Cholesterol is a soft, waxy substance found in all parts of the body. This includes the nervous system, skin, muscle, liver, intestines, and heart. It is made by the body and also obtained from animal products in the diet.
Alternative Names diet - cholesterol
Function
Cholesterol is manufactured in the liver for normal body functions, including the production of hormones, bile acid, and vitamin D. It is transported in the blood to be used by all parts of the body.
Food Sources
In foods, cholesterol is found in eggs, dairy products, meat, and poultry. Egg yolks and organ meats (liver, kidney, sweetbread, and brain) are high in cholesterol. Fish generally contains less cholesterol than other meats, but some shellfish are high in cholesterol.
Foods of plant origin (vegetables, fruits, grains, cereals, nuts, and seeds) contain no cholesterol.
Fat content is not a good measure of cholesterol content. For example, liver and other organ meats are low in fat, but very high in cholesterol.
Side Effects
In general, you have a greater risk of developing heart disease or atherosclerosis as your level of blood cholesterol increases.
Recommendations
More than half of the adult population has blood cholesterol levels higher than the desirable range. High cholesterol levels often begin in childhood. Some children may be at higher risk due to a family history of high cholesterol
