Button Mushroom Nutrition Benefits and Facts

Nutritional summary

Button mushrooms are naturally low in energy, sodium, and fats, and contain no cholesterol or gluten .
These mushrooms are a unique source of ergothioneine (a sulfur-containing amino acid with antioxidant properties) and beta-glucan (a polysaccharide that supports immune function), both of which are bioactive compounds not typically found in high amounts in plants or animals .
Button mushrooms can become a significant source of vitamin D2 if they are exposed to UV light during growth or after harvest, as they contain ergosterol which converts to vitamin D when irradiated .
Systematic reviews of observational studies have linked higher mushroom consumption to a lower risk of total cancer and lower all-cause mortality, though these findings are based on long-term dietary patterns rather than short-term intervention .

Interesting fact

Button mushrooms, cremini, and portobellos are actually the same species (Agaricus bisporus) at different stages of maturity, with the white button being the youngest variety.
