In this report,you will learn:
* What is cholesterol
* What it does
* What are healthy cholesterol levels

* What are the consequences of high cholesterol
* What can you do to lower your cholesterol
* What are the treatments options for cholesterol
What is cholesterol?
Cholesterol is a natural component of the internal environment of the body. It is a waxy molecule that is used in many bodily functions. For one, it is used in cellular membranes to help maintain their integrity. Also, cholesterol is instrumental in creating hormones specifically steroids and sex hormones. So, the body relies heavily on a normal level of cholesterol in the bloodstream.
Cholesterol is instrumental in turning sunlight into Vitamin D. Vitamin D works to increase calcium stores in the body. Calcium, as you know, is needed for strong bones and teeth.
How Does Cholesterol Affect the Body?
Cholesterol has three main components: Low-density lipoprotein (LDL), high-density lipoprotein (HDL) and triglycerides. Each serves a specific purpose.
Cholesterol moves along through the bloodstream from place to place conducting its business. Because it doesn’t dissolve and therefore can’t pass through membrane wall, it needs a carrier, namely the lipoproteins to help it get to the cells where it works.
Let’s look at LDL first. This is termed the “bad” cholesterol. If you have too much of it in your bloodstream your risk of certain diseases rises.
It is produced in the liver. Just like other lipoproteins, it is a carrier for cholesterol throughout the blood. Levels are kept low because it is a sticky lipoprotein. This means that it will adhere to arterial walls. The arteries become stiff, a condition known as atherosclerosis.
When there is too much LDL, it can form hard plaques inside the vessels. These plaques narrow the opening inside the vessels through which blood has to pass. The heart has to pump that much harder to get blood through. This may increase the blood pressure. Too much pressure can dislodge the plaques allowing them to travel leading to pulmonary embolus or stroke.
HDL cholesterol is termed “good” cholesterol. These lipid molecules transport cholesterol also. It can be thought of as a sweeper because it goes behind and cleans up what was done by the LDL cholesterol. It is important to have high levels of good cholesterol to counteract any affects of bad cholesterol in your body.
The cholesterol that is carried is excess cholesterol found in the bloodstream. The cholesterol is returned to the liver where it is slated for excretion from the body. This is good because it helps remove sticky LDL cholesterol from arterial walls reducing the buildup of life-threatening plaque deposits.
Triglycerides are another component of blood cholesterol. These are fats that are produced in the liver and also enter the body as fat from the foods that we eat. Like the other two components, it does not travel alone throughout the body. It combines with a protein and is referred to as VLDL (very low density lipoprotein). If high levels of LDL cholesterol are bad, then combining it with high levels of VLDL, your risk of stenotic vessels, heart attack and stroke increase.
Triglycerides provide energy for the body. Like other energy sources what isn’t used is stored in the body as fat.
Blood cholesterol is determined by a blood test. A lipid panel is conducted to show the levels of each component in the blood to come up with a total cholesterol number. While the total number is important, the breakdown of each will let you know what you have to worry or not worry about.
Healthy Cholesterol Levels:
* LDL – lower than 100 mg/dL
* HDL – higher than 60 mg/dL (40-60 mg/dL is considered acceptable)
* Triglycerides (VLDL) – lower than 150 mg/dL
* Total cholesterol – less than 200 mg/dL
Your doctor will give you a report detailing your numbers. If they are outside of the above numbers, you will more than likely discuss risk factors and also ways to change any unacceptable levels.
What Factors Affect Cholesterol?
Cholesterol comes from two sources: your body and your food. The body can regulate how much cholesterol it produces for its needs. Alone, it is not enough to meet all the needs so some cholesterol will have to come from food. This is the factor that is not so well controlled.
Carrying excess body weight puts you at risk for many diseases and conditions. Why is this so? Well, when the amount of fats taken in via food are more than the body needs for energy and cellular function, it gets stored as fat.
This fat increases our body weight and blood cholesterol levels. Usually this cholesterol is of the variety that contains is carried from the liver as LDL. Increased bad cholesterol levels also increase the risk of narrow arteries. The heart works harder when there is more tissue to oxygenate and fat has poor vascularity. Reducing your weight can lower your risk for heart attack, high blood pressure and lower the overall cholesterol number.
We don’t always eat what we should be eating. Let’s face it: greasy fatty food tastes better than natural fruits and vegetables. The preservatives and chemical processes that are used to create fast foods and instant foods along with Trans fats are damaging our bodies by raising bad cholesterol levels.
