Article summary

A study by the University of Southern California found a link between exposure to 'forever chemicals' (PFAS) and liver cancer risk. The study analyzed blood samples from over 200,000 people and found that those with high levels of certain PFAS chemicals were more likely to develop liver cancer. The chemicals, commonly used in nonstick cookware and makeup, have been linked to various health problems. The study suggests that PFAS may interfere with normal liver function, leading to a buildup of fat and potentially nonalcoholic fatty liver disease.

Main themes

  • PFAS and health risks
  • nonstick cookware safety
  • alternative cookware materials
  • cookware maintenance and hygiene
  • temperature control and cooking oil safety
  • regulations and manufacturer responsibility
  • personal preferences and experiences

What commenters say

  • Some commenters argue that modern nonstick cookware is safe due to new regulations, while others claim that similar analogues have replaced the banned chemicals, potentially posing similar health risks.
  • The use of alternative cookware materials, such as stainless steel, carbon steel, and cast iron, is recommended by some as a safer option.
  • Others disagree, stating that well-seasoned cast iron or carbon steel pans can be just as nonstick as traditional nonstick pans, and that proper heat control and maintenance can mitigate any health concerns.
  • There is also discussion about the hygiene and maintenance of different cookware materials, with some arguing that cast iron is no less hygienic than other pans, while others recommend using specific cleaning products to maintain stainless steel cookware.
  • Some commenters share their personal experiences and preferences for different cookware materials, including ceramic and copper options.
  • The potential health risks of overheating certain cooking oils and the importance of proper temperature control are also mentioned.
  • The effectiveness of various cleaning methods and products, such as Bar Keepers Friend, is discussed in the context of maintaining cookware.
  • The idea that manufacturers should prioritize finding safer alternatives to PFAS rather than replacing them with similar chemicals is also raised.
