In 1919, people felt a bit smug about how easy it was to have sufficient food during the long, cold winter months; and, were thankful that they didn’t live back in the “old” days when it was often challenging for people to have access to sufficient food during the winter.
I recently came across an article in a 1919 magazine that went so far as to claim modern cities were able to develop as a result of the availability of canned foods.
With the enormous increase in size and number of cities, during the past century, the problem of winter sustenance has assumed tremendous proportions. It has been met by elevating to the first place of importance a method of food preservation that had always been of least value – exclusion of air.
The tin can and the glass jar are inventions which made this possible, and without them, modern city life, if not actually out of the question, would have been vastly more difficult. If one will but try to conceive what his mid-winter menu would be like, stripped of all the articles that come to him in glass or tin, he will hardly question any estimate which we may feel inclined to make as to the importance of canned foods in the civilization of today.
With all due allowance for their undoubted benefits, however, the tin can and the glass jar have not shown themselves altogether free from reproach. They must shoulder full responsibility for the growth of the factory system of food production, which, at its best, fall short of being an unqualified boon to the consumer.
