Plastic is everywhere—in the air, the sea, and, as recent studies have shown, probably in our bodies. Microplastics, which are tiny plastic particles, can enter our digestive system when we accidentally eat plastic or consume food and drinks contaminated by microplastics. While small pieces of plastic will likely pass through the digestive system without causing harm, larger pieces may lead to gastrointestinal issues, allergic reactions, and toxicity symptoms. Moreover, the chemicals released by plastics when they break down in our bodies can have serious long-term health effects, including asthma, breast cancer, and prostate cancer.

Microplastics enter the body via food, water, and air
Microplastics are extremely small pieces of plastic debris that can be up to 5mm in length, but are more commonly found on a smaller scale, reaching less than 1 micrometer (0.001mm) in size. These minuscule particles can enter our bodies through various pathways, including ingestion, inhalation, and even consumption of contaminated food and water.
One of the primary ways microplastics enter our bodies is through the food we eat. Contamination can occur when food comes into contact with plastic during production, packaging, or storage. This is particularly prevalent in seafood, especially shellfish like mussels and oysters, due to the higher concentration of plastic pollution in coastal waters. Microplastics have also been detected in other food items such as sea salt, honey, and beer, highlighting the widespread presence of plastic pollutants in our food systems.
Another route of entry for microplastics is through the water we drink. Plastic pollution in water sources, including bottled and tap water, can result in the presence of microplastics in our drinking water. These tiny plastic particles can then be ingested, potentially leading to health concerns.
Additionally, microplastics can enter our bodies through the air we breathe. Plastic debris in the environment can break down into microscopic particles that become airborne and are subsequently inhaled. This can occur in indoor and outdoor settings, as plastic fibres and particles are commonly found in the air we breathe.
While the immediate health effects of ingesting small pieces of plastic may not always be severe, there are potential long-term consequences. Research suggests that the chemicals released by plastics when they break down in our bodies can lead to serious health issues, including premature births, asthma, and even certain types of cancer. The impact of microplastics on human health is an area of ongoing research, and the full extent of their effects is yet to be fully understood.

They can cause allergic reactions and toxicity
The human body can accidentally ingest plastic in various ways, such as by consuming food and water contaminated by microplastics or accidentally eating plastic itself. Microplastics are extremely small pieces of plastic debris, commonly found in the nanoscale range, that can enter our bodies through contaminated food and drinks. These tiny particles can then be absorbed into our intestines and travel to other body parts through our blood circulation.
Once inside the body, plastic can cause allergic reactions due to certain additives used in their production. Some plastic additives, such as phthalates, are known to increase the risk of asthma in children and premature births when pregnant women are exposed.
Toxicity symptoms can also occur if toxic plastics like PVC (polyvinyl chloride) are ingested. Symptoms of toxicity can include dizziness, headaches, respiratory problems, and even poisoning. The chemicals released by plastics when they break down in our bodies can interfere with hormone functionality, leading to the development of cancers, particularly breast and prostate cancers.
It is important to note that the effects of ingesting plastic can vary depending on the size and shape of the plastic piece swallowed. Small pieces of plastic will likely pass through the digestive system without causing harm, but sharp objects may damage the gut lining and cause internal bleeding. Monitoring symptoms and seeking medical advice if any discomfort or concerning symptoms arise is crucial.
To reduce exposure to plastic and potential health risks, individuals can be mindful of the food they consume and its packaging, as well as practice regular household cleaning to limit indoor contamination.

