Extractions: Introduction Essential Fatty Acids Cholesterol Trans Fatty Acids ... Required Intakes Fats provide a concentrated source of energy in the diet. The building blocks of fats are called fatty acids. These can be either saturated, monounsaturated or poly-unsaturated. Foods rich in saturated fats are usually of animal origin. Vegetable fats are generally unsaturated. Saturated fat raises the level of cholesterol in the blood. Cholesterol is present in animal foods but not plant foods. It is essential for metabolism but is not needed in the diet as our bodies can produce all that is needed. Raised blood cholesterol is associated with an increased risk of heart disease. Fats and oils are essentially the same. Fats tend to be solid at room temperature whilst oils are liquid. The term lipids include both fats and oils. Fats consist of fatty acids and glycerol. Nearly all the fats in our bodies and in foods are triglycerides, being made up of three fatty acid molecules to one glycerol molecule. There are about 16 different fatty acids commonly present in foods. The nature of fat depends on its constituent fatty acids. Fats can be classed as either saturated, monounsaturated or polyunsaturated. This depends on the type of chemical bonds present in the fatty acid. If a fatty acid has all the hydrogen atoms it can hold it is termed saturated. However, if some of the hydrogen atoms are absent and the usual single bond between carbon atoms has been replaced by a double bond, then it is unsaturated. If there is just one double bond then it is monounsaturated. If there is more than one then it is polyunsaturated. Most fats contain a proportion of each of these three basic types of fatty acid but are generally described according to which type predominates.

Extractions: Cholesterol is an important component of cell membranes and is vital to the structure and function of all cells in your body. However, cholesterol is a pre-dominant substance in antherosclerotic plaque, which may develop in arteries and impede the flow of blood. Cholesterol is not the only lipid circulating in your blood stream. Triglycerides are another form of fat that circulates in the blood. Cholesterol and Triglycerides being fats cannot dissolve in water. Therefore, to circulate through your blood which is mainly water they must be carried by protein packages called Apoproteins. The combination of Apoprotein and Lipid is known as lipoproteins. The main type of Lipoproteins are Low Density Lipoproteins (LDL a combination of 25% Apoproteins and 45% Cholesterol. It provides cholesterol for necessary body functions but in excessive amounts, it promotes cholesterol accumulation in the artery walls. 2. High-density cholesterol is a combination of 50% Apoprotein and 20% cholesterol. HDL tends to help remove excess cholesterol from your blood. Therefore, a relatively low ratio of LDL to HDL is desirable for lowering your risk for development of coronary artery disease.

Like carbohydrates and protein, dietary fat is an important source of energy for the body. Fat is the most concentrated source of energy in the diet, providing nine calories per gram compared with four calories per gram from either carbohydrates or protein. Dietary fat supplies essential fatty acids, such as linoleic acid, which is especially important to children for proper growth. In addition, fat is required for maintenance of healthy skin, for regulation of cholesterol metabolism, and as a precursor of prostaglandins, hormone-like substances that regulate some body processes. Dietary fat is needed to carry fat-soluble vitamins A, D, E, and K and to aid in their absorption into the intestines. It also helps the body use carbohydrates and proteins more efficiently.

The results appear in the November 5, 2003 issue of the Journal of the American Medical Association (JAMA). The study is the first clinical evidence that atherosclerosis, a progressive disease resulting from deposits of fatty substances such as cholesterol in the artery walls, can be rapidly reversed, says Esperion.
Extractions: The Food and Drug Administration (FDA) now requires food manufacturers to list trans fat (i.e., trans fatty acids) on Nutrition Facts and some Supplement Facts panels. Scientific evidence shows that consumption of saturated fat, trans fat, and dietary cholesterol raises low-density lipoprotein (LDL or "bad") cholesterol levels that increase the risk of coronary heart disease (CHD). According to the National Heart, Lung, and Blood Institute of the National Institutes of Health, over 12.5 million Americans suffer from CHD, and more than 500,000 die each year. This makes CHD one of the leading causes of death in the United States today. FDA has required that saturated fat and dietary cholesterol be listed on the food label since 1993. By adding
Extractions: The idea that too much animal fat and a high cholesterol is dangerous to your heart and vessels is nothing but a myth. Cholesterol is not a deadly poison, but a substance vital to the cells of all mammals. Researchers at the University San Diego School of Medicine UCSD point out that high cholesterol in those over 75 years of age is protective, rather than harmful and that low cholesterol is a risk factor for heart arrhythmias (leading cause of death if heart attack occurs). Researchers from the University of Denmark report that about 15% of cholesterol lowering drug users over the age of 50 will suffer from nerve damage as direct result of using statin drugs.

