Among daily foods, eggs have a high nutritional value and are rich in trace elements, which are beneficial to health in moderation. Children, adolescents and people who are weak after major surgery or physical labor can eat eggs every day according to the situation, but the total intake should be controlled and should not be too much. Generally, normal adults should eat 1-2 eggs per day. Children and adolescents can eat 2-3 eggs a day to supplement their nutrition and promote their development because their bodies are developing and their bodies metabolize nutrients quickly. People who are weak after major surgery and those who work more physically need to supplement their bodies with nutrients, so they can eat 2-3 eggs a day to supplement their nutrition. Eggs are rich in nutrients, and if they cannot be completely consumed, excessive consumption may lead to excess nutrients in the body and gradually lead to obesity, so obese people are advised to eat in moderation. The yolk of an egg contains more cholesterol, and excessive consumption may affect the development of hypercholesterolemia and cardiovascular health. In addition, people with abnormal liver and kidney function are advised to eat eggs under medical supervision to avoid excessive consumption that may lead to discomfort and aggravation of the disease. Patients with cholecystitis can eat eggs, but the yolk needs to be removed because patients with cholecystitis are unable to secrete bile normally and consumption of lipids in the yolk is hindered.
