The level of blood cholesterol is affected more by the amount and type of fat in the diet than the amount of dietary cholesterol. A high intake of saturates , and fat of all types, can increase the amount of cholesterol produced in the liver and so the amount in the blood. Dietary cholesterol has a weaker effect of blood cholesterol levels. Cholesterol is found only in foods of animal origin. For most people, monitoring dietary cholesterol intake is much less important than reducing saturates intake.
Soluble fibre is a type of fibre found in foods such as oats, fruits, vegetables and beans.
It has been shown to reduce blood cholesterol levels by reducing the amount of cholesterol absorbed from the intestine.

They may help to reduce the level of blood cholesterol if used as a part of a healthy balanced diet. As coronary heart disease is the leading cause of death in the UK, more attention should be paid to prevention of the disease. Prevention is important for everyone but particularly for people with many risk factors.
