Cholesterol Levels and How To Use Them
What are Cholesterol levels and lowering your cholesterol levels?
Cholesterol levels are the difference between life and death. You must reduce your cholesterol levels. A high cholesterol level means you will have a heart attack.
Cholesterol fact, or cholesterol fiction?
The answer is both simple and complex! Simple, in that cholesterol levels themselves are not the problem. Complex, because cholesterol levels signify a different problem (albeit an easy one to resolve).
What are cholesterol levels
Simply put, when your doctor measures your cholesterol level, he discovers how much of the varying types of cholesterol are circulating in your blood. As your doctor would have you believe, high cholesterol levels are bad and low cholesterol levels are good – because that’s
what he’s paid to tell you!
Regardless of the amount of cholesterol in your diet, your liver will make however high or low a cholesterol level your body needs, period. High cholesterol diet or low cholesterol diet, your cholesterol levels will be the same – why? Check out our cholesterol page for full details.
Put simply, it doesn’t matter whether your diet is high in cholesterol or low in cholesterol – cholesterol is so important to your body that it can, and does make your cholesterol levels exactly what it needs them to be.
Does it matter that you have “high cholesterol levels”?
Of course it does, but not for the reasons you think. High cholesterol levels signify that you are deficient in Vitamin
C, which is used to repair the continual damage to your arteries. If you can’t fix them, the body needs to do something else and high cholesterol levels show that your body is using its “reserve” repair material instead of its first choice, nothing more, nothing less.
As explained on our cholesterol page, the issue is not your high cholesterol levels, it is your dietary lack of vitamin
C that causes high cholesterol levels, so stop worrying about your and cholesterol levels and start worrying about your vitamin C intake!

Discovery Of Gene For High Cholesterol In Animal Blood Offers Hope For Reducing Risk In Humans
Scientists at the Southwest Foundation for Biomedical Research (SFBR) in San Antonio have found a gene that causes high levels of bad cholesterol to accumulate in the blood as a result of a high-cholesterol diet. Researchers studied a strain of laboratory opossums developed at SFBR that has normal blood levels of “bad” low-density lipoprotein (LDL) cholesterol when fed a standard low-cholesterol diet, but extremely elevated levels of LDL cholesterol when fed a high-cholesterol diet…

Low Cholesterol Diet – Decrease Risk of Heart Diseases
What is Cholesterol?
Cholesterol is a fatty wax lipid that can be found in the cell membranes of humans and animals.
Cholesterol is a tricky little devil, because if it gets out of hand you could have a serious health risk, including heart attack and other potentially fatal conditions. That is why it is so important to have a low cholesterol diet, because it reduces your risk of having a heart attack or stroke. High cholesterol is something you need to avoid. It can cause many conditions including heart disease.
By having a low cholesterol diet, you are less likely to contact heart disease than someone who eats a high cholesterol diet.Well, whether or not you have high cholesterol, eating too many high cholesterol foods will give you high cholesterol. So, manage your diet and eat right, and remember that a low cholesterol diet is important for your health.
Causes, Symptoms of High Cholesterol
Nobody wants High cholesterol. When you hear the dreaded words from your doctor saying you have high cholesterol, you are probably thinking something along the lines of – “Now. I will never be able to eat my favorite food again!” But do not worry, there are many low cholesterol diets that can be good for you and taste well all at the same time. First let’s look at the causes of high cholesterol. In most cases, weight plays a large role in high cholesterol because of the food you eat and the amount of food you eat.
Sometimes it can be as simple as losing a few pounds to lower your cholesterol levels, but other times you simply can do nothing. You lose weight but your cholesterol levels are still the same. This can be an example of hereditary cholesterol, which means your high cholesterol levels could be the result of one of your family members having high cholesterol. A low cholesterol diet will help to keep your cholesterol levels down but it will be harder because it is something in your genes that makes your cholesterol high. Also stress can raise your cholesterol so practicing stress relief is a good idea, and exercise may be the perfect option for you, exercise can both decrease your stress and your cholesterol levels all at the same time.
Symptoms of high cholesterol can be, fatigue, depression and other emotional conditions. A good suggestion when starting a low cholesterol diet would be to avoid fatty, unhealthy foods, like french fries, and other fast foods that are high in cholesterol. Junk food is never good, so when you are trying to stay on a low cholesterol diet, try to avoid these types of foods at all costs. Yes I know you love those kind of foods, but it is not the end of great tasting foods for you yet. Today there are many substitutes for junk foods that can be made right at home with ingredients that will not raise your cholesterol levels.
It is good to go to your local book store and find a low cholesterol diet cookbook, because a lot of the time you can find delicious recipes that are much lower in cholesterol than other foods. For example if you get hungry for french fries while on a low cholesterol diet, consider this – most low cholesterol cookbooks will have a recipe for oven fries. These are a delicious substitute for regular french fries and they taste great! Of course if you cannot find this recipe feel free to go online and find low cholesterol recipes for you and your family to enjoy.

