A new study by researchers at the Post Graduate Institute of Medical Education and Research (PGIMER) in Chandigarh, India, has found that microplastics can seriously damage the gut. Published in the Indian Journal of Gastroenterology, the research indicates that these tiny plastic particles not only harm beneficial gut bacteria but also weaken the body’s immune system.
How Microplastics Damage Gut Health
The study reveals that microplastics, which are now widespread in our food, water, and air, can impact the gut in two key ways:
• Altered Gut Microbiome: Microplastics have been shown to reduce “good” gut bacteria while encouraging the growth of harmful ones. A balanced gut microbiome is crucial for digestion and immune function.
• Weakened Intestinal Lining: The particles can stick to the intestinal walls, leading to inflammation and a breakdown of the intestinal lining. This can allow toxins to leak into the bloodstream, a condition known as “leaky gut”.
The researchers found microplastics in human feces and even gallstones, suggesting that these particles may not simply pass through the body but can accumulate and interact with internal organs. The study also estimates that the average person ingests an amount of microplastics equivalent to a credit card every week.
Reducing Your Exposure
Microplastics are plastic particles smaller than 5 millimeters that come from common sources like single-use plastic bottles, synthetic clothes, and pre-packaged foods. While the long-term health effects are still being studied, researchers offer several simple precautions to reduce exposure:
• Avoid single-use plastics such as plastic straws, bottles, and cutlery.
• Drink filtered tap water instead of bottled water.
• Avoid heating food in plastic containers, as heat can cause plastic to break down and release more microparticles.
• Choose fresh produce over processed and packaged foods.
