For a long time, egg yolk was considered harmful due to its high cholesterol content. The cholesterol theory of atherosclerosis, proposed by Nikolai Anichkov in the last century, explained why excessive consumption of yolks could negatively affect the heart and blood vessels.
Cholesterol and Myths About the Yolk
Modern studies show that the body can regulate the absorption of cholesterol from food. The yolk is also rich in important nutrients: calcium, iron, zinc, thiamine, folic acid, and vitamins B6 and B12. Therefore, it is more beneficial than harmful when consumed in moderation.
Egg White: Benefits and Possible Risks
Egg white contains proteins with antimicrobial properties. They can affect the gut microbiome, sometimes reducing the efficiency of digestion and nutrient absorption. From the perspective of potential harm, the egg white may be a more "risky" component, especially when consumed excessively or in cases of individual sensitivity.
General Recommendations
Despite the differences, eggs are generally healthy. Moderate consumption of 2–3 eggs a day — both yolk and white — does not harm the body and provides a complete set of nutrients.
