All you need to know about egg yolk

Egg yolks are the yellow part at the center of an egg. They contain high levels of cholesterol but also provide a range of vital nutrients and health benefits.

The review highlights several benefits that the nutrients and proteins in egg yolk may provide, including:

• A lower risk of gastrointestinal distress: This benefit may be due to egg yolk proteins, such as phosvitin, which may reduce the number of compounds in the body that cause inflammation.
• A boosted immune system: Certain compounds called sulfated glycopeptides are present in the membrane of the egg yolk. These may stimulate the production of macrophages, which are cells in the immune system that protect the body against disease and infection.
• Lower blood pressure: The review notes that egg yolk contains several compounds called peptides that research has shown to reduce blood pressure significantly in rats. High blood pressure is a risk factor for cardiovascular disease.
• Reduced risk of vision problems: The American Heart Association state that yolks are a significant source of lutein and zeaxanthin. These carotenoids may protect against cataracts and macular degeneration, two common eye problems that often develop after the age of 55 years.
