Tianjin reader Ms. Li asked: Recently, the baby came back to say that kindergarten often eat big eggs with two yolks. After listening to it, I felt very insecure. I checked it on the Internet. Some people said that double yolk eggs were stimulated by hormones, and children’s eating would affect their development. Want to ask experts, eat double yolk egg really affect health?

and

Dr. Yun Wuxin of food engineering, Department of agriculture and biology, Purdue University, USA: the “egg production process” of hens is regulated by hormones in their bodies. In a fully developed healthy hen, the laying process is well coordinated, but for those who are just beginning to lay eggs, there may be “abnormal hormone secretion”. For example, after an egg yolk is produced, the “control center” does not receive a signal, so another yolk is produced. Two yolks into the fallopian tube are also wrapped and shaped by protein, and then discharged from the body, resulting in “abnormal” eggs — double yellow eggs. Since the production of

and

is caused by abnormal hormone, can the hen produce double yolk egg by using hormone? In theory,

and

can not be ruled out in theory, but in reality the possibility is very small. On the one hand, Shuanghuang eggs are not much more expensive than ordinary eggs, so we can’t rely on “Shuanghuang” to sell high prices. On the other hand, at present, the use of hormones in the process of chicken breeding is prohibited in all countries of the world, so no one has studied it, nor has it been commercialized.

and

in fact, even if some people actually use hormones to “give birth to” double yellow eggs, hormones affect hens — hormones are only used as signals, which does not mean that hormones will enter the eggs. So it is safe to eat double yolk eggs. In addition, according to the composition analysis of double yellow egg and single yellow egg, although the proportion of some components is slightly different, the difference is not significant. For nutrition, at least, the difference is negligible.

and

some people have raised questions about whether Shuanghuang eggs can hatch two chickens. Experts who specialize in egg research have answered this question. In fact, the possibility is very small due to various conditions. ▲
