Count Your Calories (Production Calories, That Is)
Every food product you purchase has two caloric values: the amount of energy you receive from it (the value printed on the side of the package) and the amount of energy required to produce it. In today’s food industry the second caloric value comes from a variety of sources: the sun, the human energy involved in production, and the fossil fuels that drive the machinery used in the farming process and power the production of chemicals.
Some of the statistics are hard to swallow: the modern production and distribution system spends 10-15 calories for every calorie it produces; the United States expends three times the energy per person for food that developing countries use per person for all energy activities.
To reduce production calories, try to buy as few processed foods as possible. Two pounds of flour requires less than 500 calories of energy for processing; the comparable amount of soda requires
over 1,400 calories; chocolate requires over 18,500 calories.
