1, the salt content of marinated eggs is relatively high, and at the same time, compared with boiled eggs, some nutrients have been lost in the process of marinating.
2. Tannic acid will be produced in the process of making salted eggs. Tannic acid is similar to protein in food. Once they meet, solidified substances will be deposited in the body, which seriously affects the human body's absorption and utilization of protein, and the nutritional value of eggs is wasted.
3. If tea is added to the salted eggs, the tannic acid in the tea will affect the absorption of protein. In particular, tea eggs soaked overnight will increase the gastrointestinal burden.
4. Brine will also combine with egg yolk to form iron sulfide, which will affect the body's absorption and utilization of iron and cause anemia symptoms.
5. The production time of marinated eggs is very long, and long-term cooking will lead to excessive denaturation of protein, making it difficult to be absorbed by the human body, and a lot of vitamins will be lost. The most important protein in eggs becomes difficult to be absorbed by the human body because of excessive denaturation.
: ranking of the most nutritious ways to eat eggs:
First place: boiled eggs with shells. The heating temperature is low, and the nutrition is fully preserved.
Second place: Steamed eggs. When the heating temperature is low, the loss of water-soluble vitamins such as riboflavin and lutein is less.
Third place: poached eggs. When the heating temperature is low, there is a little loss of water-soluble vitamins.
Fourth place: fried eggs. When the heating temperature is high, both fat-soluble vitamins and water-soluble vitamins are lost.
Fifth place: scrambled eggs. When the heating temperature is high, all vitamins are lost.
Sixth place: scrambled eggs. High heating temperature leads to more vitamin loss.
