As many Americans look to eat healthier, plenty of major QSRs have taken note. Research published this week by the University of Minnesota School of Public Health found that five major chains – McDonald’s, Burger King, Wendy’s, Jack in the Box and Dairy Queen – have significantly decreased the amount of trans fats used in their cooking oils.
Additionally, they aren’t raising levels of saturated fat to compensate. The study catalogued the nutritional values of more than 18,000 menu items, specifically measuring trans fat and saturated fat levels in French fries.
According to the study, McDonald’s, Burger King and Wendy’s decreased the trans and saturated fatty acid composition of their French fries between 1997 and 2008. Additionally, saturated fats either remained steady or decreased. Information from Jack in the Box and Dairy Queen showed a decrease in both trans and saturated fatty acid composition since 2008.
Brands not included in the study that moved away from trans fats beginning in 2007 include Carl’s Jr. and Hardee’s, Popeyes, Dunkin' Donuts and KFC.
