Mushrooms are a nutritious food with a unique nutritional profile. They are low in calories and contain a range of vitamins and minerals, including B vitamins, copper, potassium, and selenium. Mushrooms also contain antioxidants, which can provide various health benefits. When it comes to carbohydrates, the amount varies depending on the type of mushroom. Common varieties like white button, shiitake, oyster, and portobello are naturally low in carbohydrates, with a one-cup serving contributing around 2 to 7 grams of carbs. Canned or packaged mushroom products, however, tend to be higher in carbs due to added ingredients. Overall, mushrooms are considered a keto-friendly food and can be enjoyed as a nutritious and low-carb option.

| Carbohydrates in mushrooms | Carbohydrates are one of the three primary macronutrients, along with fat and protein. Mushrooms contain an indigestible carbohydrate called chitin. Common types of mushrooms like white button, shiitake, oyster, and portobello are low in carbohydrates and keto-friendly in their natural form. A 1-cup (96-gram) serving of raw, whole white button mushrooms contains around 3 grams of carbs. A cup of raw oyster and shiitake mushrooms contains around 6 and 7 grams of carbs, respectively. |
| Carbohydrates and the keto diet | A ketogenic diet requires a severe restriction of carb-rich foods. Mushrooms are considered keto-friendly due to their low carbohydrate content. |
| Carbohydrates and health | Carbohydrates provide energy. Mushrooms have a naturally low glycemic index, which means they are presumed to have little negative effect on blood glucose or insulin response due to their low carbohydrate content. Whole carbs, found in mushrooms, are not processed and are more in their natural form. Eating real, unprocessed food is important for health. |

What You'll Learn
Carbohydrates, fat and protein are the three primary macronutrients
Carbohydrates, fat, and protein are the three primary macronutrients. Carbohydrates, or carbs, are the body's main source of energy. They are classified into three main dietary categories: fiber, starches, and sugars. While fiber does not directly provide energy, it feeds the good bacteria in the digestive system. Starches and sugars, on the other hand, are broken down into glucose, which serves as fuel for the body. Additionally, excess glucose can be converted into fat and stored for later use.
Mushrooms, which are technically classified as fungi, contain carbohydrates in the form of fiber. Common types of mushrooms like white button, shiitake, oyster, and portobello are naturally low in carbohydrates, with a 1-cup serving contributing around 2.3 to 3 grams of carbs. This makes them suitable for low-carb diets like keto. Mushrooms are also low in calories and virtually fat-free, making them a heart-healthy food choice.
In addition to their low carb content, mushrooms offer various nutritional benefits. They are a good source of B vitamins, including riboflavin, niacin, and pantothenic acid (vitamin B5). These vitamins assist in energy release from carbohydrates and other macronutrients. Mushrooms also contain minerals such as copper, potassium, phosphorus, iron, and selenium. These minerals play crucial roles in the body, including energy production, nerve and muscle function, and maintaining fluid and electrolyte balance.
Furthermore, mushrooms are rich in antioxidant compounds such as ergothioneine and glutathione, which are not commonly found in many plant foods. These antioxidants help protect cells from oxidative damage and may contribute to slowing down cognitive decline associated with aging. Certain varieties of mushrooms, like porcini and white button mushrooms, are particularly high in these antioxidants. Mushrooms also contain non-nutritive substances like polysaccharides, indoles, polyphenols, and carotenoids, which have been linked to potential antioxidant, anti-inflammatory, and anticancer effects.

Carbohydrates provide energy
Carbohydrates are one of the three primary macronutrients, along with fat and protein. They provide the body with energy. Most carbs get broken down or transformed into glucose, which can be used as energy. They can also be turned into fat (stored energy) for later use.
Mushrooms are a good source of carbohydrates and can be consumed as part of a keto diet. They are low in carbohydrates and calories and contain modest amounts of fibre and various nutrients. A cup of raw mushrooms contains just 15 calories, making this a low-calorie food. Mushrooms are also a good source of copper, potassium, iron, and B vitamins. They also contain an indigestible carbohydrate called chitin, which contributes "bulk" to our diet. Chitin is also found in shrimp and crab shells but not in plants.
White button mushrooms are the most common type of mushroom and are naturally low in carbohydrates. One cup of whole white button mushrooms, weighing 96 grams, contains 3.1 grams of carbohydrates. Similarly, Portobello mushrooms, which are the largest cultivated mushrooms, contain around 3 grams of carbohydrates in a 1-cup (86-gram) serving.
Oyster mushrooms are also low in carbohydrates and contain around 6 grams of carbs per cup. Shiitake mushrooms are another variety that is low in carbs, with a single piece weighing 19 grams and containing 1.3 grams of total carbs.
In summary, mushrooms are a good source of carbohydrates, which provide the body with energy. They are low in calories and carbohydrates and contain various essential nutrients, making them a healthy and nutritious food choice.

Carbohydrates can be categorised as whole or refined
Mushrooms are low in carbohydrates and keto-friendly in their natural form. A cup of raw white button mushrooms weighing 96 grams contains around 3 grams of carbohydrates. Similarly, a cup of raw oyster and shiitake mushrooms contains around 6 and 7 grams of carbohydrates, respectively. However, canned or packaged mushroom products, such as cream of mushroom soup, tend to be higher in carbohydrates due to processing.
Carbohydrates are one of the three primary macronutrients, along with fat and protein. They can be categorised as whole or refined, which refers to the level of processing and the presence of natural fibre in the food. Whole carbohydrates, also known as complex or "good" carbohydrates, are minimally processed and retain the natural fibre found in the food. They are typically loaded with nutrients and fibre and are associated with improved metabolic health and a lower risk of disease. Examples of whole carbohydrates include vegetables, whole fruits, whole grains, legumes, potatoes, and mushrooms.
On the other hand, refined carbohydrates, also known as simple or "bad" carbohydrates, have undergone more processing and have had their natural fibre removed or altered. They tend to cause spikes in blood sugar levels, which can lead to subsequent crashes, triggering hunger and food cravings. Refined carbohydrates are often lacking in essential nutrients and are linked to health issues such as obesity, type 2 diabetes, and metabolic diseases. Examples of refined carbohydrates include white pasta, white bread, white rice, sugar-sweetened fruit juices, pastries, cookies, cakes, and breakfast cereals.
It is recommended that 45 to 65 percent of daily calories come from carbohydrates, with a focus on choosing complex, unrefined carbs over refined carbs. Whole, unprocessed foods are important for health, and populations consuming a significant portion of their calories from these whole carbohydrates have exhibited positive health outcomes. Therefore, when including carbohydrates in the diet, it is crucial to prioritise whole, complex carbohydrates that are rich in fibre and nutrients to promote overall health and manage blood sugar levels effectively.
