Recycled plastic is often presented as the more sustainable choice. But from a chemical-safety perspective, the picture can be more complicated.

In this episode of Practical Nontoxic Living™, I look at research showing that recycled plastics can contain a complex mixture of chemicals from their original products, additives, contamination during use, and the recycling process itself.

That raises an interesting question: Can something be better for reducing plastic waste while still creating concerns about what chemicals remain in the finished material?

In this episode:

• Why recycled plastic isn't chemically identical to virgin plastic

• How additives and contaminants can carry over through recycling

• Why researchers have found substances of concern in some recycled plastics

• The difference between an environmental benefit and a chemical-safety benefit

• Where I'm more cautious about recycled plastic—especially for food contact and frequently handled products

• Materials I often consider instead when a practical alternative exists

Recycling remains important for addressing plastic waste. But "recycled" doesn't automatically mean "safer," just as "eco-friendly" doesn't tell us everything we need to know about a product.

For me, this is another example of why Practical Nontoxic Living™ asks a broader question than Is this green?

It asks: What are the tradeoffs—and what's the wisest choice for this particular use?

• Trying to reduce toxic exposures at home can become overwhelming very quickly. There are too many chemicals, products, materials, and conflicting recommendations to research them all individually.

  That's why I developed the Household Repeat Offenders™ framework.

  First introduced in my book A to Z of D-Toxing, Household Repeat Offenders™ are recurring categories, materials, treatments, and product characteristics that repeatedly show up as potential sources of chemical, heavy-metal, EMF, or other environmental exposures.

  Instead of asking Is this particular product safe? hundreds of times, the framework helps you recognize patterns—and know which questions to ask before you buy, use, or replace something.

  In this episode:

  • The six Household Repeat Offenders™ I prioritize in the home

  • Why recognizing patterns can be more useful than memorizing individual chemicals

  • How the framework can simplify decisions about what you buy, own, and do

  • Why you don't need to replace everything at once

  • How I use Love Test Detox Stickers™ to make decisions more intentional

  • How Household Repeat Offenders™ became central to the 40-Day Home Detox™, Phase One of the Ultimate Home Detox™

  The goal isn't to identify every possible exposure or create a perfectly "nontoxic" home.

  It's to understand enough that the next decision becomes easier than the last.

  That's one of the central ideas behind Practical Nontoxic Living™: learn the patterns, prioritize what matters, and make the wisest choices you reasonably can in the context of a real life.

Plastic straws are a small part of our overall exposure picture—but they're also one of the easiest things to reconsider.

In this episode of Practical Nontoxic Living™, I look at what plastic straws are made from, what researchers know about chemicals and microplastics associated with plastics, and the environmental consequences of using something for a few minutes that can persist far longer.

We also look at the alternatives—because "plastic-free" doesn't automatically mean better in every way.

In this episode:

• Why I generally prefer to avoid single-use plastic straws when I don't need them

• What we know—and don't know—about chemical migration and microplastics from food-contact plastics

• Why a straw is only one small piece of our overall plastic exposure

• The environmental impact of single-use straws and other disposable plastics

• How glass, stainless steel, silicone, paper, and plant-based alternatives compare

• Why reusable options can make more sense when they're practical for your life

I don't think plastic straws deserve fear. I think they're a good example of a broader Practical Nontoxic Living™ principle: when an exposure is easy to avoid and the alternative works just as well, the simpler choice may be worth making.

Your blender probably isn't the biggest source of plastic exposure in your kitchen—but it is something you may use frequently, sometimes with hot, acidic, or abrasive foods.

In this episode of Practical Nontoxic Living™, I look at blender materials and what may be worth considering when choosing or replacing one.

Rather than assuming every plastic blender jar is unsafe, I focus on a more practical question: When does it make sense to choose glass, stainless steel, or less plastic food contact?

In this episode:

• Why I pay attention to the materials that come into repeated contact with food

• What heat, wear, and abrasion can mean for some plastic food-contact surfaces

• Why microplastic shedding from kitchen products is receiving increasing research attention

• The difference between plastic composition, chemical additives, and microplastic particles

• What I look for in a blender when choosing among plastic, glass, and stainless-steel options

• Why replacing a perfectly functional appliance may not always be the wisest first step

The goal isn't to assume that every smoothie made in plastic is contaminated. It's to understand where repeated food contact may matter—and make a more informed choice when you're already buying or replacing an appliance.

That's Practical Nontoxic Living™ for me: reduce unnecessary exposures without turning every kitchen tool into a source of fear.

Choosing food containers for kids sounds simple—until you start comparing plastic, silicone, stainless steel, glass, coatings, lids, seals, durability, and whether your child will actually use any of it.

In this episode of Practical Nontoxic Living™, I walk through the materials and practical tradeoffs I consider when choosing lunchboxes, snack containers, and reusable food storage for children.

Rather than assuming every plastic container is harmful, I focus on a more useful question: Which materials make the most sense for repeated food contact—and for the reality of school lunches?

In this episode:

• Why I pay attention to materials that repeatedly come into contact with food

• What to consider about plastics, especially with heat, wear, and repeated use

• How stainless steel, glass, silicone, and other materials compare

• Six things I look for when choosing food containers for kids

• How to balance lower-exposure materials with durability, weight, leaks, cleaning, and convenience

• Three additional ways to reduce unnecessary exposures in packed lunches

You don't need a perfectly plastic-free lunchbox to make a thoughtful choice.

For me, the goal is to prioritize the places where food has frequent contact with a material, choose simpler options when they work well, and make sure the solution is practical enough that your child will actually use it.

Can radiofrequency radiation from cell phones affect the blood-brain barrier—and what might that mean for brain health?

