I’ve been wondering for a while now: are paper coffee filters also glued? I can’t find any clue on the 'ingredient ’ list.

This is one of the easiest non toxic solutions to adopt. All you have to do is reach for unbleached brown paper filters at the grocery store instead of white. Brown filters are available from Natural Brew and Melita.

Why? Because most paper is bleached using chlorine, a process that creates dioxin and organochlorine residues. Studies have found that if you make your coffee using white paper filters, 20-40% of the filter’s dioxins (including TCDD, the most toxic dioxin) can leach into your coffee. Dioxin and organochlorine exposure is linked to birth defects, cancer, and reproductive and developmental disorders.

Thanks a lot DeStrider. Indeed I had heard of that, and have always bought brown filters. But I’ve wondered whether they are somehow ‘pressed’ or glued together at the bottom and side of the filter. I haven’t been able to find out.

So in the northwestern University nanotech cleanroom, they forbid wood or paper because wood/paper produce even more microparticles than plastics do…

No MP researcher has measured BOTH wood/hair microparticles/dirt AND microplastics in human tissue at the same time.

From Bryan Johnson and team:

I have some exciting news for you: we are launching the world’s first at-home microplastics test.

When I started doing Blueprint in 2021, measuring food and supplements for accuracy of label claims and toxins was a top priority. We needed to know for accuracy purposes, was I consuming what we thought? As you may guess, what we found was a sad reality of today’s food and supplement systems.

Very few label claims are correct and our food system is toxic. It’s even worse than you think. Some companies are oblivious to these things because they don’t test. Others know and knowingly misrepresent. We learned to never believe anything companies say and to only trust lab reports.

If you want to see what I’m talking about, we reviewed 10 top chocolate brands for heavy metals. Watch the video. You can’t unsee it. And neither can we.

After learning how dirty, toxic and misrepresented food and supplements are, we started sourcing our own ingredients and testing them ourselves. After all, I was trying to become the healthiest person on the planet and how could that happen unless we can get the exact amount of something and control the toxin load.

We got really good at this process.

After Blueprint went viral, the most common comment we got was “I want to do this! But it’s too complicated. Make it easy.” I thought about this for a long time because I’d never imagined building a food and supplement company and I was busy building the world’s first mass market brain interface.

But, as I had learned in optimizing my personal health, no one in the world had built an entire family of healthy and clean foods; enough to satisfy an entire day’s calories and nutrition. This is what I wanted someone else to have done, but of course, you usually have to build what you want to exist in the world.

Over the past year, I think we’ve built the cleanest and healthiest family of foods and supplements in the world. To make this more concrete, last month alone we spent over $50,000 testing foods for toxins and purity. That has to be unprecedented.

I previously ate Blueprint because it was the most evidence based health protocol in the world. Now I eat Blueprint also because I’m terrified of the food system, don’t really trust anyone else, and know from seeing the reports that Blueprint is verifiably clean.

Our third-party labs conduct comprehensive analyses of ingredients and products to ensure potency and purity. These tests cover a wide range of components, including macronutrients, vitamins, minerals, and standardized botanicals. The labs also screen for potential contaminants such as GMOs, heavy metals, microorganisms, pathogens, pesticides, phthalates, and aflatoxins. Additionally, they check for the presence of allergens and perform other product-specific tests as needed. This thorough examination process helps maintain the quality and safety of our food and supplement products.

Finding the right suppliers and getting these systems in place has not been easy. For example, sometimes it took us over a year to find a supplier that would meet our standards. Sometimes vendors wouldn’t even consider working with us because of our required testing. Vendors’ reluctance to embrace clean label initiatives often stems from the extra costs associated with testing for contaminants and sourcing healthier ingredients, which can impact profit margins. We select vendors who embrace these initiatives because transparency and health-conscious products benefit everyone involved.

It’s been a whoooooole thing. But we’ve been incredibly successful. Again, I think it is the best in the world.

One thing we’ve wanted to test but haven’t been able to is microplastics. We called over 50 labs and only found one that has a very limited microplastics testing ability. Far short of what we actually need. So we’re kind of flying blind, like all 8 billion of us on earth, when it comes to microplastics. The world just hasn’t set up infrastructure to test microplastics at scale.

