How Important Are Green Vegetables, Really?

Q&A on nutrition

Emily Oster

3 min Read

All my life, my mother has told me that eating at least one green vegetable each day is essential for a healthy diet. My toddler will one day eat a small pile of broccoli and then refuse to touch broccoli for a month. Sometimes a few weeks go by and the green vegetables are barely touched, and I’m not sure in these periods how much to be concerned about this. I’m wondering, though, what do we know about the importance of green vegetables in our diet? Are there actually nutrients that we get from green vegetables that we cannot get from any other food source, or that we get in much greater quantities from green vegetables? And if so, how often does one actually need to eat them to derive this benefit?

—Trying to relax about food

Feeding toddlers is an adventure, and not always a good one. The ages from about 18 months through 6 or so bring (on average) the pickiest eating. Your 15-month-old will eat everything, and then all of a sudden it’s like “white foods or bust.” Even if they are not consistently picky, they can be random. One day your child inhales a giant pile of kale chips. Two days later, they throw them on the floor and cry hysterically. 

The anxiety that can come with this transition and unpredictability is not generally helped by advice that makes it seem like not eating green vegetables will kill you.

Green vegetables contain a number of vitamins — A, C, K, E — and minerals. They also have fiber, which is good for you. Overall, these vegetables are indeed part of a recommended diet. However, it is not the case that they are the only way to get these nutrients. Take something like vitamin C, which is in many green veggies. It’s true that your child needs some vitamin C (if you have literally none, you’ll get scurvy). But vitamin C is in many, many foods. Does your child eat ketchup? Do they ever have juice? Do they eat strawberries? Super, they’re getting enough vitamin C.

The same logic applies to other vitamins. There isn’t anything in green veggies that isn’t in some other foods. So don’t stress out!

If you do want some advice about getting kids to eat more vegetables, the best I can offer is to consider serving them with dip.

Reflux: It’s more common than you think! Comment “Link” for an article by @thepediatricianmom breaking down the information we have about reflux — what it is, what you can do, and red flags to look out for.

This graph shows how reflux changes with age. Nearly half of all babies experience reflux by 3 months, often peaking around 4 months before improving by their first birthday. And remember, if you’re struggling, you’re not alone. The most effective treatment for infant reflux is time. It will get better!

We’re heading into a three-day weekend, which means a lot of you might take the opportunity to do some potty training. 

Here are some things to keep in mind:
🚽 It takes longer than three days (based on the data!)
🚽 Your child will have trouble staying dry at night.
🚽 Poop sometimes comes later than pee – this is common, you just have to work through it.

Trampoline parks: great way to get the sillies out or injury haven? Or both? Comment “Link” for an article breaking down a 2023 study on injury trends in trampoline parks.

Here’s a visualisation based on the paper, showing the injury rate by area. Beware the foam pit and the high-performance areas! Slam-dunking, though, seems fine.

Screens have become a ubiquitous part of classroom life. Is this a good thing? Today on the ParentData podcast, I talk with @jessgrosewrites from the @nytimes. She recently ran a survey asking about kids’ screen usage after not being able to find studies and data on the subject.

“Nothing is all bad or all good. But I think overall, there just has been very little scrutiny into something that has been a massive shift in the way kids learn in the past, let’s say, two decades.”

How do we get our kids excited about math? Can every kid be a “math kid”? Shalinee Sharma of @zearnmath shares her insights on the ParentData podcast. 

When I offered her a magic wand to fix math education, she told me: “We have to pair understanding with memorizing. And the best way to understand really anything, but especially math, is simple pictures, concrete context, just make it feel real, not abstract and theoretical. What’s a negative number? Think about if sea level is zero and then you dive into the ocean, that’s a negative number. And then you climb a mountain, well that’s a positive number… We just need pictures to be a part of mathematics.”

Milestones. We celebrate them in pregnancy, in parenting, and they’re a fun thing to celebrate at work too. Just a couple years ago I couldn’t have foreseen what this community would grow into. Today, there are over 400,000 of you here—asking questions, making others feel seen wherever they may be in their journey, and sharing information that supports data > panic. 

It has been a busy summer for the team at ParentData. I’d love to take a moment here to celebrate the 400k milestone. As I’ve said before, it’s more important than ever to put good data in the hands of parents. 

Share this post with a friend who could use a little more data, and a little less parenting overwhelm.

I spend a lot of time talking people down after they read the latest panic headline. In most cases, these articles create an unnecessary amount of stress around pregnancy and parenting. This is my pro tip for understanding whether the risk presented is something you should really be worrying about.
