Tomato has a low glycemic index of 15 (typical range 10 to 22). A serving of 1 medium whole (2-3/5" dia) (123 g) has a glycemic load of 0, which is low. Per 100 g it provides 18 calories, 0.9 g protein, 3.9 g carbohydrate (1.2 g fiber, 2.6 g sugars) and 0.2 g fat.
Serving used for glycemic load: 1 medium whole (2-3/5" dia) (123 g).

Tomato has a glycemic index of 15, which is low (low is 55 or under, high is 70 or over). The glycemic load of a 1 medium whole (2-3/5" dia) (123 g) serving is 0, which is low.
Glycemic load is the better guide, because it accounts for portion size. A serving of tomato 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.
Tomato has 18 calories per 100 g, and about 22 calories in a 1 medium whole (2-3/5" dia) (123 g) serving.
Tomato is NOVA group 1: unprocessed or minimally processed.
Photograph your plate, scan a barcode or say what you ate. NutriOptio grades every food for glycemic load, Nutri-Score and processing, weighted to your goal.
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, “Tomatoes, red, ripe, raw, year round average” (FDC 170457). 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.
