It’s startling to learn that humans might consume between 39,000 and 52,000 microplastic particles each year. A recent study revealed microplastics found in eight out of twelve human organ systems. These tiny particles can be in the air we breathe, the water we drink, and even the food we eat.
To dive deeper into the foods that might contain microplastics and how to lessen our intake, we consulted healthcare experts.
Are Microplastics Dangerous?
There’s no set “safe” level of microplastic consumption. Dr. Joseph Mercola, a board-certified physician, notes that exposure should be minimized when possible. Microplastics can enter our diets through various means: agricultural practices that involve plastic, contaminated water for irrigation, or the packaging of food itself. While the FDA currently indicates that the presence of microplastics in food isn’t directly threatening, it’s wise to limit consumption as much as possible.
Foods Likely to Contain Microplastics
Here are some foods that commonly contain microplastics:
Seafood
Microplastics enter our oceans through single-use plastics, which marine life mistake for food. A study from Portland State University found microplastics in 180 out of 182 seafood samples. The most common offenders were filter feeders like clams and mussels.Tip: Choose fish that aren’t filter feeders and opt for sustainable packaging.
Tea Bags
Many tea bags are made from polypropylene, releasing microplastics into your tea. A study showed that some tea bags can release billions of plastic particles when steeped in hot water.Tip: Use loose-leaf tea with a stainless steel diffuser to avoid plastics.
Rice
The University of Queensland discovered that instant rice packs can contain around 13 milligrams of microplastics per serving.Tip: Rinse rice before cooking to remove some plastic.
Salt and Sugar
About 90% of the salt brands sampled globally contained microplastics, likely due to environmental contamination and packaging methods.Tip: Buy salt and sugar in glass or cardboard packaging.
Bottled Water
Bottled water is among the most notorious sources of microplastics. A study found about 240,000 plastic particles per liter.Tip: Switch to tap water using stainless steel or glass containers.
Honey
Even honey can contain microplastics as bees can ingest particles and transfer them into hives.Tip: Consider buying honey from local beekeepers who use sustainable practices.
Fruits and Vegetables
Certain fruits and vegetables can absorb microplastics from soil. A study found that apples and carrots were among the most contaminated.Tip: Wash fruits and veggies thoroughly, and consider organic options.
Processed Proteins
Research indicates that up to 88% of protein sources, including highly processed options, contain microplastics.- Tip: Opt for whole foods and minimize consumption of ultra-processed proteins.
Health Implications of Microplastics
Despite insufficient data about long-term effects, some research suggests that microplastics can accumulate in organs and cause inflammation. They could also carry harmful chemicals that disrupt hormones.
Reducing Microplastic Exposure
To lower your exposure, consider these tips:
- Limit shellfish intake.
- Avoid plastic food storage containers.
- Skip plastic-wrapped foods.
- Choose non-plastic kitchen utensils.
The microplastic issue may seem daunting, but understanding it helps us take practical steps to improve our diets. Maintaining a balanced diet rich in whole and organic foods is essential, regardless of the inevitable presence of some microplastics.
Water Filters That Remove Microplastics
If you’re worried about microplastics in your water, some filters are designed specifically for this issue. For example, Lifestraw claims its filtration system removes 99.999% of microplastics, along with bacteria and parasites.
Understanding microplastics can empower us to make informed decisions. As awareness grows, so does the opportunity for healthier eating practices.