Natural foods do not contain any or very little preservatives. Fat calories are obtained from lean meats, nuts, beans and other foods. These healthier fats don’t add to the bad cholesterol but help to bolster levels of good cholesterol.
How many of us are leading a sedentary life? Office jobs and long work hours leave no time for exercise. It is enough that we get home, fix dinner, attend to the children and get to bed. Heading out to the fast food restaurant is a result of this lack of time too.
Weight plays a factor here as well. The more weight we pack on, the less energy we seem to have. When bodies are out of shape it is easy to get winded.
Technology like video games promotes less movement. When food is not burned as energy, it gets stored as fat. It is a vicious cycle to be sure.
Some people have an inclination towards high cholesterol based on their ethnic background. This doesn’t mean that others are not at risk. Anyone can develop high blood cholesterol levels if they possess the risk factors. Developing atherosclerosis from high levels of LDL cholesterol leads to heart attack and stroke.
Women are in a high risk category for heart disease. Their risk factors are obesity, diabetes and high blood pressure. Any one of these can increase cholesterol levels.
African Americans and Hispanics are also more likely to die of heart disease. But it is not just race, but genetic makeup, lifestyle choices and socioeconomic backgrounds that all work together to make up the profile. For example, lack of proper medical care brought on by lack of money or insurance means those people are less likely to get their cholesterol checked and receive treatment.
Diabetes is also prevalent among the African American population. Obesity plays a part in its development. High levels of blood cholesterol bring diabetics in line with risk for heart disease.
Smoking is a lifestyle source that not only affects the lungs but also cholesterol. The smoke from cigarettes is filled with toxins that are hazardous to the body. One toxin, acrolein is thought to affect the body’s metabolism of cholesterol. Quitting smoking can help lower your cholesterol levels to save your lungs and the rest of you.
Managing your health is also important to lowering cholesterol risk. If you have been diagnosed with diabetes, high blood pressure or heart disease, managing treatment will help keep blood cholesterol levels in check. Stay on your medications once they are prescribed. Do not voluntarily discontinue them without doctor approval.
Consequences of High Cholesterol
The heart is a muscle. It works to pump blood throughout the body. Oxygenated blood is picked up in the lungs and transported systemically and then back to the lungs again.
Since the heart is a muscle it can also grow larger. That happens when it has to consistently pump harder to get blood moving through the vascular system. When blood vessels are affected by LDL cholesterol, hard plaques have a chance to form, narrowing the lumen. In small vessels that are already narrow, they can become totally blocked.
The heart muscle gets its blood supply from coronary arteries. If these small arteries are blocked a heart attack can be the result. Coronary artery bypass or a stent (of applicable) are used to reopen the vessels for blood to flow. With bypass surgery, the blockage is bypassed for proper blood flow to the heart.
Strokes occur when blood vessels in the brain are blocked. How do they get that way? Any artery can be affected by sticky cholesterol plaques. Carotid arteries that supply the brain with blood are also subject to narrowing.
As blood flows through the vessels with greater pressure, one of these plaques can be dislodged. If it becomes lodged again in a smaller vessel it will totally block blood flow and therefore oxygen to brain tissue. Lack of blood can cause an infarct in the brain resulting in a stroke.
Researchers are still looking into the correlation between high insulin levels and cholesterol. It seems that uncontrolled diabetes especially can raise the levels of bad cholesterol in the blood. Lowering cholesterol levels can help those who are borderline diabetic from developing the condition.
How to Decrease Risk Factors
There are risk factors that we can control and those that we can’t that play a role in cholesterol levels. For the risk factors that we can control there is help out there to get you going in the right direction. Reversing cholesterol numbers now can stop nastier health problems before they begin.
Risk factors that you can’t control will often require outside intervention. This is where treatment options offered by a doctor come in. we will discuss those too.
Foods to Eat
Have you ever examined your diet? If not, try keeping a food diary for a week. Record everything that you eat and drink. You may be amazed at the choices that you are making. But, there is something that you can do.
It takes time to change a lifetime of poor dietary habits so go easy on yourself. Strive to change one habit every couple of weeks. They say that it takes about fourteen days to make or break a habit so get one under your belt before adding another.
Begin with making substitutions in your diet. Let’s say that you like macaroni and cheese. How about using whole wheat pasta and lower fat cheese? To make it creamy try adding some milk.
