.. Canadian pediatrician Clara Davis, who conducted a series of
experiments in the 1920s and ’30s to see what would happen if small children, including babies, were allowed to pick their own foods. For her study, Davis was able to round up 15 infants from indigent teenage moms or widows and supervise all of their eating for periods ranging from six months to 4½ years, according to articles she published in
1928 and
1939 in the Canadian Medical Association Journal and a
2006 re-examination of her work in the same publication.The
children were allowed to choose among 34 items, including milk, fruit, vegetables, whole grains and beef, both raw and cooked.
They made some rather eccentric choices, including fistfuls of salt, and most were apparently fond of brains and bone marrow. Sometimes they ate little, and sometimes more than an adult (notably, six hard-boiled eggs on top of a full meal, or five bananas in a single sitting). The tiny subjects varied widely in their self-chosen menus, but the idiosyncrasies evened out over time, and each child, Davis reported, ended up eating a balanced and complete diet.
Sickly and scrawny at the start of the study, they became healthy and well-nourished, she wrote, supporting a concept that was becoming known at the time as body wisdom. “For every diet differed from every other diet, fifteen different patterns of taste being presented, and not one diet was the predominantly cereal and milk diet with smaller supplements of fruit, eggs and meat that is commonly thought proper for this age,” she wrote. “They achieved the goal, but by widely various means, as Heaven may presumably be reached by different roads.”
For decades, experts relied on the study to support the claim that when left to their own devices, children naturally eat what’s best for them. What it actually proved, however, is that children naturally eat a healthy diet when they’re provided only with wholesome options. Davis’s study excluded processed foods, refined flours and sugar. She planned a follow-up experiment to see what would happen if children could choose from processed foods as well, but she never carried out the research.
Not in a clinical setting, anyway. In an uncontrolled and undocumented way, the study has been proceeding on a mass scale for the past 80 years. It shows that given enough choices, children are no more likely to eat what their bodies need than I am—which is not at all, unless my body actually does require Diet Mountain Dew and tortilla chips.
Benjamin Spock discussed Davis’s study at length in his 1946 classic “Baby and Child Care,” using her findings to encourage parents to take a more relaxed approach to feeding. By getting worked up about it, he wrote, you could turn a temporary issue into a lifelong problem.
This is indeed what happened over the next half-century, as children grew fussier and fussier, though whether this was because parents ignored Dr. Spock’s advice or followed it is unclear and probably beside the point. Kids started demanding specific foods because there was now an enticing range of foods marketed specifically to them.
Few products did this better than breakfast cereal. Previously targeted at health nuts, after World War II cereal was aggressively marketed to children using cartoon characters as well as sugar, the magic fairy dust of the age. As Gary Taubes documents in “The Case Against Sugar,” the mid-20th century saw the introduction of sweetened cereals including Sugar Smacks, Sugar Smiles, Sugar Rice Krinkles, Sugar Jets and Sugar Stars. Sugary sodas were presented as nourishment for the whole family. A Seven-Up ad of the mid-1950s featured an infant drinking from a soda bottle: “So wholesome you can give it to babies and feel good about it.”
Midcentury was also a golden age for “junk food.” The phrase first came into use among dietitians of the 1950s who worried about the explosion in processed foods and refined sugars. It entered the Merriam-Webster Dictionary in 1960 to signify anything “appealing and enjoyable but of little or no real value;” the Oxford English Dictionary noted that it was aimed at juvenile tastes.
Many of the big fast-food chains emerged at the same time, promoting items high in fat and salt, like burgers and tacos, which could be served at lightning speed and consumed that way, too. Innovations like ranch dressing (made with buttermilk and mayonnaise) and Tater Tots joined the mid-’50s smorgasbord. No wonder kids didn’t want to eat their peas.
By the 1960s and ’70s, fussy eating was widespread enough to make Dr. Seuss’s “Green Eggs and Ham” a best seller and Life cereal’s “Little Mikey” commercial (“He won’t eat it! He hates everything!”) a cultural phenomenon.
But pickiness didn’t mean that kids were eating less. The trend coincided with overeating. A 2010 study by nutritionists Barry M. Popkin and Kiyah J. Duffey published in the American Journal of Clinical Nutrition found that the average intake of American kids rose by 190 calories a day between 1977 and 2006. The number of calories consumed at meal times had actually declined over that period. The culprit was snacking, from which the average calorie intake had more than doubled.
Victorians did not snack. Modern kids, by contrast, often have access to Chips Ahoy and Fritos all afternoon, which leaves them with little appetite for dinner. Pickiness becomes a kind of default mode at mealtime, especially when foods without the primal taste sensations of those processed snacks are on the menu. There are good evolutionary reasons for our bodies to crave what is sweet, salty and fatty, but kids aren’t likely on their own to see the need to restrict those delights in the name of a balanced diet.
Consider my son, Sam, whose pickiness is so extreme that, two years ago, his pediatrician referred us to an occupational therapist to address it. We learned that there is little consensus among experts regarding treatment: Some recommend carrot, while others insist on stick. We tried all the methods, but none of them got Sam to eat carrots or anything else.
Sam’s diet at age 7 now consists mainly of things that I know I should be limiting. His staple food is pizza, the one food that works for many children who will only eat one food. The first time Sam ate pizza, it was a where-have-you-been-all-my-life experience, even though its main ingredients—bread, cheese and tomatoes—he will eat in no other form. He will also eat just about any kind of candy, the more revolting, the better, from gummy pimples to chocolate poop to candy snot. But rice makes him gag.
Sam has a peculiar set of food sensitivities, but he also may just be giving us the business. Modern children learn very early that food is one area where they can wield some agency. Long before they can control what comes out of their bodies, they’re controlling what goes into them.
If this is Sam’s power play, it’s something I probably deserve, having used food as a cudgel for most of my own adolescence. I put my own parents through a good 10 years of mealtime torture. Though I ate without complaint the broccoli and squash that my mother served, being confronted with meat of any kind sent me into fight-or-flight mode (and still does). My carnivorous husband behaves the same way when presented with salad. Because we’re adults, we ascribe this not to pickiness but to preference. Meanwhile, our 9-year-old daughter, having watched us both, will eat neither meat nor most vegetables.
What ends up working in “Green Eggs and Ham” is leaving the protagonist alone. I can see the appeal of this approach. Ignorance seems to have worked for centuries; intervention, in the last hundred years or so, rather poorly. I sometimes wonder if it’s time to stop. This suits Sam just fine. He’s happy to make a meal out of four cotton-candy-flavored yogurts and a Popsicle, as he did recently.
On the other hand, I’d like him to reach his full adult height and retain his teeth, which means he’ll have to expand his menu. As Clara Davis demonstrated, children make good choices when all their options are good, but in modern America—and in our own home—that condition rarely holds. Sam is unlikely to start eating kale and quinoa if they aren’t even in the house.
But the new year brings the kind of zeal and optimism that sends a parent to the farmers market, to replace the Bomb Pops with bananas; the pizza, with peas. If we swap the bad choices with better ones, perhaps 2019 will be the year in which Sam learns to keep down exotic foodstuffs like cucumber or toast.
And maybe the rest of us will do better, too: cutting down on the relentless snacking that keeps us from eating more nutritious foods at mealtimes, and trying the healthier foods whose tastes can take longer to appeal. It’s still January, and one can still hope.
