Study Shows That Microplastics Can Actually Get Into Your Brain Tissue

We've heard that microplastics are everywhere. Since scientists have been investigating just how prevalent they are in our world, there has been a lot of discussion about microplastics.

One thing to remember is that plastic is ubiquitous, but microplastics can infiltrate places we never would have imagined, given their minuscule size. Due to the increase in microplastics worldwide, studies have been conducted to determine where they accumulate and how they affect our bodies.

These studies have already produced alarming results, showing that microplastics are often found inside our bodies and in our food. This is incredibly concerning, and it becomes even more frightening when considering the implications of having these plastics circulating in our bodies. Now, there is a new concern.

Recent studies have shown that microplastics are ending up in our brain tissue, which is as alarming as it sounds. Although many of us may already have microplastics in our bodies, and not all of them will necessarily cause problems, there remains a significant risk that this could lead to other health issues.

So, if you're interested in learning more about how they entered the brain tissue and what this could mean for you, stay tuned as we examine the study that provided this information.

Microplastics are indeed everywhere due to the way humans live today and the various plastic products we use.

A scientist in Brazil discovered microplastics in the brain tissue of cadavers in a published study in the JAMA Network Open journal. Research has shown that microplastics are present in nearly every organ in the body, which now officially includes the brain.

This research focused on the olfactory bulb in the brain, which is responsible for processing smells. Humans have two olfactory bulbs located above each nasal cavity, and this is where the plastics were found.

Researchers are concerned that this could allow microplastics to enter other areas of the brain through the olfactory bulb, which could pose a significant issue.

We certainly understand the concern regarding these microplastics being present in our brains and bodies.

“Previous studies in humans and animals have shown that air pollution reaches the brain and that particles have been found in the olfactory bulb, which is why we believe the olfactory bulb is likely one of the first points for microplastics to enter the brain,” said lead study author Dr. Thais Mauad.

They examined samples from fifteen cadavers and found that eight out of the fifteen had microplastics in their olfactory bulb tissue. The most common type of plastic identified was polypropylene, with the smallest particles being smaller than a human red blood cell.

“Polypropylene is everywhere—in furniture, rugs, and clothing,” Mauad stated. “We know that the place where we are most exposed to particles is indoors because our homes are filled with plastic.”

“The nose serves as a major defense mechanism to keep particles and dust out of the lungs,” wrote Matthew Campen, a toxicologist, in an email. “Thus, finding some plastics in the olfactory system, especially given their presence throughout the rest of the body, is entirely expected.”

There is considerable concern regarding what this means for humans and where these microplastics could be traveling in the body if they are being drawn in through the nose. Although this may be expected, it is still quite troubling to see how much plastic is present in our bodies, and researchers will continue to investigate the details of this phenomenon.

The Health Implications of Microplastics

Dr. Andrew Weil, a leading expert in integrative medicine, emphasizes the need for awareness regarding microplastics in our environment. He states, "Microplastics can have profound implications on human health, potentially affecting neurological functions and overall well-being." Studies indicate that these tiny particles may not only be ingested but can also enter the bloodstream, leading to a range of health issues, including inflammation and oxidative stress.

To mitigate exposure, Dr. Weil recommends consuming organic foods, using glass or stainless steel containers for food storage, and advocating for policies that reduce plastic use, which can significantly lower microplastic contamination.

A notable voice in environmental science, Professor Richard Thompson, asserts that the pervasiveness of microplastics is alarming. He notes, "The accumulation of microplastics in our ecosystems is a clear indicator of our consumption habits. Addressing this issue requires both personal and collective action to reduce plastic waste." His research indicates that microplastics can travel through food chains, ultimately impacting human health.

He suggests individuals can take practical steps by participating in local clean-up efforts and advocating for sustainable practices in their communities. This proactive approach not only creates a healthier environment but also fosters awareness about the broader implications of plastic pollution.

Understanding the Deeper Patterns

The emerging research on microplastics and their potential entry into human brain tissue raises significant health concerns. Experts like Dr. Andrew Weil and Professor Richard Thompson highlight the urgent need for individual and societal action to combat plastic pollution. Both emphasize that reducing plastic waste is essential for protecting our health and the environment. Awareness and advocacy can lead to meaningful change, making it imperative for everyone to engage in sustainable practices, such as minimizing plastic use and supporting environmental policies. Together, we can work towards a healthier future free from the threat of microplastics.