Processed foods are full of fat and unhealthy chemicals that are not good for anyone. This includes the ones that are endorsed by diet programs. Instead of spending money on those, try to purchase healthy natural ingredients and create your own dishes at home. The advantage here is that you know all of the ingredients in the food that you eat.
What foods can you purchase and give you the results you want? Here’s a short list:
* Grains (whole wheat, quinoa, barley, etc.)
* Lean meats (lean pork, beef, skinless/boneless chicken breasts)
* Seafood and fish (shrimp, salmon, tuna)
* Fruits and vegetables (greens, citrus fruits, berries, tomatoes, peppers, carrots, etc.)
* Nuts and oils(almonds, walnuts-unseasoned, olive, flaxseed)
* Beans (navy, lima, green, white, etc-dried not canned)
This is just a rudimentary list. The more natural foods are the more nutrients they will contain. Nuts and oils provide healthy fats that help to increase heart health and raise HDL levels. Eating more fiber will eliminate a portion of your fat intake from your body along with it. Finding a good book on nutrition will let you in on all of the health benefits of certain foods.
Foods to Avoid
This list can be almost as long as the good food list. We already know most of the foods on this list but need reminding from time to time. While many eating plans give you a day to eat freely, it is probably best not to do that so often until your cholesterol levels are back within normal range.
* Fast foods (especially ones that use trans fats in preparation)
* Processed sweets (baked goods and candy)
* Frozen quick meals (ones with too much saturated fat and not enough fiber)
* Fatty snack foods (donuts, chips)
* Full fat dairy (milk, yogurt and cheeses)
* Sodas (lots of sugar)
Your best asset will be reading labels. Here you will find total cholesterol, total fat, calories, protein, fiber and details about vitamins and minerals.
Exercise plays a big role in disease prevention. The body that is in optimal physical condition can do so many things. For instance, muscle mass is increased as well as tone. Toxins are better able to be eliminated from the body.
Increased oxygenation promotes clarity and mental focus. Your will also notice that you have more energy to do what you need to do each day. Don’t forget about those endorphins. They can lower incidents of depression by lifting your mood.
Exercise also lowers your weight. Weight management leads to lower incidence of diabetes and lower levels of bad cholesterol. As you age, you are better able to fight off diseases with increased immune response and a fit body.
Smoking is also a habit that needs to be broken. As we mentioned before, chemical toxins present in cigarettes has an effect on cholesterol levels. You will be able to increase your lung capacity when exercising which will increase your oxygen levels overall.
Now we get to the factors that are a little harder to control. Heredity plays a role in cholesterol levels. Families with a tendency towards heart disease and diabetes put family members on alert for what they might expect in their future. Being proactive is the best way to go.
Those who are diagnosed with high cholesterol do have a chance to turn things around. People with a history of high cholesterol may not be able to lower their numbers with diet and exercise alone. They need medication to help in the process.
Doctors prescribe cholesterol medication to work within the liver and lower the levels of LDL cholesterol. They have a slight effect on triglyceride and HDL levels. The most common ones are your statin drugs. Examples include: Zocor, Lipitor, Crestor and Pravachol. There are also cholesterol medications that are found in combination with other drugs when more than one problem exists such as high blood pressure.
A new class of cholesterol medication works in the digestive system. The one that is currently on the market is Zetia. It helps to eliminate cholesterol directly from the bloodstream before it can be absorbed by the intestines.
When taking blood pressure medication, make sure that you ask your doctor about side effects. Inform him if you are taking other medications so that there are no drug interactions that could result. One of the common side effects of statins is that it can affect the function of your liver. It is recommended that blood work be done to test for liver function every three months when you are taking them.
If you are more into holistic medicine, ask your doctor about supplements that work similar to statins. One that comes to mind is Red yeast rice. It has long been used in the Far East to help keep cholesterol in check. Supplements should not be taken in conjunction with traditional medications unless ordered by a doctor. The supplement may interfere with the efficacy of the statin drug.
Blood cholesterol levels are important to know. Do you know your levels? If you don’t know, have a blood test done. High levels of certain cholesterol components can put you at higher risk for diseases like heart disease, diabetes and stroke.
Even if you do have high cholesterol it is not too late to make a change. There are risk factors that are under our control (diet, exercise, obesity, lifestyle choices) and others that are not (heredity, age). Control what you can control and rely on your doctor to help you deal with the rest.
