The increasing popularity of American-style fast food restaurants in Asia is taking a toll on their citizens' health.
Researchers at the University of Minnesota studied surveys filled out by more than 50,000 Chinese adults living in Singapore.
They found those who ate an American diet twice a week were more than 50 percent more likely to die of heart disease, and 25 percent more likely to develop diabetes.
The risk was significantly higher for those who ate fast food four or more times a week.
At the start of the study, researchers used in-person interviews and a specially designed food frequency questionnaire tailored for this population assessing 165 food items commonly consumed. the questionnaire inquired on six fast food items: hamburgers and cheeseburgers, french fries, pizza, deep fried chicken, hot dogs, and other fast food sandwiches.
Study participants were 45- to 74-years-old.
