What You'll Learn

A cup of raw mushrooms has 15-21 calories
Mushrooms are a type of fungus, distinct from plants and animals, that are often used in cooking as a vegetable. They are a low-calorie food, with a cup of raw mushrooms containing 15-21 calories. This is a low-calorie option, especially as most people do not eat a full cup of mushrooms in one sitting.
Mushrooms are also a good source of copper, potassium, iron, and B vitamins. They contain glutamate ribonucleotides, which add savoury flavour to dishes, and are high in vitamin B, including riboflavin (B2), folate (B9), thiamine (B1), pantothenic acid (B5), and niacin (B3). These vitamins increase the utilization of energy from food and the production of red blood cells, which transport oxygen throughout the body.
Mushrooms are also rich in ergosterol, a vitamin D precursor, making them good for bone health. They contain antioxidants, which have been shown to fight oxidative stress and inflammation, contributing to anti-aging and the prevention of chronic diseases.
Dried mushrooms tend to have more calories than fresh or raw mushrooms because they are more concentrated. When rehydrated, their nutritional value is comparable to raw mushrooms. Canned mushrooms are often higher in calories and significantly higher in sodium due to additives. Fresh mushrooms are available all year round, with their peak season in the United States from April to June.
Cooking mushrooms may destroy some of their nutritional value, with frying and boiling reducing antioxidant activity. Grilling or microwaving mushrooms preserves their nutrients better than these methods.

Cooking methods can change calorie count
Mushrooms are a great option for those looking for a low-calorie, high-fiber food. One cup of raw mushrooms contains just 15 calories, while 100 grams of lion's mane mushrooms contain 24 calories. They are also a good source of copper, B vitamins, potassium, and iron.
While mushrooms are typically low in calories, the calorie count can vary depending on the cooking method used. For example, frying mushrooms can lead to increased fat content and a loss of protein and antioxidants. This is likely due to the leaching of soluble substances in the oil. Boiling mushrooms can also result in a decrease in nutritional value for the same reason. On the other hand, grilling or microwaving mushrooms has been shown to preserve nutrients better than these methods. Grilled portobello mushrooms, for instance, have 35 calories per cup, while a cup of stir-fried white mushrooms has 28 calories.
Dried mushrooms tend to have more calories than raw mushrooms because they are more concentrated. However, when they are rehydrated before cooking or eating, their nutrition is comparable to raw versions. Canned mushrooms are often slightly higher in calories and significantly higher in sodium due to additives.
It is recommended to cook mushrooms before consuming them as their cell walls are made of chitin, which is difficult for humans to digest. Without cooking, it can be hard to absorb the beneficial nutrients that mushrooms provide.

Dried mushrooms have more calories
Mushrooms are a low-calorie food, with one cup of raw mushrooms containing just 15 calories. This makes them a great addition to weight-loss or calorie-conscious diets. They are also a good source of copper, potassium, iron, and B vitamins.
However, dried mushrooms have a higher calorie content than fresh mushrooms. The drying process removes most of the moisture from the mushrooms, resulting in a more concentrated form of the food. This means that dried mushrooms have more calories per gram than fresh mushrooms. For example, a 10-gram serving of dried mushrooms typically contains around 40 calories, while a 10-gram serving of fresh mushrooms would contain less than half that amount.
The higher calorie content of dried mushrooms is due to the concentration of nutrients during the drying process. Dried mushrooms are a good source of carbohydrates, with around 5 grams of carbohydrates per 10-gram serving. They are also a good source of dietary fiber, with 1 gram of fiber per 10-gram serving. Additionally, dried mushrooms are a good source of B vitamins, including thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), and folate (B9).
Despite having more calories, dried mushrooms are still considered a low-calorie food. They are also a valuable source of protein for vegetarians and vegans, with 3 grams of protein per 10-gram serving. The intense flavor of dried mushrooms also makes them a popular ingredient in cooking, as they can add depth and umami to dishes.
In conclusion, dried mushrooms do have more calories than fresh mushrooms due to the concentration of nutrients during the drying process. However, both forms of mushrooms are low-calorie and nutrient-dense, making them a healthy addition to any diet.
