The Core Calorie Count: 100g Roasted Peanuts
Roasted peanuts are a popular snack, but their calorie content can vary depending on the roasting method used. A standard 100-gram serving of peanuts provides a substantial amount of energy, primarily from healthy fats and protein. For context, this serving size is about two-thirds of a cup.
Dry-Roasted vs. Oil-Roasted Peanuts
The method of roasting has a direct impact on the calorie count. Dry-roasting, which involves heating the peanuts without adding oil, is the most common preparation method for those looking to minimize added fat and calories.
Dry-Roasted Peanuts: A 100-gram serving of dry-roasted, unsalted peanuts contains approximately 587 calories. The macronutrient breakdown is roughly 71% fat, 14% carbohydrates, and 15% protein. This makes them a calorie-dense but nutrient-rich food.
Oil-Roasted Peanuts: When peanuts are roasted in oil, the calorie count increases slightly. For example, a 100-gram portion of oil-roasted peanuts with salt contains around 599 calories, according to some nutrition databases. The small increase comes from the added fat from the roasting oil.
What About the Salt?
The addition of salt does not add calories to the peanuts but does increase their sodium content. For those managing blood pressure or fluid retention, opting for unsalted roasted peanuts is the healthier choice.
A Comparison of Peanut Varieties
Beyond the roasting method, different types of peanuts can have slight variations in nutritional value. However, for a 100-gram serving, the calorie difference is minimal across most commercially available varieties.

The Nutritional Benefits of Roasted Peanuts
Despite their high calorie count, roasted peanuts are packed with beneficial nutrients that make them a valuable addition to a balanced diet.
- Healthy Fats: Peanuts are rich in monounsaturated and polyunsaturated fats, which are known to promote heart health and help lower bad cholesterol levels.
- Protein Powerhouse: With a high protein content, peanuts contribute to satiety, muscle repair, and growth. This makes them an excellent snack for athletes and those seeking to manage their weight.
- Fiber: The dietary fiber in peanuts aids digestion and helps you feel full longer, which can prevent overeating.
- Vitamins and Minerals: Peanuts are a good source of vitamins like niacin (B3) and folate (B9), and minerals such as magnesium, manganese, and potassium.
- Antioxidants: They contain powerful antioxidants like resveratrol, which have anti-inflammatory properties and can help protect against chronic diseases. For more information on the antioxidants in peanuts, consult the National Institutes of Health research archives.
How to Include Roasted Peanuts in Your Diet
Given their energy density, portion control is key when eating roasted peanuts. A handful (about 28-30 grams) is a reasonable serving size and provides about 165-180 calories.
- Snack Smart: Instead of grabbing a large bag, portion out a small amount into a bowl. This helps you monitor your intake.
- Add to Meals: Sprinkle chopped roasted peanuts on salads or stir-fries for a crunchy texture and nutritional boost.
- Homemade Peanut Butter: Make your own fresh peanut butter in a food processor using dry-roasted, unsalted peanuts. This allows you to control the ingredients and avoid added sugars.
- Baking: Use roasted peanuts as a filling or topping for baked goods like cookies and muffins.

In summary, 100 gm of roasted peanuts contains a significant number of calories, ranging from approximately 587 kcal for dry-roasted, unsalted varieties to slightly more for oil-roasted versions. While high in energy, their rich content of protein, healthy fats, fiber, and essential nutrients makes them a beneficial snack when consumed in moderation. Paying attention to preparation methods and portion sizes will ensure you reap their nutritional rewards without undermining your health goals.
