What Happens When You Eat Expired Food?
You Might Experience Nothing At All
So, chances are that you might experience nothing at all when you eat expired food, except a yucky taste. However, it is not a good idea to continue eating expired food daily.
One of the interesting facts is that no matter how long a food is frozen, you can safely eat it.(2) Food poisoning doesn’t grow in the freezer, though the food might become dry, and might not taste best. Packaged foods like pasta, or cereals also remain safe past the “best by date”.
Moreover, you won’t fall ill with pasteurized foods in general, though they might have a funky taste or smell. FDA notes that all harmful bacteria are killed in the process of pasteurization.(3)
You Might Be Affected By Food Poisoning
When you eat food after its expiry date and if the food is spoiled, you might develop certain symptoms of food poisoning. Stomach cramps, fever, chills, nausea, diarrhea and vomiting are some of the symptoms that you might experience with food poisoning.

You Might Eat Something That Has Lost Its Nutritional Value
Foods after their expiration date lose their quality and develop a stale or poor taste. However, the biggest thing is that they might also lose their nutritional value.
A study that was conducted on maximizing the nutritional value of vegetables and fruits had also mentioned that nutritional value gets lost between the time of harvest, the time for which they are displayed at the store, and the time the consumer keeps them stored before consumption.(5)
Sometimes Eating Expired Food Can Result In Death
It must be kept noted that in extreme conditions, a person might die from eating foods past their expiration date. This is because some diseases like Listeria can be hazardous, especially for people with weakened immune system (in the case of the elderly, newborns, or unhealthy or sick people)
