What You'll Learn

Carbohydrate content varies across different mushroom types
Mushrooms do contain carbohydrates, but they are not considered a starchy food. The amount of carbohydrates in mushrooms varies depending on the variety. For instance, a cup of raw oyster and shiitake mushrooms contains around 6 and 7 grams of carbohydrates, respectively, while white button mushrooms have a lower carb count of 3 grams per cup. White mushrooms have the lowest carb count by far, but this does not necessarily indicate a healthier option. Mushrooms' carbohydrates primarily exist as healthy dietary fibre, so those containing larger amounts may be more advantageous.
Oyster mushrooms have a single-piece carb content of 9.52 grams, with 3.6 grams of fibre. Portabella mushrooms have a single-piece carb content of 4.26 grams, with 1.3 grams of fibre. In contrast, a single piece of shiitake mushroom, weighing 19 grams, only has 1.3 grams of carbohydrates.
Mushrooms are a rich source of dietary fibre, a form of carbohydrate. They are non-sugary and non-starchy, meaning they do not negatively affect blood sugar or body weight like other high-carb foods. Instead, the carbohydrates in mushrooms may improve metabolic health and help maintain an optimal body weight. They are also low in calories and fat, making them a great addition to any healthy diet, even for those counting carbohydrates.
The weight of mushrooms can be misleading when considering their carbohydrate content. Fresh mushrooms are heavier, but as they dry out, they lose weight while retaining the same amount of carbohydrates. Therefore, it is recommended to use pre-packaged mushrooms with stated nutritional values when counting carbohydrates.
Mushrooms are among the most keto-friendly foods due to their low carbohydrate content and high fibre content. They are a good option for those following a ketogenic diet, which involves significantly reducing carbohydrate intake.

The amount of carbohydrates in mushrooms varies depending on the variety. For example, a cup of raw oyster and shiitake mushrooms contains around 6 and 7 grams of carbs, respectively. In contrast, white mushrooms have a lower carb count, with 26 grams of carbs per 100 grams of mushrooms.
Mushrooms are a rich source of dietary fibre, which can help to prevent constipation, a common side effect of the keto diet. They are also low in calories and fat, making them a keto-friendly food. Additionally, they contain several antioxidants, such as ergothioneine and glutathione, which can protect cells from oxidative damage.
Mushrooms are a good source of essential minerals and vitamins, including B vitamins and minerals like selenium, copper, and potassium. They can also provide a significant amount of our daily requirement of copper, niacin, pantothenic acid, selenium, and riboflavin.
Overall, mushrooms are a healthy and nutritious food that can be enjoyed both raw and cooked. They are a good option for people following a keto diet due to their low carbohydrate content and high fibre content.

Mushrooms are keto-friendly
A cup of raw oyster and shiitake mushrooms contains around 6 and 7 grams of carbs, respectively, while a cup of raw whole white button mushrooms contributes 3 grams of carbs. Mushrooms are also a good source of dietary fiber, which is a form of carbohydrate. The fiber in mushrooms can help to prevent constipation, a common side effect of the keto diet, and improve metabolic health.
In addition to being low in carbs, mushrooms are high in fiber, B vitamins, and minerals like selenium, copper, and potassium. They also contain several antioxidants, like ergothioneine and glutathione, which can help protect your cells from oxidative damage. Mushrooms can be enjoyed both raw and cooked and used in a variety of ways that are suitable for a keto diet, such as stir-fries, casseroles, scrambles, soups, or stuffed with low-carb ingredients like cream cheese and bacon.
However, it's important to note that the amount of carbohydrates in mushrooms can vary depending on their water weight. Fresh mushrooms are much heavier than those that have been sitting in the fridge for a while, as mushrooms usually hold a lot of water. When they dry out, they weigh less, but the carb content stays the same. Therefore, it is recommended to use pre-packaged mushrooms when in doubt, as their carb content is more consistent. Additionally, while canned mushroom products can be used, it is important to check the nutrition labels as these items may be higher in carbs and might not fit into your daily keto limit.

The carbohydrates in mushrooms exist primarily as fiber, which has been linked to improved metabolic health and maintaining optimal body weight. This is because mushrooms are low in fat and calories while being packed with essential vitamins and minerals. As a result, they are considered keto-friendly and can be enjoyed as part of a healthy diet, even for those counting carbs or following a keto diet.
The keto diet involves significantly reducing carbohydrate intake and has become popular for its potential benefits, including rapid weight loss, increased insulin sensitivity, and reduced blood pressure. However, it can also cause unpleasant side effects, such as nausea, headaches, fatigue, dizziness, and constipation. Mushrooms, being a non-starchy vegetable, are allowed on the keto diet and can be consumed in their natural form or cooked in keto-friendly dishes.
While mushrooms contain carbohydrates, they are considered "whole" carbs, found in unprocessed foods like vegetables, whole grains, and legumes. Unlike refined carbs, which are associated with obesity, whole carbs from fiber-rich, whole foods like mushrooms are not linked to weight gain. In fact, mushrooms are known to provide essential nutrients, including copper, niacin, pantothenic acid, selenium, and riboflavin.
In conclusion, the carbohydrates in mushrooms, particularly in the form of dietary fiber, may contribute to improved metabolic health. Mushrooms are a nutritious food that can be incorporated into various dishes, making them a healthy addition to one's diet, even when following a keto or low-carb eating plan.
