Oily fish such as herrings are rich in omega 3 fatty acids which can help to reduce LDL cholesterol level. Oats contain soluble fibre which is also known to be particularly effective in reducing blood cholesterol levels. The fibre is able to bind to bile acids which stop the body from being able to re-use them. Cholesterol is then taken from the blood to make new bile acids, so levels fall.

Don't worry about using an egg; eggs contain dietary cholesterol which has little or no effect on blood cholesterol.
