Newer research shows that for most healthy people, eating whole eggs does not significantly increase blood cholesterol levels.

The current scientific understanding has revealed a more complex picture:The outdated belief was based on the assumption that dietary cholesterol (from food) directly and strongly affects blood cholesterol levels. 

• The liver regulates cholesterol. Your liver produces the majority of the cholesterol in your body. When you eat more dietary cholesterol, your liver naturally produces less to compensate.
• Saturated fat is the real culprit. Saturated fat and trans fat have a much greater impact on raising “bad” (LDL) blood cholesterol than dietary cholesterol. A cooked breakfast with high-saturated fat bacon or sausage is more likely to negatively affect your heart health than the eggs themselves.
• The overall diet matters more. The context of your entire diet is more important than the cholesterol in a single food. Studies show that eggs eaten as part of a low-saturated-fat diet do not increase LDL cholesterol and may even improve cholesterol profiles.
• Eggs offer nutritional benefits. Eggs are rich in protein, vitamins, minerals, and antioxidants, and are a valuable part of a balanced diet.
