What is afecting cholesterol?


We get cholesterol from two ways, from our body(mainly the liver) usually 1000 mg per day and from the food( from animals especially egg yolks,poultry,shellfish,whole milk and dairy products). Food from plants (fruit,vegetables,grains,nuts,seeds) don't contain cholesterol.
Saturated fatty acids foods is the main cause in raising blood cholesterol,which increase your risk of health disease.Trans fats also increase blood cholesterol,but dietary diet also plays a part.
Some excess dietary cholesterol is removed from the body through the liver.If you have heart disease you should limit your intake less than 200 mg.Still everyone should remember that by keeping their dietary intake of saturated and trans fats low,they can significantly lower their dietary cholesterol intake

Food high in saturated fat generally contain substantial amount of dietary cholesterol.
since cholesterol is in all foods from animal sources, care must be taken to eat no more than six ounce of lean meat fish and poultry per day and to use fat-free and low fat dairy products.High quality from the protein from vegetable source such as bean are good substitutes for animal sources protein.

Physical Activity

Regular physical activity increases HDL cholesterol in some people.A higher HDL cholesterol is linked with lower risk of heart disease. Physical activity can also help control weight, diabetes and high blood pressure.

What is cholesterol?


It is a soft,waxy substance found among the lipids (fats) in the mainstream and in all your body's cell. actually its an important part of a healthy body because it is used to form cell membranes, some hormones and is needed for other functions,But a high level of cholesterol in the blood (hypercholesterolemia) is a major risk factor for coronary heart diseases which leads to heart attack and stoke.
Cholesterol can't dissolve in the blood, they have to be transported to and form the cells by special carrier called lipoprotein. There two kind of Lipoprotein, one is Low density lipoprotein (LDL) which is bad cholesterol and High Density Lipoprotein (HDL) which is good cholesterol.

What is LDL cholesterol?

Low density lipoprotein is the major cholesterol carrier in the blood. if too much in the blood it can slowly build up in the wall of the arteries feeeding in the heart and brain also.Its can also join with other substances forming plage, a thick,hard deposit that can clog the arteries, known as atherosclerosis.
A clot (thrombus that form near this plague can block the blood flow to the part of the heart muscle and cause heart attack, while if its blocking the blood flow to the part of the brain cause stroke.
A high level of LDL cholesterol (more than 160 md/dl)reflects an increased risk of heart attack.So if you have heart disease your cholesterol must be lower than 100mg/dl, your doctor may prescribes lowering cholesterol medicine. That way LDL cholesterol is called "Bad Cholesterol"

what is HDL Cholesterol?

HDL tends to carry cholesterol away fram the arteries and back to the liver,where its passed from the body.HDL also removes excess cholesterol from plague and thus slows therir growth. that why HDL cholesterol is called "Good Cholesterol".Its seem to protect against heart attack. The low HDL level(less than 40 md/dl in man and 50 mg/dl in woman)its indicates greater rick of heart disease, as well as stroke.
