Eggs can be used to prepare and refine numerous dishes. They are traditionally part of Easter and should symbolize fertility and new life. But the rumor persists that eggs are unhealthy. Cholesterol is the name of the villain to whom the eggs owe their bad reputation and is said to be partly responsible for atherosclerosis, stroke and heart attack. Although eggs are one of the high-cholesterol foods, fortunately this is not the only ingredient that eggs have. In addition to high-quality protein, vitamins and minerals, the egg yolk also contains lecithin (phosphatidylcholine), which largely blocks the absorption of cholesterol into the body – as has been confirmed in various studies. Therefore, you can enjoy your Easter eggs!
Did you know why boiled eggs sometimes have a green border around the yolk?
This is because protein compounds of the yolk release the micronutrient iron by cooking too long. At the same time, hydrogen sulfide forms in the egg white. Iron and hydrogen sulfide combine to form iron sulfide with its blue-green coloration and creates a blue-green border around the yolk, which, however, is completely harmless.
