About Portobello mushrooms
Portobello mushrooms are a mature form of the Agaricus bisporus species, native to Europe and North America. These large, flat mushrooms are commonly used in Italian, Mediterranean, and American cuisines as a plant-based alternative to meat due to their hearty texture and umami flavor. They are low in calories, providing about 20-25 calories per 100 grams, while being a good source of fiber, B vitamins (notably niacin and riboflavin), selenium, and copper. Portobello mushrooms also contain antioxidants like ergothioneine and polyphenols, which contribute to their nutritional profile.
Health Benefits
- Supports energy metabolism with high levels of niacin (15% DV per 100 g) and riboflavin (16% DV per 100 g), essential for converting food into energy.
- Boosts immune function due to selenium (18% DV per 100 g), a mineral important for antioxidant defense and immune support.
- Promotes gut health as they provide dietary fiber (1 g per 100 g), which aids in digestion and supports healthy gut bacteria.
Dietary Considerations
