Ceramic cookware, on the other hand, does not typically contain PTFE, as it relies on a naturally nonstick ceramic surface. This makes ceramic cookware a safer option for those concerned with the potential hazards of PTFE.

However, even ceramic cookware can contain harmful chemicals, such as perfluorooctanoic acid (PFOA) and per- and polyfluoroalkyl substances (PFAS). These are both known as “forever chemicals” due to their persistence in the environment and resistance to breaking down. PFOA has been linked to health problems, including cancer and birth defects. PFAS are associated with liver damage and other health issues. While some ceramic cookware brands are marketed as PFOA and PFAS-free, it is essential to verify these claims before purchasing.

Lead and cadmium are two heavy metals that can also be found in ceramic cookware. One study investigated the lead exposure from lead-glazed ceramic cooking ware (LGC). The study aimed to determine if this cookware contained lead and the amount that might leach into food. The results showed that 52% of the tested ceramic vessels exceeded the FDA’s acceptable levels for lead in ceramic ware. When low-pH foods like tomatoes were cooked in these vessels, the lead intake was found to exceed the provisional tolerable total intake level for lead. The study concludes that LGC is still in use and poses a significant public health concern, indicating ongoing risk of lead exposure despite efforts to reduce such risks in the environment.

Lead and Cadmium can leach into food during the cooking process, posing serious health risks. Lead exposure can cause neurological disorders, while cadmium has been linked to kidney damage and bone loss. Some studies have shown that cooking in lead-glazed ceramic vessels can pose significant risks to human health. Therefore, it is crucial to choose ceramic cookware that is certified lead and cadmium-free.

In conclusion, while ceramic cookware may offer advantages over traditional nonstick cookware, it is not entirely free from potential toxicity concerns.
