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.

The problem with nutrient-by-nutrient nutrition science is that it takes the nutrient out the context of the food, the food out of the context of the diet, and the diet out of the context of the lifestyle.

One way in which we can encourage the Chinese government to take more vigorous action to control food safety in their country is by just saying we're not going to buy Chinese foods until they get their system cleaned up. Admittedly it's a difficult system to get under control because an astonishing percentage - maybe 80 percent - of the foods in China are produced in small backyard operations.

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.

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.

Consumers have to understand that the purpose of these claims is to get them to buy the product.

Meat is produced under HACCP plans. Meat and poultry are required to be produced under standard food safety plans and they have been since the mid-'90s, and there are now fewer problems with meat than there used to be. That's on the USDA's side.
