How Nut Size Affects the Count
Variations in cashew size impact the number of nuts in a 28-gram serving. Cashews are graded commercially based on the kernel count per pound. For example, W320 cashews are smaller, requiring about 320 nuts per pound, while W180 cashews are larger, with approximately 180 nuts per pound. This grading system directly impacts the number of nuts received for the same weight. A 28-gram portion of smaller, more common W320 cashews will contain more nuts than the same portion of larger, king-sized W180 cashews.
The Standard 28-Gram (1 oz) Serving
A 28-gram portion is the standard serving size for nuts, as defined by health organizations like the USDA. This quantity is used to calculate the nutritional information on most food labels. It is a key reference for anyone tracking nutrient intake, as it balances the health benefits of cashews with their high caloric density. Adhering to this serving size helps ensure a good dose of minerals without over-consuming calories, which is important for weight management.
Nutritional Profile of 28 Grams of Cashews
A 28-gram serving of unroasted, unsalted cashews provides many important nutrients.
- Calories: Approximately 157 kcal, mostly from heart-healthy unsaturated fats.
- Fat: Around 12.4 grams of fat, with a balanced ratio of monounsaturated and polyunsaturated fats.
- Protein: About 5.16 grams, providing a solid plant-based protein boost.
- Fiber: Close to 1 gram, which aids digestion and satiety.
- Minerals: Excellent source of copper (0.6 mg), magnesium (82.8 mg), and manganese (0.4 mg).
Cashews vs. Other Popular Nuts: A Nutritional Comparison
Different nuts have varying nutritional profiles, even in the same standard serving size. Here is a table comparing a 28-gram serving of cashews with other common nuts like almonds and walnuts.
| Nutrient (per 28g) | Cashews | Almonds | Walnuts |
|---|---|---|---|
| Calories (kcal) | ~157 | ~164 | ~185 |
| Fat (g) | ~12.4 | ~14.6 | ~18.5 |
| Protein (g) | ~5.16 | ~6 | ~4.3 |
| Fiber (g) | ~0.9 | ~3.5 | ~1.9 |
| Copper (mg) | ~0.6 | ~0.3 | ~0.4 |
| Magnesium (mg) | ~82.8 | ~76 | ~45 |
| Omega-3s | Absent | Trace amounts | High content |
This comparison shows that while cashews are a fantastic source of minerals like magnesium and copper, other nuts may offer more fiber (almonds) or essential fatty acids like omega-3s (walnuts).
Practical Tips for Mindful Snacking
Knowing that approximately 18 cashews make up a 28-gram serving is a useful tool for portion control. Instead of mindless snacking, pre-portion snacks. Placing a small handful of cashews into a container allows for a mindful and controlled snack. Pairing cashews with other foods like fruit or a low-fat dairy item can also enhance satiety, preventing overconsumption of high-calorie nuts. Additionally, opting for raw or dry-roasted, unsalted versions is always the healthier choice over oil-roasted or flavored varieties, which add unnecessary calories and sodium.
Conclusion
For a standard 28-gram serving, expect around 18 whole cashews, though this number can vary depending on nut size grade. Understanding this serving size is essential for managing caloric intake while enjoying cashews' flavor and health benefits. By pre-portioning and being mindful of cashew size and processing, this nutritious snack can be integrated into a balanced diet without overdoing it. Cashews are a versatile and delicious choice that, when eaten in moderation, can contribute to overall health and wellness.

Can roasted cashews affect the count?
Roasting cashews typically does not change their weight significantly enough to alter the nut count in a 28-gram serving, but oil-roasted versions will have more calories than dry-roasted or raw cashews. The count remains similar, but the nutritional value changes.
How does cashew grade (W320, W180) affect the count?
The grade refers to the number of kernels per pound. A lower grade number, like W180, means larger, heavier nuts, so fewer will fit into a 28-gram serving. A higher number, like W320, indicates smaller nuts, meaning more cashews for the same weight.
