Cholesterol is a waxy substance that circulates through the blood stream and is found in the tissue of all animals, including humans. It only makes sense then that any food derived from animal sources contains cholesterol with the highest levels of cholesterol being found in egg yolks and organ meat such as liver or kidneys. There are two types of cholesterol, low-density lipoproteins (LDL) and high-density lipoproteins (HDL) which are considered good (HDL) and bad (LDL). If you have too much of the bad LDL cholesterol in your blood stream your risk for coronary artery disease, heart disease, and heart attack are greatly increased.
Cholesterol is a necessary nutrient that transports different compounds, including triglycerides, fatty acids, phospholipids, cholesterol, and small amounts of steroids and fat soluble vitamins, through the blood stream. Your body makes some cholesterol and the rest it needs comes from animal sources. Food derived from plant sources does not contain any cholesterol.
This doesn’t mean that all plant food sources are safe when it comes to high cholesterol. Plants and animal food sources with high levels of trans-fat, or saturated fat are actually more responsible for high cholesterol levels then foods that have just high cholesterol. Foods prepared in saturated fat found in many vegetable oils are more dangerous to your health then foods that are just high in cholesterol.
Cholesterol gets a bad rap, when in fact it is needed for many body functions. The body has the ability to make all the cholesterol it needs. Only animal foods that we eat like dairy products – whole milk, ice cream, and butter and beef, chicken, eggs, etc have cholesterol. Ingesting cholesterol from these sources will cause a rise in blood cholesterol levels, but in most cases it will be less than an equal rise, so it is best to eat smaller portions of animal foods.
How cholesterol forms?
Plants don’t produce cholesterol, so if we eat fruits, vegetables, and nuts, and use fruit or vegetable oils to cook with, we do not receive cholesterol directly from these sources. However, saturated fat from plants or animals can be converted into cholesterol by the liver. So the eating of saturated fat is the real culprit. Plant products have a redeeming nature – in most cases they carry more heart-friendly fats like monounsaturated and polyunsaturated (‘good fats’) along with the saturated fats.
The main source of blood cholesterol is the liver. It wraps particles of cholesterol into protein sheaths. These are called LDL (low-density lipoprotein). LDLs are placed into the bloodstream and are delivered to cells that need them. HDL (high-density lipoproteins) particles are used to clean the arteries of the cholesterol that is not needed. If the supply of HDL particles is not large enough to keep the circulatory system free of loose cholesterol that is delivered by LDL particles, the LDL particles may combine with free radicals be oxidized and penetrate the artery-cell wall hastening hardening of the arteries (atherosclerosis) and heart disease. The quantity of cholesterol in the blood at any one time is determined by the ratio of LDL levels to HDL levels. When your doctor does a lipids panel test on a sample of your blood, the results will show the total cholesterol, the LDL and HDL concentrations and your triglyceride level (other blood fats).
Some persons are genetically predisposed to high levels of blood cholesterol. If your father or paternal grandparents or mother or maternal grandparents died of heart disease – it is possible that you have inherited this risk factor and your levels of blood cholesterol are high because of it.
Otherwise, cholesterol accumulation in the blood comes from:
1) A diet of foods high in saturated fat and/or cholesterol
2) Lack of regular (aerobic) exercise
The easiest way to lower cholesterol is by regular aerobic exercise and keeping your weight down. Stay away from fatty, fast foods and eat a diet closer to nature – lots of fresh fruits and vegetables and small (4 ounce) cuts of meat (small portions of the animal foods that do contain cholesterol and saturated fat). You’ll feel better and your heart and arteries will love you for it.
If you have excess weight that you think you need to shed, then you should consider using fat burners. However, it is wrong to use them without the knowledge of their purpose and their mechanism in your body. They are simply substances in the form of capsules, tablets or syrups that cause an increase in the metabolic rate of your body. This is so as to see to it that the excess fats in your body are converted into another form of energy which can be used in a shorter time. In other words, best work in the same way that exercise works, only that they do the same job in a shorter time. There are different types which work in different ways but are meant to achieve the same goal.
Thermogenic fat burners work by increasing your metabolic rate by boost up your body temperature. Higher metabolic rates means faster processing of food, hence ensuring that there is none or minimal storage of fats in your body. This way, any activity you do, no matter how minimal, breaks down some fat from the ones stored. They are usually not taken but applied. They should be applied on a clean surface that has no hair. They are water soluble and they therefore do not stain clothing.
A natural and an all time fat burner is green tea. Green tea is quite high in the level of antioxidants it has; this and the presence of caffeine makes fat burning possible. Deoxidization is usually an initiation reaction to breaking down of fats, and caffeine acts as a catalyst. Ripped fuel fat burners usually employ the use of caffeine in fat burning. This is combined with aspirin and other stimulants that aid breaking down of fats. Blood sugar levels are usually kept in check by the addition of a certain carnitine, which ensures that your health is not at risk during the intake of the fat burner.
The fat burners that work best are those that are liquid based as opposed to those that are oil based. This is because of a higher rate of absorption owing to the fact that they do not have to undergo major digestion processes as opposed to those dissolved in oil. These usually come in pills that are taken orally. As you use best fat burner pills, you need to be careful what you eat and how you do it. Taking very little food does not help, because this usually sends the wrong messages to your body; it thinks that you ran short of supplies, and it therefore tries to give a “helping hand” by metabolizing it very slowly.
