A Closer Look at Calories in a Single White Mushroom
For those tracking their nutritional intake, understanding the calorie content of individual food items is key. White mushrooms (Agaricus bisporus), often called button mushrooms, are a staple in many cuisines and are known for being exceptionally low in calories and fat-free. The exact calorie count depends on the size of the mushroom.
According to the U.S. Department of Agriculture (USDA) data, a single raw white mushroom contains the following approximate calorie counts:
- Small Mushroom: About 2 calories.
- Medium Mushroom: Approximately 4 calories.
- Large Mushroom: Around 5 calories.
This minimal caloric contribution makes them an excellent food for adding flavor, texture, and volume to meals without significantly increasing the overall calorie count. Whether you're making a stir-fry, adding them to a salad, or using them as a pizza topping, they are a nutrient-dense option.
The Complete Nutritional Profile
Beyond their low calorie count, white mushrooms offer a host of other beneficial nutrients. They are rich in B vitamins and antioxidants, supporting a healthy lifestyle. Here is a more detailed look at their nutritional makeup based on a 1-cup serving of raw, sliced mushrooms (approximately 70g):
- Protein: ~2.2 grams
- Carbohydrates: ~2.3 grams
- Dietary Fiber: ~0.7 grams
- Total Fat: ~0.24 grams
- Water Content: 93.3%
- Vitamins: Rich in B vitamins like Riboflavin (B2), Niacin (B3), and Pantothenic Acid (B5). They are also a natural, non-fortified plant source of Vitamin D when exposed to UV light.
- Minerals: A good source of Selenium, Copper, Phosphorus, and Potassium.
- Antioxidants: Contain potent antioxidants like ergothioneine and glutathione, which may help protect against cellular damage.
How Cooking Affects Calories and Nutrition
The way you prepare white mushrooms can alter their final calorie content, primarily due to added ingredients rather than the mushroom itself. While boiling has minimal impact on calories, sautéing mushrooms in oil or butter will significantly increase the calorie count. For example, sautéing mushrooms in a tablespoon of olive oil (approx. 120 calories) could add many more calories than the mushrooms themselves contain.
Consider the impact of preparation with this comparison:
Calorie Comparison: Raw vs. Prepared White Mushrooms
| Preparation Method | Added Ingredients | Approximate Calories per 100g | Notes |
|---|---|---|---|
| Raw | None | 22 kcal | Natural, unaltered state. |
| Boiled | None (drained) | 28 kcal | Some nutrients may leach into water, calorie increase minimal. |
| Sautéed | 1 tbsp olive oil | ~142 kcal (22 + 120) | Calorie count heavily depends on amount of fat used. |
| Canned | Brine/Preservatives | ~28 kcal | Calorie content slightly higher due to processing, lower in some nutrients. |
Health Benefits of Incorporating Mushrooms into Your Diet
Adding white mushrooms to your diet is a smart move for more than just calorie control. Their rich nutritional profile contributes to overall wellness. Some of the benefits include:
