Walnuts are not high in carbohydrates.
In fact, they’re one of the lowest-carb nuts you can add to your diet.
A single ounce of walnuts (about 28 grams) contains roughly 4 grams of total carbs and 2 grams of fiber.
That means the net carbs in walnuts sit at around 2 grams per ounce.
For anyone wondering are walnuts high in carbohydrates, the short answer is no.
Compared to other nuts and snacks, walnuts fall on the lower end of the carb spectrum.
In this post, we’ll break down the carb content of walnuts, how they compare to other nuts, and why they can still fit into a low-carb lifestyle.
Let’s get to it.
Why Walnuts Are Not High in Carbohydrates
Walnuts are not high in carbohydrates, and several reasons explain why.
1. Most of Their Calories Come From Fat
The biggest reason walnuts aren’t high in carbohydrates is that fat makes up the majority of their calories.
About 65 percent of a walnut’s weight is fat, mostly healthy polyunsaturated fats.
Protein accounts for roughly 15 percent.
That leaves carbs as a very small slice of the pie.
So if you’re scanning nutrition labels and wondering are walnuts high in carbohydrates, the fat content tells the real story.
2. They’re Packed With Fiber
Half of the carbs in walnuts come from fiber.
Fiber is a type of carbohydrate your body doesn’t fully digest.
It passes through your system without spiking blood sugar the way refined carbs do.
This is why nutritionists focus on net carbs, which is total carbs minus fiber.
At just 2 grams of net carbs per ounce, walnuts are a smart pick for keto and low-carb diets.
3. Walnuts Have a Low Glycemic Index
The glycemic index measures how quickly a food raises blood sugar.
Walnuts rank very low on this scale.
That’s because their carb content is small and buffered by fat, fiber, and protein.
So even though walnuts contain carbohydrates, they won’t cause the sharp glucose spikes that bread, rice, or candy will.
This makes them a safe choice for people managing diabetes or watching their carb intake.
4. There’s No Added Sugar
Raw walnuts contain no added sugar.
The small amount of sugar naturally present is minimal.
You’ll only run into trouble with flavored, honey-roasted, or candied walnuts.
Those versions add sugar and can push the carb count much higher.
Stick with plain walnuts and the carb content stays low.
How Many Carbs Are in Walnuts Compared to Other Nuts?
When you ask are walnuts high in carbohydrates, it helps to compare them to their nutty neighbors.
Here’s how walnuts stack up per one-ounce serving:
1. Walnuts vs. Cashews
Cashews are among the highest-carb nuts.
One ounce packs about 9 grams of carbs and only 1 gram of fiber.
That’s more than double the carbs in walnuts.
If you’re counting carbs, walnuts win this matchup easily.
2. Walnuts vs. Pistachios
Pistachios contain around 8 grams of carbs per ounce.
They’re tasty, but they can’t compete with walnuts on the carb front.
Walnuts deliver roughly half the carbs for the same serving size.
3. Walnuts vs. Almonds
Almonds are a close competitor.
They have about 6 grams of total carbs and 3 grams of fiber per ounce.
That puts them slightly higher than walnuts in total carbs.
Both are low-carb friendly, but walnuts edge ahead.
4. Walnuts vs. Pecans
Pecans come in at around 4 grams of carbs per ounce, similar to walnuts.
So pecans and walnuts are both excellent low-carb nut choices.
5. Walnuts vs. Macadamia Nuts
Macadamia nuts are the lowest-carb nut around, with about 4 grams of total carbs and 2 grams of fiber.
Walnuts are right there alongside them.
So when someone asks are walnuts high in carbohydrates, the comparison proves they’re near the bottom of the list.
How to Enjoy Walnuts on a Low-Carb Diet
Walnuts are not high in carbohydrates, so you can enjoy them in plenty of ways without wrecking your carb budget.
1. Sprinkle Them on Salads
Toss a handful of chopped walnuts over leafy greens.
They add crunch and healthy fats without adding many carbs.
2. Add Them to Yogurt
Plain Greek yogurt with walnuts makes a filling, low-carb breakfast.
Just skip the sweetened yogurt to keep the carbs down.
3. Use Them as a Snack
A small handful of raw walnuts is a perfect grab-and-go snack.
Pair them with cheese for an even more satisfying, low-carb combo.
4. Bake With Walnut Flour
Walnut flour is a great low-carb alternative to wheat flour.
It works well in muffins, pancakes, and cookies for anyone cutting carbs.
5. Watch Your Portions
Even though walnuts aren’t high in carbohydrates, they’re calorie-dense.
One ounce is a serving, and it’s easy to eat three or four without noticing.
Measure them out if you’re watching your weight.
So, Are Walnuts High in Carbohydrates?
Walnuts are not high in carbohydrates.
With only about 4 grams of total carbs and 2 grams of net carbs per ounce, they’re one of the lowest-carb nuts you can eat.
Most of their calories come from healthy fats, and half their carbs are fiber.
Compared to cashews, pistachios, and even almonds, walnuts hold their own as a low-carb superstar.
So if you’ve been wondering are walnuts high in carbohydrates, rest easy.
They’re a nutritious, low-carb addition to salads, yogurt, snacks, and baked goods.
Just stick to plain, raw walnuts and keep an eye on portion size.
Enjoy them guilt-free.
