Yes, celery does contain oxalates, and it actually has a moderate amount compared to some other vegetables.
If you’ve been wondering whether celery contains oxalates because you’re watching your kidney health or managing a condition like gout, you’re asking the right question.
Celery contains oxalates at levels that are generally considered safe for most people, but it’s still worth knowing the numbers if oxalates are a concern for you.
In this post, we’ll look at how many oxalates celery contains, why that matters, and who should pay closer attention to this crunchy green stalk.
Let’s get into it.
Does Celery Contain Oxalates?
Celery contains oxalates, and here’s what you need to know about them.
Oxalates are natural compounds found in many plants, and celery is one of them.
The amount in celery is moderate, not extremely high, but not negligible either.
That’s why it’s smart to understand where celery falls on the oxalate spectrum before you load up your plate.
1. The Oxalate Content in Celery
A typical serving of celery contains roughly 10 to 15 milligrams of oxalates per cup.
That’s a moderate level, which means celery contains oxalates but not in the alarming amounts you’d find in spinach or rhubarb.
For context, spinach can pack over 600 milligrams per cup, so celery is far lower on the scale.
This is why most people don’t need to worry about the oxalates in celery.
2. Why Celery Contains Oxalates at All
Celery contains oxalates because plants produce them naturally as part of their growth and defense systems.
Oxalates help plants manage calcium levels and protect against certain stressors.
So when you eat celery, you’re consuming these naturally occurring compounds along with all the fiber, water, and vitamins.
It’s simply part of how the plant works, and it’s completely normal.
3. Celery Contains Oxalates but Also Hydration
One reason celery contains oxalates without causing much trouble is its incredibly high water content.
Celery is about 95% water, which helps dilute the oxalates as your body processes them.
Staying hydrated also helps your kidneys flush out oxalates more efficiently.
So celery’s natural hydration works in your favor here.
Who Should Watch the Oxalates in Celery?
Most people can enjoy celery without thinking twice about oxalates.
But some folks may need to keep an eye on how much celery they eat.
Here’s who should pay a bit more attention.
1. People with Kidney Stone History
If you’ve had calcium oxalate kidney stones, your doctor may suggest limiting high-oxalate foods.
Since celery contains oxalates, it’s worth discussing with your healthcare provider.
That said, the moderate amount in celery means it’s often still fine in normal portions.
The bigger culprits are usually spinach, beets, and nuts.
2. Those with Kidney Disease
People with chronic kidney disease may need to monitor oxalate intake more closely.
Because celery contains oxalates, it might be part of a broader conversation about your diet.
Your renal dietitian can help you figure out how much celery fits into your plan.
Everyone’s situation is different, so personalized advice matters.
3. Individuals with Gut Absorption Issues
Some conditions, like Crohn’s disease or malabsorption disorders, can increase oxalate absorption.
If that applies to you, knowing that celery contains oxalates can help you make informed choices.
Again, celery’s levels are moderate, so it’s rarely the main concern.
But awareness is always a good thing.
How to Reduce Oxalates in Celery
If you love celery but want to lower its oxalate content, there are a few simple tricks.
These methods won’t remove all the oxalates, but they can help.
1. Cooking Can Lower Oxalates
Cooking celery in water can leach out some of the oxalates.
Boiling is especially effective because the oxalates dissolve into the water.
Just drain the water afterward and you’ve reduced the amount you consume.
So yes, celery contains oxalates, but cooking can bring those numbers down.
2. Pair Celery with Calcium
Eating calcium-rich foods alongside celery can help.
Calcium binds to oxalates in your gut, which keeps them from being absorbed into your bloodstream.
So a little cheese with your celery sticks, or yogurt in your smoothie, can make a difference.
This is a smart strategy if you’re sensitive to oxalates.
3. Stay Hydrated
Drinking plenty of water throughout the day helps your kidneys process oxalates.
Since celery contains oxalates, staying hydrated is a simple way to support your body.
Aim for enough fluids so your urine stays light in color.
Your kidneys will thank you.
So, Does Celery Contain Oxalates?
Yes, celery contains oxalates at a moderate level of about 10 to 15 milligrams per cup.
For most people, that’s not a problem, and celery remains a healthy, hydrating snack.
But if you have kidney stone history, kidney disease, or absorption issues, it’s worth keeping an eye on.
Cooking celery, pairing it with calcium, and staying hydrated can all help reduce the impact of the oxalates in celery.
So go ahead and enjoy your celery, just be mindful if oxalates are something you need to watch.
