Around 3.7 g net carbs per 100 g — fits a keto day comfortably.
For keto, the key number is net carbs per 100 g: if it's under ~5 g, you're fine; over ~10 g, portions matter; over 20 g, skip it.
3.70 g / 100 g
22 kcal / 100 g
Protein: 2.50 g
Fat: 0.10 g
Target carbs: 5–10% of calories, cap ~30 g/day.
A 100 g portion of mushrooms, brown, italian, or crimini, raw costs you 3.70 g of net carbs. On a typical Keto day with a 30 g carb ceiling, that's 12% of your daily budget.
Pair it with fat and protein to slow glucose response — that's generally good practice regardless of regime.
