Foods high in calcium can be a hot topic of discussion among adults.
What foods have calcium?
How much calcium is in milk?
Which vegetables are high in calcium?
As a pediatric nutritionist, I know parents like you know how important calcium is to kids health. You want healthy kids and you want to make sure your children are getting enough.
Those little bones are growing, after all, and the bone-building nutrients are essential to growth and bone health.
[Read my in-depth guide about calcium called The Calcium Handbook}
In this article, I’ll review what calcium does, why it’s needed for kids, and how you can ensure your child gets enough.
Do Kids Need Calcium?
Some people question the need for calcium in kids. Others have questioned whether milk and dairy products are a necessary component to a child’s diet.
On the flip side, there have been grumbles about whether calcium actually keeps the bones strong, suggestions that plenty of vitamin D can be found in non-dairy foods and from the sunlight. Or, they warn that milk may contribute to childhood obesity.
Let me say this loud and clear: I believe calcium rich foods are required in a child’s diet.Calcium rich foods are required in a child's diet. #bonegrowth #healthykids #kidshealth #thenourshedchild Click To Tweet
Why Calcium Food Sources Matter
For the record, where you get calcium in food is a matter of personal preference.
Other families may just prefer not to consume real milk, for whatever reason, and get their calcium from a variety of different foods, like vegetables.
I answer the question of whether kids really need calcium foods like milk with “it depends.”
Look at your child’s medical circumstances, your family food practices, your child’s eating habits and food preferences (read: what he will eat), and the other realities of making nutrition happen in your home.
They all play out differently for every family.
While I have always been a supporter of milk as part of a healthy diet, I understand that milk isn’t for everyone.
However, calcium is for every growing child. And that means calcium-containing foods.Calcium IS for every growing child. Where is your child getting his calcium from? Click To Tweet
Calcium Foods are Plentiful
Milk is just one food that helps kids meet their calcium requirement.
Surveys and studies show real milk is an easy way for kids to meet their calcium requirements, while also getting a whole host of other important bone nutrients, such as protein, vitamin D, and potassium.
But milk isn’t the only way to meet your child’s calcium needs.
How Much Calcium Do Kids Need?
According to the Institute of Medicine (IOM), the Dietary Reference Intake (DRI) for calcium in children aged 4-8 years is 1,000 mg per day.
The requirement for kids and teens aged 9-18 years is 1,300 milligrams per day.
Which Foods Have Calcium?
The following chart includes foods high in calcium to help your child or teen meet his daily requirements.
The foods you choose to offer, and how you combine them to match the total daily calcium requirement is your choice.

Vegetables High in Calcium
I want to address calcium rich vegetables as I am asked about this topic comes up a lot.
I hear people talk about broccoli, spinach, and other foods, especially vegetables, being high in calcium.
Vegetables are a source of calcium, no doubt. Take a look at the following calcium-containing vegetables:
A cup of oriental radishes (730 mg)
soybeans (500 mg)
cooked collards (357 mg)
turnip greens (250 mg)
These veggies give the highest amounts of calcium per cup, according to the USDA Nutrient Database.
Did you notice? Broccoli didn’t make my list of high sources, kale barely did, and spinach needs to be cooked to be a notable source.
A Reality Check:
The calcium in 1 cup of raw, chopped broccoli is 43 mg.
The calcium in 1 cup of raw spinach is 53 mg.
The calcium in 1/4 cup of almonds is 115 mg.
As a reminder, your young child’s calcium needs are 1,000 mg/day.
Your teen’s requirements are 1,300 mg/day.
(It takes 23 cups of broccoli to equal 1,000 mg calcium.)
I’ve yet to meet a child who is eating enough broccoli, kale or almonds to meet his calcium needs on a daily basis.
You certainly can combine vegetables and other calcium food sources to match calcium requirements, but this takes forethought and planning.
The bioavailability of calcium, or the absorption of calcium in the body from foods, is another factor to consider. Vegetables contain substances like oxalates and phytates, which may interfere with calcium absorption and reduce the overall amount absorbed.
A Resource on Calcium Rich Foods for Kids
I’ve written a small guidebook that digs into your child’s calcium requirements even further, and provides ways to help you make sure your child is growing healthy, strong bones using a variety of calcium foods.
I take into consideration the eating habits of children, making practical suggestions on how to balance the overall diet to encourage plenty of calcium, while helping you with advice about calcium supplements should you have a child who isn’t meeting his needs.
