Core Viewpoint - The popularity of "internet celebrity salts" with exotic appeal is rising on e-commerce platforms, despite their prices being dozens to hundreds of times higher than regular salt, leading to concerns about consumer awareness and potential exploitation through misleading marketing [1][2]. Group 1: Market Trends - Various "internet celebrity salts" are marketed as "natural," "specific origin," and "rich in special minerals," claiming benefits such as calcium and zinc supplementation, which drives up their prices significantly [1][3]. - A 200g bottle of Himalayan pink salt is priced at 58 yuan, while a 454g package of French gray salt costs 108 yuan, indicating a price increase of approximately 50 times compared to regular salt [1]. Group 2: Consumer Awareness - Experts urge consumers to develop a correct consumption mindset and to be cautious of the extravagant claims surrounding "internet celebrity salts," which may lead to unnecessary spending [1][7]. - The term "natural" used in marketing is deemed to have little significance in the current food landscape, as all edible salts are derived from natural sources [5]. Group 3: Nutritional Claims - Claims that "eating salt can supplement calcium" are scientifically unfounded, as excessive salt intake can actually lead to calcium loss in the body [6]. - A recent study by the Chongqing Consumer Association tested 27 salt samples and found negligible amounts of trace minerals, suggesting that the mineral content in these salts is minimal and not a reliable source for supplementation [6][7]. Group 4: Regulatory Insights - Regulatory bodies are encouraged to enforce stricter guidelines against misleading advertising and to promote consumer education regarding the actual benefits of "internet celebrity salts" compared to regular salt [7].
