About these numbers
The figures come from the USDA FoodData Central entry “Peanuts, all types, dry-roasted, without salt”. They describe the cooked food. Cooking changes the water content, so calories per 100 g differ from the raw food. They are reference averages, so brands, ripeness, cuts and recipes shift the real number. Treat them as estimates, and weigh food for the closest result.
