About this food

Understanding this nutrition reference

Nori is a thin, dried seaweed sheet made from edible red algae, pressed and roasted. It is best known for wrapping sushi rolls and rice balls, and is also crumbled as a topping or eaten as a crisp snack.

Nutritionally, dried nori is concentrated because the water has been removed. Per 100 g it provides about 250 kcal, 44.1 g of carbohydrates, 26.7 g of protein, and 1.1 g of fat. This reference reflects dried nori sheets.

A single nori sheet weighs only a few grams, so a typical serving provides far less than the per-100 g values. For accurate tracking, weigh the sheets or count them, and use the serving sizes below.
