Cholesterol

Fat forms an important part of a healthy diet as it provides fat soluble vitamins A D E & K, as well as essential fatty acids.

 

Eating too much of saturated fat increases the level of cholesterol. Cholesterol is metabolised in the liver and is carried in blood by proteins LDL’S and HDL’S. LDL cholesterols referred as bad cholesterol because high levels in blood can result in it being deposited on the wall of the blood vessel eventually leading to atherosclerosis leading on to a cardiovascular event like heart attack.

 

LDL [Low Density Lipoprotein]: The liver secretes a class of low density lipoproteins called very low density lipoprotein, which contain free and esterifies cholesterol, triglycerides and phospholipids.LDL is also referred to as bad cholesterol. This as already mentioned goes into the circulation and deposits fat in the blood vessels which in turn can result in a cardiovascular event.

 

HDL [High Density Lipoprotein]: This is referred to as good cholesterol. It carries the fat to the liver to be disposed of. Dietary fibre especially soluble fibre has a modest cholesterol lowering effect. Monosaturated lower LDL cholesterol, while maintaining or even raising the HDL cholesterol levels reducing the risk of heart disease.

 

Obesity and taking an excessive amount of saturated fat is a good example and a common cause of raised Triglyceride levels .Of the total intake of calories 40% comes from fat. Fat contains nine calories per gram as compared to protein and carbohydrate which contains four calories per gram.

 

A vegetarian diet has a large and significant cholesterol lowering effect associated with the substitution of vegetable protein for animal protein, this results in low fat and cholesterol content of the diet.

 

A number of studies carried out have described the association between fat intake and cholesterol levels and coronary artery disease. Adult cardiovascular disease and obesity has its roots in children and young adults.
