The standard four food groups are based on American agricultural lobbies. Why do we have a milk group? Because we have a National Dairy Council. Why do we have a meat group? Because we have an extremely powerful meat lobby.

What we know about diets hasn't changed. It still makes sense to eat lots of fruits and vegetables, balance calories from other foods, and keep calories under control. That, however, does not make front-page news.

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.

The chef has kids complaining to their parents the food they get in school is better than what they get at home. He's turned this group of kids into curious, adventurous eaters.

Food safety oversight is largely, but not exclusively, divided between two agencies, the FDA and the USDA. The USDA mostly oversees meat and poultry; the FDA mostly handles everything else, including pet food and animal feed. Although this division of responsibility means that the FDA is responsible for 80% of the food supply, it only gets 20% of the federal budget for this purpose. In contrast, the USDA gets 80% of the budget for 20% of the foods. This uneven distribution is the result of a little history and a lot of politics.

I would require every producer of food to follow and have enforced a standard safety plan. We know how to produce safe food. It has a horrible name; it's called HACCP - Hazard Analysis and Critical Control Point - and this was a food safety system that was developed for NASA so that astronauts wouldn't get sick in outer space. If you just think about what it might be like to have food poison under conditions of zero gravity, you don't even want to think about it.

The pet food recall, which was after all just about pets, and treated as if it were an inconsequential matter, was an absolute forerunner of what's going on in China, where 50,000 infants have been sickened because of a contaminated infant formula. So these things are all closely related. You cannot separate the food supply for pets, farm animals, and people, and you cannot separate problems in one area of a country from problems in another area.
