Eggs can be eaten overnight without spoilage, but not if spoilage occurs. Eggs are a common food, which is rich in protein, and can be eaten appropriately to meet the body’s need for protein. If the eggs are not eaten on the day, it is not possible to generalize whether they can be eaten after the night. If the eggs are not spoiled, you can continue to eat them and they will not cause any adverse effects on the human body. If the eggs are spoiled, they should not be consumed, otherwise gastrointestinal symptoms such as nausea, vomiting, abdominal pain, diarrhea, etc., and in serious cases, food poisoning may occur. If conditions permit, it is recommended to finish the food on the same day and eat fresh food on the next day to avoid prolonged intake of large quantities of overnight food.
