Health benefits of white mushrooms
White button mushrooms, scientifically known as agaricus bisporus, are one of the few plant foods that contain a natural source of vitamin D. This vitamin is essential for maintaining strong bones and a healthy immune system, as well as regulating mood, cognitive function, and gut health. When exposed to sunlight or ultraviolet light during cultivation, white mushrooms can produce even more vitamin D.
White mushrooms are also a good source of protein, which is crucial for the creation of new cells, wound healing, regulating the endocrine system, and promoting growth and development in children, teens, and pregnant people. They contain anti-inflammatory and antioxidant compounds, including flavonoids, which can improve cell survival and encourage natural cell death to prevent tumour growth. The antioxidant properties of white mushrooms help fight oxidation, preventing or delaying cell damage.
Additionally, white mushrooms are rich in B-complex vitamins, including riboflavin, niacin, and pantothenic acid, which aid in energy production by breaking down fats, proteins, and carbohydrates. They are also a good source of potassium, which helps control blood pressure. White mushrooms can be used as a meat substitute due to their meaty texture and protein content, making them a healthy addition to vegetarian dishes.
According to research, white button mushrooms can enhance the activity of critical cells in the immune system, specifically dendritic cells, which play a vital role in recognising and neutralising antigens on invading microbes. This suggests that consuming white mushrooms may help strengthen the body's defences against disease-causing pathogens.

Ways to cook white mushrooms
White sliced mushrooms are versatile and easy to cook. Here are some ways to prepare them:
Sautéing
Sautéing is a popular way to cook mushrooms. To do this, heat olive oil and butter in a wide skillet over medium heat. Add the mushrooms in a single layer and leave them to cook for 3-5 minutes. Stir them, then spread them back into a layer to cook on the other side. Season with salt and pepper, and add garlic, lemon, thyme, and butter, if desired. You can also add wine, teriyaki sauce, and sliced garlic to enhance the flavor.
Pan-frying
To pan-fry mushrooms, heat a pan with oil on high heat. Chop the mushrooms and throw them into the pan, allowing them to sear and develop flavor. You can add butter, salt, and pepper for flavor. For extra flavor, add thyme, white wine, shallots, or garlic.
Stir-frying
To stir-fry mushrooms, wash and trim the stems, then cut the mushrooms into quarters. Season with Italian seasoning, garlic powder, salt, and pepper, and toss in olive oil. Heat a mixture of olive oil and butter in a pan to prevent scorching. Stir-fry the mushrooms, flipping them every minute or two until they are nicely browned.
Roasting
To roast mushrooms, preheat your oven to a suitable temperature. Clean the mushrooms and cut them into similar-sized pieces. Toss the mushrooms in olive oil and spread them out on a baking sheet. Roast them in the oven until they are golden brown and cooked to your desired level of doneness.
Mushrooms are versatile and can be served as a side dish, added to sauces, soups, rice, or used as a topping for meat or burgers.
