How much protein is in dry brown rice?

Should rice be weighed raw or cooked?

Weigh it in whichever state you log it, and use the row that matches — this page is the raw row. Cooking does not change how many calories are there, only how many grams they are spread across: meat loses water in the pan and gets denser, grains and pasta absorb it and get lighter per gram.

Per serving

The serving sizes USDA lists for this record, priced from the per-100 g figures above. Nothing here is rounded to a “portion” — the gram weight next to each label is what the calories are computed from.

Serving	Weight	Calories	Protein	Fat	Carbs
100 g	100 g	367	7.5 g	3.2 g	76.3 g
1 cup	185 g	679	13.9 g	5.9 g	141.2 g

Compared with other rice

Food	kcal / 100 g	Protein / 100 g	Per serving
Cooked white rice	130	2.7 g	205 kcal · 1 cup

Cooked brown rice	123	2.7 g	248 kcal · 1 cup
Dry brown rice	367	7.5 g	679 kcal · 1 cup

The rice rows exist in more than one state because water moves during cooking: this is the raw row. Weigh the food in the state you log and pick the row that matches — the calories don’t change in the pan, the grams do. The mechanics are in cooked vs raw weights.

How calorie.one logs it

Type “dry brown rice” into calorie.one and the app matches this exact record — “Rice, brown, long-grain, raw (Includes foods for USDA's Food Distribution Program)” — estimates the grams, and shows the line with its USDA label. You correct the amount; the per-100 g figure is never guessed. That split between recognition and arithmetic is the whole methodology.
