Microplastics in Your Gut: The Invisible Threat
Written by: Vincent Pedre M.D. | July 20, 2024 | Time to read 10 min
Microplastics are everywhere! They have become a ubiquitous presence in our environment, infiltrating every corner of the planet—from the deepest oceans to the highest mountains.
These tiny plastic particles, often less than 0.2 inches in size, are not just an environmental issue but a significant health concern as well. Recent studies have started to uncover the alarming ways in which microplastics can impact our health, particularly gut health.
In this blog post, I’m uncovering the overlooked connection between microplastics and gut health, shedding light on the potential risks and offering actionable solutions to protect yourself.
The presence of microplastics in our food, water, and even air means that ingesting them is INEVITABLE. According to a recent study published in Environmental Science & Technology, there is a significant correlation between microplastic concentration in feces and inflammatory bowel disease (IBD) status. The higher the level of microplastics, the worse the disease.
The findings are mind-blowing and they raise crucial questions about the role of microplastics in gut health and diseases. Stay with me to discover which microplastics are likely accumulating in your body and, most importantly, how to protect yourself.
The Impact of Microplastics on Gut Health
Microplastics can wreak havoc on the gut microbiome, the community of microorganisms living in our intestines that play a crucial role in digestion, immunity, and overall health. When microplastics enter the digestive system, they can alter the composition and function of the gut microbiota, leading to dysbiosis—a harmful imbalance of gut bacteria. This imbalance can trigger inflammation, which is a key factor in many chronic diseases, including IBD. Simply put, microplastics are TOXIC.
Research on zebrafish and mice has shown that exposure to microplastics can lead to gut microbiota dysbiosis, inflammation, and decreased mucus secretion in the gut. By the way, mucus provides a protective layer that keeps the bad bugs in the gut away from the stomach lining — so it’s super important to have a healthy mucus layer.
These changes can compromise the integrity of the gut lining, making it more permeable and allowing harmful substances to enter the bloodstream. This condition, known as " leaky gut", can contribute to systemic inflammation and increase the risk of various health problems. Leaky gut is playing in the background of most chronic diseases that people face in our modern world.
The unbelievable results from the 2022 study
The study conducted an in-depth analysis of the characteristics of microplastics in the feces of patients with IBD and healthy individuals. The key findings include:
1. Microplastic Concentration
The fecal microplastic concentration in IBD patients was significantly higher (41.8 items/g dm) compared to healthy individuals (28.0 items/g dm). This suggests that individuals with IBD may either ingest more microplastics or have a reduced ability to expel them from their bodies.
2. Types of Microplastics
The study identified 15 types of microplastics in feces, with poly(ethylene terephthalate) (22.3–34.0%) and polyamide (8.9–12.4%) being the most prevalent. These materials are commonly used in plastic packaging, textiles, and other consumer products.
3. Shapes of Microplastics
The primary shapes of microplastics detected were sheets and fibers, which are typical of materials used in packaging and clothing. This highlights the role of everyday plastic products as significant sources of microplastic pollution.
4. Sources of Exposure
Plastic packaging of drinking water and food, as well as dust exposure, are one of the main sources of human exposure to microplastics.
5. Health Implications
Microplastic exposure may be related to the disease process. It is also possible that IBD exacerbates the retention of microplastics in the body. This creates a vicious cycle that we definitely want to avoid. Continue reading to learn how to break free from it.
Case Study: What Zebrafish Teach Us about Microplastics & Bad Bacteria
A study on zebrafish exposed to microplastics found significant changes in their gut microbiota. The fish exhibited increased levels of harmful bacteria such as Staphylococcus and reduced levels of beneficial bacteria like Parabacteroides. These changes were associated with increased intestinal inflammation and reduced mucus secretion, which protects the gut lining.
Microplastics and Metabolic Disorders
The impact of microplastics on gut health is not limited to inflammation and microbiota imbalance. There is growing evidence that microplastics can also affect metabolic health, potentially contributing to obesity and related disorders, like diabetes and heart disease. In many animal studies, such as this one, exposure to microplastics has been linked to alterations in lipid metabolism and increased body weight. Microplastics may interfere with the body's ability to regulate fat storage and energy balance, leading to weight gain and metabolic issues.
In addition, microplastics can act as carriers for other harmful chemicals, such as phthalates and bisphenol A (BPA), which are known to disrupt endocrine & immune function and contribute to metabolic disorders as well as autoimmunity. This combined exposure can exacerbate inflammation, impair glucose metabolism, and further disrupt lipid homeostasis.
Case Study: What Mice Teach Us about Microplastics & Getting Fat
In a study involving mice, exposure to microplastics led to significant changes in lipid metabolism and increased body weight. The mice exhibited higher levels of adipose tissue (aka body fat) and alterations in genes related to fat storage and metabolism. These results suggest that microplastics can disrupt normal metabolic processes and contribute to obesity.
How to Reduce Microplastic Exposure
Microplastics are in tires, paint, clothing, plastic bottles, water, aerosols, and fertilizers. Given the pervasive nature of microplastics, completely avoiding them is nearly impossible. They cause oxidative stress, neurotoxicity, reproductive toxicity, carcinogencity, and altered metabolism, among other things.
Are we simply doomed?! Obviously, however, there are steps you can take to minimize your exposure and protect your gut health:
1. Filter Your Water
Use a high-quality water filter to reduce the presence of microplastics in your drinking water. Studies have shown that bottled water often contains higher levels of microplastics compared to tap water. Using a filter can help mitigate this risk.
2. Choose Fresh, Unpackaged Foods
Opt for fresh produce and bulk items to avoid plastic packaging. Plastics used in food packaging are a significant source of microplastic contamination.
3. Avoid Plastic Bottles and Containers
Use glass, stainless steel, or other non-plastic alternatives for storing food and beverages. Plastic containers can leach microplastics and harmful chemicals, especially when heated.
4. Limit Processed Foods
Processed foods are more likely to contain microplastics due to their extensive packaging (like wrappers) and processing methods. Choosing whole, unprocessed foods will significantly reduce your exposure.
5. Clean Air Quality
Use air purifiers to reduce airborne microplastics in your home. Microplastics are not only present in water and food but can also be inhaled through the air. Maintaining good indoor air quality can help minimize this risk.
6. Support Plastic Reduction Initiatives
Advocate for policies and practices that reduce plastic use and pollution. Supporting environmental initiatives can help reduce the overall presence of microplastics in the environment.
Example: Community Initiatives for Plastic Reduction
In the coastal town of Monterey, California, a community initiative aimed at reducing plastic pollution has led to significant changes. The town implemented bans on single-use plastics, promoted the use of biodegradable alternatives, and organized beach clean-ups to remove plastic waste. As a result, the local environment saw a marked decrease in plastic pollution, benefiting both marine life and the health of residents.
This particularly hits home, because the state of Miami Beach, where I grew up, is in danger due to plastic pollution. Every single day, plastic bottle caps, torn plastic bags, and pieces of plastic wash up on the seashore. I can only imagine how much plastic is floating in the ocean, getting into our fish, and destroying our natural habitats.
What did Jane do?
Consider the case of Jane, a 35-year-old who decided to minimize her plastic use after learning about the dangers of microplastics. She started by replacing plastic water bottles with a stainless steel one and switched to buying fresh produce instead of pre-packaged foods. Jane also invested in a high-quality water filter and an air purifier for her home. Over time, she noticed improvements in her digestive health and overall well-being, attributing these changes to her reduced exposure to microplastics.
