Core Insights - The article highlights potential health risks associated with using certain types of thermos cups, particularly those made from non-food grade stainless steel materials [1][6]. Material Safety - Thermos cups are primarily made from stainless steel, with common grades being 201, 304, and 316 [4]. - 201 stainless steel is not food-grade and is mainly used for industrial purposes, posing health risks due to high manganese content which can leach into beverages [7]. - 304 and 316 stainless steels are recommended as they meet safety standards, with 304 being recognized as food-grade and having low manganese content [9]. Beverage Recommendations - Certain beverages should not be stored in thermos cups due to health concerns: - Tea: Long-term high-temperature storage can degrade nutrients and alter flavor [11]. - Milk: Prolonged warmth can promote microbial growth, leading to spoilage and potential food poisoning [12]. - Soy Milk: Similar to milk, it can spoil when kept warm for extended periods [13]. - Carbonated Drinks: Acidic beverages can corrode stainless steel, especially in substandard cups, leading to metal leaching [14]. - Juice: Acidic nature can also cause metal leaching, and residual sugars can promote bacterial growth [15]. - Traditional Chinese Medicine: Acidic components in herbal decoctions can react with metal, affecting efficacy [16].
