Mushrooms have a lot to offer, from flavor to variety to nutrition. White mushrooms are actually the most cultivated type of mushroom worldwide.  So, are mushrooms keto-friendly?
What are Mushrooms?
Mushrooms aren’t a vegetable, rather, they belong to the fungi kingdom. White mushrooms (Agaricus bisporus) make up around 90% of the mushrooms consumed in the United States .
Low in calories, mushrooms offer a range of health-promoting effects, such as improved heart health. Some mushrooms have even been used medicinally for thousands of years.
Mushrooms can be harvested at different stages of maturity. When they’re young and immature, they’re known as white mushrooms if they have a white color. If they have a slight brown shade, they’re called crimini mushrooms. When fully grown, they become portobello mushrooms, which are darker and larger.
White mushrooms grow on composted soil with a range of other bacteria and fungi [3,4]. You can enjoy dried and fresh mushrooms raw or cooked and you can even rehydrate dried mushrooms by soaking them in water.
You can find mushrooms in frozen, fresh, dried, canned, or even powdered form. Fresh mushrooms only have a short shelf life of 3-4 days. To extend shelf life without compromising nutritional quality, you could try freezing, canning, or drying them .
Mushrooms are nutrient-dense and provide vitamin D, selenium, phosphorous, and folate. They’re also rich in glutathione — an antioxidant that helps eliminate potentially harmful substances from the body [6,7,8].
Are Mushrooms Keto Friendly?
One cup (96 grams) of whole white mushrooms offers: 
- 21 calories
- 3 grams of carbs
- 1 gram of fiber
- 3 grams of protein
- 0 grams of fat
With such a low carb count, mushrooms are definitely a keto friendly choice. They’re also a great way to add more nutrition to your ketogenic diet! The carb count of mushrooms varies slightly depending on the type and if it’s raw or cooked .
