According to relevant data, the contents of protein, fat and carbohydrate in eggs and quail eggs are basically the same. There are four main differences in nutritional components between eggs and quail eggs: (1) The content of vitamin A in eggs is more than four times that of quail eggs; (2) The content of B vitamins in quail eggs is more than that in eggs, especially the content of vitamin B2 is twice that of eggs, which is an auxiliary enzyme for biochemical activities and can promote growth and development; (3) The cholesterol content in quail eggs is higher than that in eggs; (4) The content of lecithin in quail eggs is higher than that in eggs. Quail eggs and eggs have their own advantages in nutritional components. According to these nutrients, different people can treat eggs differently. For example, babies can choose to eat quail eggs, because the content of lecithin in quail eggs with the same weight is higher. Lecithin is an essential nutrient for children's brain development and contributes to children's brain development. The baby should also eat boiled eggs, take the yolk from the boiled eggs and make it with boiling water, because it is easy to digest and absorb. If children eat quail eggs, it is advisable to eat 3 ~ 4 quail eggs every day (3 ~ 4 quail eggs are equivalent to one egg), while primary and secondary school students have a heavy learning burden and use more eyes, so they can choose to eat eggs, mainly because the vitamin A content in eggs is high, which is beneficial to vision development. Because the cholesterol content of quail eggs is higher than that of eggs, it is recommended that the elderly eat eggs.
