About these numbers
The figures come from the USDA FoodData Central entry “Mushrooms, white, raw”. They describe the raw food. Cooking changes the water content, so calories per 100 g will differ once it is cooked. They are reference averages, so brands, ripeness, cuts and recipes shift the real number. Treat them as estimates, and weigh food for the closest result.
