However, a recent study has revealed that the cholesterol content of eggs is now much lower than it was 10 years ago and they also now contain higher levels of vitamin D which is fantastic for protecting the bones and preventing diseases such as osteoporosis.
The U.S study found that modern eggs contain around 13 per cent less cholesterol and 64 per cent more vitamin D when compared with eggs ten years ago.
Experts believe the change could be attributed to the fact that hens are no longer fed bone meal, which was banned in the Nineties after a BSE crisis. Now most hens live on a diet of wheat, corn and high-protein feed.
The U.S findings have been back by British research which found that a medium egg contains about 100mg of cholesterol, which is a third of the 300mg recommended daily limit.
