The key dietary messages are stunningly simple: Eat less, move more, eat more fruits and vegetables, and don't eat too much junk food. It's no more complicated than that.

Eat less, move more, eat lots of fruits and vegetables, go easy on junk foods.

Many countries have food safety systems from farm to table. Everybody involved in the food supply is required to follow standard food safety procedures. You would think that everyone involved with food would not want people to get sick from it.

We don't really have any that protect the food supply from farm to table. We have a food safety system that's piecemeal, largely divided between two agencies that don't talk to each other very much. Neither agency can enforce regulations from the farm to the table.

BASICS OF DIET AND HEALTH The basic principles of good diets are so simple that I can summarize them in just ten words: eat less, move more, eat lots of fruits and vegetables. For additional clarification, a five-word modifier helps: go easy on junk foods.
