If you thought that McDonalds' in USA serves the same fries as the outlet in Paris then take out time and think!
According to a study by three Danish doctors, fat levels varied and also levels of unsaturated fatty acid known as "trans fat" in foods purchased at McDonald's Corp and KFC fast food chains in 20 countries.
According to the staggering research published in this week's New England Journal of Medicine, one large nuggets and fries meal, has trans fat varied less than 1 gram in Denmark to more than 10 grams in New York City.
Steen Stender, author of the study, said, "The results show that industrially produced trans fat can be eliminated without notable increases in the cost of foods or reduction in the quality or availability of foods,"
McDonald's conceded and announced in February that it had understated the amount of fat and calories in its french fries. It had originally said its large serving of fries had 6 grams of trans fat. The company said the correct number was now 8.
