How Much Food do Kids Throw Away at School?

Kids eat what they want and throw the rest away

Experts say they can’t be sure kids will actually eat the increased portions of fruits, vegetables and whole grains called for in new USDA school meal guidelines. And now the Chicago Tribune reports that kids in Chicago are turning up their noses at healthier food. At one school, the Trib measured and found that hundreds of pounds of food were being tossed in the trash ever day at just one school. That included whole apples, oranges and bananas, entire cartons of milk, unopened boxes of cereal.

I observe the same phenomenon every day at the elementary school my daughter attends here in the District of Columbia. I usually stop in twice a day–breakfast and lunch–and photograph the food while watching to see what the kids are eating–or not eating. What I see routinely are kids rejecting “healthier” foods, especially vegetables and whole grains.

Recently, for instance, I was surprised to see kids lining up for seconds at lunch before some kids had even been served their first portions. Turns out what they wanted were the meatballs that came with their whole wheat spaghetti. Otherwise, the pasta along with a wonderful green been salad, a side of corn and a whole wheat roll all went into the garbage can.

So called “plate waste” is nothing new to officials at the U.S. Department of Agriculture, which administers the school lunch program. In fact, schools use an “offer versus served” option in the meal line designed to cut down on food waste. In order to qualify for federal reimbursements, schools using this option must offer at least five items representing the various food groups, along with milk. But kids are only required to select three of the items. The program is mandatory in upper grades, and optional in elementary schools.

The USDA has studied food waste in school cafeterias, but not since 2002. That study [PDF] did not collect new data, but surveyed the existing studies researchers were able to locate. Their conclusions:

* Food waste comprises about 12 percent of total calories selected by students in the meal line, as reported in the USDA’s 1991-92 School Nutrition Dietary Assessment. This is said to be in the “normal” range. But some studies have found the figure ranging as high as 37 percent.

* Food items most frequently thrown away uneaten are salad, vegetables and fruit.

* Girls throw away more food than boys.

* Younger kids trash more food that older kids.

* The value of wasted food is probably around $1 billion annually.

Researchers found that some strategies, such as allowing kids to create their own plates at “food bars,” help cut down on food waste. But food bars are difficult to implement because of the additional equipment involved. Plus, after the kids make their selections, they then must pass a cash register or “point of sale” station so that an adult can confirm that they have taken the correct foods in the required portion sizes. Imagine the traffic congestion this can create in the cafeteria.

Rescheduling lunch so that it follows recess has been found to reduce food waste, as does giving kids more time to eat. Lunch that is scheduled too soon after breakfast can result in more plate waste, as can scheduling lunch too late, giving kids time to snack on other foods.

Another way to reduce waste is to serve better food. But the Tribune reported that one of the reasons children in Chicago rejected the cafeteria food was because it wasn’t seasoned. The USDA’s proposed guidelines would reduce salt in school food by half over 10 years to reflect the advice given in the Dietary Guidelines for Americans. Americans get most of their salt from processed foods, which means the food industry will have to find ways to make processed food with much less sodium, or schools will have to start cooking a lot more meals from scratch. Most are not equipped to do so at the moment.

Schools may also be able to increase student acceptance of foods by involving them in menu selection and by incorporating nutrition education programs that include taste-testing foods in the cafeteria before they are served. As I’ve noted many times, the menu here in D.C. has improved significantly in the last year, but there’s nobody in the cafeteria talking to the kids about it. Consequently, I’ve seen all sorts of great food–sauteed local zucchini, for instance, or roasted local sweet potatoes–going straight into the trash without the kids so much as trying it.

The USDA also is funding research into how behavioral science might be deployed to get kids to actually eat healthier foods rather than throwing them away.

The proposed USDA meal guidelines call for doubling fruit and vegetable portions and vastly increasing “whole grain-rich” products in the food line. These changes are likely to increase the cost of serving school food dramatically. But unless steps are taken to engage kids and their parents in this process, my guess is that a great deal of that food will end up at the landfill.

    Thanks for taking a balanced approach to this issue and the article in question. I work with 1000s of Chicago school kids with our program Delicious, Nutritious Adventures. I have spoken with a ton of kids about the new menus unveiled this year by Chartwells. Their biggest complaint is that the nachos are gone. Kids who are used to eating lots of high sodium, HFCS laden processed foods are going to have a transition with more nutritious options. To use an example, while we healthy eating advocates may love kale chips, they don’t taste just like a Lay’s potato chip and we need to educate kids as to why its important to incorporate healthier options not just tell them that it’s just as good as what they’re used to.

    We also need to make that education fun and delicious – something that we strive to do with the 20 plus Chicago public schools with which we work.

    Oh, and by the way, as someone with a pretty good palate, the options that I’ve tried from Chartwells’ new menu are surprisingly good. Are they nachos loaded with fake cheese? No. But, for school food prepared off site, it’s better than I would have expected.

    I use to work in a school cafeteria and saw so much waisted everyday. the worst part was seeing the food that was not even opened like milk, yogurts, cheese sticks and more just being thrown away. we use to keep them on a table in the middle of the cafeteria so that if some one did not have enough for lunch or was still hungry could go and help themselves. now the school has put a stop to that and everything gets thrown away what a waist. they won’t even consider donating it to the local food shelter. what can I do? Are there any organisations out there that can help?
    thanks for listening.

    Eliminate school lunch altogether. Force the responsibility on the parents instead of taxpayers and stop not only the direct waste but also the ancillary waste of fuel to deliver food, etc. And it will discourage illegal immigration as the free babysitter and meal ticket will be less desirable.

    Thanks for all that intel, Milla. From the one year of Russian I took in college, I can see how “borsch” might become “borscht” from the cryllic original. My information on this soup came from the several different recipes and histories given in “Please to the Table,” a book that won a James Beard award and was considered a definitive text on Russian and Slavic cuisine. And you’re right: The spelling in that book was b-o-r-s-c-h-t. Apparently, that’s how at least half the world spells it. So if you are determined to police this, I’d say you have your work cut out for you.

    Does this mean no Christmas pudding for Tiny Tim, Brad?

    Who wrote this article? I’m writing a speech for my debate team about this.

  • Ed Bruske

    What do you mean, Violet, by “who wrote this article?” If it appears on this blog, it was written by me, unless otherwise indicated.

    Good luck with your debate.

    In Arizona, elementary students can get a “free” breakfast and a reduced fee lunch. This is good for students that need it. And, schools do a better job than parents could do at providing nutritious food–schools even worry about it!

    The thing that has always bothered me is why a student who starts at 8:00 and has lunch at 11:30, needst to have junk food at 9:45?

    Of course it is the caring parents who send the crap–I don’t know of any 2nd/3rd graders who go grocery shopping.
