A new study published in The FASEB Journal reports that moderate aerobic exercise may reduce several harmful effects of nanoplastic exposure in zebrafish, including oxidative stress, hormone disruption, and anxiety-like behavior. Researchers exposed adult female zebrafish to polystyrene nanoplastics for 21 days; some fish performed 20 minutes of moderate exercise daily while others remained sedentary, according to the study. Exercised fish showed reduced nanoplastic accumulation in ovarian tissue, improved antioxidant defenses, and normalized behavioral responses, the authors said.
Microplastics and nanoplastics have become pervasive in the modern environment. Common household plastics like bottles, teabags, and cutting boards shed these particles into food and drinks, according to a Swiss study cited by Cassie B. of NaturalNews.com [1]. A Columbia University-led study found that an average liter of bottled water contains nearly 240,000 plastic particles, with 90% being nanoplastics that can infiltrate cells and organs [2]. People are now consuming a credit card’s worth of plastic particles every week through tainted food and water, according to NaturalNews.com [3].
