鸡蛋营养丰富,是婴幼儿良好的辅助食品。但吃得过多,反会危害健康。鸡蛋的蛋清里含有胰蛋白酶抑制物和抗生素蛋白。胰蛋白酶抑制物能使肠道内的消化酶(特别是胰蛋白酶)受到抑制,会引起消化不良。抗生素蛋白能在肠道里与生物素(即维生素H)结合,从而阻碍生物素被肠道吸收。婴幼儿过多吃鸡蛋白会导致生物素缺乏症。生物素是对身体十分重要的羧酶的辅酶,有着广泛的生理功能,缺乏时会引起皮肤红斑、脱发、烦躁或嗜睡、运动失调、发育迟缓等一系列症状和体征。临床上已有长期篇食鸡蛋白引起生物素缺乏症的报导。动物实验也已证实,长期用鸡蛋白喂养的小鼠会发生脱毛、运动失调、听 Rich nutrition of eggs, infants and young children is a good supplementary food. But eating too much, anti-will endanger the health. Egg white egg contains trypsin inhibitor and antibiotic protein. Trypsin inhibitors can make the intestinal digestive enzymes (especially trypsin) is inhibited, can cause indigestion. Antibiotics bind to biotin (ie, vitamin H) in the intestine, hindering intestinal absorption of biotin. Too many babies eat chicken egg white can lead to biotin deficiency. Biotin is a carotenoid coenzyme that is very important to the body. It has a wide range of physiological functions. It causes a series of symptoms and signs such as skin erythema, alopecia, irritability or drowsiness, dyskinesia and retardation. Clinically, there have been reports of biotin deficiency caused by chronic eating chicken protein. Animal experiments have also confirmed that long-term use of egg white mice fed hair loss, exercise disorders, hearing
