The trans fat label has been an enormous incentive for food companies to take trans fat out of their products.

The Centers for Disease Control says that there are 76 million cases of food poisoning in the United States every year, 350,000 hospitalizations, and 5,000 deaths. Is that a lot or a little? Well, it depends on how you look at it.

When you have a food safety system that's voluntary and not mandatory, you're in a situation in which everybody wants everybody else to go first. So as a normal course of doing business, food companies cut corners and don't want to take the kind of trouble and the kind of testing and the kind of careful procedures that are required to produce the safe food because they don't have to.

To speak only of food inspections: the United States currently imports 80% of its seafood, 32% of its fruits and nuts, 13% of its vegetables, and 10% of its meats. In 2007, these foods arrived in 25,000 shipments a day from about 100 countries. The FDA was able to inspect about 1% of these shipments, down from 8% in 1992. In contrast, the USDA is able to inspect 16% of the foods under its purview. By one assessment, the FDA has become so short-staffed that it would take the agency 1,900 years to inspect every foreign plant that exports food to the United States.

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.

You need to identify the steps at which contamination can occur - those are the critical control points. You take steps to make sure that that doesn't happen. And you monitor and evaluate and test to make sure that your system is working properly. And if it's done diligently and done faithfully and monitored carefully, then they're producing safe food. And no astronaut of which I'm aware has ever gotten food poisoning in outer space.

If we have a food supply that we can't trust, that has enormous implications for the way we view government, for the way we trust business, and for our international trade relations.
