In today’s modern world, as convenient as it may be, plastic poses a significant threat to our health that often goes unnoticed. Recent studies have shed light on the presence of microplastics and nanoplastics (MNPs) in the human body and their detrimental effects.
MNPs, tiny particles of plastic less than 5 millimeters in size, have been discovered in various human tissues and fluids. Studies have shown that MNPs can enter our bodies through ingestion, inhalation, and even skin exposure. This means that every time we consume food or water, breathe in polluted air, or come into contact with plastic materials, we may be introducing these harmful particles into our system.
Research has revealed alarming findings regarding the presence of MNPs in human tissues such as the placenta, lungs, and liver. Additionally, MNPs have been detected in breast milk, urine, and blood, highlighting the widespread contamination of our bodies with these minuscule plastic particles.
But what exactly are the implications of MNPs on our health? Recent studies conducted on preclinical models suggest that MNPs could pose a new risk factor for cardiovascular diseases. In vitro studies have demonstrated that certain MNPs can induce oxidative stress, inflammation, and cell death in endothelial and vascular cells. These effects could ultimately lead to the development of cardiovascular conditions such as heart disease and stroke.
Animal models further support these findings, showing that exposure to MNPs can result in altered heart rate, impaired cardiac function, myocardial fibrosis, and endothelial dysfunction. These changes in the cardiovascular system could have serious consequences for overall health and wellbeing.
Just released in the New England Journal of Medicine (NEJM) is a new study showing the horrific consequences of microplastics. Over 300 people undergoing a procedure on a blocked carotid artery were studied. Samples of the blockage, or plaque, were obtained and tested for microplastics. Two groups were created: Those with microplastics and those without. The groups were then followed for three years for outcomes such as heart attack, stroke or dying.
People without microplastic detected in their artery had a 7.5% chance of these outcomes versus 20% chance of these outcomes in people with microplastic.

The implications of MNPs on human health are concerning, and urgent action is needed to address this growing issue. Efforts to reduce plastic pollution at its source are crucial in preventing further contamination of our environment and bodies. Additionally, more research is needed to fully understand the extent of the health risks posed by MNPs and to develop strategies for mitigating their effects.
Individuals can also take steps to reduce their exposure to MNPs by minimizing their use of plastic products, opting for alternatives whenever possible, and supporting initiatives aimed at tackling plastic pollution. By collectively working towards reducing plastic waste and protecting our health, we can mitigate the harmful effects of microplastics on both ourselves and the environment.
At NHD, we offer testing to determine your plastic level. BPA, or bisphenol A, detectable in your urine. If you have high levels of BPA, you need to get this figure out. Here is the link to the test that looks at BPA and phthalates from plastic plus dozens of other toxins such as pesticides, parabens and VOCs.
In conclusion, the presence of microplastics and nanoplastics in the human body poses a significant threat to our health, particularly in relation to cardiovascular diseases. As our understanding of this issue grows, it is imperative that we take proactive measures to address plastic pollution and reduce our exposure to these harmful particles. Only through concerted efforts can we safeguard our health and the health of future generations from the invisible threat of microplastics.