Most of us have heard this simple recommendation so often over the past two decades that we can recite it in our sleep. Touted as a way to lose weight and prevent cancer and heart disease, it's no wonder much of the nation - and food producers - hopped on board. Unfortunately, this simple message is now largely out of date. Detailed research -much of it done at Harvard - shows that the total amount of fat in the diet, whether high or low, isn't really linked with disease. What really matters is the type of fat in the diet.( ) Bad fats increase the risk for certain diseases and good fats lower the risk. The key is to substitute good fats for bad fats. And cholesterol in food? Although it is still important to limit the amount of cholesterol your eat, especially if you have diabetes, dietary cholesterol isn't nearly the villain it's been portrayed to be. Cholesterol in the bloodstream is what's most important. High blood cholesterol levels greatly increase the risk for heart disease. But the average person makes about 75% of blood cholesterol in his or her liver, while only about 25% is absorbed from food. The biggest influence on blood cholesterol level is the mix of fats in the diet. DIETARY FATS

Also known as "harding of the arteries", this is caused by the presence of excess cholesterol in the blood. The excess cholesterol accumulates on the lining of the blood vessels and forms a sticky, yellowish, thick plaque. This plaque can thicken to the point that it causes a blockage in the vessel, or part of it can break off and block another vessel in the body.
High density lipoprotein, also known as HDL, is considered the "good" cholesterol. HDL is produced by the liver to carry cholesterol and other lipids (fats) from tissues and organs back to the liver for recycling or degradation. High levels of HDL are a good indicator of a healthy heart, because less cholesterol is available in your blood to attach to blood vessels and cause plaque formation.
Cholesterol Test They contain about 7% cholesterol. Chylomicrons transport fats and cholesterol LDL molecules carry cholesterol from the liver to other body tissues. http://www.chclibrary.org/micromed/00042620.html
Extractions: The cholesterol test is a quantitative analysis of the cholesterol levels in a sample of the patient's blood. Total serum cholesterol (TC) is the measurement routinely taken. Doctors sometimes order a complete lipoprotein profile to better evaluate the risk for atherosclerosis coronary artery disease , or CAD). The full lipoprotein profile also includes measurements of triglyceride levels (a chemical compound that forms 95% of the fats and oils stored in animal or vegetable cells) and lipoproteins (high density and low density). Blood fats are also called "lipids." The type of cholesterol in the blood is as important as the total quantity. Cholesterol is a fatty substance and cannot be dissolved in water. It must combine with a protein molecule called a lipoprotein in order to be transported in the blood. There are five major types of lipoproteins in the human body; they differ in the amount of cholesterol that they carry in comparison to other fats and fatty acids, and in their functions in the body. Lipoproteins are classified, as follows, according to their density: Chylomicrons. These are normally found in the blood only after a person has eaten foods containing fats. They contain about 7% cholesterol. Chylomicrons transport fats and cholesterol from the intestine into the liver and then into the bloodstream. They are metabolized in the process of carrying food energy to muscle and fat cells.

The American Heart Association (AHA) says you need a certain amount of cholesterol for good health. But too much cholesterol in your blood can lead to clogged arteries and is a major risk factor for heart disease. (Read about " Coronary Heart Disease ") Your total blood cholesterol level can help determine your relative risk of developing heart disease. (Read about " Heart Risks ") The National Heart, Lung, and Blood Institute (NHLBI) says that, in general, the following overall cholesterol levels are considered acceptable for the average adult with no other known heart disease risk factors: Normal - less than 200mg/100dL High - over 240 mg/dL But those numbers don't tell the whole story, because not all cholesterol is bad. AHA says that a high level of high-density lipoprotein (HDL) cholesterol is believed to be beneficial. High-density lipoproteins (the so-called "good" cholesterol) remove cholesterol from the bloodstream. Under the latest guidelines from the National Cholesterol Education Program (NCEP) an HDL of less than 40 mg/dL is considered low for most adults, and indicates a potentially higher risk of heart disease. According to NCEP, HDL levels of 60 mg/dL or more help to lower your risk for heart disease.

