  • Certain common tableware materials can leach harmful substances, posing health risks.
  • Melamine is unsuitable for hot foods due to formaldehyde leaching, while Styrofoam releases styrene, a potential carcinogen.
  • Glass, stainless steel, and food-grade ceramics are recommended as safer alternatives.

Daily use of common tableware like bowls, boxes, and cups may pose hidden health risks as certain materials can leach toxic substances, according to Dr. Li Ssu-hsien. She highlights three high-risk categories and advises caution with everyday choices that could impact well-being.

Melamine is not suitable for hot foods; formaldehyde leaching can exceed safe limits by tens of times at high temperatures.

Melamine, often found in restaurant tableware, is made from formaldehyde resin and is not suitable for hot or acidic foods. Studies show that under high temperatures, formaldehyde leaching can exceed safe limits by tens of times. Similarly, Styrofoam, commonly used for takeout, releases styrene when exposed to heat, hot liquids, or oils. Styrene is classified as a "possible carcinogen."

Dr. Li categorizes common containers into red, yellow, and green light risks. Red light items to avoid include Styrofoam and melamine. Yellow light items, such as PET plastic bottles (like water bottles) and PP plastic takeout containers, require careful use. While PP is more heat-resistant, studies indicate it can still release microplastics when heated, posing a metabolic risk. PET bottles should not be reused, especially with hot liquids, due to the leaching of antimony and microplastics.

Styrofoam, when encountering hot food, hot soup, or oil, releases styrene, which is listed as a 'possible carcinogen.'

For safer choices, Dr. Li recommends green light options like stainless steel (especially 316 grade for better corrosion resistance), titanium, and glass. While ceramics are generally safe, she advises choosing those with food-grade certification, as brightly colored glazes on non-food-grade pottery may contain lead or cadmium. The doctor emphasizes that simple choices in daily tableware can significantly contribute to maintaining good health.

Glass and stainless steel are the easiest upgrade options to get started with.
