When boiling eggs, open the lid and let the water bubble slightly. At about 60℃-87℃, the egg will not break.

Protein in eggs can be cooked at 60℃-87℃ without high temperature.

Compared with porridge, bread and other foods, protein's amino acid composition in eggs is better, its essential amino acid composition is basically similar to that of human body, and its biological value is also the best among all foods. In addition, the absorption and utilization rate of protein in eggs is higher than that in porridge and bread.

Step 4 be alert. Eggs are rich in tyrosine, which plays an important role in improving people's alertness, thus making people react faster.
