I spent 9 years as an environmental toxicologist.
Last year, I found microplastics in human blood samples.
Not some of them. 80% of them.
Here's what they don't want you to panic about (but you should know):
Most people don't lose interviews because they're unqualified.
They lose because they blank.
The answer is sitting right there in their head. They just can't find it in 6 seconds while someone stares at them on Zoom.
So I built the fix.
It's called Cornerman.

No bot joins the call. No notification. No trace on the other side.
You just quietly look like the sharpest version of yourself.

10/ You do not need to do this all at once. Pick one category this week, replace as items wear out, and prioritize heat contact points first. Your body clears microplastics slowly, so every reduction compounds. I will cover filtration next Wednesday.
9/ Cling wrap and plastic freezer bags. PVC and LDPE leach plasticizers directly into fatty foods. Beeswax wraps, silicone stretch lids, and glass containers handle most of what cling wrap does, and reusable silicone bags replace the rest.
8/ Plastic water bottles and pitchers. A 2024 study found bottled water contains around 240,000 plastic particles per liter, most of them nanoplastics small enough to cross cell membranes. Use glass or stainless with a quality home filter.
7/ Tea bags. A McGill study found a single plastic tea bag releases 11 billion microplastics and 3 billion nanoplastics into your cup at brewing temperature. Switch to loose leaf with a stainless steel infuser. This one still shocks me.
6/ Plastic utensils, spatulas, and ladles. High heat plus plastic equals melted polymer in your food. Wood, bamboo, and stainless steel tools last decades and do not degrade into your cooking. Keep one silicone spatula if you must, food-grade only.
5/ Food storage containers. Heating food in plastic, even BPA-free plastic, leaches phthalates and bisphenol replacements that act as endocrine disruptors. Glass with silicone or bamboo lids is the gold standard. Never microwave plastic.
4/ Plastic kettles and coffee makers. Boiling water in plastic releases trillions of nanoplastic particles per liter. Swap to a stainless steel kettle and a French press or metal pour-over. One of the highest-impact changes you can make.
3/ Nonstick pans. Worn Teflon can release millions of particles per use, especially above 500F. Replace scratched nonstick with stainless steel, cast iron, or ceramic. A single damaged pan can shed 9,000 particles in 30 seconds of cooking.
2/ Start with your cutting board. Plastic boards shed an estimated 50 grams of microplastics per person per year according to a 2023 Environmental Science and Technology study. Swap to end-grain wood or stainless steel. Wood is naturally antimicrobial.
1/ Your kitchen is likely the biggest source of your daily microplastic exposure. After years studying plastic contamination, most people have no idea how much they ingest at every meal. Here is a practical audit of what to swap first.
You eat a credit card every week.
5 grams of plastic. The WWF estimate, repeated until it became background noise.
Today I broke that number apart. Where it actually comes from might change what you do tomorrow morning.
As a former toxicologist, here is what most people miss: not all exposure routes are equal in volume or in controllability.
Some you can shut down this week. Others require systemic change. Knowing the difference is half the battle.
