Lunch is an important meal for growing students .In the US, schools a 1 the country are changing their menus to serve h2 food ,but most schools give students little time to eat .

A new survey by the School Nutrition Association of the US s3 primary school students  have about 25 minutes for lunch and middle school and high school students about 30 minutes. That includes the time students need to go to the restroom, wash their hands, walk to the cafeteria and stand in l 4 or their meals.

In f 5 , students may have only about 10 to 15 minutes left to eat their meals, but they need at l 6  20,the association says.

Many students feel r 7 at lunchtime.Jamie Taylor.a 15-year-old student at an Oklahoma middle school,thinks that healthy foods often takes m8  time to eat.

“For example,it takes more time to c9  a whole apple than some applesauce[苹果酱]，and eating a salad takes longer than eating a cheeseburger or chicken nuggets”.Taylor said.”you always have to rush to the cafeteria and rush to eat every time.”

Besides,some kids eat their favorite foods first, and if they run out of time, those vegetables may get left behind..

“It has made it impossible to have the j10 of sitting down and enjoying a lunch,”says Helen Phillips,president of the Association.

Phillips thinks that,nowadays,the attiude is to make students sit down and eat and get it over with quickly.”I don’t know if there is a perfect way,but we will try to make it as perfect as we can.”Phillips said.