We are speaking with a few labs to see if we can stand up the infrastructure to make this happen.

The challenge is that microplastics are everywhere. At the bottom of the ocean. On top of Mount Everest. In the rain. In our drinking water, clothes, mouthguards, skin care products and in our brains.

Without having data, we don’t know where best to focus our personal efforts to reduce microplastic exposure. For example, does 50% of the microplastics in our body come from drinking water? Or plastic water bottles? Or take out food? Or are microplastics in clothing the worst offender? We are at the very beginning of understanding.

We are transitioning to non-plastic packaging. In this process, we face challenges due to plastic’s prevalence at every level of the global supply chain and a lack of clear alternatives. While sustainable options often mean shorter shelf-life and higher costs, we’re committed to finding innovative packaging solutions that balance personal exposure, environmental concerns and are economically viable.

The good news is the industry is moving in this direction and several companies are working on new approaches. Know we’re just as eager to get rid of plastic as you are. In the meantime, I do feel comforted eating all of my Blueprint supplements and food that it’s already among the cleanest in the world.

To take matters into our own hands, we are excited to announce the world’s first mass market microplastics test, launching next week. It’s a finger prick test and tells you the kinds of microplastics circulating in your bloodstream and how you compare to others. Science begins with counting.

With this data, we will work together as a community to see if we can make headway in learning together how we can reduce our microplastic load. We may find that drinking water is the worst offender and would help us concentrate our efforts. We may find certain therapies, such as donating plasma, are great in lowering concentrations. Science begins with counting and when we have the data, we can make systematic progress.

We’re trying to do three things for you:

  1. Every calorie
  2. Every test
  3. Every friend

If you say yes to health, we want to provide you with everything you need for optimal nutrition. We want you to have the confidence that you’re getting the best in the world. We want you to have data on the health status of your body via blood work, microplastics, your speed of aging and your organ ages. We want you to have routine cancer screening via MRI and get biomarkers on your brain health plus other vital organs. We want you to get the same value as some of the most expensive executive longevity programs in the world ($50,000-$150,000) at a fraction of the cost. That’s what we’ve built for you.

A new study revealed the implications when recycled plastic from electronics is used in household items. Published in Chemosphere, researchers discovered everyday black plastic cooking utensils contain harmful flame retardants through current recycling processes.

While the toxic chemicals are banned from certain applications that don’t require flame retardants (FR), their continued use in electronics is of particular concern for researchers due to their recycled presence in other items, such as kitchen utensils, takeout containers, sushi trays and some children’s toys.

“Companies continue to use toxic flame retardants in plastic electronics, and that’s resulting in unexpected and unnecessary toxic exposures,” Megan Liu, study co-author and science and policy manager at Toxic-Free Future, said. “These cancer-causing chemicals shouldn’t be used to begin with, but with recycling, they are entering our environment and our homes in more ways than one. The high levels we found are concerning.”

The peer-reviewed study, led by scientists from Toxic-Free Future and Vrije Universiteit Amsterdam, “highlights the consequences of the lack of restrictions on toxic chemicals used in plastics in electronics such as televisions” and how recycling of these plastics “can lead to reuse in household items that do not require flame retardancy,” a press release stated.

Ugh and I drank from the teabag I asked from the Chinese restaurant today (and NOW feel slight dizziness over it), when I could have, like, not drank from it (and I also drank from the teabag someone served tea in me a week ago). Like nowadays I don’t use teabags whenever I can, but sometimes when a host offers them I do it (it’s already enough that I ask for veganism and non-plastic containers and I don’t want to go too far)… [AT LEAST acarbose makes bread acceptable again so I don’t have to request “no bread” as much anymore].

I also don’t know what kinds of teabags they use at tejava tea - they use some paper-filter which could include some plastic too, I don’t know.