Know Your Fats: Digestion And Absorption Of Food Fats Mary Enig discusses the role of fats in digestion. Fat digestion of cholesterol and other sterols is frequently not described accurately. http://www.westonaprice.org/knowyourfats/fat_absorption.html
Extractions: Back Home Basics Departments ... Know Your Fats Read this article in: Japanese By Mary G. Enig, PhD Maintenance of a healthy digestive system requires input from lipids, which include molecules such as cholesterol, appropriate saturated and polyunsaturated fatty acids, and other lesser known components such as glycosphingolipids. Cholesterol is the precursor to bile acids, which are needed to digest and absorb long-chain fatty acids. Cholesterol is also recognized for its physiological importance in the skin and the intestine where it plays an important structural role as a component of the organ membranes.Cells lining the digestive tract are particularly rich in cholesterol. Saturated fatty acids play their role in membrane integrity by providing appropriate fatty acids for certain parts of membrane structures. Among their various roles are the signaling activities that, for example, tell the gastrointestinal musculature when to contract. Polyunsaturated fatty acids also provide raw material for membranes, and work as precursors to the various prostaglandins, needed to maintain important functions of intestinal motility. Glycosphingolipids are lipids with single sugar molecules attached found in cell membranes, especially in the brain. They also protect against gastrointestinal infections, especially in infants and children. Whole milk is an adequate source, especially human milk. Fat digestion of phospholipids and other lipids makes up very minor, but sometimes important, parts of the building blocks for tissues. These special lipids are usually made by the body and diet is not the major source.

It is an essential part of cells in the body and is used to make certain hormones and digest fats. There are two different types of cholesterol. Blood, or serum, cholesterol circulates in the blood. Dietary cholesterol comes from the food we eat. Is all blood cholesterol the same? The chemical substance is the same. However, it is transported in the blood by different carriers. The relative amounts of cholesterol transported by each carrier can affect the risk of heart disease. The two major blood cholesterol carriers are LDL and HDL (see Table 1). Where do we get cholesterol?

Extractions: Cholesterol What is cholesterol? Dietary cholesterol is a waxy substance found only in foods of animal origin such as poultry, beef, fish, eggs and dairy products. Fruits and vegetables do not contain cholesterol. Cholesterol is necessary to keep the body functioning normally. The liver manufactures enough cholesterol for normal cell processes such as building cell walls and producing hormones. In children, cholesterol plays an important role in the development of the brain and nervous system. When cholesterol is combined with fats and proteins for use by your body, it forms particles called lipoproteins. There are two types of lipoproteins. Low-density lipoproteins (LDL or "bad" cholesterol) are associated with the buildup of excess cholesterol on the walls of the arteries. This buildup (plaque) forms on the inner walls of the arteries, reducing blood flow to the heart and brain. High-density lipoproteins (HDL or "good" cholesterol) remove excess cholesterol from the bloodstream and carry it to the liver for excretion. HDL prevents the accumulation of cholesterol and other fats along the artery walls. Why does cholesterol matter?

Extractions: (This sheet is a copy from the above website as of March 2001) Cholesterol and fat are often confused. This is understandable because there is a strong link between the two. What is cholesterol? Cholesterol is a fatty substance produced naturally by the body and appears in our blood in different forms. It has many good uses. Some cholesterol comes from food, but the body can make all it needs. What are the different types of cholesterol? What are triglycerides? Triglycerides are a type of fat occurring naturally in blood. They are formed from the digestion of fats in food. The recommended level of triglycerides is less than 2 mmol/litre. What's wrong with high blood cholesterol? Too much cholesterol in the blood causes fatty deposits to build up in blood vessels, making it harder for blood to flow through. The gradual blocking of blood vessels in the heart may lead to a heart attack. The following levels of blood cholesterol are a useful guide: Desirable: less than 5.5 mmol/litre
