Tea contains biological acid and alkali components, which will penetrate into eggs after cooking and combine with iron in eggs; This combination is very irritating to the stomach. Over time, it will affect the digestion and absorption of nutrients, which is not conducive to human health. Eat less every time, especially at night. For health, eat one tea egg at a time! Reason: When cooking eggs with tea leaves, people are used to putting a lot of tea leaves to soak the eggs. Tea with high concentration will produce more tannins, similar to protein in food. Once they meet, solidified substances will be deposited in the body, which will seriously affect the human body's absorption and utilization of protein, and the nutritional value of eggs will be wasted. Tea alkaloids in tea will also combine with egg yolk to form iron sulfide, which will affect the absorption and utilization of iron by human body and cause anemia symptoms. In addition, tea contains biological acid-base components, which will penetrate into eggs after cooking and combine with iron in eggs; This combination is very irritating to the stomach. Over time, it will affect the digestion and absorption of nutrients, which is not conducive to human health. For the above reasons, it is not appropriate to cook eggs with tea at ordinary times. Solution: Eat once in a while, no more than one tea egg at a time.
