In India, the government offered a bounty on rats. The intention was to eradicate a noxious pest. One unanticipated result was the establishment of rat farms, where rats were bred and harvested for the bounty. In Florida, a worker at a dog kennel noticed lots of snakes on the premises. He systematically killed them all. Then the rat population increased dramatically.

These are examples of the Law of Unintended Consequences, which states that any human action--whether or not it produces the desired result--is likely to produce an entirely different result (possibly in conflict with the original intention.) Typically, such results are completely unexpected. Often, they are just as completely undesired.

Let's review some of the changes which the Standard American Diet has pioneered: American food has been stripped of virtually all of its essential nutrients. Sugar and fat seem to be the major ingredients in virtually every American food. (About 45 percent of the caloric value of our diet comes from fat, and we use about 100 pounds of sugar per person per year.) Our consumption of hydrogenated fat is the highest in the world. We have virtually eliminated vegetables from our diet. We have drastically reduced the variety of foodstuffs we eat. We no longer rotate our diet with the change of the seasons. We consume about six pounds of synthetic food additives per person per year. Our widespread use of denatured flours, refined sugars, devitalized fats and oils, and synthetic food additives has been in effect for about one hundred years. Speaking in individual terms, this is a long time. In terms of the human race, it is a very short time. These dietary changes are quite radical when compared to human dietary tradition. And they don't seem to be good for you, either. As the American diet has changed, so has our health. Americans now lead the world in obesity, diabetes and heart disease. In fact, consumption of the Standard American Diet constitutes a chronic metabolic insult. Ours is the only civilization in history which has single-handedly managed to break its food.

How did this come to pass? We did it ourselves. There doesn't seem to have been any kind of evil conspiracy, or divine intervention. It just kind of happened, as the result of many un-coordinated, short-sighted decisions--made with the very best of intentions by people who were only trying to improve the lot of suffering humanity.

In June, 2002 the Journal of the American Medical Association recommended that every American use a daily multi-nutrient supplement to address the issue of deficient diets. What makes this unusual is the fact that mainstream medicine has fought tooth and nail with the forces of vitamin and mineral supplementation for decades. Previously, supplementation had been characterized by them as a mostly harmless waste of money.

Perhaps there may be some hope, after all.
