Overview

In this episode of "Wellness Unmasked," Dr. Nicole Saphier delivers a compelling examination of the growing public health concerns around microplastics—tiny plastic particles present in everyday food, beverages, the air we breathe, and even our bloodstreams. Dr. Saphier dissects the latest scientific research, explores the troubling extent of microplastic contamination, and provides listeners with actionable advice to limit personal exposure.

Key Discussion Points & Insights

1. The Ubiquity of Microplastics

• Dr. Saphier debunks any suggestion that microplastic exposure is a theoretical or future problem, stating:
  • "Our exposure to microplastics—it's a real problem. And I'll be honest, I’m a little bit disappointed because the updated Maha report [...] said they’re going to put a lot of money into studying microplastics. I don’t need any more studies because I’m telling you it’s a problem." (03:04)

2. Recent Research and Shocking Findings (UK Beverage Study)

• Highlights a new UK study testing 155 different beverage samples:
  • “They found microplastics inside every sample, single one.” (04:11)
• Hot beverages, especially tea made with traditional teabags, contained the highest levels of microplastics:
  • “Teabags are one of the biggest culprits when it comes to exposure to microplastics. [...] The amount of microplastics are the highest than any other beverage.” (05:20)
• Warm temperatures accelerate microplastic release from packaging into drinks.

3. Microplastics Detected In the Human Body

• Recent studies found microplastics in the blood of 89% of healthy adults.
  • “About 4 particles per milliliter of blood. And maybe that doesn’t sound like a lot, but you have a lot more than a milliliter in your body circulating.” (06:10)
  • “People with the higher levels, they also had more inflammatory markers in their blood. They also had higher risk of blood clotting.” (06:45)
• Microplastics also found in placentas, organs (liver, kidneys, lungs), and, most concerningly, the brain.
  • “This one post mortem research study [...] revealed that micro and nanoplastics [...] can actually reach the human brain. This is a big deal.” (09:50)
  • “There were 7 to 30 times more microplastics in brain tissue than in the liver and the kidneys. That's a problem.” (10:15)

4. Potential Health Impacts

• Correlation between microplastics in blood and increased inflammation, clotting disorders, and potentially chronic disease.
  • “Research are discovering that people with the higher levels [...] had more inflammatory markers in their blood. [...] It’s going to trigger the clotting cascade, which happens with inflammation, and you’re going to have systemic inflammation and maybe an increased risk of clotting disorders.” (06:45)
• In the brain, patients with a history of dementia were found to have higher microplastic loads.
  • “They looked at the post mortem patients who had the microplastics in the brain and yep, you guessed it, the patients who had a history of dementia had more microplastics in their brain. So what does this mean? I don't know.” (10:40)
• Profound concern over links to conditions characterized by inflammation, such as diabetes, cancers, autoimmune diseases, and dementia.
• Dr. Saphier draws a parallel between the delay in acting on microplastics and the decades-long denial of the dangers of cigarette smoking.

5. Limitations of Current Response and Call for Action

• Expresses frustration with governmental focus on further studies instead of immediate action.
  • “We can’t wait 10 to 20 years to continue to study. We have to start taking some action now to do everything we can to decrease our exposure to microplastics.” (12:22)
• Stresses importance of personal and collective action, since policy change is slow:
  • “I guess here's the takeaway. I would love to say that the government or whomever is going to start focusing on microplastics and push for smarter policies to really curb the whole single use plastics and all of that. But the reality is I don't think it's very high on their priority.” (19:10)

Notable Quotes & Memorable Moments

• On the pervasiveness of the problem:
  • "If you think that you don’t have microplastics in your blood, you do. [...] It’s probably in your brain too." (13:33)
• On societal dependence on plastic:
  • "We have just become a society where we are incredibly dependent on plastic products." (14:56)
• The parallel with the tobacco industry:
  • "I can't even begin to think about how awful it was, how long it took for people to finally say, huh, you know what? Cigarette smoking, that's probably not good for us." (12:57)
• Empowerment, not fear:
  • “I'm not sharing this to just scare you, but I want to empower you.” (15:35)

Actionable Advice to Reduce Exposure (with Practical Explanations)

• Ditch Plastic Teabags
  • “Let’s stop using tea bags. This breaks my heart. I love hot tea... but plastic tea bags? Terrible. Absolutely terrible.” (15:45)
  • Suggests switching to loose leaf tea or using liquid herbal tinctures.
• Avoid Plastic in Food and Beverage Preparation
  • “Try not to use plastic cups, plastic tops. [...] Maybe bring your own stainless steel or glass bottle. Trying not to use those disposable bottles.” (17:45)
  • “Stop microwaving things in plastic containers. Let’s do it. Let’s stop.” (18:22)
• Clothing and Household Microplastics
  • “Consider washing your synthetic clothing less often now. [...] That whole athletic athleisure wear that everyone's into these days, there is actually chemicals in it that are plastics that are being shown to stay on our skin and absorb that way.” (18:55)
  • Recommends checking skin product ingredients.
• Air Quality
  • “A big thing is, and it's also just a good thing in general is keep your air clean. [...] Make sure you're changing your HVAC filters regularly.” (19:40)
  • Use air purifiers, especially in homes with allergies.
• Car Interior Exposure
  • “If you have closed your doors, close your windows and your car has heated up, you have a lot of plastic in your car, so you're aerosolizing a lot of that plastic. [...] As soon as you get in the car, you can also roll down your windows and just try and kind of let everything escape the car.” (20:20)

Final Takeaway

“The plastic problem, it’s not just some pipe dream that we hear about about keeping the ocean clean. It’s actually just everywhere. It’s in our blood, it’s in our lungs, it’s even in our brains. And as we continue to see more people diagnosed with cancer and dementia, now is the time to take every step we can to limit exposure both individually but also collectively.” (20:50)

Dr. Saphier leaves listeners with a clear message: the evidence for microplastic contamination and its potential harm is already compelling. While waiting for sweeping policy changes may take years, practical everyday steps—like switching to loose leaf tea, avoiding plastic packaging, improving indoor air quality, and being mindful of household plastics—can help lessen the risks for ourselves and our families.
