Dried mushrooms have more calories than raw mushrooms
Mushrooms are a great, low-calorie food option, providing the body with several nutrients, such as copper, potassium, iron, and B vitamins. They are also a good source of antioxidants, which can have several health benefits, such as fighting oxidative stress and inflammation.
When it comes to the calorie content of mushrooms, there are a few factors to consider, including the type of mushroom, its size, and whether it is raw or cooked. On average, one cup of raw mushrooms (about 70 grams) contains 15 calories. This can vary slightly depending on the type and size of the mushroom. For example, four Portabella mushrooms, which are typically larger, contain 74 calories in total.
Cooking mushrooms can affect their calorie content and nutritional profile. According to some sources, cooking mushrooms reduces their calorie content, while increasing their fiber content. For example, raw mushrooms are said to have 3.3 grams of protein per serving, while cooked mushrooms provide only 1.5 grams. Additionally, raw mushrooms are higher in sugar content, with 2.1 grams per serving compared to 1.7 grams in cooked mushrooms.
Dried mushrooms, which are prepared by soaking them in water until they soften, have a higher calorie content than raw mushrooms. This is because the drying process concentrates the calories and nutrients in the mushroom. While specific calorie counts for dried mushrooms are not readily available, it is safe to assume that the calorie content will be higher than that of raw mushrooms due to the loss of water weight during the drying process.
In summary, dried mushrooms do have a higher calorie content than raw mushrooms due to the concentration of nutrients during the drying process. However, mushrooms, in general, remain a low-calorie food option, and the specific calorie count will depend on the type, size, and preparation method of the mushrooms.

Canned mushrooms are higher in calories and sodium than raw mushrooms
Four portabella mushrooms contain 74 calories. However, the number of calories in mushrooms depends on their preparation and cooking method. Fresh mushrooms are always a healthier option as they are low in calories, sodium, carbohydrates, and sugar. They are also high in protein and provide valuable micronutrients.
Canned mushrooms, on the other hand, are higher in calories and sodium. While fresh mushrooms have, on average, 15 calories per cup, canned varieties have significantly higher levels. Canned mushrooms are often imported from countries like China and Vietnam, whereas fresh mushrooms are usually locally sourced.
The higher calorie content in canned mushrooms is due to the canning process, which involves adding salt and other preservatives. These additional ingredients increase the calorie count and alter the nutritional profile of the mushrooms.
Fresh mushrooms are a healthier option for those conscious of their sodium intake. They are naturally low in sodium, making them a better choice for those watching their salt intake. In contrast, canned mushrooms are often soaked in a salty brine solution, resulting in a higher sodium content.
In addition to their lower calorie and sodium content, fresh mushrooms offer a range of nutritional benefits. They are a good source of riboflavin, niacin, copper, pantothenic acid, and selenium.
