Are Walnuts High In Purines

Walnuts are moderately high in purines, so if you’re watching your intake, it helps to know where they fall on the scale.
 
The good news is that walnuts are high in purines compared to some nuts, but they’re still in the moderate range overall, not the very high range that organ meats and certain seafood occupy.
 
If you’ve been asking “are walnuts high in purines?” because of gout or kidney stone concerns, the short answer is that they sit somewhere in the middle, and portion size matters a lot.
 
In this post, we’ll break down whether walnuts are high in purines, how they compare to other foods, and how to enjoy them without stressing your joints or kidneys.
 

Are Walnuts High in Purines? Here’s the Real Answer

Walnuts are high in purines when compared to many other nuts, but they’re still considered a moderate-purine food rather than a high-purine one.
 
That distinction matters because most gout guidelines focus on limiting foods in the very high category, not the moderate one.
 
Let’s look at why walnuts land where they do in the purine conversation.

1. Walnuts Contain Moderate Purine Levels

Walnuts typically contain around 25 to 40 milligrams of purines per 100 grams, which places them in the moderate tier.
 
For context, foods are usually grouped as low (under 50 mg), moderate (50 to 150 mg), or high (over 150 mg per 100 grams).
 
So if you’re asking whether walnuts are high in purines, the honest answer is that they’re on the lower end of moderate, closer to low than to dangerous.
 

2. They’re Much Lower Than Meat and Seafood

When people worry that walnuts are high in purines, they often don’t realize how much higher animal foods can be.
 
Organ meats like liver and kidney can exceed 300 milligrams per 100 grams, and sardines and anchovies are similarly loaded.
 
Walnuts don’t come close to those numbers, which is why most nutritionists don’t flag them as a food to avoid.
 

3. Nuts Generally Rank Lower on the Purine Scale

Most nuts, including walnuts, almonds, and pecans, fall into the low-to-moderate purine range.
 
That means if you’re comparing walnuts to other purine sources, they’re far from the worst offender on your plate.
 
So while walnuts are high in purines relative to, say, a handful of macadamias, they’re not high in the way that matters most for gout sufferers.
 

Why Purines Matter If You Have Gout

Purines are natural compounds found in many foods, and your body breaks them down into uric acid.
 
When uric acid builds up faster than your kidneys can flush it out, crystals can form in your joints, which is what triggers a gout flare.
 
That’s why anyone dealing with gout tends to ask whether walnuts are high in purines before adding them to their snack rotation.

1. Plant Purines Behave Differently

Here’s something reassuring: research suggests that purines from plant sources like walnuts don’t raise gout risk the way purines from meat and seafood do.
 
Studies have found that people who eat more plant-based purines don’t experience more gout attacks.
 
So even though walnuts are high in purines compared to some foods, their plant-based origin makes them a gentler choice.
 

2. Walnuts Bring Anti-Inflammatory Benefits

Walnuts are packed with omega-3 fatty acids, which help reduce inflammation throughout the body.
 
That’s actually a plus for anyone managing gout, since inflammation is the root of the pain during a flare.
 
So while you might wonder if walnuts are high in purines, their anti-inflammatory perks can outweigh the purine concern for most people.
 

3. Portion Size Keeps Purines in Check

A standard serving of walnuts is about one ounce, or roughly 14 halves, and that portion delivers only a small amount of purines.
 
The trouble only arises when you eat them by the handful straight from the bag, day after day.
 
So yes, walnuts are high in purines if you overdo it, but a sensible serving keeps things well within safe limits.
 

How to Enjoy Walnuts Without Worrying About Purines

If you love walnuts but want to keep purines in check, a few simple habits go a long way.
 
You don’t have to give up walnuts just because they contain purines, and here’s how to enjoy them smartly.

1. Stick to a Small Daily Serving

Keep your intake to about one ounce per day, which is the amount most studies associate with health benefits.
 
That serving keeps the purine load low while still giving you the omega-3s and antioxidants walnuts are known for.
 
So if walnuts are high in purines in your mind, a measured portion puts that worry to rest.
 

2. Pair Them With Low-Purine Foods

Balance your walnuts with low-purine choices like fruits, vegetables, and whole grains.
 
This keeps your overall purine intake for the day in a comfortable range.
 
It also means you’re not relying on walnuts alone for your protein or fat needs, which helps with variety too.
 

3. Drink Plenty of Water

Staying hydrated helps your kidneys flush out uric acid more efficiently.
 
If you’re eating walnuts and wondering whether they’re high in purines, water is your best friend for keeping uric acid levels steady.
 
Aim for eight to ten glasses a day, especially if you’re prone to gout or kidney stones.
 

So, Are Walnuts High in Purines?

Walnuts are moderately high in purines, but they’re nowhere near the levels found in organ meats, sardines, or anchovies.
 
For most people, including those managing gout, walnuts in reasonable portions are perfectly fine and even beneficial thanks to their anti-inflammatory omega-3s.
 
The key takeaway is that walnuts are high in purines only when you compare them to other nuts, not when you compare them to the foods that actually trigger gout attacks.
 
So go ahead and enjoy a small handful, keep your water intake up, and rest easy knowing your snack isn’t the enemy.
