The keto diet is a low-carb, high-fat, moderate-protein diet that aims to limit carbohydrate intake to 50 grams or fewer per day to achieve and maintain a state of ketosis, where the body uses ketone bodies as its primary source of energy. Mushrooms are a nutrient-dense food that can complement a balanced diet, whether keto or otherwise. They are naturally low in carbohydrates, with common types like white button, shiitake, oyster, and portobello containing 2-4 grams of carbs per 100 grams. This makes mushrooms a keto-friendly food that can be enjoyed raw or cooked in various dishes. However, canned or packaged mushroom products may be higher in carbs, so it is essential to read nutrition labels.

Mushrooms are a great addition to a keto diet because they are low in carbohydrates and delicious. They are also a good source of fibre and protein, making them a versatile ingredient for a variety of meals. Common types of mushrooms, like white button, shiitake, oyster, and portobello, are low in carbohydrates and keto-friendly in their natural form.

A cup of raw oyster and shiitake mushrooms contains around 6 and 7 grams of carbs, respectively.
It is important to note that while mushrooms are keto-friendly, the way you prepare them and the other ingredients you use can affect their carb content. For example, if you are using canned or packaged mushroom products, it is important to read the nutrition label as these may not be as keto-friendly due to the added ingredients. Additionally, cooking mushrooms may affect their carb content, as the water content decreases, resulting in a higher concentration of carbs per gram. However, the total carb content remains relatively the same.
Overall, mushrooms are a keto-friendly food due to their low carbohydrate content, and they can be enjoyed in various dishes while following a keto diet.

Common mushroom varieties such as white button, portobello, oyster and shiitake are low in carbs
Mushrooms are a keto-friendly food, as they are low in carbohydrates. The keto diet is a low-carb, high-fat diet that restricts carbohydrate intake to 50 grams or fewer per day. This diet is designed to help the body achieve and maintain a state of ketosis, where it uses ketone bodies instead of glucose as its primary energy source.
Common mushroom varieties such as white button, portobello, oyster, and shiitake are low in carbs and keto-friendly in their natural form. For example, a 1-cup (96-gram) serving of raw, whole white button mushrooms contributes only 3 grams of carbs to your daily intake. Similarly, a cup of raw oyster and shiitake mushrooms contains around 6 and 7 grams of carbs, respectively. Portobello mushrooms contain approximately 3 grams of carbs per cup, making them a great option for meatless burgers.
These mushroom varieties offer not only low carb content but also a rich umami flavour that enhances the taste of both vegetarian and meat-based dishes. They are incredibly versatile and can be enjoyed raw or cooked in various dishes such as stir-fries, casseroles, scrambles, and soups. For instance, shiitake mushrooms shine in Asian dishes and soups with their rich, earthy taste. Portobellos, known for their large size and meaty texture, make excellent substitutes for burgers when grilled or roasted. Oyster mushrooms are versatile and can enhance a variety of dishes, from pastas to risottos.
However, it is important to note that while mushrooms are low in carbs, they are high in fibre, which can be challenging to obtain on the keto diet as it is typically found in carb-rich foods. Additionally, when incorporating mushrooms into your keto meals, be mindful of any other ingredients or cooking methods that may add carbohydrates.

For example, a 1-cup (96-gram) serving of raw, whole white button mushrooms contributes 3 grams of carbs to your day.
It is worth noting that the carb content of mushrooms can vary depending on the variety and cooking method. For instance, 1 cup of raw button mushrooms has 1 gramme of net carbs, while 0.5 cups of cooked shiitake mushrooms have 8.2 grams of net carbs.

Canned mushroom products may not be keto-friendly
Mushrooms are generally keto-friendly as they are low in carbohydrates and calories. Common types of mushrooms, such as white button, shiitake, oyster, and portobello, are keto-friendly in their natural form. However, canned mushroom products may not be keto-friendly.
When following a keto diet, it is important to monitor your carbohydrate intake closely. The keto diet is designed to be very low in carbohydrates and high in fat, with moderate amounts of protein. By reducing carbohydrate intake, the body is encouraged to enter a state of ketosis, where it uses ketone bodies instead of glucose as its primary source of energy.
While mushrooms are naturally low in carbohydrates, the way they are prepared and served can affect their keto-friendliness. Canned mushroom products, such as cream of mushroom soup, often contain added ingredients that increase the carbohydrate content. For example, a 1/2-cup (120-mL) serving of Campbell's Cream of Mushroom prepared soup contains 8 grams of carbohydrates, and there are 2.5 servings per can, resulting in a total of 20 grams of carbohydrates.
It is important to read the nutrition labels on canned mushroom products to determine their carbohydrate content and make an informed decision about their inclusion in a keto diet. The keto diet can be restrictive, and it is always recommended to consult with a doctor or registered dietitian before starting any new diet.
In conclusion, while mushrooms are typically considered keto-friendly, canned mushroom products may have higher carbohydrate levels and may not align with the strict carbohydrate limits of a keto diet.

Mushrooms are a versatile ingredient in keto recipes
Mushrooms are a keto-friendly food, as they are naturally low in carbohydrates. This makes them a versatile ingredient in keto recipes.
A cup of raw white button mushrooms contains only 3 grams of carbohydrates, while a cup of raw oyster and shiitake mushrooms contains around 6 and 7 grams of carbohydrates, respectively.

Mushrooms can also be used as a substitute for bread in recipes like pizzas or burgers. For example, a lettuce-wrapped blended burger with mushrooms chopped and seamlessly blended into the meat patty creates a unique umami mouthfeel while keeping the dish keto-friendly.
Additionally, mushrooms can be shaved into "zoodles" to mimic the texture of traditional pasta, providing a nutritious and filling meal. They can also be added to soups, such as a chicken soup with diced carrots, onion, celery, and baby bella mushrooms, providing a flavorful and satisfying keto-friendly option.
When incorporating mushrooms into keto recipes, it is important to be mindful of the overall carbohydrate content of the dish. While mushrooms are low in carbs, consuming large quantities or combining them with other carb-heavy ingredients may impact ketosis. Therefore, it is recommended to check the nutrition labels, especially when using canned or packaged mushroom products, as these may have higher carbohydrate content.
