Cashew Nutrition: Calories, Protein, Fats & Benefits
Cashews are one of the most popular nuts worldwide, and for good reason. They taste great, blend into almost anything, and deliver an impressive nutritional profile. But how many calories are in cashews? How much protein do they actually contain? And are the fats in cashews the healthy kind?
This guide covers everything you need to know about cashew nutrition, from macronutrient breakdowns to specific vitamin and mineral content, practical serving sizes, and evidence-based health benefits.
Cashew Nutrition Facts: The Full Breakdown
Here is the nutritional profile of cashews per 30-gram serve (roughly 18 whole cashews) and per 100 grams:
| Nutrient | Per 30g Serve | Per 100g |
|---|---|---|
| Energy | 720 kJ (172 cal) | 2,400 kJ (574 cal) |
| Protein | 5.4g | 18.2g |
| Total Fat | 13.1g | 43.8g |
| Saturated Fat | 2.6g | 8.6g |
| Monounsaturated Fat | 7.3g | 24.4g |
| Polyunsaturated Fat | 2.3g | 7.8g |
| Carbohydrates | 8.9g | 29.7g |
| Fibre | 1.0g | 3.3g |
| Sugar | 1.7g | 5.9g |
Cashews are lower in fat than most other nuts (almonds, macadamias, and walnuts all contain more fat per serve), which makes them a moderate-calorie nut option. They also have the highest carbohydrate content among popular nuts, giving them a slightly more balanced macronutrient profile.
Cashew Calories: How Many Are in a Serve?
A single cashew contains roughly 9 to 10 calories (38 to 42 kJ). Ten cashews come in at approximately 95 to 100 calories. A standard 30-gram handful provides about 172 calories (720 kJ).
For context, that is comparable to a medium banana or a small tub of natural yoghurt. Cashews are calorie-dense, but they are also highly satiating because of their protein and fat content. Studies consistently show that nut consumption does not lead to weight gain when eaten in recommended portions, largely because nuts increase satiety and reduce overall calorie intake at subsequent meals.
Cashew Protein Content
Cashews provide 18.2 grams of protein per 100 grams, making them a solid plant-based protein source. A 30-gram serve delivers 5.4 grams of protein, which is roughly equivalent to one egg white.
While cashews do not contain all essential amino acids in optimal ratios (they are relatively low in lysine), pairing them with legumes, grains, or other protein sources throughout the day easily covers any gaps. For vegetarians and vegans, cashews are a valuable part of the protein puzzle.
How Cashew Protein Compares to Other Nuts
| Nut (per 30g) | Protein | Calories |
|---|---|---|
| Cashews | 5.4g | 172 cal |
| Almonds | 6.3g | 176 cal |
| Pistachios | 6.0g | 168 cal |
| Walnuts | 4.6g | 196 cal |
| Macadamias | 2.4g | 215 cal |
Cashews sit in the middle of the pack for protein density, but they have a distinct advantage in taste and texture. Their creamy, buttery flavour makes them one of the most versatile nuts for cooking, baking, and snacking.
Fats in Cashews: Are They Healthy?
About 75% of the fat in cashews is unsaturated, with the majority being monounsaturated fat (oleic acid). This is the same type of fat found in olive oil and avocados, and it is strongly associated with reduced cardiovascular risk.
The fat profile of cashews breaks down as follows: monounsaturated fats make up roughly 60% of total fat, polyunsaturated fats account for about 18%, and saturated fats represent approximately 22%. This ratio is considered heart-healthy by most nutritional guidelines.
Research published in major nutrition journals has repeatedly linked regular nut consumption with lower LDL cholesterol, reduced inflammation, and improved arterial function. The National Heart Foundation of Australia recognises a 30-gram serve of nuts (including cashews) as part of a heart-healthy eating pattern.
