MICROPLASTICS FOUND IN CORONARY BLOOD OF 84% OF SERIOUS HEART ATTACK PATIENTS
A peer-reviewed study published in the European Heart Journal — one of the most respected cardiology journals in the world — has found what scientists are calling a striking association between microplastic exposure and serious cardiac events.
Researchers at Sapienza University of Rome analyzed blood drawn from the coronary arteries of patients experiencing ST-elevation myocardial infarction — the most serious category of heart attack. They found micro- and nanoplastics in the coronary blood of 84% of those patients.
By comparison, microplastics appeared in 40% of patients with chronic coronary disease, and 32% of healthy control subjects — a gradient by severity that researchers described as significant.
The most prevalent type of plastic found? Polyethylene — the same polymer used in billions of plastic containers, bags, and packaging in American homes every year.
Researchers identified the gut and lungs as the two primary suspected entry routes for microplastics into the human body. Patients with detectable microplastics in their blood also showed elevated levels of TNF-α and IL-6 — key markers of systemic inflammation.
The study explicitly called for "policies that reduce environmental plastic contamination."
A companion study published in the New England Journal of Medicine in 2024 (Marfella et al.) went further: researchers found microplastics physically embedded inside carotid artery atherosclerotic plaques — the fatty deposits that cause strokes and heart attacks. Patients with microplastics in their plaques showed significantly higher rates of heart attack, stroke, and death over the study's follow-up period.
The researchers did not establish that microplastics cause heart disease. What they found is an association that scientists say warrants serious attention — and immediate action to reduce exposure where possible.

What's Dissolving In Your Dishwasher Right Now
You know what makes a Cascade ActionPac or a Finish Powerball pod easy to use? You just drop it in and walk away. No measuring. No mess. The pod does everything.
Here's how.
The entire pod — the liquid, the powder, the gels inside — is encased in a thin plastic outer shell. That shell is made of PVA: polyvinyl alcohol. A synthetic water-soluble polymer. It's the "film" that makes a pod a pod.
When you start your dishwasher, that film begins to dissolve. Your machine runs at 120 to 160 degrees Fahrenheit. At those temperatures, the PVA shell breaks down completely, usually within the first minutes of the wash cycle. The soap releases. The pod "works."
And the dissolved PVA? It goes into the wash water.
That same hot water — now containing the dissolved contents of everything that was in and around that pod — is what rinses your plates. Your wine glasses. Your children's bowls. The cutting board you'll use tomorrow morning.
Now read the European Heart Journal study again.
Researchers found microplastics — including synthetic polymers — in the coronary blood of 84% of serious heart attack patients. The gut, they noted, is one of the two primary suspected entry routes for microplastics into the body.
We're not saying your dish pod is causing heart disease. The researchers aren't saying that either. What they're saying is that microplastics are getting inside the human body, the gut is a primary route, and the association with serious cardiac events is significant enough to warrant action.
And every single time you run a conventional dishwasher pod, a plastic film dissolves into the water touching what your family eats off.
Once you know that, you can't un-know it.
Earth Breeze Dishwasher Tablets have zero PVA. No outer film. No coating. No synthetic polymer dissolving into your wash water. Just a clean tablet that cleans your dishes.
And That's Before We Get To The Bleach
Here's something you won't find on most dish pod commercials: approximately 75% of conventional dishwasher detergents contain chlorine bleach — sodium hypochlorite or sodium dichloroisocyanurate.
Cascade. Finish. Most of the store-brand alternatives. Bleach is how they achieve that bright-white, sanitized look.
Then there are the optical brighteners — UV-fluorescent chemicals that coat dish surfaces to make them appear whiter under light. The Environmental Working Group gives many optical brighteners a "D" or "F" rating for environmental concerns, including aquatic toxicity and documented bioaccumulation in water systems.
And the synthetic fragrances. "Fresh scent" and "lemon burst" are marketing words. On an ingredient label, "fragrance" is a single word that can legally represent dozens of undisclosed chemical compounds — some of which appear on the CPSC and EWG concern lists.
Earth Breeze contains:
- ❌ No chlorine bleach
- ❌ No optical brighteners
- ❌ No synthetic fragrances
- ❌ No artificial dyes
- ❌ No SLS
- ❌ No parabens
- ❌ No 1,4-dioxane
- ❌ No ethoxylated alcohols
10 ingredients. That's the whole list.
The PVA story is the lead. But it's not the only reason to look at what's in your dishwasher.
One Switch. Zero PVA.
You can't control the air quality in your city. You can't filter out every microplastic in your tap water. You can't unplastic the oceans.
But you can control what goes into your dishwasher.
That's not nothing. That's one cycle a day, every day, for every person in your household — the dishes you eat off, the cups you drink from, the forks your kids use at dinner. It's a small decision that happens every single day.
The researchers who published in the European Heart Journal called for action. They called for policies to reduce environmental plastic contamination. Policy moves slowly. Your dishwasher detergent choice can change tonight.
One product. One switch. Zero PVA.
Introducing Earth Breeze Dishwasher Tablets
Zero PVA. Zero plastic film. Just clean.
Earth Breeze Dishwasher Tablets are not pods. There's no plastic shell to dissolve. No synthetic polymer film releasing into your wash water. Drop the tablet directly into your dishwasher detergent drawer — that's it.
What's inside:
Just 10 ingredients. Every one of them earns its place.
Three enzymes — not the standard two:
Most dishwasher detergents, including the "eco" alternatives, use two enzymes. Earth Breeze uses three:
Amylase
breaks down starches (pasta residue, cereal, sauces)
Protease
cuts through protein-based soils (egg, meat, dairy)
Cellulase
this is the one most brands leave out. Cellulase is what prevents that cloudy film and white residue that slowly fogs your glasses and makes your dishes look like they weren't washed properly. It's why people give up on eco tablets and go back to Cascade. Earth Breeze kept the cellulase.
Built-in corrosion inhibitor. Dishwashers run hot. Over time, that heat — combined with harsh cleaning agents — etches your glassware, dulling crystal and clouding glass. Earth Breeze's built-in corrosion inhibitor protects your glassware cycle after cycle.
Leaping Bunny certified. No animal testing. Certified by the Coalition for Consumer Information on Cosmetics — the gold standard for cruelty-free verification.
Made in America — with domestic and imported ingredients.
Independent third-party lab tested — in head-to-head testing, Earth Breeze Dishwasher Tablets outperformed the #1 eco tablet on Amazon.
What's NOT inside:
- ❌ PVA (no film, no coating, no plastic dissolving in your wash)
- ❌ Chlorine bleach
- ❌ Ethoxylated alcohols
- ❌ Artificial dyes
- ❌ Synthetic fragrances
- ❌ SLS
- ❌ Parabens
- ❌ 1,4-dioxane
Packaged in plastic-free cardboard. Not a plastic tub. Not a resealable plastic bag. A cardboard box.
10 ingredients. Three enzymes. Zero PVA. Outperforms the competition. Ships to your door in a cardboard box.
That's what you put in your dishwasher instead.

