The growth of the American food industry will always bump up against this troublesome biological fact: Try as we might, each of us can eat only about fifteen hundred pounds of food a year.

What this means for the food industry is that its natural rate of growth is somewhere around 1 percent per year—1 percent being the annual growth rate of the American population. The problem is that Wall Street won’t tolerate such an anemic rate of growth.
