Cholesterol is a fat which is responsible for the production of bile acid and vitamin D in our body. It is a fat which can be beneficial to humans in small quantities only. HDL or High Density Lipoprotein is known as good cholesterol. High-density lipoproteins (HDLs) carry excess cholesterol back to the liver, which processes and excretes the cholesterol. Cholesterol levels can be measured with the help of a blood test. If we have 3.5 mg of total cholesterol, or less, for every 1 mg of HDLs, then our cholesterol ratio is considered as ideal.

HDLs are "good" cholesterol i.e the more HDL we have, the lower your risk for developing heart disease. HDL is also converted into energy by our body. Low Density Lipoprotein is "bad" cholesterol. High LDL levels are linked to increased risk for heart disease. Low-density lipoproteins (LDLs) carry cholesterol to the tissues. LDL is responsible for choking the arteries that supply blood to the heart. Eggs, meat, junk food like pizzas and burgers contain high levels of cholesterol. Eggs contain cholesterol in their yolks.
