Dietitian's Tips for Consuming Hazelnut (Roasted)

For dry-roasted hazelnuts without added salt, a 15 g portion provides about 97 kcal, while 30 g provides 194 kcal. Oil-roasted, salted and sugar-coated varieties need different nutrition information.

Counts and handfuls

A 30 g serving contains about 4.51 g protein, 18.72 g fat and 2.82 g fibre. Nut size varies, so “ten hazelnuts” or “a handful” does not always represent the same weight. Weighing your usual portion once makes later comparisons easier to understand.

Set aside and weigh a small bowlful before eating from a large packet to make your portion easier to count.

When comparing with raw hazelnuts, use shelled kernels at equal weights; a labelled roasted product should be counted from its own panel.

For salted roasted hazelnuts, compare the salt line as well as an equal weight. That generic 30 g example gives about 0.57 g salt equivalent; it is separate from this plain-kernel reference.

Ground hazelnuts still come from the same nuts

Crushing or grinding hazelnuts does not remove their energy. For example, dividing 15 g of roasted hazelnuts equally between four desserts adds about 24 kcal from hazelnuts to each. The remaining dessert ingredients are counted separately.

Use a separate label when replacing plain roasted hazelnuts with hazelnut spread: the spread may contain sugar, cocoa or other fats. Hazelnut allergens apply.

The 16% hazelnut declaration on double-roasted hazelnut chocolate describes only part of the product. Do not log the whole chocolate weight as plain roasted nuts.

Source note

Figures come from USDA SR28 entry 12122. Zero sodium is an actual reported value for this unsalted reference, not a substitute for missing data. Raw and salted-hazelnut values have not been mixed into it.
