Microplastics: An Unseen Part of Our Lives and Bodies
Microplastics have moved beyond being solely an environmental concern; they’ve become an undeniable part of our daily existence and, disturbingly, a component within our own bodies.
Research suggests that each person takes in an amount of microplastic annually equivalent to roughly 50 average plastic bags. These tiny particles enter our systems through the food we eat, the water we drink, and even the air we breathe. In today’s world, it’s almost impossible to completely avoid contact with microplastics. This reality increasingly prompts scientists to consider if we can at least partially lessen their harmful effects on the body.
These microscopic plastic particles have been found in nearly every part of the human body, from our bloodstreams to our intestines and even the brain. They carry hazardous chemicals, including phthalates and bisphenol A, both known for their potential to disrupt hormonal balance. Some of these chemicals are recognized as harmful to human health and the environment. Studies indicate that microplastics can trigger inflammation, upset the gut’s natural balance, and influence the endocrine system. In 2024, researchers observed that individuals with elevated levels of microplastics in their bodies faced an almost fivefold increased risk of stroke or heart attack. The primary suspected cause for this is the ongoing inflammation brought about by exposure to these plastic particles.
However, there is also some reassuring information. Larger microplastic particles—such as bits from plastic cutting boards that might enter food—typically pass through the intestines and are naturally expelled from the body. Furthermore, even the harmful chemical compounds released by plastics don’t linger in the body for excessively long periods. This holds true if a person consciously limits the use of plastic utensils and packaging whenever possible, and adheres to guidelines when using them, such as not pouring overly hot liquids into plastic containers. Nevertheless, some nanoparticles are small enough to penetrate cells and move throughout the body, making the issue considerably more complex.
Currently, there isn’t a direct remedy to remove microplastics from the body. However, studies suggest that certain dietary habits can help the body manage their negative impact. One promising avenue is combating the chronic inflammation associated with microplastics through the use of antioxidants. Scientists have discovered that anthocyanins, plant compounds found in blue and purple berries, may help mitigate the negative effects of microplastics on the reproductive system. These compounds might also offer benefits for blood sugar regulation, heart health, and the prevention of brain-related conditions.
While proper nutrition cannot completely rid the body of plastic particles, it significantly helps strengthen the body’s natural defenses. For instance, the Mediterranean diet, rich in fresh vegetables, fruits, legumes, fish, and whole grains, supports a stronger immune system and a healthy gut. It can also help reduce inflammation and bring hormonal balance. Experts are confident that a balanced diet makes the body more resilient to a wide range of external stressors, including the effects of microplastics.
As science continues to explore the full extent and mechanisms of microplastics’ impact on human health, individuals can take steps today to minimize their personal risks. Paying attention to what we eat, choosing safer dishes and food packaging, and being mindful of our food and water sources can not only help counter the dangerous effects of microplastics but also generally improve our health. Plastic has undeniably become a part of our modern world, but awareness and self-care can lessen its adverse influence on our bodies.
Incidentally, scientists recently reported finding a method to remove another persistent modern industrial byproduct from the body – so-called “forever chemicals.”
