the cell membrane and is the starting point for several hormones. About one third to one fourth of the total amount of cholesterol is HDL cholesterol.

HDL cholesterol is called the “good cholesterol” because HDL cholesterol particles prevent atherosclerosis by extracting cholesterol from the artery walls and disposing of them through the liver. LDL cholesterol is called “bad” cholesterol, because elevated levels of LDL cholesterol are associated with an increased risk of coronary heart disease. Of particular interest is the finding that a high ratio of triglycerides to HDL cholesterol is a powerful risk factor for a major cardiac event even when LDL cholesterol levels are normal. It is now clear that any food that lowers LDL cholesterol or raises HDL cholesterol is what we should be looking for.

Most cholesterol is LDL cholesterol, and this is the kind that’s most likely to clog the blood vessels, keeping blood from flowing through the body the way it should. Some cholesterol is normally present in plasma (the liquid part of blood) attached to proteins (lipoproteins) that transport it and other fat molecules around the body. When too much cholesterol is present, plaque (a thick, hard deposit) mayform in the body’s arteries narrowing the space for blood to flow to the heart. LDL cholesterol is more likely to clog blood vessels because it carries the cholesterol away from the liver into the bloodstream, where it can stick to the blood vessels.

Cholesterol is so important that the body produces its own cholesterol. Cholesterol in food and cholesterol in the blood are distinct entities, and they are often confused. You need some cholesterol to help your brain, skin, and other organs grow and do their jobs in the body. When you have too much cholesterol, it can be dangerous to your health.

Cholesterol levels naturally rise as men and women age. Many factors can contribute to high cholesterol, but the good news is there are things you can do to control them. Try to eat less saturated fat, limit the amount of trans fat, and limit cholesterol (check food labels if you’re not sure how much of these particular foods contain). Instead of eggs, try just egg whites or cholesterol-free commercial egg substitutes.

Changing from an unhealthy diet to a healthy diet can reduce a cholesterol level. If you find your blood cholesterol level is too high you can generally reduce it by following the advice of a trained dietitian, which generally means eating less fat and more fibre, and especially soluble fibre. Major dietary sources of cholesterol include egg yolks, beef, poultry, and shrimp. Here are some helpful tips you can try:Eat a diet that contains many low-cholesterol foods: fruits, veggies, whole grains (like breads and cereals), legumes (beans), and fish.

Eating a lot of fats and not getting enough exercise can cause cholesterol levels to rise. It’s also a good idea to get plenty of exercise to help control the amount of cholesterol in your blood and keep your heart and blood vessels healthy. Major health agencies such as the Centers for Disease Control and Prevention and the American College of Sports Medicine (ACSM) recommend that for good health and to reduce risk of chronic disease, adult Americans should participate in moderate-intensity aerobic (or cardio) exercise (such as brisk walking) for at least 30 minutes on 5 or more days of the week or vigorous-intensity cardio at least 3 days of the week.

The Hypercet Cholesterol Formula can help support and maintain your healthy cholesterol levels already within the normal range.

Is There Good And Bad Cholesterol?

February 9, 2010 · Posted in cholesterol · Comment 

Many classify cholesterol as good and bad. This is not true. Cholesterol is simply cholesterol. When thinking of good and bad, many are referring to HDLs and LDLs. HDL refers to high density lipoprotein while LDL refers to low density lipoprotein. Lipoproteins are merely cholesterol carriers. Lipoproteins are part lipid (fats) and part protein. The reason for this structure is proteins are soluble in water whereas fats are insoluble in water. The protein portion is used to transport the lipids through the blood. Since blood is comprised mostly of water, the lipid portion would not travel without the protein portion.

HDLs consist of about half protein and half lipid; whereas LDLs are about a quarter protein and three quarters lipid. The function of the HDL is to bring cholesterol to the liver for recycling or elimination. Low density lipoproteins transport cholesterol to the rest of the body for building tissues.

Cholesterol by chemical structure is an alcohol, because of the hydroxyl group (OH). Remember, ethanol (found in alcoholic beverages and gasoline) is also an alcohol but a much smaller alcohol. Cholesterol contains a four ring region that is characteristic of all steroid hormones (estrogen and testosterone). However, combination of the steroid ring structure and the hydroxyl group classify cholesterol as a sterol.

