Well Adjusted: Microplastics and Your Health

While traveling, I brewed my morning cup of coffee with a Keurig and started to wonder about the plastic pod I was using. We’ve all heard the warnings about microwaving food in plastic containers, but what about these Keurig cups?
Studies have shown that plastic can release microplastics when exposed to high heat. And yes, Keurig cups aren’t exempt from this. Sipping on tiny plastic particles with my coffee wasn’t exactly appetizing, and it got me thinking about how much microplastic we might unknowingly consume daily.
Living in Oregon, we’re conscious about the environment. Many of us recycle, use reusable bags, and try to reduce waste, but microplastics are a sneaky pollutant that’s much harder to avoid. Did you know that outdoor gear, like those cozy fleece jackets we all love, can significantly contribute? When washed, these fabrics shed tiny plastic fibers that end up in our waterways. Microplastics have made their way into oysters harvested along the Oregon coast. It’s disturbing to think that our beloved seafood is contaminated because of the clothes we wear.
Even more alarming, research suggests that the average person could be ingesting about five grams, equivalent to a credit card’s worth of microplastics each week! This statistic is mind-boggling, and it’s not just in food — plastics are in the air we breathe, the water we drink, and even in the salt we sprinkle on our food.
Microplastics are everywhere, and many everyday products contribute to our exposure. For example, plastic teabags, which release microplastics when steeped in hot water, are a hidden source. Chewing gum is another, as most “gum base” is made from synthetic plastics. Even the dust in our homes contains microplastics from synthetic carpets, furniture, and household items.
So what does all this mean for our health? Studies indicate that microplastics can cause inflammation, disrupt hormones, and potentially lead to long-term health issues. The long-term effects are still being studied, but the potential risks are enough to make anyone think twice about their plastic consumption.
While microplastics are pervasive, being mindful of our plastic use can help reduce our exposure. Ditching single-use plastics, especially plastic water bottles, is a big step. Opt for alternatives like stainless steel or glass bottles. Avoid heating food or drinks in plastic containers. Use loose-leaf tea instead of plastic teabags, and look for natural chewing gum without synthetic polymers. Investing in a good air purifier and vacuuming regularly with a HEPA filter can also help reduce the amount of microplastic dust in your home.
On a brighter note, Keurig has recognized the issue and is developing a new machine that uses plastic-free pods called K-Rounds. This is a clear example of how research and conscientious consumers can help spark positive changes. Hopefully, we will see more companies follow suit!
