Your kid wants to go vegan. Should you let them?

Hi readers! Shayla Love here, science journalist and longtime fan of Your Mileage May Vary. I’m honored to be subbing for Sigal Samuel while she’s out on parental leave. I’m diving into your questions as a way to help understand human nature and our choices through multiple lenses: philosophical, psychological, and beyond. Please send in any emotional, body/brain, sociological, perceptual, or other kind of life quandaries you might have.

My child, age 9, has decided she’s vegan. Neither of her parents are even vegetarian — we’re “free range chicken/grass fed beef” types. She has learned about veganism from friends at school, and seems to have come to her position more or less on her own. I want to encourage her ethical choices, but her mother and I agree that children should be introduced to new foods and flavors at this age. She has no allergies or intolerances that we know of. I worry that making accommodations for her dietary restriction may lead to a lifetime of picky eating, even if hers is a reasonable and ethical approach. She seems to be uncomfortable when her mother or I cook meat for meals we share, even if we make her another option. What should I do to support my daughter?

Dear Hold the Beef, 

When I was around your daughter’s age, I went to Hawaii with my parents. One night, we ate dinner on the beach, and we watched as a pig was dug up from an underground steam oven. I was horrified to see its face and nose; most of the meat I had eaten so far in my life didn’t resemble the animal it came from. A few years later, I became a vegetarian, and then in my 20s, a vegan.

I share this story to reveal my slight bias in answering your question, but also my understanding of the ethical awakening your daughter might be experiencing. As you figure out how to talk to your child about what she decides to eat, we can at least table discussing the pros and cons of veganism itself. Instead, you should think about what amount of autonomy your child should have, and whether the moral decision-making she wants to engage in matches with her current stage of development. 

People don’t turn 18 and then suddenly start engaging morally with the world. As we grow up, we try to understand right and wrong in fits and spurts. Lawrence Kohlberg, a 20th-century American psychologist, is best known for attempting to track a person’s moral development throughout their life. 

Kohlberg presented people with hypothetical dilemmas in order to come up with six moral stages. In one example, he asked people of different ages about a dying woman who could be cured by a drug that was cheap to make, but that a manufacturer was charging an exorbitant fee for. The woman’s husband ends up stealing the drug. Is that right or wrong?

Kohlberg observed that in answering questions like this, young children have what he called a “preconventional morality”: Their notions of right and wrong are dictated by what their parents think, and the avoidance of punishment when breaking those rules. For instance, the main reason not to throw your dinner on the ground or hit your brother was to avoid consequences from parents, not a feeling that there’s something wrong about that action. 

Kohlberg thought this stage lasted until around age 9, and in the next period, children began to understand that there isn’t just one correct action, but that people could have different moral ideas based on their social context. To sum up the rest of the stages quickly, each one progresses to encompass more views — like the moral agreements necessary to make a society function — and more complexity — like the realization that a seemingly immoral action can ultimately be moral, like stealing medicine for one’s wife. 

It’s useful to pinpoint where your daughter finds herself on Kohlberg’s timeline. It sounds like she’s in the shift from the first stage and into the later ones. What you’ve decided — that it’s okay to eat meat if it’s free-range or grass-fed — is no longer sufficient for your daughter in terms of guiding her own actions. That can be a jarring moment for a parent, but at least, according to Kohlberg, it’s a sign of maturation. Your child should, at this age, start to consider her friends, as well as the experiences she’s had without you, when making an ethical choice. 

But I’m her parent, you may protest. That doesn’t necessarily mean that your job is to exclusively provide black-and-white directives. 

Alison Gopnik, a psychologist and philosopher at the University of California Berkeley, has written about the unique perspective and personhood of children (including babies). In her book The Gardener and the Carpenter, she questions how people have come to define the act of parenting as having specific goals in mind for their children. This approach is like being a carpenter, she writes, who follows instructions to assemble a predetermined piece of furniture. She argues that parenting is more like gardening: You cultivate the soil and the environment and realize that you could produce any number of different flowers, fruits, or vegetables. Growth is the point, not a by-the-book final product. 

I see Gopnik in alignment with Jean-Jacques Rousseau, the 18th-century philosopher whose novel Émile, or On Education surprised its readers by advocating for a freer and child-centered approach to teaching. Émile, a young wealthy boy, is tutored — in high contrast to the expectations of the day — without strict rules. Rousseau thought you couldn’t make a child turn into an adult any faster, and it was foolish to try. He also thought that children had to learn by having their own experiences out in the world, and learning from those, rather than just overly didactic lessons. 

As your daughter dips her toe into the morality of eating meat, Rousseau would also remind you not to expect her to have the most mature ideas about veganism or her meal plan. She is still young, and may just have come across an idea that feels ethically important to her. Your role as her parent is to help her develop her nuanced morality, a process Kohlberg suggests will continue, and not steer her towards one way of eating over another. Be Gopnik’s dietary gardener, not carpenter. 

Of course, parents do have rights over their children, and an obligation to keep them safe. When we’re young, we’re not always equipped to make the right choice (some would argue this continues into adulthood, too). If your daughter decided to take up smoking cigarettes, for instance, you would step in because her choice would negatively affect her health. As her parent, you should still guide her to build healthy habits. 

You say you’re worried about your daughter becoming too picky, or not being exposed to enough foods if she becomes a vegan. But rather than push back on the choice itself, you can explain what else her choice entails. You can do so in an age-appropriate way. Talk about the nutrients that she might be missing out on if she stops eating meat, dairy, and eggs, and find books or videos about what foods might be a good substitute. 

For me, becoming vegan actually exposed me to all kinds of foods that I might not have eaten otherwise: from Asian and Indian cuisines that are very veggie-friendly to many other protein- and iron-rich plant-based foods. You could collaborate with your daughter to cook vegan meals for the whole family; no challenge sparks a budding home cook more than making delectable tofu. 

I should add that I’m no longer a vegan. I learned a lot from committing to a diet that wasn’t always convenient or tasty, in support of my values. Then, after more than a decade, I incorporated eggs and fish back into my diet. It’s likely that your daughter will continue to change the choices she makes as she tries to align her actions with her maturing moral views about the world. 

Whether or not she eats grass-fed beef with you in her teens, you should be glad that she seems to care about what impact she’s having in the world. It means you’re raising a person whose ethics are developing strongly, even as what’s on your dinner plate may change while she figures it all out.  

Bonus: What I’m reading

  • Speaking of tofu, I revisited an essay that George Stiffman (a self-proclaimed “tofu guy”) wrote for Asterisk Magazine about how soybean curds are prepared in China. Warning: This article will make you hungry! He dives into all the creative culinary preparations of tofu that are tragically absent in the West. 
  • Several years ago, I bought a plant-based cooking book especially for children, The Vegan Cookbook for Kids: Easy Plant-Based Recipes for Young Chefs. It was a present for a non-vegan family, but the kid in question was interested in learning how to cook, and when kids cook vegan, parents don’t have to worry about them handling raw meat! Looking over these snacks and meals again, I see several tasty things that I wouldn’t mind making for myself, even as a non-vegan, and non-child. 
  • When I was a vegan in New York City in the 2010s, I wasn’t constrained to sad tofu and sprout sandwiches. It seemed like every week a brand-new vegan restaurant opened up, covering every cuisine, and with star chefs at the helm. But lately, all my favorite vegan restaurants have been closing. Turns out I’m not imagining it, as Vox’s Marina Bolotnikova wrote in her article: “Where did all the vegan restaurants go?” She investigates why these establishments have become rarer, and what we’ll miss out on if they completely disappear.
