One ounce is a snack, one cup is a meal
A 1 oz (28 g) serving of oil-roasted, unsalted peanuts has 168 calories, 7.8 g of protein and 14.7 g of fat. That is roughly a small handful, and it covers 8% of the daily calorie value. The trouble is that peanuts rarely stop at one ounce.
Double it to 2 oz (56 g) and you are at 335 calories. Three ounces (84 g) bring 503, and five ounces (140 g) reach 839, close to a full cup. A 1 cup (144 g) pour carries 863 calories and 75.6 g of fat. That is the size of a full meal, eaten one nut at a time.
If you snack straight from the jar or bag, weigh your usual portion once. Splitting the bag into 1 oz servings keeps the number at 168 instead of drifting toward 503 during a movie.
Fat is nearly three quarters of the calories
Per 100 g, oil-roasted peanuts carry 52.5 g of fat, 28 g of protein and 15.3 g of carbohydrate. In calorie terms that splits into 73% fat, 17% protein and 9% carbs. Peanuts are a fat food that happens to bring real protein, not the other way around.
The protein still counts. One ounce gives 7.8 g, which is 16% of the daily value, and a cup delivers 40.4 g, or 81%. Three ounces (84 g) supply 23.5 g of protein, but that portion also costs 503 calories. On their own, peanuts are a pricey way to chase a protein target.
Saturated fat is modest for such a fatty food: 8.7 g per 100 g out of 52.5 g of total fat. Most of the fat on the label is not the saturated kind, and cholesterol is 0.
Salt depends on the jar, not the peanut
Oil-roasted peanuts without salt have just 6 mg of sodium per 100 g and 2 mg per ounce, which works out to 0% of the daily value. Even a full cup has only 9 mg. Any real sodium comes from what the maker adds.
The dry roasted row shows the gap. One ounce of dry roasted peanuts lists 115 mg of sodium, 5% of the daily value, against 2 mg for the unsalted oil-roasted ounce. Calories barely move: 164 for dry roasted versus 168 for oil-roasted. Dry roasting saves almost nothing in calories; salt is the bigger difference.
Planters sells dry roasted peanuts in salted, lightly salted and unsalted versions, so read the label if you watch sodium. Fiber is the other row worth a look: 2.6 g per ounce and 9.4 g per 100 g, with potassium at 726 mg per 100 g.
Peanuts work best as a measured add-on
At 168 calories an ounce, peanuts fit a day best as a topping or a planned snack rather than an open bag. One ounce over a salad, a stir-fry or yogurt adds crunch, 7.8 g of protein and 2.6 g of fiber for about 8% of the daily calorie value.
Pair them with high-volume, low-calorie foods such as fruit, raw vegetables or a bowl of greens. The peanuts bring fat and protein, the produce brings bulk, and the total stays reasonable. Plain roasted peanuts have only 1.2 g of sugars per ounce, so any sweet or flavored coating changes the label; check it before you log.
If you track, log by weight rather than by handful, since hands vary a lot. BodyPal can also log roasted peanuts from a photo.
How does roasted peanuts compare?
Here is how oil-roasted peanuts stack up against roasted almonds and cashews, per 100 g and per usual serving.
Verdict: Calories are a wash: peanuts have 599 per 100 g, roasted almonds 598 and cashews 574. Pick peanuts for protein, with 28 g per 100 g against 21 g in almonds and 15.3 g in cashews, and for low sodium, with 6 mg against 234 mg and 640 mg.
