The amount of time schools allocate for lunch can be just as important as the food they serve鈥攁nd the 25 minutes to half hour the typical school sets aside is often too short, say the School Nutrition Association and an expert who has studied the issue.
By the time students walk to the cafeteria, maybe run to the bathroom, and wait in line for their food, they often don鈥檛 have enough time to eat all of their meal鈥攅specially the healthy, more fibrous parts鈥攚hich can have long-lasting effects on their academic performance and behavior.
And low-income students who rely on school-provided meals can be especially affected by rushed lunch periods because of the time they spend in line waiting to be served.
But many principals find it hard to balance the time needed for instruction in the classroom with breaks like lunch and recess.
鈥淒ays are really tight anyway,鈥� said Heather Jones, the principal of Trailside Elementary in Anchorage, Alaska. Her school started offering longer lunch periods this year as part of a district pilot program.
鈥淪taff understand that the movement and break time is important,鈥� Jones said. 鈥淏ut students also have to be taught what they need to move up to the next grade.鈥�
The median length of school lunch periods has largely stayed the same over the past decade, according to the School Nutrition Association. But that obscures the problem: With growing student populations, many schools are cycling more students through the cafeteria which means less time for eating, said Gay Anderson, the president of the School Nutrition Association.
Pair that with the fact that federal standards for healthy school lunches have tightened up, and students simply aren鈥檛 left enough time to chew all those fibrous fruits and vegetables, said Anderson, who is also the director of nutrition at the Brandon Valley school district in South Dakota.
鈥淎cross the country we鈥檙e hearing, a lot of those fresh fruits and veggies, which are great to add to our program, need more time to consume,鈥� said Anderson. 鈥淲hen you think about eating an apple versus a canned pear鈥攖hose types of textures, those things make a difference.鈥�
At minimum, students need 20 minutes to sit and eat, said Anderson, excluding time walking to the cafeteria and standing in line. The School Nutrition Association is lobbying the U.S. Department of Education and the U.S. Department of Agriculture to officially recommend just that, citing research on students鈥� eating patterns and nutritional needs.
15 Minutes to Eat?
69传媒 who get less than 20 minutes to eat leave a lot of food uneaten on their trays, said Juliana Cohen, a public health and nutrition professor at Merrimack College and Harvard University鈥檚 school of public health. That鈥檚 what she found in a 2015 study when she . Cohen reckons students need at least 25 minutes of seat time.
Sixty-five percent of the students in the study had less than 20 minutes to eat their lunch and those students consumed significantly less of their entrees, vegetables, and milk compared to students who had at least 25 minutes to eat. They ate 13 percent less of their entrees, 12 percent less of their vegetables, and drank 10 percent less of their milk, Cohen found. 69传媒 were also much less likely to select fruit for their meal.
Seventeen percent of students in Cohen鈥檚 study had even less time鈥攗nder 15 minutes鈥攖o eat.
Too-short lunch periods disproportionately harm low-income students for whom school lunch may be their most reliable and hearty meal of the day.
鈥淭hey are more likely to receive a school meal and they will be standing in that line,鈥� said Cohen. 鈥淎nd they also rely on school meals for half of their daily calorie intake. They especially need that time to eat their food.鈥�
But when it comes to setting the daily schedule, lunch time is frequently whittled away in order to provide more instructional time. Experts like Anderson and Cohen said that principals shouldn鈥檛 view lunch and instructional time as an either-or proposition鈥攍unch doesn鈥檛 take away from academics, it enhances them.
鈥淩esearch suggests that when students eat healthier food it is associated with improved executive functioning鈥攚orking memory, impulse control, everything we think of when we think of making a student successful,鈥� said Cohen.
Proper nutrition helps prepare students for test-taking, said Anderson, and also means fewer students visiting the school nurse for ailments caused by hunger such as headaches.
鈥淲e have to work together on this as a whole community,鈥� Anderson said. 鈥淭he nutrition piece is a very valuable piece in getting the child educated.鈥�
Balancing Breaks With Instruction
At Trailside Elementary, it鈥檚 too early to tell what the effects of the slightly longer lunch periods will be, but so far Jones has received positive feedback from students, teachers, and especially parents. The Anchorage school district started the pilot program just this year鈥攊n response to a petition from parents.
Lunch period was increased from 20 to 25 minutes, while recess time was upped from 20 to 30 minutes. The five minutes Trailside allocated for transitioning from recess to lunch remained the same.
Participating in the pilot program was voluntary, and Jones was eager to give it a try.
Even though her teachers appreciate the value of giving students more time to run around and eat, losing 15 minutes of instruction time leaves them feeling a bit squeezed.
鈥淓specially those older kids, it鈥檚 hard to get the academics in,鈥� she said. 鈥淪omething has to give, because we didn鈥檛 expand the school day.鈥�
So, what can schools do?
While there are no federal guidelines for how long schools should give for lunch time, there are best practices.
Anderson suggests having more grab-and go-options鈥攕o students can just walk up and grab, say, a pre-packaged salad with chicken, an apple, and a carton of milk. She also suggests letting students eat in their classroom, so precious time isn鈥檛 spent walking to the cafeteria, waiting in line, and finding a seat.
In Houston鈥檚 school district, the director of nutrition began experimenting with 鈥渇amily style鈥� lunch service in classrooms, where students and teachers eat together. The in-classroom dining gives students as much as 30 minutes to eat by eliminating the walk to the cafeteria and wait time in line. In one elementary school that piloted the approach in the youngest grades, the principal was able to move the lunch period for preschool, kindergarten, and 1st grade from 10:30 to noon.
Other strategies schools can consider to get students to the tables to eat more quickly are adding additional lines and automated point-of-sale services where they simply have to swipe a card to pay for their food, said Cohen.
There are other scheduling decisions schools can make to ensure students eat more of their meals, said Cohen, such has not scheduling lunch before 11 a.m. and holding recess before lunch鈥攏ot after.
鈥淚t allows students to focus on their meal and not be rushing through their school meal because there鈥檚 an incentive to go out and play faster,鈥� she said.