Cholesterol has many functions. Cholesterol is the precursor to all steroid hormones produced in the body. This includes mineralcorticoids, glucocorticoids, and the sex hormones.

Cholesterol is found in every cell. Cholesterol regulates the cell membranes fluidity. This prevents the cell from becoming too rigid or too fluid. Cholesterol helps keep the cell membranes intact. Cholesterol helps to build strong bones and muscles, and maintains libido and fertility. Cholesterol assists in regulating the blood sugar. Cholesterol helps to protect against infectious disease and repairs damaged tissue. Cholesterol is required to form vitamin D.

Cholesterol is a component of lipid rafts, this helps to secure proteins involved in cell signaling. When sleeping at night, our brain synthesizes cholesterol to benefit our mood and increase our memory. Cholesterol supports the nervous system, in which cholesterol is a vital component of the myelin sheath. The myelin sheath allows neurons to conduct impulses with each other. Cholesterol has been found to be the rate limiting factor found in the formation of synapses, this formation is necessary for learning and the formation of memories.

Cholesterol is used by the liver to synthesize bile acids. The liver makes about two grams of cholesterol daily. However, under stressful conditions the production of cholesterol increases to produce more adrenal and stress hormones. Bile acids are secreted into the small intestine to emulsify fats, aiding in digestion.

Many studies cannot correlate eating foods containing cholesterol with an increase in blood cholesterol. Eating a diet high in meat and fat does not necessarily indicate heart disease. For example, the Eskimos live on a diet rich in meat and fat. The Eskimos have low cholesterol levels. Many populations that consume a high percentage of animal fats have less heart disease. Why? Animal fats are more resistant to oxidative damage. Many do not realize that cholesterol plaques are often there to protect a damaged artery. Many need to understand that a clogged artery is better than a ruptured one. Although elevated cholesterol levels are associated with heart disease, cholesterol may not be the cause.

If cholesterol is not the cause of heart disease, what are the causes? Many factors may contribute to cardiovascular disease. Heart disease can be associated with deficiencies in a few minerals (copper, zinc, magnesium). Toxicity in calcium can assist in hardening of the artery walls. Increased homocysteine (amino acid found in vitamins b6 and folic acid) levels are a factor in heart disease. Deficiencies of vitamin C and the amino acid lysine cause decreased collagen synthesis. Also, hypothyroidism is associated with heart disease. Certain types of infections and inflammations are related to heart disease (dental infections). High blood pressure can lead to heart disease. Smoking, diabetes, obesity, caffeine, and a sedentary lifestyle increase the risk of heart disease. Finally, genetic factors play a part in heart disease. Any oxidative damage from vegetable oils contributes to heart disease. Hydrogenated fats found in margarine, dressings, fried foods contribute to heart disease. Hydrogenation produces trans-fatty acids. These are non-naturally occurring fatty acids that contribute to inflammation, one of the causes of heart disease.

Cholesterol has a bad reputation and many misunderstand. The truth to the importance of cholesterol is simply not widespread enough. Cholesterols role in heart disease cannot be linked. When understanding what may cause heart disease, total cholesterol is not as important as the ratio of HDLs to LDLs. This organic compound is essential for life as we know it.

What is High Cholesterol?

January 25, 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’s 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 centre for cholesterol. When we eat animal fats, the liver returns the cholesterol it can’t 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.

There are two types of cholesterol, good and bad, the difference between them is:
Low density lipoprotein (LDL) cholesterol – called the ‘bad’ cholesterol because it goes into the bloodstream and clogs up your arteries.
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:

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.
-Choose low or reduced fat milk, yoghurt and other dairy products or have ‘added calcium’ soy drinks.
-Choose lean meat (meat trimmed of fat or labeled as ‘heart smart’).
-Limit fatty meats, including sausages and salami, and choose leaner sandwich meats like turkey breast or cooked lean chicken.
-Have fish (fresh or canned) at least twice a week. Replace butter and dairy blends with polyunsaturated margarines.
-Include foods in your diet that are rich in soluble fiber and healthy fats, such as nuts, legumes and seeds.
-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

Plant sterols 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.