Key Vitamins and Minerals in Cashews
Beyond macronutrients, cashews are packed with essential micronutrients:
- Copper: Cashews are one of the richest food sources of copper, providing over 60% of your daily needs per 30g serve. Copper supports immune function, iron metabolism, and connective tissue formation.
- Magnesium: Each serve provides roughly 20% of daily magnesium needs. Magnesium is crucial for muscle and nerve function, blood sugar regulation, and bone health.
- Zinc: Essential for immune function, wound healing, and protein synthesis. A 30g serve delivers about 15% of daily requirements.
- Phosphorus: Important for bone and teeth formation. Cashews provide around 15% of daily needs per serve.
- Iron: Cashews contain non-haem iron, which is important for vegetarian and vegan diets. Pairing cashews with vitamin C-rich foods improves iron absorption.
- Vitamin K: Plays a role in blood clotting and bone metabolism.
Evidence-Based Health Benefits of Cashews
Heart Health
The monounsaturated and polyunsaturated fats in cashews help lower LDL ("bad") cholesterol while maintaining or increasing HDL ("good") cholesterol. The magnesium content also supports healthy blood pressure levels.
Blood Sugar Management
Despite being a nut with relatively higher carbohydrate content, cashews have a low glycaemic index. The combination of protein, fat, and fibre slows carbohydrate digestion, helping to moderate blood sugar responses after meals.
Bone Health
Cashews provide magnesium, phosphorus, and copper, all of which play roles in bone formation and maintenance. Adequate magnesium intake is particularly important because about 60% of the body's magnesium is stored in bones.
Immune Support
The zinc and copper in cashews both support immune system function. Zinc is involved in the development of immune cells, while copper helps maintain the health of white blood cells.
How Many Cashews Should You Eat Per Day?
The recommended daily serve of nuts in Australia is 30 grams, which equals about 15 to 18 whole cashews. This amount provides a strong nutritional boost without excessive calorie intake.
Eating more than 30 grams is not harmful, but the calorie density means that larger portions should be factored into your overall daily energy intake. For most people, a single 30-gram serve of cashews (or a mix of different nuts) is the sweet spot.
Roasted vs Raw Cashews: Does It Matter?
Raw and roasted cashews have very similar nutritional profiles. Dry roasting slightly reduces water content and can marginally increase the concentration of certain nutrients. Oil-roasted cashews add a small amount of extra fat from the cooking oil.
The bigger distinction is flavouring. Plain roasted cashews are nutritionally almost identical to raw ones. Flavoured or seasoned cashews may add sodium, sugar, or other ingredients, so always check the label. Spice-roasted cashews (such as butter chicken or vindaloo varieties) use dry spice blends that add flavour without significant additional calories.
Common Mistakes When Eating Cashews
- Not portioning. Cashews are easy to overeat. Measure a 30-gram serve or choose pre-portioned packs.
- Choosing sugar-coated varieties. Honey-roasted or caramelised cashews can double the sugar content. Opt for plain or spice-roasted instead.
- Dismissing cashews as "too fatty." The fats in cashews are predominantly heart-healthy monounsaturated fats. They are not the same as the saturated fats in processed foods.
- Storing improperly. Cashews can go rancid if exposed to heat, light, or air. Keep them sealed in a cool, dark place.
Frequently Asked Questions
How many calories are in 10 cashews?
Approximately 95 to 100 calories (400 to 420 kJ). Individual cashew size varies, so this is an estimate.
Are cashews good for weight loss?
In moderation, yes. The protein and healthy fat content promotes satiety, which can reduce overall calorie intake. Studies show that regular nut consumers tend to have healthier body weights than non-consumers.
Are cashews a good source of protein?
Cashews provide 18.2g of protein per 100g, making them a solid protein contributor, especially for plant-based diets. A 30-gram serve delivers 5.4g of protein.
Which is healthier: cashews or almonds?
Both are excellent choices. Almonds have slightly more protein, fibre, and vitamin E. Cashews have more copper, zinc, and iron. The best approach is to eat a variety of nuts.
