Mushroom has a low glycemic index of 10 (typical range 5 to 18). A serving of 1 medium (18 g) has a glycemic load of 0, which is low. Per 100 g it provides 22 calories, 3.1 g protein, 3.3 g carbohydrate (1 g fiber, 2 g sugars) and 0.3 g fat.

Serving used for glycemic load: 1 medium (18 g).

Mushroom has a glycemic index of 10, which is low (low is 55 or under, high is 70 or over). The glycemic load of a 1 medium (18 g) serving is 0, which is low.
Glycemic load is the better guide, because it accounts for portion size. A serving of mushroom has a glycemic load of 0 (low). Eating it with protein, fat or fiber slows absorption further. This is general information, not medical advice; people with diabetes should follow their clinician's guidance.
Mushroom has 22 calories per 100 g, and about 4 calories in a 1 medium (18 g) serving.

Open the free web appGlycemic index: NutriOptio's reference table, compiled from the University of Sydney GI database and the international tables of glycemic index and glycemic load; the range reflects variation across studies, ripeness and preparation. Nutrition: USDA FoodData Central, SR Legacy, “Mushrooms, white, raw” (FDC 169251). Glycemic load = GI × available carbohydrate (carbohydrate minus fiber) per serving ÷ 100. Nutri-Score computed with the 2017 general-food algorithm. NOVA group 1 follows from the NOVA definition: a whole food, only cleaned, dried or cooked.
