Plastic pollution is a growing concern as the wear and tear of plastic products release small particles that can have harmful effects on human health. To address this issue, researchers have developed biodegradable plastics made from plant starch instead of petroleum.
A recent study published in the Journal of Agricultural and Food Chemistry revealed that animals consuming particles from this alternative material experienced health problems such as liver damage and gut microbiome imbalances. Lead researcher Yongfeng Deng cautioned that biodegradable starch-based plastics may not be as safe as originally assumed.
Microplastics, which are plastic pieces less than 5 millimeters wide, are finding their way into human bodies through contaminated water supplies, foods, and even IV infusions. These particles have been linked to various health risks, including inflammatory bowel disease. Biodegradable plastics, particularly those made from starch, have been promoted as a safer and more environmentally friendly alternative to traditional plastics.
In the study, researchers compared three groups of mice: one group consuming normal chow and two groups consuming food infused with starch-based microplastics. The results showed that mice exposed to the starch-based plastic particles exhibited damaged organs, altered glucose management, and disrupted gut microbiota diversity. Deng emphasized that prolonged exposure to these microplastics could lead to a range of health impacts, including circadian rhythm disturbances and metabolic disorders.
While this study sheds light on the potential health risks associated with consuming starch-based microplastics, further research is needed to fully understand how these biodegradable particles break down in the body. It is crucial to continue investigating the effects of plastic pollution on human health and to develop sustainable solutions to mitigate these risks.
