At a Glance What is PLA (and why “plant-based” can be misleading) What happens when PLA is exposed to hot water Why daily tea habits change the risk What current research suggests about PLA particles How to think about safer tea bag choices Tea is one of those daily habits people don’t think twice about. You heat water, drop in a tea bag, and assume it’s clean and straightforward. But like a lot of things today, the material holding that tea matters more than most people real

Key Points Many non-stick pans rely on fluorinated coatings associated with PFAS chemicals PFAS coatings can degrade when exposed to very high cooking temperatures Older non-stick cookware used PFOA, a chemical linked to serious health concerns Modern non-stick coatings often use related fluorinated compounds with similar persistence Scratched or worn coatings can release microscopic particles into food Stainless steel, cast iron, and carbon steel cookware avoid PFAS coatings

At a Glance Sunscreen helps protect the skin from ultraviolet radiation that can damage skin cells and increase long-term cancer risk. When choosing sun protection, most products fall into one of two categories: chemical sunscreen formulas and mineral-based sunscreens. Chemical sunscreen ingredients absorb ultraviolet radiation and convert it into heat within the skin. Mineral sunscreens use zinc oxide or titanium dioxide to reflect and scatter ultraviolet radiation. Several

Key Points Raw milk contains naturally occurring beneficial bacteria and enzymes  that are largely removed during pasteurization. Pasteurization heats milk to reduce bacteria and extend shelf life in large dairy supply chains. Modern milk is often both pasteurized and homogenized , which changes several natural characteristics of milk. Some people report tolerating raw dairy, fermented dairy, or A2 milk better than highly processed milk . Many foods people eat every day — inc

Key Takeaways Pesticides are widely used in agriculture to control insects, weeds, and plant diseases that threaten crop production. Residues from these chemicals can remain on fruits, vegetables, grains, and legumes after harvest. Certain pesticides are designed to disrupt biological systems such as nerve signaling, metabolism, and hormone regulation. Scientific research has linked several pesticides to neurological effects, endocrine disruption, microbiome disruption, and c

Introduction Plastic cutting boards are common in modern kitchens. They are lightweight, inexpensive, and easy to clean. Over time, however, their surfaces change. Every slice, chop, and scrape leaves marks. Those grooves are not just cosmetic. They show that material has been removed from the surface. When a knife repeatedly cuts into plastic, small pieces of that plastic are shaved off. This happens gradually and may not be obvious while cooking, but the visible scoring is

Key Takeaways Most refrigerator filters use activated carbon Carbon filters improve taste and reduce chlorine and some organic compounds Some refrigerator filters reduce lead, but not all PFAS reduction depends on specific certification, not assumptions Flow rate and contact time limit how much a refrigerator filter can remove Certification standards matter more than marketing claims What Refrigerator Water Filters Actually Are Most refrigerator water filters are compact acti

Avoiding seed oils at home is usually straightforward. Cooking with olive oil, avocado oil, coconut oil, butter, or ghee gives you control over ingredients and preparation methods. Packaged snacks are different. Many foods marketed as “healthy,” “organic,” or “natural” still rely on refined oils like soybean, canola, sunflower, or safflower oil. These oils are inexpensive, shelf-stable, and used across modern food manufacturing. If you’re trying to reduce refined seed oils in

At a Glance Mold testing methods measure different things depending on the technique used Air samples reflect a moment in time, while dust samples reflect longer-term accumulation ERMI and HERTSMI scores are based on DNA analysis, not visual inspection A single number rarely tells the full story Visible moisture problems often matter more than laboratory results alone Testing can be helpful in specific situations but is not always necessary Why Mold Testing Feels So Confusing

At a Glance Heat accelerates chemical migration from food packaging into food Fatty and acidic foods increase transfer rates Many food-contact plastics contain plasticizers, stabilizers, and processing additives PFAS-treated packaging and plastic polymers can shed micro- and nanoplastics Exposure is driven by repeated, high-heat contact over time Bioaccumulative compounds can influence endocrine and metabolic systems Why Heat Changes the Equation Food packaging is designed to

