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, “Parsnips, raw” (FDC 170417). 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.
