Fast food chains have tried for years to appeal to customers who care about their health. They have added lighter food to their menus, such as salads and yogurt. Of course, the lighter food goes with the usual burgers, fried chicken and shakes.
Menus have changed over the past three decades. According to a recent study, fast food menus are less healthy than they were 30 years ago. The study suggests the problem is getting worse. The fat, salt content and size of fast food meals are the problem. They are often the reason for the rising obesity (肥胖) rate among adults in the United States. The researchers found that the average main dish weighed more in 2016 than in 1986. It also had more calories and more sodium (钠). One expert said, "The restaurants have not done enough. The big picture is that there have been some positive changes, but they are small. Overall, the changes have gotten worse. "
The average fast food dessert had more calories in 2016. It also weighed more than the average fast food dessert thirty years earlier. Restaurants are counting on bigger sundaes and cookies to increase the amount spent on each order. For example, McDonald's recently introduced "donut sticks" dusted with sugar. Six sticks have 280 calories. But you can also order 12 sticks for less than the cost of two single orders.
The researchers found that, over the 30 years, there were more calories in items like chips, soup, and French fries. Sodium content rose even though portion(一份) size did not grow much. When consumed together as a single meal, the study found that the average main dish and side order account for nearly 40 percent of a 2000-calory daily diet.
