January Focus: Microplastics and Your Health

Microplastics - tiny plastic fragments less than 5 millimeters - are everywhere: in the water we drink, the food we eat, the clothes we wear and even the air we breathe. Research on their health impact is still emerging, but findings are concerning. Microplastics have been detected in human organs and tissues, including the brain, heart and placenta, as well as in urine, breastmilk and newborn stool.

Studies suggest these particles may trigger inflammation, immune system impairment, tissue damage and abnormal organ development. A recent review linked microplastic exposure to reproductive, digestive and respiratory issues, and possibly colon and lung cancer. One study found patients with microplastics in arterial plaque faced higher risks of heart attack, stroke and death. Microplastics can also carry toxic chemicals and endocrine disruptors, amplifying potential harm. While we can’t completely avoid plastics, reducing exposure matters.

Ways to Reduce Microplastics

• Ditch Single-Use: Avoid plastic bags, bottles, straws and coffee cups.
• Switch Containers: Use glass, stainless steel or ceramic for food storage and heating.
• Filter Water: Install a tap or pitcher filter.
• Cook Smart: Don’t microwave in plastic; choose glass or ceramic.
• Wear Natural Fibers: Opt for cotton, wool or linen over synthetics.
• Check Labels: Avoid products with microbeads or excess plastic packaging.
