Understanding the Nutritional Landscape
Both cashews and peanuts are incredibly popular snack foods, cherished for their satisfying crunch and nutritional benefits. While peanuts are technically legumes and grow underground, cashews are tree nuts (more accurately, a seed) that grow from the cashew apple. Despite their different botanical origins, they are often compared head-to-head. The central question for many health-conscious consumers is, what has more protein, cashews or peanuts? While the raw numbers show a clear winner, a deeper dive into their macronutrient profiles reveals a more complex story.
Protein and Macronutrient Breakdown
As the data indicates, peanuts consistently offer a higher protein content per serving than cashews. For individuals prioritizing protein intake, especially those on plant-based diets, this distinction can be significant. Peanuts provide a substantial protein boost, contributing to muscle repair, satiety, and overall daily intake. Cashews, while still a good source of protein, are not quite as protein-dense. However, one study noted that cashews might have a higher protein digestibility corrected amino acid score (PDCAAS) than peanuts, suggesting the body can absorb cashew protein more efficiently.
When we look beyond protein, the other macronutrients paint a different picture. Peanuts contain more total fat and are slightly higher in calories, though the majority of this fat consists of heart-healthy monounsaturated and polyunsaturated fats. Cashews, on the other hand, contain more total carbohydrates, though peanuts compensate with a higher fiber content. This difference in macronutrient composition is what makes the final choice depend on specific dietary goals.
Head-to-Head Nutritional Comparison (Per 100g)
This table provides a comprehensive overview of the nutritional differences between raw peanuts and cashews, based on data from Foodstruct.
| Nutrient | Peanuts (Raw) | Cashews (Raw) |
|---|---|---|
| Protein | 25.8 g | 18.22 g |
| Calories | 567 kcal | 553 kcal |
| Total Fat | 49.24 g | 43.85 g |
| Carbohydrates | 16.13 g | 30.19 g |
| Fiber | 8.5 g | 3.3 g |
| Magnesium | 168 mg | 292 mg |
| Iron | 4.58 mg | 6.68 mg |
| Zinc | 3.27 mg | 5.78 mg |
| Copper | 1.144 mg | 2.195 mg |
| Folate (B9) | 240 µg | 25 µg |
| Vitamin E | 8.33 mg | 0.9 mg |
Micronutrient Strengths
While peanuts hold the edge in protein, their micronutrient profile is particularly rich in certain vitamins. Cashews, however, are mineral powerhouses, offering higher concentrations of several key nutrients.
Peanut Micronutrient Highlights
- Vitamins: Peanuts are especially rich in B vitamins, including folate (B9), which is crucial for cell growth and metabolism. They also contain higher levels of Vitamin E, a potent antioxidant.
- Calcium and Potassium: Peanuts contain more calcium and potassium, which support bone health and blood pressure regulation.
Cashew Micronutrient Highlights
- Minerals: Cashews are an excellent source of magnesium, which is vital for nerve function, energy production, and bone density. They also contain significantly more iron, zinc, and copper.
- Antioxidants: Both contain antioxidants, but cashews' content of polyphenols and carotenoids helps protect against oxidative stress.
What About Digestibility and Health?
The quality and digestibility of protein sources are also important. While some research points to cashews having a higher protein digestibility score, peanuts also contain all 20 amino acids, though some are in lower concentrations. Both can be part of a healthy diet, but allergies are a major consideration. Peanuts are one of the most common food allergens, while cashew allergies, a type of tree nut allergy, are also prevalent.
For weight management, both nuts are calorie-dense and should be consumed in moderation. Their high protein and healthy fat content, along with fiber (more in peanuts), contributes to feelings of fullness, helping to curb overall appetite. It's also critical to note that you should never eat cashews in their raw, unshelled form, as they contain a toxic substance called urushiol, which is destroyed during roasting.

Conclusion: Which Should You Choose?
So, what has more protein, cashews or peanuts? Peanuts are the definitive winner on protein per gram. However, the best choice depends on your specific nutritional needs and health goals. If your main objective is maximizing protein intake, peanuts are superior. If you are focused on minerals like magnesium, cashews have a distinct advantage. Both offer heart-healthy fats and can be a filling and nutritious part of a balanced diet when consumed in moderation. Considering the differences in their micronutrient profiles and the varying protein content, incorporating both into your diet could provide the most comprehensive nutritional benefits. Always be mindful of portion sizes due to their high caloric density and be aware of any potential allergies.
Are you looking for the latest information on nut nutrition and trends? Let’s talk about some facts and insights:
- Nutritional Comparison: Peanuts consistently contain more protein per 100g compared to cashews.
- Mineral Advantage: Cashews are richer in essential minerals such as magnesium, iron, zinc, and copper.
- Vitamin Boost: Peanuts offer higher levels of B vitamins and Vitamin E, important for cellular function and antioxidant protection.
- Legume vs. Tree Nut: Peanuts are technically legumes that grow underground, while cashews are seeds from a tree.
- Allergy Risks: Both peanuts and cashews can trigger severe allergic reactions in sensitive individuals, a key health consideration.
- Weight Management: Both can support weight management due to their satiating combination of protein, fat, and fiber, but must be eaten in moderation.
