Walnuts vs. Almonds: A Head-to-Head Carb Comparison
Nuts are a cornerstone of many healthy eating plans, praised for their healthy fats, protein, and satisfying crunch. For those on a low-carb or ketogenic diet, the carbohydrate content of their nut choices is a critical factor. While both walnuts and almonds are nutrient-dense powerhouses, a close look at their macronutrient breakdown reveals a slight but significant difference when it comes to carbohydrates.
The key to this comparison lies in the concept of net carbs. Total carbohydrates in any food item include both digestible carbs (sugars and starches) and dietary fiber. Since the body does not digest fiber, it doesn't raise blood sugar levels. Therefore, net carbs (total carbs minus fiber) is the number that matters most for low-carb dieters.
The Nutritional Breakdown: Walnuts vs. Almonds
To make an informed decision, let's examine the nutrient content of a standard 1-ounce (approx. 28-30g) serving of both raw, shelled walnuts and almonds.
- Carbohydrates: A 1-ounce serving of walnuts contains approximately 3.9 grams of total carbohydrates, while almonds have about 6.1 grams.
- Dietary Fiber: Almonds have more fiber per serving, with about 3.5 grams compared to walnuts' 1.9 grams.
- Net Carbs: After subtracting the fiber, a serving of walnuts provides about 2 grams of net carbs, whereas the same serving of almonds offers about 2.6 grams. This makes walnuts the winner in a strict head-to-head comparison for fewer net carbs.
- Protein: Almonds are a slightly better source of protein, with around 6 grams per ounce compared to walnuts' 4.3 grams.
- Fats: Walnuts are slightly higher in fat, largely polyunsaturated fats, including a significant amount of omega-3 fatty acids (ALA). Almonds contain more monounsaturated fats.
- Calories: Walnuts are slightly more calorie-dense, with around 185 calories per ounce versus almonds' 165.
Comparing Macronutrients per 1-Ounce Serving
| Nutrient | Walnuts (approx. 14 halves) | Almonds (approx. 23 whole kernels) |
|---|---|---|
| Calories | 185 kcal | 164 kcal |
| Total Carbs | 3.9 g | 6.1 g |
| Dietary Fiber | 1.9 g | 3.5 g |
| Net Carbs | ~2 g | ~2.6 g |
| Protein | 4.3 g | 6.0 g |
| Total Fat | 18.5 g | 14.1 g |
Beyond Carbs: Other Health Benefits
While the carb count is a primary concern for some diets, it is important to consider the other benefits that each nut offers. Both walnuts and almonds provide a wealth of essential nutrients that contribute to overall health.
Health benefits of walnuts:
- Rich in Omega-3 Fatty Acids: Walnuts are one of the best plant-based sources of alpha-linolenic acid (ALA), a type of omega-3. This is known to support heart and brain health.
- High Antioxidant Content: The polyphenolic compounds in walnuts offer powerful antioxidant effects, helping to reduce inflammation and oxidative stress.
- Cognitive Function: Studies suggest that regular walnut consumption may improve cognitive performance and reduce the risk of neurodegenerative diseases.
Health benefits of almonds:
- Excellent Source of Vitamin E: Almonds are packed with vitamin E, a potent antioxidant that supports skin health and immune function.
- High in Fiber: The higher fiber content in almonds can aid in digestion, promote satiety, and support weight management.
- Essential Minerals: Almonds are a great source of magnesium, calcium, and potassium, which are important for bone health, blood pressure regulation, and muscle function.
- Blood Sugar Control: Research indicates that almonds may help improve glycemic control, making them a favorable snack for those with diabetes.
Which Nut is Right for Your Diet?
Choosing between walnuts and almonds depends on your specific dietary priorities. If you are following a very strict ketogenic diet with an extremely tight carb budget, the lower net carb count of walnuts might be the deciding factor. For others, the higher protein and fiber content of almonds might be more beneficial for feeling fuller and supporting weight management.
It is also worth considering that a varied diet is often the most beneficial. Incorporating both walnuts and almonds into your eating plan will allow you to reap the unique benefits each offers. For instance, you can enjoy walnuts for their omega-3 content and almonds for their vitamin E and mineral profile. Both are excellent, whole-food options that offer far more than just a carb count.
Ultimately, the choice comes down to personal taste and specific health goals. Both nuts are a smart, healthy addition to any diet when consumed in moderation. As part of a balanced diet, including a mix of different nuts can provide a wider array of nutrients for optimal health.
Conclusion
To answer the question, walnuts have slightly less net carbs per serving than almonds, making them a preferable choice for those adhering to a very strict low-carb or ketogenic diet. However, the difference is minor, and both are considered excellent low-carb snack options. Beyond the carb count, walnuts stand out for their high omega-3 fatty acid content, which supports brain and heart health, while almonds are notable for their higher protein, fiber, and vitamin E levels. For most people, the best strategy is to enjoy both nuts as part of a varied and balanced diet to maximize the nutritional benefits.

Nutritional Considerations for Low-Carb Diets
Can I eat both walnuts and almonds on a keto diet?
Yes, both walnuts and almonds are considered keto-friendly and can be consumed in moderation as part of a ketogenic diet. While walnuts have slightly fewer net carbs, the difference is small enough that both can easily fit into a low-carb plan.
How are net carbs calculated?
Net carbs are calculated by subtracting the grams of dietary fiber from the grams of total carbohydrates. Since fiber is a type of carbohydrate that the body cannot digest, net carbs are the measure used to determine a food's impact on blood sugar.
Do roasted nuts have a different carb count than raw?
The carb count of raw and dry-roasted nuts is very similar. The roasting process removes water but does not significantly alter the macronutrient profile. However, be cautious with nuts that have been oil-roasted or coated, as these may contain added carbs.
Which nut is better for heart health?
Both are excellent for heart health, but for different reasons. Walnuts are particularly beneficial due to their high content of omega-3 fatty acids. Almonds are rich in heart-healthy monounsaturated fats and magnesium.
How much is one serving of nuts?
A standard serving size for most nuts is one ounce, which is about 23 whole almonds or 14 walnut halves. Due to their calorie density, portion control is important.
Are there any other low-carb nuts?
Yes, other nuts are also excellent low-carb options. Some examples include macadamia nuts, pecans, and Brazil nuts, which are all very low in net carbs.
Can walnuts and almonds help with weight loss?
Both nuts can support weight management due to their protein, fiber, and healthy fat content, which can increase satiety. Some studies suggest almonds may have a slight edge due to their higher protein and fiber, promoting a feeling of fullness.
What if I don't follow a low-carb diet?
If you are not on a low-carb diet, the marginal difference in carb content between walnuts and almonds is less of a concern. You can simply choose the nut you prefer or alternate between them to enjoy a broader range of nutrients.
Which nut has more protein?
Almonds have slightly more protein than walnuts. A 1-ounce serving of almonds provides about 6 grams of protein, compared to approximately 4.3 grams in a serving of walnuts.
Which nut is better for brain function?
Walnuts are particularly known for their brain-boosting properties due to their high omega-3 fatty acid content. The ALA in walnuts has been linked to improved cognitive function and reduced risk of cognitive decline.
