It seems like an age-old problem - kids not eating their vegetables - and it is. Little ones, more interested in macaroni and cheese than sautéed spinach, are still leaving the latter largely untouched.
The proof is both anecdotal - what parent hasn't tussled with this? - and borne out in data. Nine out of ten children, after all, still don't eat enough vegetables, according to the US Centers for Disease Control and Prevention (CDC).
The problem has been blamed, at least in part, for the deteriorating diets of youth. It has also been on clear display ever since the US government updated, in 2013, its nutrition standards for the National School Lunch Program.
Children, suddenly confronted with vegetables on every plate (as required as part of the change), have responded not by eating them but by leaving them on their plates - untouched.
It's a poignant example of how kids are really good at making really bad decisions about food. And it has proved pretty frustrating for health and nutrition advocates, who can't seem to find a reasonable way to get children to eat more healthfully.
But it turns out there might be an ingenious solution hiding beneath everyone's nose.
Researchers at Texas A&M University, looking for patterns in food consumption among elementary school children, found an interesting quirk about when and why kids chose to eat their vegetables.
After analyzing plate waste data from nearly 8,500 students, it seems there's at least one variable that tends to affect whether or not kids eat their broccoli, spinach, or green beans more than anything: what else is on the plate.
Kids, in short, are much more likely to eat their vegetable portion when it's paired with a food that isn't so delicious it gets all the attention.
When chicken nuggets and burgers, the most popular items among school children, are on the menu, for instance, vegetable waste tends to rise significantly. When other less beloved foods, like deli sliders or baked potatoes, are served, the opposite seems to happen.
"Pairings of entrées and vegetables are an important consideration when assessing plate waste among elementary school children," the researchers note.
Indeed, the effect can work the other way around. The study found that children tend to eat less of their entree when popular vegetables (mostly starchy fried vegetables, like french fries, which many wouldn't classify as vegetables) are offered.
When the entree is paired with steamed broccoli - the vegetable children eat the least of on average - kids instead eat more of the main dish.
But these observations are likely more useful as a gauge for how appetizing vegetables are in different contexts than as a subscription for what pairings will lead to the least amount of food waste. Kids' favorite meals, after all, aren't particularly healthy. What's more, they, too, lead to considerable waste.
The notion that food pairings can significantly affect the attractiveness of certain foods isn't new. Traci Mann, who teaches psychology at the University of Minnesota and has been studying eating habits, self-control and dieting for more than 20 years, believes that it can, in fact, be crucial.
One of the simplest ways to eat better is to make it easier to eat better. That involves a strategy Mann calls "get alone with a vegetable," which is similar in that it shows how important context can be. She described the strategy earlier this year:
"Normally, vegetables will lose the competition that they're in - the competition with all the other delicious food on your plate. Vegetables might not lose that battle for everyone, but they do for most of us."
She also noted that it's been effective with kids:
"We've actually tested this in a lot of ways. And it works unbelievably well. We tested it with kids in school cafeterias, where it more than quadrupled the amount of vegetables eaten.
"It's just about making it a little harder to make the wrong choices, and a little easier to make the right ones."
Understanding how something as simple as what a vegetable is served with can have a sizable impact on whether a child eats it is a pretty useful thing.
