Carbohydrate content: One cup of raw mushrooms contains 2.3 grams of carbohydrates
Mushrooms are a nutritious food that provides a good amount of fibre, vitamins, and minerals. They are also a source of carbohydrates, albeit a small one. Carbohydrates come primarily through fibre, and one cup of raw mushrooms contains 2.3 grams of carbohydrates. This amount varies slightly by species, with white button mushrooms containing 3.1 grams of carbohydrates per cup, and oyster, portabella, and shiitake mushrooms containing 9.52, 4.26, and 1.3 grams of carbohydrates, respectively.
Mushrooms are also a natural, non-animal source of vitamin D2, as exposure to UV rays or sunlight increases their vitamin D content. They are rich in antioxidants, including glutathione and ergothioneine, which have been shown to fight oxidative stress and inflammation, contributing to anti-aging and the prevention of chronic diseases. Additionally, the ergothioneine and beta glucan in white mushrooms may help reduce the risk of heart disease by lowering blood cholesterol levels.
Beta glucan, a type of soluble fibre, forms a gel-like substance when digested, trapping triglycerides and cholesterol to prevent their absorption. Polysaccharides, another bioactive compound in white mushrooms, may have anticancer effects by stimulating the immune system to activate macrophages and natural killer cells, which protect the body from harmful organisms and diseases, including cancer.
Mushrooms are also a good source of micronutrients, including copper, potassium, phosphorus, and iron. They have a low-fat content, with most of it being polyunsaturated fat, and are considered a heart-healthy food choice. Overall, mushrooms are a nutritious food with a range of potential health benefits.

White button mushrooms: A cup of whole white button mushrooms (96 grams) contains 3.1 grams of carbs
White button mushrooms, also known as table, common, or champignon mushrooms, are a popular variety of edible fungi. They have a mild flavour and a smooth cap, making them a versatile ingredient in various dishes. But do button mushrooms contain carbohydrates?
Indeed they do. A cup of whole white button mushrooms (approximately 96 grams) contains 3.1 grams of carbohydrates. This amount is relatively low compared to other foods, and it's important to note that the type of carbohydrates found in mushrooms is primarily through fibre, specifically soluble fibre like beta-glucan. Beta-glucan has been shown to have beneficial effects on heart health by lowering blood cholesterol levels.
Additionally, white button mushrooms are a good source of other essential nutrients. They contain antioxidants like glutathione and ergothioneine, which can help fight oxidative stress and inflammation in the body. These antioxidants are not commonly found in many plant foods, making mushrooms a valuable source. White button mushrooms are also a source of vitamin D, especially when exposed to UV rays or sunlight during cultivation.
When it comes to micronutrients, white button mushrooms provide copper, potassium, phosphorus, and iron. They also contain small amounts of protein and fat, with one cup offering around 2.2 grams of protein and only 0.2 grams of fat. Overall, white button mushrooms are a nutritious food choice, offering a range of health benefits beyond their modest carbohydrate content.

Other varieties: Carb content varies by species, with oyster, portabella, and shiitake mushrooms having higher levels
The carb content of mushrooms varies across different species. Oyster mushrooms, for instance, contain 5.2g of total carbs per raw cup, offering relatively fewer carbs compared to other varieties. Cooking reduces this amount, with half a cup of cooked oyster mushrooms containing 3g of net carbs.
Portabella mushrooms, on the other hand, provide 2.7g of total carbs and 0.8g of net carbs per half-cup serving when cooked from fresh. This makes them a relatively lower-carb option, especially considering their other nutritional benefits, such as protein and low-fat content.
Shiitake mushrooms have a higher carb content, with a cooked serving of half a cup containing 10.4g of total carbs and 8.2g of net carbs. This makes them a more significant source of carbohydrates compared to the previously mentioned varieties.
While button mushrooms are not specifically mentioned in the search results, it is evident that the carb content varies considerably between different mushroom types. Oyster, portabella, and shiitake mushrooms each offer distinct carb levels, influencing their suitability for various dietary needs and preferences.

Health benefits: Mushrooms are low in calories, fat, and carbs, and are a good source of fiber and vitamins
Mushrooms are a healthy food choice due to their low-calorie, low-fat content, and the presence of modest amounts of fiber and various nutrients. One cup of raw mushrooms contains 2.3 grams of carbohydrates, 2.2 grams of protein, and 0.2 grams of fat. Fried button mushrooms, on the other hand, have a higher calorie count and more carbohydrates, with 178 calories and 30 grams of carbs per 1/4 pound serving.
White button mushrooms, also known as table, common, or champignon mushrooms, are a type of white mushroom. They are low in calories and contain various beneficial compounds. The main phenolic compounds in white mushrooms are flavonoids and phenolic acids, which act as antioxidants and pro-oxidants. As antioxidants, they improve cell survival, while as pro-oxidants, they induce cell death to prevent tumor growth. White button mushrooms are also rich in ergothioneine, which may help reduce triglyceride levels in the blood.
Mushrooms are a good source of fiber, particularly the soluble fiber beta-glucan, which has additional health benefits. Beta-glucan is a type of fiber that lowers blood cholesterol levels by forming a gel-like substance in the digestive system. This gel traps cholesterol and triglycerides, preventing their absorption into the body. As a result, mushrooms are considered a heart-healthy food choice.
Mushrooms are also a source of important vitamins and minerals, including vitamin C, vitamin B6, magnesium, phosphorus, potassium, copper, folate, and zinc. Some mushrooms, such as white button mushrooms, are high in the antioxidants glutathione and ergothioneine, which are not commonly found in plant foods. These mushrooms may be treated with UV light to increase their vitamin D content, making them an excellent source of this nutrient.

Preparation: Carb content may vary depending on how button mushrooms are prepared, e.g., fried button mushrooms have 30g of carbs
The carbohydrate content of button mushrooms can vary depending on how they are prepared. For example, fried button mushrooms have 30 grams of carbohydrates per serving, which is significantly higher than the 3.1 grams of carbohydrates in one cup of raw whole white button mushrooms.
Button mushrooms are a type of mushroom that is commonly used in cooking and are known for their small, round shape and delicate flavour. They are considered a healthy food choice due to their low-calorie content and the fact that they contain several important nutrients.
While the exact carbohydrate content of button mushrooms can vary depending on the specific variety and growing conditions, they are generally considered to be a good source of whole carbs, which are found in the natural fibre of the mushroom. Whole carbs are different from refined carbs, which have been linked to obesity and other health issues.
The method of preparation can significantly impact the carb content of button mushrooms. For example, frying button mushrooms in batter can add additional carbohydrates from the flour and other ingredients used in the batter. Similarly, adding breading or other coatings to button mushrooms before cooking can also increase the overall carb content of the dish.
It's important to note that the carb content of fried button mushrooms can also vary depending on the specific recipe and cooking method used. The values mentioned above are based on a particular serving size and may not be representative of all fried button mushroom recipes. Additionally, the carb content of button mushrooms can also be affected by the other ingredients used in the dish, such as sauces or seasonings, which can add to the overall carb count.
