I live in the United States, and I'm not moving. But from the standpoint of food safety, the countries in Scandinavia do it better than we do. It's not that they don't have food-poisoning incidents; it's that there are many fewer in proportion to the population.

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.

Unbelievable as it may seem, one-third of all vegetables consumed in the United States come from just three sources: french fries, potato chips, and iceberg lettuce.

Here we have the great irony of modern nutrition: at a time when hundreds of millions of people do not have enough to eat, hundreds of millions more are eating too much and are overweight or obese.

We don't have a farm-to-table food safety system. I keep saying this. It came as a big surprise to the FDA that tomatoes were being grown in the United States, sent to Mexico for packing, and then sent back. I mean, they had no idea that our food chain worked like this.

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.

One can only be in awe of the creativity of chocolate marketers. My take is that if there is a health benefit, it is small.
