预包装食品上的“NRV%”让人看不懂

Core Viewpoint - The article highlights the confusion among consumers regarding the Nutrient Reference Value percentage (NRV%) on food packaging, which lacks a unified calculation standard, leading to potential misinterpretation of nutritional content [1][2]. Group 1: Consumer Awareness - Many consumers are unaware of the meaning of NRV%, with some only having a vague understanding that it relates to nutrition [1][2]. - The lack of public knowledge about NRV% is attributed to the complexity of nutritional information and insufficient educational outreach [2]. Group 2: Calculation Standards - The calculation standards for NRV% vary significantly across different brands, creating a hidden trap for consumers [3]. - Most brands use different serving sizes for their nutritional information, which can mislead consumers about the actual intake of nutrients when consuming an entire package [3]. Group 3: New Standards Introduction - The National Health Commission has introduced a new standard for prepackaged food nutrition labeling, which includes the concept of "Serving Reference Values" [5]. - The new standard aims to ensure that the serving size is close to recommended reference values, allowing consumers to make more informed dietary choices [5].