Microplastics can cause damage at a cellular level
Microplastics are extremely small pieces of plastic debris, often measuring less than 1 millimetre in length. They are commonly found in the environment due to the breakdown of larger plastic items. These minuscule particles can inadvertently enter our bodies through contaminated food and water, becoming a health concern. Once ingested, microplastics can cause damage at a cellular level in several ways:
Firstly, microplastics can penetrate cell membranes. Their tiny size allows them to pass through these membranes and interact directly with cells. This intrusion can disrupt normal cell functions and compromise the integrity of various organs and tissues in the body.
Secondly, microplastics can act as carriers for harmful chemicals. As they circulate in the body, they may pick up and transport toxic substances, including endocrine-disrupting chemicals like phthalates and bisphenol A (BPA). These chemicals can interfere with hormone production and functionality, leading to the development of serious health issues such as breast and prostate cancer.
Additionally, microplastics can induce an inflammatory response in the body. When cells recognise foreign particles like microplastics, they may trigger an immune reaction, leading to inflammation and potential tissue damage. This response is similar to that seen in allergic reactions to certain plastic additives.
The impact of microplastics on cellular function can also have systemic consequences. Ingested microplastics can enter the bloodstream and reach various organs, including the brain. The accumulation of microplastics and their associated chemicals in vital organs can lead to long-term health issues, even if the initial ingestion was accidental.
Furthermore, microplastics can contribute to cellular damage by affecting gene expression. Studies have shown that exposure to certain types of microplastics can alter the expression of genes involved in critical cellular processes, potentially impacting cell growth, differentiation, and survival. These alterations may have far-reaching effects on overall health and disease development.
While the immediate health effects of swallowing larger pieces of plastic, such as gastrointestinal issues and allergic reactions, are more noticeable, the insidious damage caused by microplastics at the cellular level should not be underestimated. The pervasive nature of microplastics in our environment and their ability to infiltrate our bodies underscores the urgency of understanding and mitigating their cellular-level impacts on human health.

They can lead to long-term health issues, including cancer
Consuming plastic, even inadvertently, can have serious long-term health consequences. Plastic particles can enter our digestive system when we accidentally eat plastic or consume food contaminated with microplastics. These particles can be absorbed by the intestines and travel to other parts of the body via blood circulation. Microplastics can pass through cell membranes, potentially causing cellular-level damage.
One of the most concerning long-term health risks associated with plastic ingestion is cancer. Research has shown a link between consuming plastic and the development of breast and prostate cancer. This is due to the presence of endocrine-disrupting chemicals such as phthalates and bisphenol A (BPA) in plastics. These chemicals can interfere with hormone functionality, leading to an increased risk of cancer.
Additionally, the breakdown of plastics in the body releases harmful chemicals, which can have long-term health implications. For example, Bisphenol S (BPS), a common substitute for BPA, has been found to have negative effects on the heart, brain, and immune system. Prolonged exposure to these chemicals can potentially lead to chronic health issues, including cancer.
The impact of microplastics on human health is an emerging area of research, and the full extent of their long-term effects is not yet fully understood. However, given the ubiquitous nature of plastic pollution and the potential for bioaccumulation, the risk of developing long-term health issues, including cancer, from ingesting plastic cannot be overlooked.
While the immediate risks of ingesting larger pieces of plastic, such as gastrointestinal issues, allergic reactions, and toxicity symptoms, are more apparent, the insidious nature of microplastics and their potential to cause long-term harm should not be underestimated. It is crucial to recognize the potential dangers of plastic ingestion and take steps to reduce exposure and limit its impact on our health and the environment.

If sharp, plastic may damage the gut lining and cause internal bleeding
The ingestion of plastic, whether accidentally or through the consumption of contaminated food and water, can have serious health consequences. Microplastics, which are extremely small plastic particles, can enter our digestive system and be absorbed into our intestines. From there, they can travel throughout our bodies via blood circulation and even cross cell membranes, potentially causing cellular damage.
While most small pieces of plastic will pass through the digestive system without causing harm, sharp plastic can pose a significant risk by damaging the gut lining and leading to internal bleeding. If you experience any discomfort, difficulty swallowing, or pain after ingesting plastic, it is crucial to seek immediate medical attention. Monitoring your bowel movements can help determine if the plastic has passed through your system.
The potential health risks associated with swallowing plastic are not limited to physical symptoms. Research indicates that the chemicals released by plastics when they break down in our bodies can have long-term effects. For example, exposure to phthalates, a chemical compound used to enhance plastic durability, has been linked to an increased risk of premature births and asthma in children. Additionally, the potential interference with hormone functionality due to endocrine-disrupting chemicals like phthalates and bisphenol A (BPA) has been associated with the development of breast and prostate cancers.
To reduce exposure to plastic particles and potential health risks, it is advisable to consider the packaging of the food we consume and practice regular household cleaning. Supporting the use of biodegradable alternatives to conventional plastic products can also help minimise the ecological damage caused by plastics and decrease their presence in our environment and, consequently, our bodies.
