Group 1: Consumer Awareness - Consumers are increasingly finding that the calorie counts on snack packaging are based on "serving" sizes, which can be significantly smaller than the total package weight, resulting in higher caloric intake than anticipated [1][4]. - The discrepancy in serving sizes can lead to confusion, as some products may label servings in fractions or specific weights that do not align with consumer expectations [4][9]. Group 2: Regulatory Standards - The labeling of nutritional information per "serving" is compliant with national regulations, as outlined in the GB28050-2011 and GB28050-2025 standards, which allow for both "per 100g" and "per serving" formats [19][20]. - The standards specify that serving sizes can vary based on the type of food, and manufacturers are encouraged to use reference values for serving sizes [20][24]. Group 3: Industry Practices - Many snack brands, such as Orion and Lay's, have adopted the "per serving" labeling to standardize nutritional information across various product sizes, which can create a perception of lower calorie content [24][25]. - The choice of serving size often aims to simplify consumer understanding and calculation of caloric intake, although it may also contribute to misleading perceptions of healthiness [24][25].
