What changes the calories
- Mushrooms release a lot of water when cooked, so a cooked portion weighs less than the raw mushrooms it came from, and cooked mushrooms have more calories per gram than raw ones.
- Sautéing or frying adds the calories of the butter or oil they soak up, and mushrooms absorb fat readily, so the cooking fat can easily outweigh the mushrooms themselves.
- Creamy sauces, cheese stuffings and breading add calories well beyond those of the mushrooms.
- Slicing changes how many fit in a cup, which is why 1 cup sliced (70 g) has 15 calories while 1 cup whole (96 g) has 21.
Tips for logging it accurately
- Weigh mushrooms raw before cooking and log that raw weight, since cooked weight shrinks as water cooks off.
- Log any butter, oil or sauce used for cooking as a separate entry, because it usually adds more calories than the mushrooms.
- In BerryFit, you can snap a photo of your mushroom dish and then adjust the portion and add the cooking fat for a more accurate entry.
