TRANS FATS: Levels of artery-clogging trans fat in fries and chicken at McDonald’s and KFC are higher in the U.S. than in many other countries, Danish researchers report.

THE REASON: Many restaurants are still using partially hydrogenated vegetable oil for frying.

THE DANGER: Just 5 grams of trans fat a day raise the risk of heart disease 25 percent – and a large order of fries and nuggets in New York City can contain double that.

THE CHOICE: McDonald’s and KFC say the oil used reflects taste preferences from country to country.
