Canned food cans are created in such a way that they can fully maintain their nutrients for dozens of years. An innate characteristic is based on the constitution of the container and the conservation of the food in it that has nothing to do with expiration dates. 

According to a recent study by Harvard University, the expiration date is framed as a preventive measure to minimize poisoning. However, this term has nothing to do with the moment with the toxicity of the product but with the moment in which the food begins to lose its properties.

According to the latest studies carried out by the US Food and Drug Administration, this type of food can be kept in good condition for up to approximately 100 years. Of course, before ingesting any type of substance, it is best to make sure if the container has a leak or a point where its integrity may have been damaged. In that case, ingestion would be harmful to our bodies.

In 2012, a reputed German pharmacist found a can of butter in his home dating from 1948. As a good professional, he handed the can over to his country’s health authorities to determine its status. To the pharmacist’s surprise, the medical team decreed that this product was perfectly suitable for consumption; it had only lost a little flavor and smell differently. 

The same thing happened with some cans found on a sunken steamship in the Missouri River. Some containers that contained honey, tomatoes, and oysters that after an exhaustive analysis had only changed their appearance but retained most of the nutritional properties, except vitamin A and C.

It seems surprising, but the products built into the cans can stay active much longer than we imagined. Without a doubt, the best remedy to survive in the event of a catastrophe!
