Peanuts: nutrition per 100 g and example portion
Reference preparation: plain edible peanuts. The exact source name is “Nut, peanut” (Fineli food 378). Available carbohydrate excludes fiber and is not the same measure as US Total Carbohydrate.
Values are rounded after scaling. A small reported amount may round below 0.1 g; a missing value is marked Not available rather than treated as zero. This selected extract does not include sugar, sodium or micronutrient amounts; the full Fineli database contains information beyond these tables.

| Nutrient | Per 100 g | Per 30 g example |
|---|---|---|
| Energy | 551 kcal | 165 kcal |
| Protein | 25.6 g | 7.7 g |
| Available carbohydrate (excludes fiber) | 12.5 g | 3.8 g |
| Fat | 43 g | 12.9 g |
| Saturated fat | 6.3 g | 1.9 g |
| Fiber | 8.5 g | 2.5 g |
How to weigh peanuts
Weigh peanuts without shells. Peanuts are legumes botanically, but are grouped with nuts here for practical serving comparisons. Salted, honey-roasted and coated peanuts can have different labels, and peanut butter needs its own product entry.
Calculate your own peanuts portion
For the 30 g example, multiply the source amounts by 30 ÷ 100 = 0.3. The unrounded energy calculation is 551.3 × 0.3 = 165.39 kcal, displayed as approximately 165 kcal. Use the same factor for protein, available carbohydrate, fat and fiber.
For another amount, replace 30 with your own edible weight. Keep the preparation as plain edible peanuts; if your food is prepared differently, choose a matching reference or calculate its recipe instead.
How preparation changes the estimate
A peanut sauce includes more than whole peanuts: oil, sugar, coconut milk or soy sauce may be added. Record the full recipe and serving. Peanuts are an allergen; a nut-free or peanut-free meal needs an appropriate ingredient substitution.
Meal ideas using peanuts
Use these combinations as menu ideas and adjust the amounts to your appetite and preferences. Each added ingredient belongs in the complete meal estimate.