Does A High Cholesterol Diet Increase Cholesterol In The Body?
If you’ve been diagnosed with high cholesterol, you’re probably trying to modify your existing diet to lower your cholesterol. You might be surprised to learn that a high cholesterol diet is not necessarily the culprit behind your high serum lipid levels.
Let’s talk about cholesterol first, and then we’ll get into the effects of a high cholesterol diet. What is cholesterol? Cholesterol is a fatlike substance that is synthesized by the body. That’s right! We make it in our bodies. Only animal products contain cholesterol. If it didn’t have a liver, it doesn’t have cholesterol! As a matter of fact, I get a kick out of food labels that tout “No Cholesterol” as a marketing tool when the food item never had a chance of having cholesterol in the first place. I know what you’re thinking. Some items have cholesterol and it doesn’t appear to be an animal product. This is simply because they used animal fat to produce the product.
Cholesterol is used in the body as a structural component of cell membranes and in the synthesis of some hormones as well as Vitamin D. Doesn’t seem so bad, right? Wrong. The problem is that when cholesterol is being transported in the blood stream, it tends to stick to the walls of arteries which of course, isn’t a good thing. When there’s a high amount of cholesterol in the body, this is far more prevalent. So, does a high cholesterol diet raise the level of cholesterol in the body?
Yes and no. There, how’s that for fence-sitting! Seriously, the actual cholesterol component in a high cholesterol diet doesn’t necessarily raise blood levels of cholesterol. More importantly is the fat that is usually in the high cholesterol items. Remember how I told you that cholesterol is only in animal products? Well, animal products such as steak contain a lot of fat. In addition, foods that are not even high in cholesterol and are high in fat are generally what need to be eliminated when trying to lower high cholesterol levels.
The fat that we’re talking about here is that nasty old saturated fat. It has been well documented that high levels of saturated fat in a person’s diet raise total cholesterol levels and more importantly, LDL (the bad one). Saturated fat is found in fatty meats, greasy, salty snacks and most baked goods as well as other high fat foods. A high cholesterol diet may or may not contain high saturated fatty acids.
In addition, diets high in fat are often consumed by people who are overweight. People who are overweight tend to not exercise (not that all overweight people don’t exercise). Carrying extra weight and not exercising contribute to increased blood cholesterol. So, you can see there are a lot of contributing factors to high cholesterol than simply a high cholesterol diet.
More importantly than worrying about a high cholesterol diet, your diet will be lower in cholesterol naturally if you lower your fat intake. Keep your fat intake less than 30% of your daily intake. If you’ve been diagnosed with high cholesterol, go for less than 25% of total calories. Watch saturated fat intake closely. Work towards getting your fat intake from healthier sources such as fish and oils like canola oil.
There’s also a significant portion of people with high cholesterol that don’t follow a high cholesterol diet, do not consume high amounts of fat and do exercise regularly. These people are merely genetically predisposed to having high cholesterol. Though they may achieve some lowering of cholesterol through increasing their efforts at exercise and adding foods known for lowering cholesterol, they will probably still need a medication.
Look closely at a high cholesterol diet and re-evaluate it based on the amount of fat it contains. Lower your fat intake overall and you’ll probably notice you are not eating foods high in cholesterol, either. This is the best way to avoid letting your diet affect your blood cholesterol.

Cholesterol Levels and General Health
People with high blood cholesterol levels are very exposed to developing heart disease. High cholesterol levels are common to people with ages over 50, people with weight problems, people with gastro-intestinal disorders and people with diabetes. High blood cholesterol levels can be the result of either overproduction of the substance (due to liver dysfunctions) or the inability of the body to eliminate it. However, apart from physiological factors that enable the accumulation of cholesterol inside the organism, there are also many other external factors that contribute to cholesterol build up: inappropriate diet, sedentary lifestyle, smoking and alcohol abuse.
Although the body is able to produce the amount of cholesterol it needs for sustaining its normal activity, a high-cholesterol diet can significantly increase blood cholesterol levels. Foods of animal origin are rich in cholesterol and saturated fats that are very harmful to the organism when they are consumed in large amounts. You should replace meats and dairy products with vegetables, cereals and fruits in order to maintain normal cholesterol levels. Simple carbohydrates (sweets) also enable cholesterol to build up inside the body and therefore should be avoided.
Proper physical exercise is very important for keeping your blood cholesterol levels in check. Regular physical exercise improves blood circulation and helps in the elimination of excess cholesterol. Exercise frequently and you will be able to maintain normal cholesterol levels and lose extra weight.
Smoking is considered to be a major factor of risk in heart disease. Smoking facilitates cholesterol to deposit inside arteries, where they can cause blockage, perturbing the normal blood flow. If you have high blood cholesterol levels and you are a smoker, it is advised to stop smoking. Alcohol also contributes to the accumulation of cholesterol in the bloodstream and therefore it should be avoided.
Within normal limits, cholesterol is very important to the organism. The liver produces cholesterol (a waxy, viscous substance) in small amounts, as it is required in certain physiological processes. Without cholesterol, the body is unable to produce hormones (testosterone and estrogen), vitamin D (fortifies bone tissues) and bile (a very important substance used in digesting fat). While in small quantities cholesterol is benefic for the organism, in excess it can cause a lot of harm. Cholesterol is not soluble in blood and therefore it accumulates and deposits inside arteries, slowing down the normal blood circulation. High cholesterol levels considerably increase the risk of cardio-vascular diseases and even heart failure.
It is very important to know that there are several types of cholesterol. When you have your cholesterol levels checked, you are usually told the total cholesterol level. Total cholesterol level consists of high-density lipoprotein (HDL), low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL). Low-density lipoprotein is also known as “bad cholesterol” and this substance can be harmful to the human body when it accumulates in excess. Bad cholesterol (LDL) accumulates inside arteries and perturbs normal blood circulation. Good cholesterol (HDL) is benign to the organism, as it collects low-density lipoprotein from the bloodstream and brings it back to the liver.
By keeping a healthy diet and by exercising regularly, you will be able to raise your good cholesterol levels, while reducing bad cholesterol levels. By making improvements in your lifestyle, you will be able to maintain your total cholesterol levels in check.
