What You'll Learn
Carb content of raw mushrooms
Mushrooms are low in carbohydrates and keto-friendly in their raw, natural form. The carbohydrate content of raw mushrooms varies depending on the type of mushroom and how they are measured.
Common types of mushrooms, such as white button, shiitake, oyster, and portobello, are all considered to be low in carbohydrates. For example, a 1-cup (96-gram) serving of raw, whole white button mushrooms contains 3 grams of carbohydrates. A cup of raw oyster and shiitake mushrooms contains around 6 and 7 grams of carbohydrates, respectively. Similarly, a 1-cup (86-gram) serving of diced portobello mushrooms or an average mushroom cap contains around 3 grams of carbohydrates.
When measuring the carbohydrate content of raw mushrooms, it is important to consider their water content. Mushrooms are composed of about 80-90% water, which can affect the carb content when they are cooked. For example, 100 grams of raw mushrooms may lose water during cooking and result in 100 grams of cooked mushrooms with a higher carb content per gram. Therefore, it is recommended to refer to the nutrition labels of packaged mushroom products and use the carb content information for raw mushrooms when weighing them before cooking.
Overall, the carb content of raw mushrooms typically ranges from 0.3 grams per 100 grams to 2.3 grams per cup, depending on the specific type of mushroom and measurement used.

Carb content of cooked mushrooms
Mushrooms are low in carbohydrates and keto-friendly in their natural form. The carbohydrate content of cooked mushrooms depends on the type of mushroom and the quantity. For instance, a 1-cup (96-gram) serving of raw, whole white button mushrooms contains 3 grams of carbohydrates, but when cooked, the carb content will be higher per 100 grams of mushrooms due to the loss of water during cooking.
Oyster mushrooms and shiitake mushrooms are also low in carbohydrates, with a 1-cup serving of raw mushrooms containing around 6 and 7 grams of carbs, respectively. Portobello mushrooms contain around 3 grams of carbs per cup, whether diced or left as a cap. When cooked, the carb content of these mushrooms will also be higher per 100 grams due to water loss, similar to white button mushrooms.
Cooked mushrooms (0.5 cup) contain approximately 4.1 grams of total carbohydrates, 1.7 grams of net carbs, 0.4 grams of fat, 1.7 grams of protein, and 22 calories. In comparison, raw mushrooms (1 cup) contain 2.3 grams of total carbs, 1 gram of net carbs, 0.2 grams of fat, 2.2 grams of protein, and 15 calories.
It is important to note that the nutritional values may vary slightly depending on the specific type of mushroom, the cooking method, and the serving size. Additionally, canned or packaged mushroom products may have different nutritional values, so it is always a good idea to check the nutrition labels.

Carb content of canned mushrooms
Mushrooms are low in carbohydrates and keto-friendly in their natural form. Common types like white button, shiitake, oyster, and portobello contain a small number of carbs. For instance, a 1-cup (96-gram) serving of raw, whole white button mushrooms contains 3 grams of carbs, while a cup of raw oyster and shiitake mushrooms contains around 6 and 7 grams of carbs, respectively.
However, the carb content of canned mushrooms is slightly higher. One source states that a 1-cup serving of canned mushrooms contains 7.9 grams of total carbs, 4.2 grams of net carbs, 0.5 grams of fat, 2.9 grams of protein, and 39 calories. Another source highlights that canned mushroom products may not be keto-friendly, as they can contain added ingredients that increase the carb content. For example, a 1/2-cup serving of Campbell's Cream of Mushroom prepared soup contains 8 grams of carbs, and there are 2.5 servings per can, contributing to a total of 20 grams of carbs.
It's important to note that the carb content of mushrooms can vary depending on the specific variety, the amount consumed, and whether they are raw or cooked. Mushrooms hold a lot of water, and when they dry out, they weigh less, but the carb content relative to the same amount of fresh mushrooms remains the same. Therefore, it's recommended to refer to the nutrition labels on canned mushroom products and use the numbers provided for raw mushrooms when cooking.
Overall, while mushrooms are generally low in carbs, the processing and added ingredients in canned mushrooms can increase their carb content, so it's advisable to check the labels to make an informed choice.

Nutritional benefits of mushrooms
Mushrooms are a nutritional powerhouse, packed with vitamins, minerals, and antioxidants. They are a good source of vitamin D, especially when exposed to ultraviolet light, making them the only natural source of vitamin D in the produce aisle. Vitamin D is essential for bone and immune health, and mushrooms also contain selenium, which helps to maintain a healthy immune system by preventing cell damage.
Mushrooms are also rich in B vitamins, including riboflavin, niacin, and pantothenic acid. These vitamins help protect heart health, support the nervous system, and provide energy by breaking down proteins, fats, and carbohydrates. Niacin is beneficial for the digestive system and healthy skin, while riboflavin and pantothenic acid play a role in hormone production.
In addition, mushrooms are a good source of potassium, which is important for heart, muscle, and nerve function. Potassium also helps to reduce blood pressure by lessening the tension in blood vessels. Mushrooms are low in sodium, fat-free, low-calorie, and nutrient-dense, making them a healthy addition to any diet.
Common varieties such as white button, shiitake, oyster, and portobello are naturally low in carbohydrates, making them suitable for keto diets. For example, a 1-cup serving of raw white button mushrooms contains around 3 grams of carbohydrates. Mushrooms are versatile and can be enjoyed raw or cooked in a variety of dishes, adding both flavour and nutritional benefits to one's diet.
