Egg tea is a nutritious drink in my mother's hometown. It is not only easy to digest, but also nutritious and delicious. It is said that there are many longevity secrets for long-lived elderly people there, which is to drink egg tea all year round, especially after getting up in the morning, to drink a bowl of fragrant and hot egg tea to keep healthy. <br />Black-chicken eggs are rich in a variety of trace elements, the organic calcium content is 6 times that of ordinary eggs, and the cholesterol is extremely low, which is one-third of that of ordinary eggs. Black-chicken eggs can promote children's growth and development, enhance memory, treat children's appetite for anorexia, food abandonment, low immunity caused by zinc deficiency, and nutritional nourishment for pregnant women, as well as cardiovascular diseases and thyroid tumors in middle-aged and elderly people.
