Calories in walnuts
The nut of the autumn salads of the catalog, dense like all of its family: a handful is a real snack, not a side note.
What a real portion weighs
The Anses table gives values per 100 grams, and 100 grams is not a portion anybody serves. Here are the same values, applied to the portions as they turn up. Weights are in grams, the unit the table is built on. For a quick conversion: 1 oz is about 28 g, and 1 lb is about 454 g.
| Portion | Weight | Energy | Protein | Carbs | Fat | Fiber |
|---|---|---|---|---|---|---|
| A handful of kernels | 30 g | 213 kcal | 4.7 g | 2.1 g | 20.2 g | 2 g |
| One kernel | 4 g | 28 kcal | 0.6 g | 0.3 g | 2.7 g | 0.3 g |
These weights are usual orders of magnitude, not standardized measures: they turn a per-100-gram value into a credible portion. A kitchen scale stays more accurate than any average weight.

What a table of values does not say
- The energy density of nuts comes from their fat, and it is a fat that arrives with fiber and protein: the handful fills a gap, which the number alone does not say.
- The shell is half the weight of a whole walnut: thirty grams of kernels is about fifteen nuts to crack.

What comes after the number
How much to eat in a day
A portion means nothing without the day that holds it. A calorie need is worked out from height, weight, age and activity level, then split into protein, carbohydrate and fat.

An average weight is an estimate. A photo is not.
In Zemiam, a photo of the meal is enough to log the real portion, with the composition of this same table rather than a guessed figure.
Where the values come from
The composition comes from the Anses Ciqual table: Anses. 2025. Table de composition nutritionnelle des aliments Ciqual, published under Licence Ouverte 2.0. The per-100 g values are reproduced without being altered; the per-portion values are those same values multiplied by a weight, and that weight is not an Anses figure.
