Fat Diet, Regulating lipid Metabolism.

The dietary fats are an important regulator of lipid metabolism. These absorbed as chylomicrons and formed in direct relation to the fat content of the diet. As an example the strict vegetarians have blood lipid values ​​that consumers in mixed diets and is also different composition of fatty acids.

Saturated fatty acids are formed by chains of carbon atoms, which are joined together by single bonds, allowing them to crystallize easily and be solid at room temperature. All animal fat other than fish are rich in saturated fatty acids. From vegetable oils only palm and coconut are rich in these substances. A high intake of saturated fats raise total cholesterol and LDL-cholesterol (bad cholesterol) and scientific studies can relate to an increased risk of cardiovascular disease.

The mechanism by which some types of fatty acids may increase the concentration of cholesterol in blood is by decreasing LDL receptor expression in cell membranes especially in liver cells (hepatocytes). The lack of LDL receptors prevents cholesterol between cells and causes increased LDL-cholesterol (bad cholesterol) levels.
