Microplastics in Your Diet? Simple Steps to Reduce Exposure and Protect Your Health

Microplastics have infiltrated nearly every corner of our lives, including the food we eat and the water we drink. While completely avoiding these tiny plastic particles may be impossible, there are practical steps you can take to significantly reduce your exposure and safeguard your health. From ditching bottled water to rethinking how you store and heat food, small changes can make a big difference.
Tap Water: A Safer Choice
One of the biggest sources of microplastics is bottled water. Shockingly, a single liter of bottled water can contain up to 240,000 tiny plastic particles, most of which are invisible to the naked eye. While tap water isn’t entirely free of microplastics, it contains far fewer particles. Using a high-quality water filter can remove up to 90% of plastic debris. Boiling water before consumption may also help, though experts warn against heating plastic pipes or containers, as this can release harmful chemicals. In most countries, tap water is a safe, regulated, and eco-friendly alternative to bottled water.
Rethink Plastic Food Containers
Many of us store leftovers in plastic containers and reheat them in the microwave, but this common practice could be exposing us to millions of microplastic particles. Research shows that heating plastic releases these particles into food within minutes. To reduce exposure, switch to glass or ceramic containers for storing and reheating food. Additionally, avoid storing acidic foods like tomato sauce or hot meals in plastic, as heat and acidity can cause more plastic chemicals to leach into your food.
Be Mindful of Salt and Spices
Even your salt and spices might be hiding microplastics. A 2023 study found plastic particles in every type of salt tested, with Himalayan pink salt and black salt containing the highest levels. While iodized table salt had the least, it’s still worth opting for high-quality, less-refined salts and washing spices before use. Purchasing from reputable sources can also help minimize your exposure.
Choose Fresh Over Processed Foods
Ultra-processed foods are another major source of microplastics. A study analyzing 16 protein-rich processed foods found microplastics in every sample, with breaded shrimp being a notable offender. The rule of thumb is simple: the less processed your food, the fewer microplastics it’s likely to contain. Fresh vegetables, fruits, and whole grains are not only healthier but also safer choices when it comes to reducing plastic contamination.
Swap Plastic Tea Bags for Loose-Leaf Tea
Your daily cup of tea might be contributing to your microplastic intake. Plastic tea bags, such as those made from nylon, release billions of microplastic and nanoplastic particles when steeped in hot water. To avoid this, opt for loose-leaf tea, which is free from plastic and often offers a richer flavor.
Small Changes, Big Impact
While microplastics are pervasive, taking these simple steps can help you significantly reduce your exposure. Choose fresh, minimally processed foods, store and heat meals in glass or ceramic containers, and drink filtered tap water. By making these small but impactful changes, you can protect your health and contribute to a cleaner environment.
