The experts at the FDA have said that the average adult will consume the following amounts of fresh food per year.
Meat - 150 to 200 pounds per year
Flour - 200 to 300 pounds
Sugar or honey - 60 pounds
Fats or Oils - 60 pounds
Salt - 5 pounds
Powdered Milk - 75 pounds
Vegetables and Fruits - 600 to 700 pounds
Water - 375 gallons
The figures above are nice guidelines, but they need to be considered from the technical angle of preserved foods rather than fresh foods.
