Microplastics: A Hidden Health Risk
Microplastics—tiny particles of plastic that don't break down in the environment—have been found everywhere from deep ocean trenches to the human body. They're in the water and food we consume and the air we breathe. Not surprisingly, growing evidence suggests that microplastics can disrupt health in various ways. Based on early studies, potential health risks may include inflammation, immune system impairment, changes in metabolic function and harm to reproductive, digestive and respiratory health.
Key Facts
- 400 million tons — The approximate amount of plastic produced globally each year.
- 2,400 — The number of chemicals used to make plastic that are considered potentially toxic.
- 93% — The percentage of plastics that degrade into microplastics and pollute the earth's ecosystems.
- 1 credit card — The estimated volume of microplastics a person ingests each week.
How Does Plastic Get Inside Us?
- Ingested through food and water and the use of plastic cookware, utensils and food packaging.
- Inhaled via dust saturated with invisible plastic particles (for example, from walking across synthetic carpet).
- Absorbed through the skin via sweat glands, hair follicles and microscopic wounds.
Reduce Your Exposure
Food and Drink
- Skip bottled water.
- Reduce your intake of ultraprocessed foods.
- Eat a fiber-rich diet to move microplastics through your system quickly.
- Choose loose-leaf tea over tea bags, which often contain plastic fibers.
Meal Prep
- Choose stainless steel, cast-iron or enamel-coated cookware instead of nonstick.
- To store or reheat food, use glass or ceramic containers instead of plastic containers or plastic wrap.
- Avoid plastic utensils and cutting boards.
Daily Habits
- Wear clothes made of natural (not synthetic) textiles, especially for exercise.
- Vacuum with a HEPA filter.
- At the grocery store, choose foods and beverages in glass jars when possible.
Personal Care
- Use tampons or pads made from organic materials.
- In skincare products, avoid ingredients such as polyethylene, polypropylene, nylon and acrylates.
