Recently, I saw someone online claim that a child's large head is due to frequently eating boiled eggs, almost 1-2 per day. Is a child's large head really caused by eating too many boiled eggs?

Eating too many boiled eggs generally does not cause a child's head to become larger; the two are not directly related.

A child's head circumference mainly depends on genetics and growth and development patterns. If the parents have larger head circumferences, the child's head circumference may also tend to be larger. From birth to age 5, a child's head circumference will grow along a normal growth curve. Only when a child's head circumference exceeds the normal range or grows too rapidly, accompanied by abnormal symptoms such as bulging fontanelles or vomiting, might it be related to conditions such as hydrocephalus or macrocephaly.

Boiled eggs are rich in nutrients such as protein and vitamins, which are necessary for children's growth and development. However, excessive consumption may increase digestive burden and potentially lead to other nutritional deficiencies due to an imbalanced diet. Parents should pay attention to regular check-up data regarding their child's head circumference and seek medical advice promptly if abnormalities occur, rather than worrying about the impact of boiled egg consumption on head size.
