Cashews vs. Peanuts: A Head-to-Head Carbohydrate Comparison
The seemingly simple question of whether cashews or peanuts contain more carbohydrates has a clear answer: cashews are the higher-carb choice. While both are considered healthy and nutrient-dense snacks, their macronutrient profiles differ significantly, especially for those watching their carb intake. Peanuts are technically legumes but are nutritionally comparable to tree nuts and are often grouped with them. Understanding these differences can help you make informed decisions for your diet, whether you are following a low-carb, keto, or simply health-conscious eating plan.
Macronutrient Profile: Carbs, Protein, and Fat
When comparing the nutritional content of cashews and peanuts, looking at their primary macronutrients is essential. For a standard 100-gram serving, the contrast is quite notable.
- Carbohydrates: Cashews contain almost double the amount of carbohydrates compared to peanuts. The primary carbs in cashews are starch and sucrose, which contribute to their sweeter taste. Peanuts, on the other hand, have a much lower net carb count, which is the total carbs minus the fiber content.
- Protein: Peanuts take the lead in protein content. At 100g, peanuts offer a higher protein value compared to the same serving of cashews, making them a great choice for muscle repair and satiety.
- Fats: Peanuts also typically have a higher fat content than cashews. However, both are rich in healthy monounsaturated and polyunsaturated fats, which are beneficial for heart health.
Micronutrient Differences: Vitamins and Minerals
Beyond the macronutrients, cashews and peanuts also have unique micronutrient advantages. Choosing one over the other can depend on which vitamins and minerals you want to prioritize.
- Vitamins: Peanuts are generally richer in several vitamins, including vitamin E and various B vitamins such as B1, B2, B3, and B5. Peanuts also contain more folate (vitamin B9). Conversely, cashews contain vitamin C and vitamin K, which are absent in peanuts.
- Minerals: Cashews are the clear winner for minerals. They are significantly richer in iron, magnesium, copper, zinc, phosphorus, and selenium. Peanuts still offer a good amount of certain minerals, but cashews provide a more concentrated source of many essential micronutrients.
- Fiber: Peanuts contain more dietary fiber than cashews, which aids in digestion and can help with feelings of fullness.
How Serving Size Impacts Your Choice
While comparing 100-gram servings is useful, most people consume nuts in smaller portions, like a one-ounce (28g) serving. A typical one-ounce serving provides:
- Cashews: Around 9-10 grams of total carbohydrates, with a small amount of fiber.
- Peanuts: Approximately 4-6 grams of total carbohydrates, with more fiber than cashews.
For a casual snack, the difference might seem minor, but it can quickly add up if you consume multiple servings, particularly for those on a strict low-carb diet. For instance, two ounces of cashews can contain as many carbs as a slice of bread.
Culinary Uses and Dietary Considerations
The carbohydrate differences also affect how each nut is used in recipes and its impact on specific diets.
- Cooking and Baking: Cashews' sweeter, creamier profile makes them ideal for desserts, vegan cheeses, and thickening sauces. Peanuts, with their more savory and robust flavor, are a staple in stir-fries, satay sauces, and of course, classic peanut butter.
- Keto and Low-Carb Diets: Peanuts are often favored on low-carb diets due to their lower net carb count and higher fiber content. They provide excellent protein and fat without a significant carbohydrate load. Cashews can still fit into these diets, but portion control is more important to stay within daily carb limits.
- Weight Management: Both nuts are high in calories due to their fat content. However, their high protein and fat levels can promote satiety, potentially helping to manage overall calorie intake. Studies have even shown that moderate nut consumption is not linked with weight gain.
Which Nut Should You Choose?
Ultimately, the choice between cashews and peanuts depends on your dietary goals and taste preferences.
- Choose Cashews if: You want a sweeter, creamier texture and a higher dose of minerals like magnesium and iron.
- Choose Peanuts if: You are looking for a lower-carb, higher-protein snack with more fiber and specific B vitamins.
- The Best Approach: A balanced diet often includes a variety of foods to maximize nutrient intake. Integrating both cashews and peanuts in moderation can provide a wider range of vitamins, minerals, and healthy fats.
| Feature | Cashews (per 100g) | Peanuts (per 100g) | Winner |

Conclusion
When it comes to the question of what has more carbs, cashews or peanuts, the data is clear: cashews are the higher-carb option. However, this fact does not make them a "bad" choice. Both nuts are packed with valuable nutrients that contribute to a healthy diet. Peanuts provide more protein and fiber, while cashews offer a richer mineral content. For those prioritizing lower carb counts, peanuts are the better choice for a larger serving, but careful portion control allows both to be enjoyed. The best strategy is to consume a mix of both in moderation to reap the benefits of their diverse nutritional profiles.
