Microplastics are tiny plastic particles that are showing up in unexpected places, including our food. Recent research highlights a troubling trend: a study found these particles in human brain tissue. It’s estimated that people might consume between 39,000 and 52,000 microscopic plastic pieces each year. When we account for what we breathe in, that number can rise to as high as 121,000!
These particles are not just floating around—they end up in our bodies through various channels, like the water we drink and the food we eat. Microplastics can contaminate crops where plastic is used in farming, as well as seafood due to pollution in the oceans. Dr. Joseph Mercola, an osteopathic physician, emphasizes that while there’s no "safe" threshold for microplastic exposure, keeping it to a minimum is a sensible choice.
Common Foods Containing Microplastics
-
Seafood: Oceans are saturated with microplastics, which fish and shellfish mistake for food. A study from Portland State University found microplastics in 180 out of 182 seafood samples tested.
-
Tea Bags: Many tea bags are made from polypropylene. Research suggests they can release billions of plastic particles when steeped in hot water. Consider switching to loose-leaf tea to avoid this.
-
Rice: A University of Queensland study noted that a half cup of rice may contain 3 to 4 milligrams of plastic—this figure shoots up to 13 milligrams for instant rice. Washing rice before cooking can reduce this contamination.
-
Salt and Sugar: A staggering 90% of salt brands tested worldwide contain microplastics, likely due to environmental contamination. Similarly, sugar has been found to contain these particles too. Opt for glass or cardboard packaging to cut down your exposure.
-
Bottled Water: Research shows bottled water can contain about 240,000 plastic particles per liter. Many bottled water brands use polyethylene terephthalate (PET), which can break down under heat or pressure.
-
Honey: Even honey isn’t immune. Bees can ingest microplastics from the environment, which may then make their way into honey.
-
Fruits and Vegetables: A study showed that apples and carrots can contain microplastics. Plants can absorb these tiny particles from contaminated soil.
- Proteins: Nearly 88% of both animal and plant-based proteins tested have microplastics, with the highest levels in processed foods.
What Does This Mean for Your Health?
Microplastics could potentially harm our health. They may accumulate in the body and cause inflammation or tissue damage and could lead to hormonal imbalances due to harmful chemicals found in plastics. While experts urge caution, the long-term health effects of microplastics are still under investigation.
Tips to Reduce Microplastic Intake
- Be Cautious with Shellfish: Limit consumption of shellfish known to have higher microplastic levels.
- Choose Glass or Stainless Steel: Use glass containers for food storage to avoid plastic contamination.
- Wash Produce: Rinse fruits and vegetables thoroughly. Peeling can further reduce risks.
- Filter Your Water: If you can, drink filtered tap water rather than bottled.
Conclusion
Microplastics are pervasive and hard to avoid. While we still have much to learn about their effects, being proactive about minimizing exposure can help safeguard your health. A balanced diet focused on fresh, unprocessed foods is still key to a healthy lifestyle, even in an age of microplastic contamination.
