When peoples lifestyle includes a lot of stress they tend to eat a lot of "fast foods" and this is loaded with bad Cholesterol or (LDL's). This second process is accountable for another 400 mg - 500 mg of cholesterol a day. Once eaten, the cholesterol in the food goes into the intestines to await digestion. Chylomicrons which are fatty particles containing mainly triglycerides, but also cholesterol, phospholipids and protein are produced in the intestinal wall. Once the Chylomicrons enter the bloodstream, they attach to receptors on the capillaries. A large percentage of triglycerides are broken down and released into circulation. The remainder of the Chylomicrons now richer in Cholesterol continues in circulation until it reaches the liver and is absorbed. Since cholesterol is like a fat, it is hydrophobic or is unable to mix with water or blood. In order for it to be carried through the blood, the liver the combines the cholesterol with triglycerides and proteins (called lipoproteins) to form packages called very low-density lipoproteins (VLDL). These packages of VLDL's, account for 10-15 percent of the cholesterol in the body, they are dispersed into the bloodstream and are transported to tissue capillaries where triglycerides are broken down and either used for energy or stored by muscle or fat cells. After the release of the triglycerides, the package now has a higher percentage of cholesterol. This package is now called low-density lipoproteins or "LDL's". LDL's, also known as the "bad" cholesterol. LDL's are transported through the bloodstream to build cells, make hormones, and act as insulation for nerves. Low-density lipoproteins account for 60-70 percent of the total amount of Cholesterol in the body. This package of Cholesterol is very useful to the body. It is necessary in the membranes of cells. If the cell gets too cold, the cholesterol kept the cell from freezing or turning solid.
