Nutrition, food safety, and farm policy.

Another food revolution has been waiting in the wings, while the various agricultural revolutions were creating an urban nation and blessing it with abundant food. The agricultural revolutions modernized the production of food. The next revolution may change what Americans choose to eat, making use of the wide choices now possible among both natural and manufactured foods. The benefits of this diet revolution will include generous reductions in health-care costs and food budgets. It will also contribute in a major way to the conservation of soil, energy, and other natural resources. The diet revolution will leave Americans healthier and wealthier, as did the agricultural revolutions.