In this episode of Practical Nontoxic Living™, I revisit a question raised by epidemiologist Dr. Devra Davis, founder of Environmental Health Trust: whether wireless radiation may influence the blood-brain barrier, the protective system that helps regulate what moves from the bloodstream into brain tissue.

Some experimental research has explored this possibility, but the evidence is not settled—especially when it comes to everyday human exposures and long-term health outcomes.

We also consider this question alongside emerging research showing that microplastics and other environmental contaminants can reach the human brain. Importantly, we do not know that cell phone exposure is responsible for allowing those particles into brain tissue.

In this episode:

• What the blood-brain barrier does and why researchers study it

• Research examining whether radiofrequency radiation can affect its permeability

• Why laboratory findings don't automatically tell us what happens during ordinary cell phone use

• What scientists are learning about microplastics and other environmental contaminants in the brain

• Why we should be careful not to assume that one finding explains another

• Three simple ways to reduce unnecessary cell phone exposure without giving up your devices

The science here contains real uncertainty. For me, the useful response isn't to assume that cell phones are "weakening the brain"—or to dismiss every concern because all the answers aren't settled.

It's to understand what is known, what remains debated, and where low-cost precautions may be reasonable.

A 2025 study found microplastics and nanoplastics in human brain tissue—and reported that concentrations in samples collected in 2024 were about 50% higher than in samples from 2016.

That caught my attention.

Researchers also found substantially higher concentrations in brain samples from people who had been diagnosed with dementia. But this is an important distinction: the study did not show that microplastics cause dementia. We don't yet know whether the particles contribute to neurological disease, whether changes associated with disease affect their accumulation or clearance, or some combination of factors.

In this episode of Practical Nontoxic Living™, I unpack what the study actually found, what it didn't establish, and what I think is reasonable to do while the science continues to develop.

In this episode:

• What researchers found when they measured micro- and nanoplastics in human brain, liver, and kidney tissue

• Why the approximately 50% increase between 2016 and 2024 deserves attention

• What the higher levels found in brains from people with dementia do—and do not—tell us

• What scientists still don't know about how microplastics enter, accumulate in, or leave the human brain

• Practical ways to reduce everyday microplastic exposure without trying to eliminate plastic from your life

• Why I focus on reducing recurring exposures rather than searching for an unproven way to "detox" microplastics from the body

This is the kind of research that can easily become frightening once it reaches a headline. I think the more useful response is to separate what we know, what we suspect, and what we don't yet understand—and then look for practical changes that make sense even in the presence of uncertainty.

What if something as ordinary as reaching for the salt could remind you to pay attention?

In this short episode of Practical Nontoxic Living™, I share how I began thinking about salt as more than an ingredient—as a small mindfulness cue embedded in something I already do every day.

Salt also became a useful example of how seemingly simple products can raise larger questions about what we consume, including microplastics, heavy metals, packaging, and the materials we bring into our kitchens.

In this episode:

• How an everyday object can become a prompt to return to the present moment

• Why I started looking more closely at the salt my family uses

• What questions about microplastics and heavy metals made me reconsider some salt choices

• How one purchasing decision can lead us to notice other sources of plastic and unnecessary exposure

• Why Practical Nontoxic Living™ can be as much about awareness as avoidance

I don't want every meal to become another health project.

What interests me more is how ordinary moments can help us notice what we're doing almost automatically—and give us a chance to choose with a little more intention.

Sometimes the practice is that small: notice, understand, choose—and return to your life.

I spent roughly 120 hours researching something most of us rarely think twice about: salt.

What began as a simple question—Which salt should I buy?—turned into a much bigger investigation of independent laboratory testing for lead, arsenic, cadmium, mercury, and microplastics.

In this episode of Practical Nontoxic Living™, I share what I found, which results actually changed what I buy for my own family, and how I think about the significance of contaminants in something we consume in small amounts but repeatedly over many years.

In this episode:

• What independent testing found in some popular salts

• Why heavy metals such as lead, arsenic, and cadmium deserve attention even at relatively low levels

• Why children can be particularly important to consider when thinking about lead exposure

• What "non-detect" does—and doesn't—mean in laboratory testing

• How microplastic contamination varies among salts and why the evidence is still evolving

• The salt I ultimately chose for everyday use based on the testing I reviewed

• How I decide when a small exposure is worth reducing—and when the difference probably isn't worth disrupting real life

After all that research, my takeaway wasn't that salt is something to fear.

It was that this is exactly the kind of decision Practical Nontoxic Living™ can simplify: if two products do the same job, cost roughly the same, and one has substantially lower measured levels of contaminants, why not choose the lower-exposure option?

For me, the goal isn't purity. It's making the wiser choice when the information is available and the tradeoff is small.

Microplastics have been detected in salt from around the world—including sea salt, rock salt, and other varieties.

But how much does that matter, and can the salt we choose meaningfully reduce our exposure?

In this episode of Practical Nontoxic Living™, I look at what researchers have found about microplastics in salt, how they may get there, and why contamination levels can vary substantially among products and sources.

In this episode:

• How microplastics can end up in the salt we eat

• What studies have found when testing different types and brands of salt

• Why sea salt isn't necessarily the only salt worth paying attention to

• What scientists know—and still don't know—about the health effects of ingesting microplastics

• Why "microplastic-free" can be difficult to establish

• How I think about choosing a lower-exposure salt without turning a small dietary ingredient into something to fear

Salt probably isn't the largest source of microplastics in most people's lives. But it's something many of us consume repeatedly for decades.

That makes it a useful Practical Nontoxic Living™ question: If a product we buy anyway has a lower-contamination option with little sacrifice in cost, taste, or convenience, is it worth choosing?

For me, often the answer is yes.
