How serving-size math works on this page: USDA stores all nutrient amounts on a per-100g basis for consistency across the catalog. Because the manufacturer declared a 52g serving for this product, the headline values (calories, macros) are multiplied by 52/100 = 0.520 to render the same values you would read on the FDA Nutrition Facts panel. The page surfaces both bases for full transparency.
