dave submitted a story in the Chicago Tribune about how a study McDonald's did showed their fries had more trans fat than they had been stating on the label.

Correcting a labeling error, the hamburger giant acknowledged Wednesday that the trans fat content in an order of its large fries is one-third higher than previously stated, containing 8 grams of the heart-endangering fat instead of the 6 grams listed on brochures and McDonald's Web site. In addition, the Oak Brook-based company said, the total fat content of its large fries is 20 percent higher, 30 grams rather than the 25 grams listed, while total calories rose to 570 from 520.

It was a black eye for McDonald's, which in October trumpeted its initiative to print nutritional data on its packages to help consumers make informed choices about what to eat. The packaging is being rolled out in Turin, Italy, the site of the Winter Olympics.

"It is uncertain whether the testing lab goofed, or they had so few samples that some guy in Peoria left the fries in the fryer too long. But 2 grams of trans fat is quite a big difference," he [Michael Jacobson, executive director of the Center for Science in the Public Interest, a food and nutrition lobbying group] said.
