Walnuts do contain phytic acid, and yes, they’re considered a food with a moderate amount of it.
If you’ve been wondering are walnuts high in phytic acid, the short answer is that they have more than some nuts but less than others like almonds.
Phytic acid is a natural compound found in many plant foods, and walnuts are no exception.
The amount of phytic acid in walnuts usually ranges between 0.2% and 2% of their dry weight.
That puts them somewhere in the middle compared to other nuts and seeds.
In this post, we’ll take a closer look at whether walnuts are high in phytic acid, how they compare to other foods, and what that means for your diet.
Let’s get into it.
Are Walnuts High in Phytic Acid?
Walnuts are high in phytic acid compared to some foods, but not as high as certain grains and legumes.
Here’s what you need to know about the phytic acid content in walnuts.
1. Walnuts Have a Moderate Phytic Acid Level
Walnuts contain phytic acid, but the levels are generally described as moderate.
When researchers measure phytic acid in nuts, walnuts typically fall somewhere in the middle of the pack.
They have more phytic acid than macadamia nuts or Brazil nuts but less than almonds and peanuts.
So if you’re asking are walnuts high in phytic acid, the honest answer is that they’re moderate, not extremely high.
2. The Amount Varies Based on Growing Conditions
The phytic acid in walnuts isn’t always the same.
Soil quality, climate, and how the walnuts are grown can all affect the final phytic acid content.
Walnuts grown in mineral-rich soil tend to have slightly different phytic acid levels than those grown elsewhere.
This is why you’ll see different numbers in different studies about how much phytic acid walnuts contain.
3. Phytic Acid Is Concentrated in the Skin
Most of the phytic acid in walnuts is found in the thin papery skin that covers the nut.
If you remove the skin, you’re also removing a good chunk of the phytic acid.
But here’s the thing, that skin also contains most of the antioxidants and polyphenols in walnuts.
So stripping the skin to reduce phytic acid means you’re losing some of the health benefits too.
How Walnuts Compare to Other Nuts and Seeds
To really understand are walnuts high in phytic acid, it helps to see how they stack up against other nuts and seeds.
Here’s a quick comparison.
1. Almonds Have More Phytic Acid Than Walnuts
Almonds are known for having one of the highest phytic acid levels among nuts.
Walnuts have noticeably less phytic acid than almonds.
So if you’re trying to lower your phytic acid intake, walnuts are actually a better choice than almonds.
2. Cashews and Peanuts Are Also Higher
Cashews and peanuts both contain more phytic acid than walnuts.
Peanuts especially tend to be on the higher end because they’re technically legumes, not true nuts.
Walnuts sit comfortably below both of these in terms of phytic acid content.
3. Walnuts Have More Than Macadamia Nuts
On the flip side, walnuts do have more phytic acid than macadamia nuts and pine nuts.
Those two are among the lowest phytic acid nuts you can eat.
So walnuts aren’t the lowest, but they’re definitely not the highest either.
4. Seeds Like Sesame and Pumpkin Are Higher
Many seeds like sesame, pumpkin, and sunflower seeds contain more phytic acid than walnuts.
So when you’re asking are walnuts high in phytic acid, keep in mind they’re lower than most seeds.
Does the Phytic Acid in Walnuts Matter?
For most people, the phytic acid in walnuts isn’t a big deal.
Here’s why.
1. You’d Need to Eat a Lot of Walnuts
The phytic acid in walnuts only becomes a concern if you’re eating very large amounts every single day.
A typical serving of walnuts is about an ounce, which contains a small amount of phytic acid.
That’s not enough to cause problems for most healthy people.
2. Phytic Acid Has Some Benefits Too
Phytic acid isn’t just an anti-nutrient.
It also acts as an antioxidant and may have protective effects against certain health conditions.
So the phytic acid in walnuts isn’t something to fear in normal amounts.
3. Soaking Can Reduce Phytic Acid in Walnuts
If you’re sensitive to phytic acid, soaking walnuts overnight can help reduce it.
Soaking also makes walnuts easier to digest for some people.
Just soak them in water, rinse, and they’re ready to eat.
4. Pairing With Other Foods Helps
Eating walnuts with foods rich in vitamin C or fermented foods can help counteract phytic acid’s effects on mineral absorption.
So the phytic acid in walnuts becomes less of an issue when you eat a balanced diet.
So, Are Walnuts High in Phytic Acid?
Walnuts are high in phytic acid compared to some nuts but moderate overall, so they’re not a major concern for most people.
They contain more phytic acid than macadamia nuts but less than almonds, peanuts, and most seeds.
For the average person eating a normal serving of walnuts, the phytic acid content isn’t something to worry about.
If you’re sensitive to phytic acid or eating large amounts, soaking walnuts can help reduce it.
Hope this post has helped you understand whether walnuts are high in phytic acid and what that means for your diet.
