Food is expensive today – and it was expensive a hundred years ago. Here is what someone a hundred years ago said about how they minimized their food costs:
We save on food costs. Twenty-five percent of the known incomes, allows $660 a year for food. I allow $540 or $45 a month, for a family of four. It means a very plain table. It means, too, that food costs are lessened by our flock of 12 to 15 chickens which returns 50% above its yearly cost, and by a garden from which I can vegetables and fruits. We pay in labor for part of our food – caring for the garden and the chickens.
