Nutrition: USDA FoodData Central, SR Legacy, “Soy protein isolate” (FDC 174276). 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.
