Are You Eating a Credit Card Every Week?
It sounds hard to believe, but you've probably heard the claim that the average person consumes about a credit card's worth of plastic every week. While researchers continue to debate the exact amount, one thing is clear: microplastics are everywhere. They've been found in our drinking water, seafood, table salt, packaged foods, and even the air we breathe. The "credit card" estimate came from a landmark report by the World Wildlife Fund (WWF) and the University of Newcastle, which helped bring global attention to this growing issue.
As a nurse, I'm passionate about helping people make simple lifestyle changes that can protect their health. Researchers have now identified microplastics in human blood, lungs, placentas, and even brain tissue. A recent Stanford Medicine review explains that while scientists are still learning exactly what these tiny particles mean for our long-term health, early evidence suggests they may contribute to inflammation, oxidative stress, hormone disruption, and immune system changes. That's enough for me to encourage taking practical steps to reduce our exposure whenever we can. 🌱
“An average person could be ingesting approximately 5 grams of plastic every week. ”
5 Simple Ways to Reduce Microplastics in Your Diet
1. Filter your drinking water – A quality water filter can help reduce microplastics in your drinking water. Choose reusable glass or stainless-steel bottles instead of single-use plastic whenever possible.
2. Eat more fresh, whole foods – Fresh fruits, vegetables, and minimally processed foods typically have less plastic exposure than heavily packaged convenience foods.
3. Don't microwave food in plastic – Heating food in plastic containers can increase the release of plastic particles and chemicals into your meal. Glass and ceramic are better choices.
4. Upgrade your kitchen – Replace older plastic food containers, cutting boards, and utensils with glass, wood, bamboo, or stainless steel as they wear out.
5. Focus on progress—not perfection – Let's be realistic: we can't eliminate microplastics completely. But every small change helps lower your exposure and supports your overall health.
👉 A 2025 study published in Nature Medicine also found micro- and nanoplastics in human brain tissue. While the study doesn't prove these particles cause disease, it adds to the growing body of evidence that microplastics are making their way into our bodies—and reinforces why reducing unnecessary exposure is a smart preventive step.
One Small Change Can Make a Big Difference
You don't have to change everything overnight. Start with one simple swap this week—carry a reusable water bottle, replace one plastic food container with glass, or prepare one fresh meal using whole ingredients.
