What is Cholesterol?

Cholesterol is a waxy, fat-like substance that is found in all cells of the body. Your body needs some cholesterol to function and makes all the cholesterol it needs in order to keep you healthy. It is also present in some of the foods we eat. It is used to make hormones, Vitamin D, and substances that help you digest foods.

What is HDL and LDL Cholesterol?

Blood is a watery like substance and cholesterol is an oily one. As a result the two do not mix well together. So for it to travel in the bloodstream, cholesterol is carried in packages called lipoproteins. These packages are made of fat (lipo) on the inside and proteins on the outside. Two kinds of lipoproteins carry cholesterol throughout your body, High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL).

LDL Cholesterol (”Bad” Cholesterol)

High levels leads to a buildup of cholesterol in arteries, this is “bad” as it narrows/clogs them giving a greater chance of heart disease.

HDL Cholesterol (”Good” Cholesterol)

This carries cholesterol from other parts of your body back to your liver. The liver removes the cholesterol from your body. The higher your HDL cholesterol level, the lower your chance of getting heart disease.

Myths about Cholesterol

Below I have tried to clear up the misunderstandings that have occurred over this subject. Historically laymen, doctors and most scientists have been misled, as a result of systematically ignored or misquoted scientific data.

1. The only effective way to lower cholesterol is with drugs.

Truth: These drugs do not improve heart mortality or total mortality as their effect is only to lower cholesterol. In fact these drugs may be dangerous to your health and can shorten your life.

2. High blood cholesterol causes atherosclerosis

Truth: Many studies have shown that people with high blood cholesterol become just as atherosclerotic as people whose cholesterol is low.

3. Your body produces three to four times more cholesterol than you eat.

Truth: The production of cholesterol increases when you eat little cholesterol and decreases when you eat much. This explains why the “prudent” diet cannot lower cholesterol more than on average by a few per cent.

4. The Statins prevent heart disease by lowering Cholesterol.

Truth: These drugs do help prevent cardio-vascular disease, but this is due to other mechanisms than cholesterol-lowering. Unfortunately, they also stimulate cancer in rodents, disturb the functions of the muscles, the heart and the brain and pregnant women taking Statins may give birth to children with malformations more severe than those seen after thalidomide.

5. Cholesterol is a deadly poison.

Truth: Cholesterol is a substance vital to the cells of all mammals.
All cholesterol is not bad, but mental stress, physical activity and change of body weight may influence the level of blood cholesterol. High cholesterol is not dangerous by itself, but may reflect an unhealthy condition, or it may be totally innocent.

With all the talks of obesity and America’s race for thin bodies, cholesterol has suffered a beating. It is even one of the main figures in the development of hypertension, that contribute much to coronary heart disease. Often seen as the culprit in “fattening” America, cholesterol has become a food taboo, something that must be avoided at all costs.

What people do not know though is that there are two kinds of cholesterol and one kind is actually beneficial to the body. In fact, it is one of the essential substances that our bodies need to maintain balance.

What is cholesterol?

Cholesterol is a substance that can be found in fats or in lipids. Lipids are important because it is used to form cell membrane, used to balance hormones and help in other bodily functions. Too much cholesterol though tends to clog the bloodstream, eventually leading to heart disease. And because cholesterol cannot easily dissolved, only transported, the risk of build-up is great. As mentioned earlier, there two kinds of cholesterol, the LDL and the HDL cholesterol.

The bad cholesterol

The LDL cholesterol is frequently referred to as the “bad cholesterol” because too much of these can accumulate in the walls of the arteries and clog the blood stream that leads to the heart and the brain. This build up, called atherosclerosis, which can eventually lead to a heart attack or a stroke (brain attack) depending on where the arteries are leading to.

High LDL increases the risk for heart disease so it important that it is kept at normal range, which is below 100 mg/dL.

The good cholesterol

The HDL cholesterol on the other hand is referred to as the good cholesterol as high levels seem to protect a person from heart disease and hear attacks. According to some experts, instead of staying at the arteries like the LDL, HDL leaves the arteries and instead goes to the liver. In contrast with LDL levels, a low HDL increases the risk for heart attack. Levels of HDL should not be below 40 mg/dL for men and 50 mg/dL for women. Regular exercise has been found to increase the levels of HDL.

