How Many Calories Are in Mushrooms? Unveiling the Nutritional Powerhouse
Mushrooms are incredibly low in calories, making them a fantastic addition to any weight-conscious diet. A typical serving (about 1 cup, sliced) of raw white mushrooms contains only around 15 calories.
The Mushroom’s Nutritional Profile: A Low-Calorie Champion
Mushrooms aren’t just low in calories; they’re also packed with nutrients, offering a range of health benefits. Their unique composition makes them a versatile ingredient for various culinary applications, contributing to a flavorful and balanced diet without adding unnecessary calories. This section will explore the nutritional value of mushrooms and how they can contribute to overall health and well-being.
Understanding Mushroom Varieties and Calorie Counts
The calorie count can vary slightly depending on the type of mushroom. While all mushrooms are generally low in calories, some varieties have marginally higher or lower values due to differences in water content and carbohydrate composition. Let’s look at a few popular types:
Mushroom Type | Serving Size | Calories (approx.) | Notes |
---|---|---|---|
White Button Mushroom | 1 cup, sliced | 15 | The most common type; widely available. |
Shiitake Mushroom | 1 cup, sliced | 40 | Rich in flavor and often used in Asian cuisine. |
Oyster Mushroom | 1 cup, sliced | 28 | Delicate flavor and texture. |
Portobello Mushroom | 1 medium cap | 18 | Meaty texture, often used as a meat substitute. |
Cremini Mushroom | 1 cup, sliced | 19 | Also known as baby bella mushrooms, similar to white button mushrooms. |
These values are estimates, and the actual calorie count may vary slightly depending on the specific mushroom and preparation method.
Beyond Calories: The Nutritional Benefits of Mushrooms
Despite their low-calorie content, mushrooms offer a wealth of nutrients that contribute to overall health. These include:
- B Vitamins: Essential for energy production and nerve function. Mushrooms are a good source of B vitamins like riboflavin, niacin, and pantothenic acid.
- Selenium: An antioxidant that protects cells from damage. Mushrooms are one of the best plant-based sources of selenium.
- Potassium: An electrolyte that helps regulate blood pressure.
- Copper: Important for iron absorption and red blood cell formation.
- Vitamin D: Some mushrooms, when exposed to UV light, produce vitamin D.
- Beta-Glucans: These are a type of soluble fiber that can help boost the immune system and lower cholesterol.
- Antioxidants: Mushrooms contain various antioxidants that protect the body from free radical damage.
Incorporating Mushrooms into a Low-Calorie Diet
Mushrooms are incredibly versatile and can be incorporated into a wide range of dishes. Their umami flavor enhances savory meals, making them a great addition to low-calorie cooking. Here are a few suggestions:
- Soups and Stews: Add sliced mushrooms to soups and stews for added flavor and nutrients.
- Salads: Raw or sautéed mushrooms make a healthy and delicious salad topping.

- Sauces: Blend mushrooms into sauces for a creamy and flavorful addition to pasta or other dishes.
Preparation Methods and Calorie Considerations
While mushrooms themselves are low in calories, the preparation method can significantly impact their caloric content. For example, frying mushrooms in butter or oil will drastically increase their calorie count. Healthy preparation methods include:
- Steaming: Steaming preserves the most nutrients and adds no extra calories.
- Grilling: Grilling adds a smoky flavor without adding extra fat.
- Roasting: Roasting brings out the natural flavors of mushrooms without requiring much oil.
- Sautéing with minimal oil: Use a small amount of olive oil or cooking spray when sautéing mushrooms.
- Microwaving: A quick and easy way to cook mushrooms.
Common Mistakes When Cooking with Mushrooms
- Overcrowding the pan: Overcrowding the pan when sautéing mushrooms will cause them to steam instead of brown.
- Adding salt too early: Adding salt too early can draw out moisture and prevent browning.
- Using too much oil: Excessive oil can add unnecessary calories.
- Not cooking thoroughly: Raw mushrooms can be difficult to digest for some people.
- Washing excessively: Washing mushrooms excessively can make them waterlogged. Gently wipe them clean with a damp cloth instead.

How many calories are in canned mushrooms?
The calorie count in canned mushrooms is usually similar to that of fresh mushrooms, about 15-20 calories per cup. However, be aware of the sodium content, as canned mushrooms often contain added salt. Always read the nutrition label.
Do mushrooms have carbohydrates?
Yes, mushrooms contain carbohydrates, but in relatively small amounts. The carbohydrates in mushrooms are primarily in the form of fiber, which contributes to their nutritional value. A cup of sliced white mushrooms contains around 2-3 grams of carbohydrates.
