A new study has found that frequent consumption of food from plastic takeout containers may significantly increase the risk of congestive heart failure. Conducted by Chinese researchers, the peer-reviewed study highlights changes in the gut biome as a potential cause of heart-related complications.

The study examined over 3,000 individuals in China to assess the correlation between plastic container use and heart disease. In addition, researchers conducted experiments on rats, exposing them to plastic chemicals leached from takeout containers when filled with boiling water. The findings indicated that frequent exposure to these chemicals altered gut microbiota, leading to inflammation and oxidative stress, ultimately affecting heart muscle tissue.

Plastic containers can contain thousands of chemicals, including BPA, phthalates, and PFAS, which have been linked to various health concerns, including cancer and reproductive harm. While this study did not identify specific chemicals responsible for heart disease, it reinforced previous research on the link between gut health and cardiovascular issues.

The study also found that plastic chemicals leach at significantly higher rates when exposed to heat, with earlier research showing that up to 4.2 million microplastic particles per square centimeter can be released when plastic is microwaved.

Although the study did not provide direct recommendations, public health experts advise against microwaving or adding hot food to plastic containers. Alternatives such as glass, wood, or stainless steel utensils and storage are suggested to minimize exposure. For takeout, consumers may consider transferring food into glass containers upon reaching home.
