The Lipid library is an area that will be constantly growing.
As new information is added to the lipid information site, relevant information
will be archived here in the Lipid Library. Reference material can be
found here to help you better understand cholesterol and its Affects on
the body
Glossary
Atherosclerosis - is a type
of "hardening of the arteries" in which cholesterol, fat, and other blood
components build up in the walls of arteries. As the condition progresses,
the arteries to the heart may narrow, reducing the flow of oxygen-rich blood
and nutrients to the heart.
Cholesterol - is an odorless, white, waxy, powdery
substance. You cannot taste it or see it in the foods that you eat. Your
body needs some cholesterol in order to function normally.
Coronary heart disease - commonly referred
to as CHD, is caused by the narrowing of coronary arteries (through which
oxygen-rich blood and nutrients are supplied to the heart). It is caused
by atherosclerosis. In time, the inadequate supply of oxygen-rich blood
and nutrients damages heart muscle and can lead to chest pain and heart
attack and can possibly lead to death.
Fat - is one of the essential nutrients that
supply calories to the body. Fat provides 9 calories per gram, more than
twice the number provided by carbohydrate or protein. Small amounts of fat
are necessary for normal body function.
HDL cholesterol - or high-density lipoprotein,
helps carry the "bad cholesterol" away from the walls of the arteries
and returns it to the bloodstream, thus preventing buildup of cholesterol
in the artery walls. That's why its called the "good cholesterol."
Hydrogenated fat - is liquid, unsaturated fat
that has been changed by a chemical process into a more solid, saturated
fat. Though this improves the shelf life of the products in which this fat
is used, it also increases the saturated fat content. It is commonly found
in cakes, cookies, snacks, an other food products.
LDL cholesterol - the "bad cholesterol" or
low-density lipoprotein, carries the largest amount of cholesterol in the
blood and is responsible for depositing cholesterol in the artery walls.
An elevated LDL cholesterol level is associated with risk of heart disease.
Lipids - are fatty substances that are present
in blood and body tissues and include cholesterol and triglycerides.
Lipoproteins - are protein-coated packages
that carry fat and cholesterol through the body. Lipoproteins are classified
by their density.
Monounsaturated fat - a slightly unsaturated
fat that is found in greatest amounts in foods from plants, including olive
and canola (rapeseed) oil. When substituted for saturated fat, monounsaturated
fat helps to reduce blood cholesterol.
Polyunsaturated fat - a highly unsaturated
fat that is found in food products derived from plants, including safflower,
sunflower, corn, and soybean oils. Like monounsaturated fat, it is a healthier
alternative to saturated fat.
Saturated fat - is usually solid at room temperature.
It is commonly found in animal products, such as meat, poultry, egg yolks,
and dairy products. it is also found in a few vegetable products, such as
coconut and cocoa. Saturated fat raises blood cholesterol more than anything
else in the diet.
Total cholesterol - is the total of the HDL
cholesterol, LDL cholesterol, and VLDL cholesterol.
Triglycerides - are fat-like substances that
are carried through the bloodstream to the tissues. Much of the body's fat
is stored in the form of triglycerides for later use as energy.
Unsaturated fat - is usually liquid at refrigerator
temperature. It is primarily found in vegetable products. The two kinds
of unsaturated fat are monounsaturated fat
and polyunsaturated fat.
VLDL cholesterol - or very-low-density lipoprotein,
carries cholesterol and triglycerides from the liver. After it sheds the
triglycerides, it becomes LDL cholesterol.