Cholesterol in food

Foods that come from animals contain cholesterol levels. Just how much depends on the kind of animal food. vegetables however do not contain any cholesterol.

In addition to the cholesterol that we get from food, the body is also capable of producing its own cholesterol. This creates a problem in overproduction since we also take in cholesterol through the foods that we eat. Average individuals or those who do not have any heart problems should only take in about 300 milligrams.

For people who are already at risk for coronary heart disease and heart attack, physicians recommend the reduction in the intake of cholesterol. They should only take in less than 200 milligrams. Everyone is also advised to keep their consumption of saturated fats to a minimum, as these can significantly help in lowering the risk for heart disease.

People, who have severe high blood pressure, are however advised to take in no more than six ounces of lean meat and fish daily. They should also choose the products thatv they buy and ensure that they are fat free or low-fat.

Many people experience occasional heartburn. Prevention of heartburn may be achieved by avoiding certain foods, beverages or making certain lifestyle changes. Heartburn treatment, when necessary, can provide relief from the burning sensation. Those who experience heartburn symptoms once or more per week may want to have their symptoms evaluated by their physician. Sometimes frequent heartburn is a symptom of a more serious health problem.

Prevention of heartburn in some cases may be achieved by avoiding spicy or highly acidic foods like tomatoes and tomato products. Fried foods can also lead to heartburn. Eating too quickly or too much at once can lead to heartburn. In cases of heartburn caused by eating too much or the wrong foods, an over the counter antacid is usually an effective heartburn treatment. Sometimes it is necessary to keep a food diary or at least make a mental note of when the heartburn symptoms occur. Some people have found that prevention of heartburn is possible, if they are able to identify the foods that trigger the symptoms.

Heartburn symptoms occur when stomach acid leaks up into the lower esophagus causing a burning or warm sensation in the back of the throat or at the top of the stomach. An overly full stomach will be more likely to “spew” the stomach acid up. Thus, eating smaller meals is often effective for the prevention of heartburn.

The stomach has a tendency to produce more acid during stressful times. In fact, many people notice their first episode of heartburn after a particularly stressful period in their lives. Those who suffer from anxiety are more likely to experience heartburn. And in these people, it is often necessary to treat the anxiety in order to achieve prevention of heartburn. Relaxation techniques are an effective heartburn treatment for some. Deep breathing, meditation or just eating in a peaceful relaxing environment may be effective for the prevention of heartburn. Eating in front of the television is a common habit, but we have a tendency to overeat and/or eat too quickly when we are not focusing on our dinner. Thus, making changes in when and where you eat may be effective for the prevention of heartburn.

Drinking coffee, carbonated beverages or alcohol leads to heartburn in some people, particularly on an empty stomach. Effective prevention of heartburn is achieved in some cases by either foregoing the morning cup of coffee or eating a bowl of cereal first. Our busy lifestyles mean that we often “grab” something to eat, gulp down a cup of coffee to get going and then find ourselves at the local convenience store searching for a heartburn treatment. Trying to slow down around mealtimes is often effective for the prevention of heartburn.

If you are a smoker, prevention of heartburn is another good reason to quit. Saliva is necessary both to properly digest food and to neutralize stomach acid. Smoking dries out the saliva in the mouth and throat and will lead to heartburn, eventually, in most people. It is a common misconception that smoking is relaxing. Nicotine is a stimulant. Stimulants create more stress and, as previously mentioned, stress leads to heartburn. Those who have stopped smoking have noted a decrease in the need for heartburn treatment.

In some cases, prevention of heartburn requires a prescription drug. There are several on the market. Your doctor can provide you with more information about them. Drugs like these are not intended for heartburn treatment, but for the prevention of heartburn. They are taken on a daily basis, not after heartburn symptoms occur. All have some side effects and should not be taken by certain people. Only you and your physician can decide if the frequency of your heartburn makes you a candidate for these drugs.

Effective prevention of heartburn has been achieved by many people in many different ways. There are herbal remedies that have proven effective for the prevention of heartburn for some people. Herbal remedies may have unwanted side effects, just like there prescription relatives. It is important to learn as much as you can about the herbs that you are considering, before you begin use. Natural does not always mean safe. Heartburn treatment using peppermint, fennel or other common food items is generally safe. But, remember your allergies and if you are pregnant or nursing, always check with your doctor.
