Carbohydrate content varies by species
Mushrooms contain carbohydrates, but their carb content is generally low. They are considered whole carbs, which are found in unprocessed foods that still contain natural fibre. The amount of carbs in mushrooms varies depending on the species. For example, a cup of whole white button mushrooms weighing 96 grams contains 3.1 grams of carbohydrates. In contrast, a single oyster mushroom is said to have 9.52 grams of total carbs, while a single Portabella mushroom contains 4.26 grams. Shiitake mushrooms have a lower carb content, with a single piece weighing 19 grams containing 1.3 grams of total carbs. When cooked, 0.5 cups of shiitake mushrooms yield 10.4 grams of total carbs and 8.2 grams of net carbs.
The variation in carbohydrate content across mushroom species means that some types are more suitable for low-carb diets than others. Mushrooms are a good source of fibre and protein and can be a nutritious addition to a balanced diet. They also contain various other nutrients, including copper, potassium, selenium, and B vitamins such as folate, niacin, and riboflavin. Additionally, certain types of mushrooms, like dried shiitake, are a source of selenium, an essential mineral that contributes to normal immune function.
The keto diet, a popular low-carb, high-fat, and moderate-protein regimen, includes mushrooms as a keto-friendly food. This is because mushrooms have a naturally low carbohydrate and fat content, making them a versatile and nutritious ingredient for those following the keto diet or aiming for weight loss.

Mushrooms are not considered a starchy food and do not have the same effects as grains, potatoes, or beans. They are classified as a non-starchy vegetable, so they are fine to consume on the keto diet.
The amount of carbohydrates in mushrooms varies depending on the species. For example, a cup of whole white button mushrooms weighing 96 grams contains 3.1 grams of carbohydrates, while a single oyster mushroom is said to have 9.52 grams of total carbs. Most of the carbohydrates in mushrooms are in the form of dietary fiber, which has been linked to maintaining a healthy body weight and decreasing the risk of chronic disease. Mushrooms are also a good source of vitamins and minerals, making them a valuable addition to any diet.
Mushrooms are a versatile ingredient that can be added to a variety of dishes without significantly impacting carb intake. They can be sautéed as a side dish, added to stir-fries, or used as a meat substitute in dishes like mushroom risotto.

For instance, they have been linked to antioxidant, anti-inflammatory, and anticancer effects.
The keto diet involves significantly reducing carbohydrate intake and increasing fat intake. Mushrooms, being low in carbs and high in fibre, make an excellent addition to this diet. They can be used as a meat substitute or added to various dishes, providing a delicious umami flavour without significantly impacting carb intake.

Mushrooms are a source of fibre
Mushrooms are a nutrient-dense food, containing various vitamins and minerals, including copper, potassium, selenium, and B vitamins like folate, niacin, and riboflavin. They also contain non-nutritive substances such as polysaccharides, indoles, polyphenols, and carotenoids, which have been shown to have antioxidant, anti-inflammatory, and anticancer effects in cell and animal studies.
The fibre content in mushrooms makes them a suitable food for low-carb diets, such as the keto diet. They are also a good option for weight loss due to their low-calorie content. For example, 100 grams of white mushrooms contain only 22 calories. Additionally, mushrooms are a source of protein and can be used as a versatile ingredient in various meals.
While mushrooms do contain carbohydrates, they are not an essential nutrient for human health. The body does not require carbohydrates to function and can use ketones from fat for energy. However, many nutritious whole foods provide carbohydrates, and mushrooms are included in this category.

Mushrooms are a source of vitamin D
Mushrooms are a good source of vitamin D. They are the only significant source of vitamin D in the produce aisle, as no other fruits and vegetables contain enough of the nutrient to be considered beneficial. The vitamin D in mushrooms is in the form of vitamin D2, which is also found in other fungi and yeast. Vitamin D3, on the other hand, is found in animal sources, with vitamin D3 being the most common form in animal foods.
Mushrooms contain a compound called ergosterol, which is converted into vitamin D when exposed to UV light. This process happens naturally when mushrooms grow in the wild and are exposed to sunlight. Commercially grown mushrooms, on the other hand, are often grown in the dark and lack vitamin D. However, some growers use ultraviolet light to produce vitamin D-rich mushrooms.
The amount of vitamin D2 in mushrooms can be increased by exposing them to UV radiation from a UV lamp or sunlight. The concentration of vitamin D2 depends on factors such as the type and orientation of the mushrooms, whether they are sliced or whole, and the distance from the light source. Vitamin D is a highly impactful nutrient for people of all ages, and it is essential for bone formation and the proper functioning of organs and tissues in the body.
Mushrooms are a good source of vitamin D for vegans and vegetarians, as they are the only non-animal food product with substantial amounts of bioavailable vitamin D. They can help individuals who are vitamin D deficient increase their intake, as recommended by Colorado State University. Mushrooms are a nutritious food that provides not only vitamin D but also other important nutrients such as selenium, fiber, and B-vitamins.
