I keep seeing headlines like these bouncing around my Facebook and Twitter feeds:
“Colorful Plates Boost a Picky Eater’s Appetite“
Have you seen them, too? After doing the research for my article on getting picky eaters to try more veggies, I take notice when I see claims of a new strategy that might be useful to parents of picky eaters.
I went to take a look at the study and was further intrigued when I found that it was conducted at Cornell University, my alma mater. Go Big Red! Cornell has a very well-respected Nutrition department*, so I had high hopes for this one. I thought it even might make a good blog post. But when I actually read the study, I decided it wasn’t much help at all. This study told us nothing about how to get picky eaters to eat better or how to improve anyone’s appetite – the headlines were exaggerated. [*For the record, the authors of this study were from departments of Applied Economics and Management at Cornell and Art, Media, and Design at London Metropolitan University – they aren’t nutritionists.]
I can’t tell you how many times I’ve started writing blog posts about new studies and then stopped mid-way through when I realized that I was spending more words talking about the limitations of the study than the findings. So I wasn’t planning to blog about this study until I saw it covered on the Wall Street Journal’s family blog. Their article concluded, “To get our picky kids to eat, we may have to become both short-order cooks and food stylists.” No pressure there.
The UK’s Daily Mail also published an online article about the study. It stated, “Scientists have found youngsters are more likely to clear their plate when there is more colour and choice.”
Scientists have found nothing of the sort. Here’s the run-down of what they actually did find:
The study included 23 children between the ages of 5 and 12-years-old and 46 adults aged 26 and above. The kids were shown different groups of photos of plated food and asked, “Which is the picture that you like the most?” The adults answered the same questions as an online survey.
The photos included plates with different numbers of colors and types of food (ie. a plate with just eggs vs. a plate with eggs, bacon, and toast) and different arrangements of foods. Among the arrangements tested were plates with fun designs, as described in the paper: “Bacon was arranged as a smile along the lower perimeter of a plate, peas were arranged in a heart shape and cupcakes and cakes were decorated with images.” How sweet!
What did we learn from this food photo exercise?
1. Children preferred plates with 6 colors, while adults preferred only 3 colors.
2. Children preferred up to 7 types of food on their plates, while boring adults liked just 3.
3. Children preferred the entrée to be in the front of the plate, while adults preferred it in the middle.
Now let’s talk about some problems with the study and how it has been presented in the media as the next cure-all for picky eating:
• This was a study about which pictures kids and adults find appealing. No actual food was offered or eaten. According to the paper, not even the idea of eating the foods shown in the photos was mentioned to the participants. They were asked, “Which is the picture that you like the most?” not “Which meal would you most like to eat?” For all we know, the kids chose photos based on which ones they’d like to have on their walls or in picture books. And yet, the Daily Mail says, “Scientists have found youngsters are more likely to clear their plate when there is more colour and choice.” Do you see the problem?
• The media has portrayed this study as being about picky children, but the researchers didn’t select for pickiness when they recruited kids to participate. The kids were simply a group of summer campers whose parents gave permission for them to participate. The children in this study were 5 to 12 years old, but the authors mention in their paper that the peak of picky eating occurs between ages 2 and 6, which sounds about right to me. If we are trying to understand picky eaters, we should study picky eaters. This study was not about picky eaters. To their credit, the authors didn’t make any claims that plates with more color and variety would be more likely to be cleared by picky eaters – that is a claim made by the media.
The “reporting” on this study is a perfect example of the problem with the media’s coverage of science. The media chooses studies that they think will be easy to understand and that parents will perceive as being applicable and useful in their lives. And then, in this case, they over-interpret the study to beef up its everyday applicability.
It’s pretty annoying. You might think that it isn’t such a bit deal, but I would argue that it is. First of all, parents read the articles about this study and start to think that it isn’t enough to offer a protein, a grain, a vegetable, and a glass of milk for lunch. Crap, that’s only 3 colors and 4 types of food! Time to make things more complicated – or at least feel guilty about it. Actually, what is more likely is that parents will see these headline and disregard the whole thing, because they know that next week a study will come out telling them to try offering foods one at a time. It won’t matter if the one-at-a-time study was conducted in young toddlers with real food. By that time, parents have already decided that science is just not that helpful to them. This kind of crap is why scientists have a reputation of being out of touch and unable to make up their minds.
I don’t think this study is helpful to parents, and the media write-ups have been plain stupid. You want to know who might benefit from this study? I’d be willing to bet that food marketing types are paying attention. Want to design a Lunchables meal that kids will beg for? Arrange more appealing photos for a McDonald’s Happy Meal menu? Looking for reasons to add more food dye to kids breakfast cereal?
For all my complaining, I do think it is kind of cool that the kids liked seeing a lot of color on their plates. It is a great idea to try a greater variety of fruits and veggies with our kids. And smiling bacon? I can get behind that, too.
What do your kids prefer – more or less variety on their plates?
