According to a recent review published in Journal of Pharmaceutical Analysis, anthocyanins - a plant compound responsible for the vibrant colors in fruits and flowers - may counteract some of the harmful reproductive impacts of micro- and nanoplastic (MNP) exposure.
In short:
- Anthocyanins are widely found in fruits, vegetables, beans and nuts, and have antioxidant and anti-inflammatory properties.
- Anthocyanins may help protect sperm quality and preserve ovarian function by reducing oxidative stress and tissue damage, both of which have been linked to MNP exposure.
- Studies also suggest that anthocyanins may help improve the function of some hormone receptors, restoring hormonal balance.
Key quote:
“The accumulation of [MNPs] contaminants across ecosystems raises significant concerns for human health due to their potential dispersion within the human body through respiratory, integumentary, and digestive systems.”
Why this matters:
Plastic use has continued to grow exponentially since the mid-twentieth century, with nearly a metric ton of plastic waste produced for every person on the planet. Recent studies have confirmed that microplastics are present in all parts of the human body that have been examined, highlighting an urgent need for solutions that address their potential harm to public health. While it’s important to further research ways that individuals can take action to address their own exposure, regulatory limits on plastic production are needed to stop the creation of MNPs at the source.
