Expired mooncakes should not be consumed, as they, like all food, have an expiration date. It is safer to eat mooncakes within the specified shelf life. Once this period has passed, mooncakes may spoil due to oxidation of fats or contamination by bacteria or mold, thus threatening food safety and causing gastrointestinal discomfort, including symptoms such as diarrhea, abdominal pain, and vomiting. If a large amount of expired mooncakes is accidentally consumed and the reaction is severe, medical attention should be sought immediately.
Mooncakes themselves are difficult to digest due to their high sugar and oil content, so they should be consumed in moderation to avoid placing a burden on the gastrointestinal system. The best times to eat them are in the morning or at noon to prevent digestive issues from affecting sleep quality. Therefore, while enjoying the deliciousness of mooncakes, it is essential to check their expiration date and control the amount consumed.
