5.Cholesterol 

Cholesterol is essential to our well-being, as it helps to build cell membranes, to produce hormones, and to manufacture bile acids. However, the liver is capable of producing all of the cholesterol needed for good health. While cholesterol is essential, excess intake is harmful. The daily intake of cholesterol should not exceed 300 milligrams regardless of the calorie intake.

 

Cholesterol is a fatlike substance found in every cell of the body. Everyone has cholesterol, but people who eat excessive amounts of fat may have high levels of cholesterol in their blood. There the excess cholesterol accumulates and builds up deposits called plaque on the walls of the blood vessels. People with high cholesterol levels are more likely to suffer from heart disease and high blood pressure. 

 

Types: 

1.Low-density lipoproteins (LDLs) 

2. High-density lipoproteins (HDLs), 

 

 There are two kinds of cholesterol.

1. Cholesterol attaches to proteins in the blood called lipoproteins. Low-density lipoproteins (LDLs) carry cholesterol that builds up plaque, so LDL-cholesterol is considered "bad" cholesterol. 

 

 2.High-density lipoproteins (HDLs), on the other hand, carry cholesterol to the liver, where the body can get rid of it; therefore HDL-cholesterol is regarded as  "good" cholesterol.
