Source and method
Nutrient values are from USDA FoodData Central, SR Legacy (April 2018 release, public domain), record 174276: "Soy protein isolate". Values are stored per 100 g exactly as USDA reports them and scaled to each serving by weight. The Nutrition Facts panel applies the FDA rounding rules in 21 CFR 101.9; tables and text show the scaled amounts at reading precision, so a figure can differ slightly from the panel. A nutrient USDA does not report for this food is shown as not reported, never as a guessed value.
SR Legacy predates the added sugars field. This is a whole or unsweetened food, so added sugars are shown as 0 g. View the USDA record ↗
