How Many Calories Are in a Handful of Peanuts?

A handful (about 30 grams) of roasted, unsalted peanuts contains around 170 calories on average. Botanically, peanuts are legumes, but their calorie and nutrition profile is similar to that of other nuts. Most of their calories come from fat; about half of a peanut's content is fat, making peanuts a concentrated source of energy in a small volume.

Does roasting increase the calories?

There is a noticeable calorie difference between dry-roasted peanuts and those roasted in oil: the oil-roasted kind may have 20–30 more calories in the same handful because the peanuts absorb added oil. Raw peanuts may have a few fewer calories than roasted ones, but the difference is small. The main factor is the oil added during roasting, not the roasting itself.

How do salted and shell-on peanuts differ?

Salted peanuts have nearly the same number of calories as plain peanuts. Salt provides no energy; it only increases the sodium content. Heavily salted packages may encourage people to eat more because of how the flavor affects appetite. Cracking shell-on peanuts yourself slows down eating compared with eating from a ready-to-eat shelled package, which may lead you to eat less while reaching the same feeling of fullness.

How do peanuts compare with other nuts?

Peanuts have slightly fewer calories per gram than almonds and hazelnuts; walnuts are among the highest-calorie nuts. These differences are small, but become noticeable when you eat two handfuls instead of one. Peanut butter is much more calorie-dense than whole peanuts. One tablespoon (15 ml) of peanut butter may have about as many calories as a handful of whole peanuts because processing reduces its volume. Measuring out a handful of peanuts (for example, using a small tea cup) and keeping it ready in a closed container makes it easier to control the portion by sight than snacking directly from the package.

What nutrients do peanuts contain?

Peanuts are rich in protein and fiber; one handful contains about 7 grams of protein and 2.5 grams of fiber. This combination can make peanuts a balanced snack despite their high calorie content. Peanuts also contain vitamin E and minerals such as magnesium. These nutrients do not appear in a calorie count but mean peanuts are more than just a source of empty calories.

When should you eat peanuts?

Eating a handful of peanuts as a light snack between meals is a reasonable way to keep total daily calorie intake under control. However, eating from a package while watching television can easily lead to consuming three or four handfuls. Eating a handful of peanuts just before a meal may somewhat suppress appetite and help you eat less at the main meal, which can indirectly help balance total calories.

Should you consider the risk of an allergic reaction?

Peanuts are among the most common food allergens, so keep this risk in mind when hosting guests or serving food in group settings. Peanuts are a safe source of calories for someone without an allergy, but the risk of cross-contact in shared bowls means it is important to label them or serve them separately.
