Eggs and cholesterol - what is the connection?

Eggs and cholesterol - what is their relationship? Many people who have had high cholesterol in the past have been told stories of the big bad egg, and how it can raise cholesterol. But is there any truth to this? Lets investigate.

What does an egg contain?

  • The egg white - this contains about 11% protein, no fat and no cholesterol.
  • The egg yolk - this is fatty part of the egg, containing around 27% fat. It also contains around 15% protein. It is full of fat soluble vitamins such as A, D and E, and many B vitamins including B12.
  • Eggs contain the minerals iron, zinc, calcium and selenium.
  • They also contain saturated fat (about 1.6g per egg) and cholesterol.
  • It depends on the size of the egg, but the cholesterol content is around 200-220mg (per egg).


What do the egg-sperts say?


The National Heart Foundation of Australia suggests that eating up to 6 eggs per week is not linked to any adverse cardio-vascular disease outcomes. There is a proviso - you must also be following a diet low in saturated fat. Apparently egg consumption has only a small effect on blood cholesterol levels.


eggThe Heart Foundation does caution people with diabetes against eating too many eggs. There is some research suggesting that increases in egg consumption in diabetics may increase risk of heart disease. Reasons are unknown at this stage.


The American Heart Association makes note that for people without raised cholesterol, who should be aiming to keep cholesterol under 300mg/day, an egg a day does not pose a particular problem so long as other cholesterol containing foods are kept to a minimum. They do suggest that people with high cholesterol limit their daily cholesterol intake to under 200mg, so with each egg containing over 200mg of cholesterol on average, an egg a day might push the boundaries.

The bottom line with eggs and cholesterol

You can make your own decision based on the evidence reported. The main thing to keep in mind is that saturated fat has more of an impact on you cholesterol levels than does dietary cholesterol itself. So if you're tossing up between a fatty piece of bacon or a poached egg on toast, the egg is clearly the winner. Egg-cellent.
