White mushrooms are not a good source of protein
White mushrooms are a type of edible fungus commonly used in cooking due to their mild flavor and versatility. They are low in calories and packed with various nutrients, including vitamins, minerals, and antioxidants. However, when it comes to protein content, they fall short.
According to one source, white mushrooms contain approximately 3.1 grams of protein per 100 grams. While this may seem like a decent amount, it is important to consider the caloric context. White mushrooms have a high protein-to-calorie ratio, but a low protein-to-volume or protein-to-weight ratio. This means that to obtain a substantial amount of protein from white mushrooms, one would need to consume a large quantity, which may not be practical or appealing.
Additionally, when compared to meat products, white mushrooms fall even shorter in terms of protein content. For example, duck, the meat with the lowest protein content among popular meat options, still has six times more protein per 100 grams than the most protein-rich mushrooms. Therefore, while white mushrooms can contribute some protein to one's diet, they should not be relied upon as a primary source, especially for those seeking meat alternatives.
In summary, while white mushrooms offer various nutritional benefits, they are not a good source of protein. To meet protein requirements, it is advisable to incorporate other plant-based sources or meat alternatives that offer higher protein content per volume or weight.

White mushrooms, specifically, are fat-free and packed with nutrients. They contain a variety of B vitamins, including riboflavin, niacin, selenium, copper, and pantothenic acid, which help provide energy by breaking down proteins, fats, and carbohydrates, and support the nervous system.

Compared to brown mushrooms, white mushrooms contain slightly more sodium, making them a healthy and delicious choice to pair with meats without the need for additional salt. They also contain more iron, providing 10% of the Daily Value per 5 medium caps, which is important for the body's growth and development.
While white mushrooms are not a substantial source of protein, they do offer other health benefits due to their nutrient density. They are low in calories and provide a variety of micronutrients, including minerals and vitamins. For example, eating 100 grams of crimini mushrooms, a type of white mushroom, per day has been found to reduce the likelihood of developing high blood pressure during pregnancy.
Overall, white mushrooms are a healthy and versatile ingredient that can enhance the nutritional value of a variety of dishes, despite not being a substantial source of protein.
