In general, healthy adults eat 1-2 eggs a day; It is better for the elderly to eat one every day; It is more appropriate for mental workers to eat two eggs a day; Pregnant women, lying-in women, lactating women and the weak can eat 2-3 eggs a day, not more. Boiled eggs are the best way to eat, but they should not be overcooked.

In daily life, eggs are the most common nutritious food, and it is often thought that they have the functions of strengthening the brain, improving intelligence, protecting the liver, preventing arteriosclerosis, preventing cancer and delaying aging. However, a study conducted by scientists for as long as 14 years found that compared with their peers, women who eat 1 or more eggs a day have a higher mortality rate than women who eat only one or two eggs a week. Some scholars selected 9,300 men and women as the research objects, all of whom had received a lifestyle questionnaire in 1980, including what different foods they often ate. According to the follow-up survey, the mortality rate of women who eat one egg a day is 22% higher than that of women who only eat one or two eggs a week (regardless of age, smoking habits and weight), and the mortality rate of women who eat two or more eggs a day is higher, but the number of these women is small.

Women who eat the most eggs are also more likely to die from heart disease and stroke, although statistically speaking, the relationship between them is not very close. Scholars believe that this may also be related to the fact that women rarely die from these two diseases.

Nutritionists believe that eggs should be boiled in boiling water for 5-7 minutes. When fried eggs are over-aged, the edges will be burnt, and the high molecular weight protein contained in egg white will become low molecular weight amino acids, which can often form toxic chemicals at high temperature.
