During World War I food in the U.S. was very expensive, and people worried about food shortages. Here’s excerpts of what Harvey Wiley, a popular food expert who led the laboratories at the Good Housekeeping Institute, had to say:
The victory in this war will be won by those nations which have the best and most abundant supply of food. Bread is more important than munitions. The nation that is hungry will first be ready to yield. We must see to it that none of the Allies is put in such a position. To this end everything that can be done to awaken the American people to their responsibility must be done.
We must stop wasting food in our kitchens and on our tables, and we must conserve the whole of the food product that is edible.
Our people must be taught how to eat in these times of stress. The teachers of home economics and domestic science throughout the country should be mobilized to carry messages to the people. The welfare of the nation is at stake. The success of our Allies is in the balance. It seems strange to speak of an army of diet experts, but such an army is just as important as one carrying modern rifles and sharp bayonets.