[i still know the potent anti-mortality statistics from tea drinking in general which I assume is a weighted average of plastic-containing bags + looseleaf but they don’t account for our brain MP levels 2x’ing over the last 8 years…]

===
The results, depicted in Table D (Fig. 4), show that NY6-teabags released the lowest amount of NPLs (8.18 × 106 particles/mL), followed by CL-teabags (1.35 × 108 particles/mL) and PP-teabags (1.20 × 109 particles/mL). Similarly, NTA demonstrated that the number of particles detached from NY6-teabags (8.9 and 7.8 billion submicron particles) was less than those detached from PET-teabags (19.1 and 21.4 billion submicron particles) (

However, most of this data is based on studies with polystyrene, a widely used reference plastic that poorly represents the diversity in the environment (Jeong et al., 2016; Domenech et al., 2020; Liu et al., 2021; M Zhang et al., 2022a,b; Tavakolpournegari et al., 2023). In this study, several representative images in 3D were reconstructed with the Imaris software from confocal z-stacks. Images (Fig. 7) demonstrate that all three polymers interact with the cell nucleus after 24 h of a single dose of 100 μg/mL. Further statistical measures of co-localization, and interaction between different fluorescent signals, such as the Overlap coefficient (Table 1), Pearson’s correlation coefficient (Table 1 and Fig. S2), and Manders’ coefficients (Table S1) were done to understand the spatial distribution of the co-localized regions within the images. Interestingly, HT29 and HT29-MTX cell clones present the strongest overlapping response compared to Caco-2 cells. This may suggest that cell internalization and intracellular trafficking rates are cell type dependent

Interestingly, it was reported that the structure of woven filter bags (e.g., Nylon-6) was more stable compared to the non-woven ones (e.g., PET and PP), with small changes during the filter’s soaking time, which decreased the release of particulate material to the liquid phase (Mei et al., 2022). It is worth mentioning that woven fabrics are generally stronger and more durable due to the interlaced structure, having higher tensile strength and more resistance to tearing, tending to be less flexible but more stable in shape (Axinte et al., 2022). Other authors also detected fragments and fibers detaching from the main fiber, oxidation flakes, and fracture-like events

NYLON [figure 1] is SAFEST
First, the teabag filters were analyzed by SEM to detect surface irregularities that potentially induce breaks and release of particulate material. On the one hand, Fig. 1 shows the differences in shape and material among the three teabag filters (Fig. 1A–C1). On the other side, using SEM we were able to find multiple irregularities in all three teabag’s fibers looking like scales, spheres, or amorphous particles (Fig. 1 A-C.2 and 3). These structures suggest that some imperfections might appear during fiber synthesis, or filter knitting process which might depend on the polymer type. These surface irregularities have already been documented in other studies analyzing different types (both bio- and petroleum-based polymers) of teabags and filter bags (Hernandez et al., 2019; Mei et al., 2022; Banaei et al., 2023). Interestingly, it was reported that the structure of woven filter bags (e.g., Nylon-6) was more stable compared to the non-woven ones (e.g., PET and PP), with small changes during the filter’s soaking time, which decreased the release of particulate material to the liquid phase (Mei et al., 2022). It is worth mentioning that woven fabrics are generally stronger and more durable due to the interlaced structure, having higher tensile strength and more resistance to tearing, tending to be less flexible but more stable in shape (Axinte et al., 2022). Other authors also detected fragments and fibers detaching from the main fiber, oxidation flakes, and fracture-like events (Afrin et al., 2022).

UAB research has characterized in detail how polymer-based commercial tea bags release millions of nanoplastics and microplastics when infused. The study shows for the first time the capacity of these particles to be absorbed by human intestinal cells, and are thus able to reach the bloodstream and spread throughout the body.

Most restaurants in Asia use tea leaves in water. Tea bags are for personal consumption mainly.

In the USA, it’s almost all bags wherever you go for tea.

My wife bought me a very fancy Matcha tea with reishi mushroom. Came in a fine plastic tea bag. Then you guys started talking about tea bags and plastic. So now I’m just dumping the contents into hot water and drinking it off the top like a cowboy. But I don’t really know why we don’t grind it all fine and just drink it down. What’s wrong with the fiber and your gut can extract 100% right?
