How Microplastic Affects Your Body and Gut and What You Can Do In this episode of the Listen To Your Gut podcast, I spoke with probiotic pioneer Natasha Trenev about a deeply concerning topic: microplastic particles in the human body and their effect on our health. We’ve talked about many issues over the years, but this one has shocked us! The presence of microplastics in food, water, and the human bloodstream is not just a trend or headline. It is a crisis that affects the digestive system, the immune system, and every part of the body. You can watch the video of our discussion: Or listen to the podcast: Chapters (Main Topics) Microplastics in the blood, brain, placenta, and breast milk How microplastics enter the human body through food and water Sea salt vs. mined salt: choosing the safer option Dangers of bottled water and plastic packaging Why microwaving food in plastic is harmful The link between microplastics and damage to the gut microbiome How precision probiotics can help protect the digestive system The growing impact of environmental toxins on chronic illness Easy lifestyle changes to reduce microplastic exposure The importance of packaging, filtration, and mindful consumption Microplastics Found in Organs, Blood, and Brain Recent studies have found microplastic particles in almost every part of the human body. These include the brain, liver, kidneys, and even the placenta and breast milk. One study tested 23 men and 47 dogs. Every testicle examined had microplastic particles inside. That level of contamination shocked me. Another recent study reported that 4 out of 45 people had toxic levels of microplastics in their blood. Researchers at Harvard found that if microplastics are in your blood, your risk of heart attack or stroke increases by 450%. These tiny particles can even cross the blood-brain barrier. Natasha added that this is a serious concern. The biological systems of the body are constantly working, every second. Anything the body cannot digest, utilize, or eliminate will irritate or disrupt those processes. Microplastics are foreign to the human body. They are not meant to be there. Where Are These Microplastics Coming From? Natasha reminded me that this problem is not new. She spoke out over 50 years ago against the use of plastic in health food stores. No one listened then. Now, the plastic waste floating in the Pacific Ocean is said to be the size of the state of Texas. That plastic waste breaks down into microplastic particles. These particles are then found in bottled water, plastic packaging, and even our food supply. Microplastics are also entering the food chain through marine life. Fish like catfish and shellfish are filter feeders. They consume what’s at the bottom of the ocean, where microplastics settle. When we eat those animals, we take in those plastic particles too. This affects our digestive system and our immune system in ways we are just beginning to understand. Even salt is affected. Ocean salt, such as sea salt or Celtic sea salt, comes from evaporated seawater. That water may contain nanosized plastic particles. So those particles are left behind in the salt crystals. That’s why I now use only salt that comes from underground, ancient deposits that have not been exposed to microplastic pollution. Plastic Packaging and Bottled Water: Hidden Dangers We also talked about bottled water. Natasha and I both avoid drinking from plastic bottles. Even when water is cold, the chemicals from plastic can leach into the water. And our bodies absorb liquids faster than solids, which increases the risk. I buy water that comes in glass bottles, both for home and on the go. Natasha does the same. Plastic packaging is another major source of exposure. Natasha made the decision years ago to package her Natren probiotics in dark amber glass bottles with tin lids. She refuses to use plastic containers or plastic lids. She explained that tin lids offer the best protection for probiotics an
