Eggs also contain fats, lecithin, vitamins, and essential minerals like iron, calcium, and potassium. They provide multiple amino acids necessary for the human body, with a protein composition similar to that of human tissue. The amino acid ratio in egg protein aligns well with physiological needs, making it highly absorbable with a utilization rate exceeding 98%, offering significant nutritional value.Eggs are rich in calcium, phosphorus, iron, and vitamin A, abundant in B vitamins, and contain numerous other essential vitamins and trace elements. They serve as an excellent nutritional supplement for children, the elderly, postpartum women, and patients recovering from hepatitis, tuberculosis, anemia, or surgery. Delicious, affordable, and nutrient-dense, eggs truly are an ideal natural "tonic."
We eat eggs daily, but how much do we really know about them?Let's see what nutritionists have to say—
While eggs are beneficial, consuming them in moderation is essential. Recent surveys indicate that among urban workers, some young people engaged in mental or light physical labor consume 5–6 eggs daily to boost nutrition. Some middle and high school students eat 3 eggs for breakfast and 1–2 eggs for lunch and dinner.In some rural areas, new mothers consume 10–15 eggs daily, reaching 300–450 eggs during the postpartum confinement period. They believe, "Eggs are nutritious; eating more builds strength." In reality, excessive consumption can have adverse effects on health.
First, eggs contain high levels of cholesterol. Excessive consumption significantly increases cholesterol intake, leading to elevated blood cholesterol levels and increasing the risk of atherosclerosis and cardiovascular diseases. Taking postpartum women as an example, one egg contains approximately 250 milligrams of cholesterol, while ten eggs contain about 2,500 milligrams.This amount is nearly ten times the recommended daily intake. Furthermore, the fats in eggs are primarily saturated fatty acids. Excessive consumption inevitably causes a sharp rise in serum cholesterol levels, accelerating atherosclerosis and increasing the risk of cardiovascular and cerebrovascular diseases.
Secondly, excessive egg consumption can lead to nutritional excess and obesity. During lactation, a woman's daily caloric requirement is generally around 2800–3000 kcal, with a protein need of 90 grams.Consuming 10 eggs daily equates to 70 grams of protein, 60 grams of fat, and approximately 820 kcal. Combined with the mother's intake of staple foods, chicken, fish, meat, soy products, vegetables, and fruits, daily caloric intake can reach 3500–3800 kcal, with protein and fat intake potentially totaling 120–140 grams.This far exceeds their actual daily nutritional requirements, leading to nutritional excess. The surplus fat accumulates in the body, resulting in obesity.
