McDonald's recently announced that its French fries contain a third more trans fats than was previously thought.
Each serving of fries contains 8 grams of trans fat, rather than 6, and the total fat content is 30 grams rather than 25.
As Little as Possible
Trans fats are believed to cause cholesterol problems and heart disease. Dietary guidelines issued by the U.S. government advise people to consume as little trans fat as possible.
Changing the Taste
In countries such as Australia, Denmark, and Israel, McDonald's cooks its fries in canola oil, which contains no trans fats. However, the company is reluctant to make the switch in America, for fear of changing the taste of its fries.
