What You'll Learn
Mushrooms are low-carb, keto-friendly
Mushrooms are a nutritious food, packed with vitamins, minerals, and antioxidants. They are also low in calories and very low in sodium. Importantly, they are low in carbohydrates, making them a keto-friendly food.
A cup of raw white button mushrooms, for example, contains around 3 grams of carbohydrates. Other common types of mushrooms, such as oyster, shiitake, and portobello, also have a low carb content, with a cup of raw oyster mushrooms containing around 6 grams of carbs, and a cup of raw shiitake mushrooms containing around 7 grams.
The keto diet is a low-carb, high-fat, moderate-protein diet, which means that dieters must restrict their intake of carb-rich foods. As a result, some vegetables, which are often high in carbohydrates, can be unsuitable for a keto diet. However, mushrooms are an exception, as they are naturally low in carbohydrates and can be enjoyed in a variety of ways on a keto diet, both raw and cooked.
Mushrooms are also a source of fibre, which can be difficult to get on the keto diet, as it is typically found in carb-rich foods. In addition, they contain protein and several B vitamins, including riboflavin, niacin, and pantothenic acid, which help the body convert food into energy and reduce tiredness. They are also a source of minerals like selenium, copper, and potassium, as well as vitamin D.
Overall, mushrooms are a keto-friendly food that can be a nutritious and versatile addition to a ketogenic diet.

Carb content varies by mushroom type
Mushrooms are a valuable addition to a healthy eating plan. They are low in calories and packed with essential nutrients. They are also a good source of fibre, vitamins, and minerals. They are known to be one of the low-carb vegetables, making them an excellent option for individuals looking to manage their carbohydrate intake. However, it's important to note that different types of mushrooms may vary slightly in their carbohydrate content.
For instance, a cup of raw mushrooms contains 2.3g of total carbs, while cooked mushrooms (0.5 cups) contain 4.1g of total carbs. The type of mushroom also makes a difference. For example, a single piece of oyster mushroom is said to have 9.52g of total carbs, while a single piece of shiitake mushroom, weighing 19 grams, contains only 1.3g of total carbs.
The variation in carbohydrate content across mushroom types is likely due to their composition of ""whole" carbs and fibre. "Whole" carbs are found in unprocessed foods, including vegetables, whole grains, legumes, and mushrooms. The fibre content in mushrooms contributes to their overall carbohydrate content, which can vary by species.
When considering the carbohydrate content of mushrooms, it's also important to account for their water weight. Mushrooms typically hold a lot of water, and when they dry out, their weight decreases, but their carb content remains the same. This means that the carb content is higher in cooked mushrooms, which have lost water during the cooking process.

Raw vs cooked mushrooms: carb differences
Mushrooms are a nutritional powerhouse, packed with essential vitamins and minerals that benefit our health. They are a good source of B vitamins, selenium, potassium, and vitamin D. While the cooking process does impact the nutritional content of mushrooms, both raw and cooked mushrooms offer unique nutritional advantages.
Raw mushrooms are an excellent source of vitamin C and B vitamins. They also contain polyphenols and flavonoids, which contribute to their antioxidant properties. Additionally, raw mushrooms are lower in carbohydrates, with one cup containing around 2.3g of total carbs and 1g of net carbs.
Cooked mushrooms, on the other hand, offer improved digestibility and enhanced bioavailability of certain compounds. Cooking unlocks powerful antioxidants and increases the absorption of essential minerals. Light cooking methods, such as quick sautéing, offer the best balance by preserving heat-sensitive nutrients while making beneficial compounds more accessible to the body.
The carbohydrate content of cooked mushrooms can vary depending on the cooking method and the initial weight of the raw mushrooms. Cooking methods such as boiling and frying can increase the carbohydrate content, while microwaving and drying have been found to have varying effects on different carbohydrates. For example, 0.5 cups of cooked shiitake mushrooms contain around 10.4g of total carbs and 8.2g of net carbs.
In summary, both raw and cooked mushrooms offer distinct nutritional benefits. Raw mushrooms provide higher levels of certain vitamins and antioxidants, while cooked mushrooms offer improved digestibility and enhanced bioavailability of certain compounds. The best way to maximize the nutritional benefits of mushrooms is to vary the preparation methods, including both raw and cooked mushrooms in the diet.
