The first time is cooked, and the second time is to break the egg skin, add tea leaves and other accessories, and then cook again, so tea eggs must be cooked. However, tea contains biological acid and alkali components, which will penetrate into the eggs when cooked and combine with the iron in the eggs; this combination is highly irritating to the stomach, and over time, it will affect the digestion and absorption of nutrients, which is not good for human health.

　　Some people also like to eat half-cooked eggs (the yolk is semi-liquid) and cannot be eaten overnight. Even if they are cooked the second time, do not eat them.

　　2. Can I drink overnight tea?

Moreover, if water is repeatedly boiled for too long or for more than 24 hours, the nitrite content will increase significantly.

　　Tremella soup is an advanced nutritional supplement, but overnight, the nutrients will be reduced and harmful components will be produced. Because both the Tremella fuciformis cultivated indoors and the Tremella fuciformis cultivated outdoors contain more nitrates, if they are left for a long time after being cooked, the nitrates will be reduced to nitrites under the decomposition of bacteria. When people drink this soup, nitrite naturally enters the blood circulation. The red blood cells in the blood contain hemoglobin, which can carry a large amount of oxygen for the body's needs. However, nitrous acid has the opposite effect, causing normal hemoglobin in the human body to oxidize into methemoglobin, losing the ability to carry oxygen, causing the human body to lack normal hematopoietic function!
