The Dirty Truth About Microplastics: 3 Alarming Facts You Need to Know

  • 28 June 2025

Microplastics are tiny plastic pieces that end up in our food, water, and even the air we breathe. Scientists say people consume thousands of these plastic bits every year. The worst part? You might be eating or drinking them daily without realizing it. These tiny pieces, smaller than a grain of rice, come from broken-down plastic items, synthetic fabrics, and industrial waste.

Researchers have found microplastics in deep-sea creatures, arctic ice, and even inside the human body. If they’re everywhere, how can you protect yourself? Let’s take a closer look.

1) Where Do Microplastics Come From?

If you drink water, eat food, or even breathe, you’re exposed to microplastics. They come from broken-down plastic products, synthetic clothing fibers, and industrial waste. Here’s where they hide in everyday life:

  • Bottled & tap water – Some bottled water brands have thousands of plastic particles per liter. Even tap water can contain microplastics due to old pipes and pollution.
  • Tea bags & coffee pods – Some tea bags shed billions of tiny plastic pieces into your drink. Many coffee pods are made with plastic that breaks down in hot water.
  • Seafood – Fish and shellfish absorb plastic from the ocean, and when we eat them, we take in those plastics too. Scientists say regular seafood eaters ingest thousands of microplastics a year.
  • Salt & sugar – Some brands contain plastic bits from ocean pollution and food processing. Sea salt has been found to have especially high levels.
  • Fruits & vegetables – Plants absorb microplastics from contaminated soil and water. Studies show that root vegetables, like carrots and radishes, absorb the most.
  • Meat & dairy – Animals that eat contaminated feed and drink polluted water may have plastic particles in their meat and milk. Processed dairy products, like cheese and yogurt, may also contain plastic from packaging.

Even household dust contains microplastics, so just breathing indoors can add to your exposure.

Grab our free checklist to see the top 9 ways to avoid microplastics in your food, water, and home!

2) How Do Microplastics Affect Your Health?

Scientists have found microplastics in the brain, lungs, and even the bloodstream. These tiny plastics don’t just pass through the body; they can build up over time. Here’s how they might affect your health:

  • Digestive issues – Microplastics can irritate the gut and disrupt healthy bacteria, possibly leading to inflammation and digestion problems.
  • Hormone imbalance – Many plastics contain chemicals that mess with hormones, which could lead to weight gain, fertility issues, and other health problems.
  • Heart disease risk – Some studies suggest that microplastics in the bloodstream could increase inflammation, raising the risk of heart disease and strokes.
  • Brain health concerns – Plastic particles have been found in brain tissue, and scientists worry they could affect memory, focus, and long-term brain health.
  • Breathing problems – Inhaling microplastics can lead to lung inflammation and make asthma worse. People who work in factories with lots of plastic exposure are at higher risk.
  • Weakened immune system – Some researchers believe microplastics could make it harder for the immune system to fight off infections and diseases.

Scientists are still studying the long-term effects, but early research shows microplastics could be dangerous to our health.

3) How to Reduce Your Exposure to Microplastics

You can’t avoid microplastics completely, but small changes can help lower your intake. Here’s what you can do:

  • Use glass or stainless steel bottles – Plastic bottles release microplastics, especially when left in the sun or reused.
  • Choose loose-leaf tea – Many tea bags contain hidden plastic that dissolves in hot water. Use a metal or glass tea strainer instead.
  • Filter your water – A high-quality water filter can help remove tiny plastic particles.
  • Eat smaller fish – Larger fish, like tuna, have more plastic buildup over time. Choose smaller fish like sardines or anchovies instead.
  • Avoid plastic-wrapped foods – Buy fresh produce and bulk items whenever possible. Store food in glass or stainless steel containers.
  • Support sustainable brands – Some companies use eco-friendly packaging and less plastic waste. Look for brands that make sustainability a priority.
  • Use better kitchen tools – Plastic utensils and non-stick pans can break down over time, releasing microplastics into food. Use stainless steel, wood, or cast iron instead.
  • Keep your home clean – Vacuum and dust regularly to reduce microplastics in household dust.

Final Thoughts

Microplastics aren’t going away anytime soon, but you don’t have to keep consuming them. While avoiding them entirely is impossible, small swaps—like switching to reusable bottles and avoiding plastic-heavy foods—can lower your exposure. The more you know, the better choices you can make for your health and the planet.

Even small steps make a difference. By using less plastic and supporting sustainable choices, you’re protecting both yourself and the environment. If enough people take action, companies and governments may push for stronger regulations to reduce plastic pollution. Start today with one simple change.
