Every figure is computed from the two foods' USDA values, rounded as printed above. A difference is stated only when it is at least 10% of the larger value and clears a small minimum for the nutrient, so tiny gaps are not dressed up as findings.
Our take
Cooked mushrooms show more carbs and fiber per 100 g than raw, while calories and protein stay in the same range. As with other vegetables, cooking changes the weight, so use the figure that matches the state you weighed.
Raw and cooked values describe different things. Cooking changes how much water a food holds, so the same weight of cooked food carries a different amount of calories and protein than the same weight of raw. Log a food in the state you weighed it.
