Why Are Cashews So High In Carbs

Cashews are higher in carbs than most nuts, which surprises a lot of people.
 
If you’ve been asking why are cashews so high in carbs, the short answer is that cashews aren’t true nuts at all.
 
They’re actually the seeds of a tropical fruit, and their botanical makeup is closer to a grain than to an almond.
 
That difference explains a lot about why cashews are high in carbs compared to other nuts you’re used to.
 
In this post, we’ll break down why cashews are so high in carbs, how many carbs they actually contain, and whether you need to worry about it.
 
Let’s dig in.

Why Cashews Are High in Carbs

Cashews are high in carbs because of what they are and how they store energy, and here’s why:

1. Cashews Are Seeds, Not True Nuts

The biggest reason cashews are high in carbs comes down to botany.
 
Cashews grow on the outside of a cashew apple, and they’re technically seeds, not tree nuts.
 
Seeds are designed by nature to store energy for a future plant, and that energy is largely packed as starch.
 
True nuts like almonds and walnuts store more of their energy as fat instead, which is why they’re so low in carbs.
 
So when people ask why are cashews high in carbs, the honest answer starts with the fact that cashews were never nuts in the first place.
 

2. They’re Starch-Rich by Nature

Cashews contain more starch than most nuts, and starch is a carbohydrate.
 
Where almonds might contain around 9 grams of carbs per ounce, cashews can hit 8 to 9 grams of carbs in a smaller serving, with more of it coming from starch.
 
This starch content is exactly why cashews are high in carbs when you compare them side by side with pecans or macadamias.
 
Their starchy nature also explains why cashews taste slightly sweet and creamy when you bite into them.
 

3. Their Fat Profile Is Different

Cashews do contain fat, but less of it than most other nuts.
 
When a food has less fat, the carbohydrate percentage of that food naturally goes up.
 
That’s part of why cashews are so high in carbs relative to their total calorie count.
 
It’s not that cashews are loaded with sugar, it’s that they simply don’t have the fat density that pushes other nuts into low-carb territory.
 

4. The Cashew Apple Plays a Role Too

Here’s a fun fact that ties into why cashews are high in carbs.
 
Unlike almonds tucked inside hard shells, cashews hang beneath a sweet, juicy fruit.
 
The seed draws energy from that fruit as it develops, and that energy takes the form of stored carbohydrates.
 
This close relationship with a sugar-rich fruit is another reason cashews are high in carbs compared to nuts that grow inside dry shells.
 

How Many Carbs Are in Cashews?

A one-ounce serving of raw cashews (about 18 nuts) contains roughly 8 to 9 grams of carbohydrates.
 
Of that, around 1 gram is fiber and about 1.5 grams is natural sugar.
 
The rest is starch, which is the main driver behind why cashews are high in carbs.
 
Compare that to macadamia nuts at about 4 grams of carbs per ounce or pecans at around 4 grams.
 
So cashews deliver more than double the carbs of some of the lowest-carb nuts out there.
 
It’s still not a huge amount in the grand scheme of things, but if you’re counting carbs carefully, it adds up quickly.
 

Do High-Carb Cashews Fit Your Diet?

Whether cashews fit your diet depends on your goals, and here’s how to think about it:

1. On a Keto or Low-Carb Plan

If you’re strictly keto, cashews are high in carbs enough that you should enjoy them in small portions.
 
A handful can eat up a good chunk of your daily carb allowance compared to other nuts.
 
Many low-carb eaters swap cashews for almonds, pecans, or macadamias when they need a nutty snack.
 
That said, a small sprinkle of cashews on a stir-fry won’t wreck your progress.
 

2: On a Balanced or Moderate-Carb Diet

On a balanced diet, the fact that cashews are high in carbs isn’t a problem at all.
 
They bring healthy fats, protein, magnesium, and copper to the table, along with that satisfying creaminess.
 
Portion control is the real key here, just like with any calorie-dense food.
 

3. Watch Out for Roasted and Flavored Cashews

Here’s where the carb content can sneak up on you.
 
Honey-roasted cashews or those coated in sugar and seasonings can push the carb count much higher than plain raw cashews.
 
If carb intake matters to you, stick with dry-roasted or raw cashews and check the label.
 
Plain cashews are high in carbs on their own, so added sugar only makes the numbers climb.
 

4. Keep Portions Reasonable

Just because cashews are high in carbs doesn’t mean you need to avoid them entirely.
 
A small handful as a snack or a tablespoon tossed into a recipe keeps the carbs modest.
 
Pairing cashews with protein or healthy fats can also help slow digestion and keep you satisfied.
 
That way, you get the creamy crunch without overdoing it.
 

So, Why Are Cashews So High in Carbs?

Cashews are high in carbs because they’re seeds rather than true nuts, and seeds store more of their energy as starch.
 
They also carry less fat than most nuts, which pushes their carbohydrate percentage up.
 
A one-ounce serving lands around 8 to 9 grams of carbs, roughly double what you’d get from pecans or macadamias.
 
None of this means cashews are off-limits, it just means they deserve a bit more awareness on low-carb days.
 
Enjoy them plain, keep an eye on portions, and you can still fit these creamy, delicious seeds into a healthy diet with ease.