At a Glance Mycotoxins are chemical compounds produced by certain molds during growth and storage. Coffee testing measures specific toxins, not “mold” in general. Roasting kills mold organisms but does not reliably eliminate mycotoxins. Third-party testing varies in frequency, scope, and detection limits. Moisture control and storage conditions play a larger role than marketing labels. Coffee is grown in warm, humid regions where mold can develop during harvesting, drying, an

Key Considerations Boiling addresses microbial risk , not chemical exposure Many common contaminants are not altered by heat Evaporation can increase concentration  of dissolved substances Long-term exposure depends on what remains in the water , not how hot it gets Introduction Boiling water is one of the oldest and most widely trusted ways to make water feel safer. For centuries, heat has been used to kill bacteria, viruses, and parasites, especially in situations where san

Key Considerations Air fresheners are a source of ongoing VOC emissions, not a one-time scent event Enclosed spaces amplify exposure through recirculation and accumulation Odor intensity fades faster than chemical presence Children experience higher exposure per body weight in confined environments Introduction Air fresheners are marketed as quick fixes for unpleasant smells. The promise is simple: spray, hang, or plug something in, and the air feels cleaner. What’s rarely di

Water treatment does not produce chemically neutral water. It is a process of tradeoffs. The same methods that make water microbiologically safe also create new compounds during treatment. They are not contaminants that enter water from pollution or infrastructure failure. They are formed during treatment itself, as a result of deliberate decisions made to control pathogens and prevent infectious disease. Disinfection byproducts are a direct result of how water is treated, an

At a Glance Grains and nuts are among the most common dietary sources of mycotoxin exposure worldwide Mycotoxins form primarily due to moisture, storage time, and handling conditions rather than food processing alone Exposure is typically low-level but repeated due to frequent consumption of staple foods Visual inspection and taste are unreliable indicators of contamination Risk varies significantly by food type, origin, and storage practices Prioritizing storage awareness an

Water quality reports, also called Consumer Confidence Reports (CCRs), are designed to show whether a water system meets regulatory limits. They reflect compliance, not how exposure actually happens over time, how often you’re exposed, or how different contaminants may add up. This article explains what a water quality report actually tells you, what it leaves out, and how to interpret the numbers in a way that supports informed, proportionate decisions rather than confusion

Why Non-Toxic Living Feels So Overwhelming If you’ve ever started reading about environmental toxins, household chemicals, or indoor air quality and immediately felt overwhelmed, you’re not alone. This is often where people throw up their hands and say things like: “You only live once.” “Everything causes cancer.” “It is what it is.” These reactions don’t mean people don’t care about their health. More often, they reflect how overwhelming the conversation around toxins has be

When people think about Volatile Organic Compounds (VOCs), they often picture obvious sources like paint or harsh chemical cleaners. While these can contribute to indoor air pollution, many of the most significant VOC sources in homes are far less obvious—and far more persistent. Chemicals that off-gas into indoor air over time  are released from everyday materials, furnishings, and products we rarely think twice about. Because exposure is ongoing and often invisible, these h

Words like natural , clean , fresh , and eco-friendly  appear everywhere—from cleaning products and personal care to food and home goods. These terms are comforting. They suggest safety, health, and responsibility, often making decisions feel easier at a glance. But there’s an important distinction that often gets lost: marketing language is designed to create confidence, not to explain what’s actually inside a product . This doesn’t mean products using these terms are mislea

The word “non-toxic” is everywhere. It appears on food packaging, personal care products, cleaning supplies, building materials, and wellness marketing. The term often lacks clear and  consistent use on labels, which makes it confusing to the consumer. At ZeroToxins, we use “non-toxic” differently than many brands. In our experience, one of the biggest challenges people face isn’t the lack of information - it’s that it’s too much at once. When everything feels like a problem
