冰爽的饮料是夏日"解暑利器"之一，随着消费者"控糖"意识的不断提升，用甜味剂代替糖的无糖、低糖 饮料越来越受到消费者青睐，但对于甜味剂安全性的质疑也层出不穷。"无糖饮料真的不含糖吗？""震 惊！代糖导致糖尿病实锤了！""甜味剂不仅不能减肥，还会让你更胖！"……很多人都在社交媒体看过 这种"爆款"标题，以上说法是真是假？甜味剂还能吃吗？ 中国工程院院士陈君石介绍，甜味剂已经被全球上百个国家安全使用了近百年。在此过程中，甜味剂不 断接受各个国际食品安全机构的挑战，最终的科学评估结论均是：只要合规使用，就是安全的。 关于甜味剂的三大灵魂拷问 问题一：无糖饮料真的不含糖吗？ "无糖"≠"无蔗糖"，前者真的不含糖，后者可未必。 科信食品与健康信息交流中心副主任阮光锋表示，我国规定，饮料产品中糖含量小于等于0.5g/100ml时 即可称为无糖饮料。常见的无糖饮料一般用甜味剂代替糖提供甜味，只要商家没有违规添加糖，那就可 认定为不含糖。但有些打着"无蔗糖"口号的产品只代表不含蔗糖，可能含有其他种类的糖（果糖或果葡 糖浆等），两者概念不同，不要混淆。 而"无糖饼干"和"无糖面包"这类淀粉制品，即便没有添加蔗糖，其碳水化合物含 ...

Core Viewpoint - The recent release of the "Standardization Development Plan for the Elderly Industry (2025-2030)" by the China Aging Industry Association highlights the importance of standardization in elderly products, but raises concerns about the practical usability of these products for the elderly [1][2]. Group 1: Importance of Standardization - Standardization is crucial to ensure safety in elderly products, as the absence of unified safety standards can lead to dangerous situations, such as with electric wheelchairs [1]. - There is a risk that some companies may misuse standardization as a marketing tool, labeling ordinary household appliances as "elderly-specific" without meaningful modifications [1][2]. Group 2: Effective Standards - True elderly standards should be based on scientific considerations of physiological functions and detailed observations of living scenarios, as exemplified by Japan's requirement for a minimum color contrast of 30% between floors and walls in nursing homes [2]. - Standards should not only focus on technical parameters but also consider the practical usability for the elderly, such as the complexity of elevator buttons that may deter elderly users from using them independently [2]. Group 3: User Experience and Feedback - The essence of the silver economy is rooted in familial care, which cannot be standardized; thus, establishing a system for "elderly experience officers" could enhance service quality [3]. - Real-life feedback from elderly users is essential for improving standards, as demonstrated by a nursing home in Hangzhou that allows residents to rate caregivers [3]. Group 4: Market Demand and Product Development - The silver economy requires a deeper understanding of elderly needs, suggesting that product development should focus on user-friendly designs rather than merely meeting compliance standards [3]. - The industry should prioritize practical usability over mere adherence to national standards, emphasizing the importance of ensuring that products are genuinely usable by the elderly [3].
