It is best for healthy people to eat an egg every morning. If you eat too much, you can't absorb it. But from the point of view of nutrition, in order to ensure a balanced diet, meet the needs of the body, and not be overnourished, under normal circumstances, it is better for the elderly to eat 1 ~ 2 capsules a day. For young and middle-aged people, it is more appropriate to eat 2 eggs a day if they are engaged in mental or light physical labor; Those who are engaged in heavy physical labor and take more nutrients can eat 2 ~ 3 eggs a day; Teenagers and children can take 2 ~ 3 capsules a day because of their long body and fast metabolism. Pregnant women, lying-in women, weak nursing mothers and patients recovering from major surgery can eat 3-4 eggs a day, but not more, because they need to increase the quality of protein.
