How long should eggs be boiled?
Before boiling, soak eggs in cold water to reduce internal pressure. Use medium heat and bring cold water to a boil to prevent cracking and nutrient loss. Boiling eggs seems simple but requires precise timing. Too short a time leaves the yolk undercooked, while too long makes the egg tough and unpalatable.How long should eggs be boiled? Experts advise: 5 minutes is optimal. Specific method: Start with cold water. Once boiling, count exactly 5 minutes. This ensures harmful pathogens are eliminated while preserving nutrients relatively intact. Note: Boiling eggs for over 10 minutes triggers chemical changes inside.The protein structure becomes denser, making it harder for digestive enzymes in stomach acid to break down the protein, thus becoming more difficult to digest. Additionally, prolonged heating causes methionine in the egg to break down into sulfides. These sulfides react with iron in the yolk to form iron sulfide, which is poorly absorbed by the body, resulting in significant nutrient loss. While boiled eggs are nutritious, excessive consumption can lead to indigestion. Therefore, it's advisable not to eat too many boiled eggs, generally limiting intake to no more than one per day.

Is egg yolk or egg white better?
Both egg yolks and whites contain high-quality protein with excellent digestibility. However, their other nutritional components differ significantly: egg whites are primarily composed of ovalbumin, while egg yolks are rich in not only yolk phosphoproteins but also fats and micronutrients (vitamins and trace elements), particularly iron, phosphorus, and vitamins A, D, E, and B complex.
For infants under 1 year old and over 4 months old, egg yolks are recommended. Start with about 1/4 of a yolk and gradually increase to 1–1.5 yolks as tolerance develops. Children over 5 years old can begin eating whole eggs. Some children may experience allergic reactions to eggs, primarily due to an allergy to ovalbumin. In such cases, avoid egg whites and even whole eggs initially. Later, gradually introduce small amounts of egg yolk to achieve desensitization.However, for the vast majority of children, eggs—especially egg yolks—are packed with nutrients that benefit growth, physical development, brain and nervous system maturation, and cognitive enhancement. Their consumption should not be neglected; aiming for one egg daily is ideal.
