According to a new study, it has been found that the fries and chicken nuggets served at McDonald’s and KFC restaurants contains trans fat, which is never the // same and varies from country to country.
The study, published by Steen Stender and colleagues in the April 13 issue of The New England Journal of Medicine found that "the content of trans fatty acids varied from less than 1 gram in Denmark and Germany, to 10 grams in New York (McDonald's) and 24 grams in Hungary (KFC)", reports foodconsumer.org.
For the study, Stender and colleagues ordered a large serving of French fries and chicken nuggets at McDonald's or KFC restaurants in 43 US and international locations between November 2004 and September 2005. Then, they analyzed the trans fat content in the foods they collected.
The three locations where highest amounts of trans fats used in McDonald's items are New York, Peru and Atlanta, researchers report. But how much trans fat McDonald's use in other US cities remains unknown.
In comparison, KFC uses highest amounts of trans fat in Hungary, Poland, and Peru, according to the study. New York ranked eighth while how much trans fat is used in other US cities is unknown.
The researchers write that the oils used in McDonald's restaurants in the US and Peru contained 23 percent and 24 percent of trans fats, respectively, compared with 10 percent trans fat in the frying oils used for French fries in many European countries.
In some countries such as Spain and Denmark, McDonald's uses oils with 5 percent and 1 percent trans fat, respectively. In France, MacDonald's and KFC use frying oils with 15 percent and 8 percent trans fats respectively, to fry French fries.
Trans fat or partially hydrogenated oil is used to fry chicken nuggets or French fries largely because the oil is more stable and can be used for a longer time compared with ordinary vegetable oils. Trans fat may also give certPage: 1 2 3 Related medicine news :1