What Customers Are Saying
"I've been thinking about that study for weeks."
Meredith K. — Portland, OR — Verified Buyer
"I saw the European Heart Journal story on a health newsletter I follow and sent it to my husband in the middle of the night. We have three kids and we run the dishwasher twice a day. I started researching dish tablets immediately and found Earth Breeze. Honestly the science on PVA is what sold me — the idea that a plastic film is dissolving into the water rinsing our forks every single night was enough for me to switch immediately. The tablets actually clean as well as Cascade, which I was not expecting. The glasses look cleaner than they have in years — no clouding. We're not going back."
"I'm a nurse. I take ingredient lists seriously."
Tamara B. — Austin, TX — Verified Buyer
"I've been looking for a dish product with a clean ingredient list for years. Most 'eco' brands still use bleach or optical brighteners and just don't tell you. Earth Breeze is 10 ingredients. I can look every single one of them up. When I read about the microplastics study — 84% of heart attack patients — and then learned that regular pods have a PVA plastic shell that dissolves in the wash water, something clicked. I work in healthcare. I can't control everything, but I can control this. Three weeks in, my dishes are genuinely cleaner and my wine glasses look new again. The cellulase enzyme thing is real — I had no idea that's what was causing the cloudiness."
"Switched after reading the SciTechDaily article. No regrets."
Rachel D. — Denver, CO — Verified Buyer
"My husband thought I was overreacting when I said I was switching our dish tablets because of a microplastics study. Then I explained the PVA thing — that the plastic shell literally dissolves in the hot water and that's the water cleaning our dishes — and he went quiet for a second and said 'okay, fine.' Earth Breeze is cheaper than Cascade on subscription, it ships in a cardboard box (no plastic tub to recycle-guilt about), and it actually cleans our cast iron pan residue and the baked-on stuff from our baking sheets. I was skeptical. I'm a convert."
"The cloudiness on my glasses is GONE."
Joanna M. — Chicago, IL — Verified Buyer
"I switched from a 'green' pod brand that I thought was better than Cascade. Still had plastic pods, still had the film, and my glasses had this foggy film that I thought was just hard water. Three cycles with Earth Breeze and that film is gone. I later read that it's a cellulase enzyme that does this — it's in Earth Breeze but not in most eco pods — and it made me realize how little I knew about what was actually in the products I was using. The whole PVA-in-dishwasher-water thing doesn't sit well with me. Glad to be done with it."

Frequently Asked Questions
Yes — and in independent third-party lab testing, Earth Breeze Dishwasher Tablets outperformed the #1 eco tablet on Amazon. The performance difference people notice most is the elimination of cloudy film on glassware — a result of Earth Breeze's cellulase enzyme, which most conventional and eco brands don't include. Cellulase breaks down the cellulose-based residue that builds up over time and fogs dishes. Most customers who switch from Cascade Platinum report their glasses look cleaner within the first few cycles, not worse.
For heavily soiled loads — baked-on food, greasy pans — Earth Breeze's three-enzyme formula (amylase for starches, protease for proteins, cellulase for residue) handles the full spectrum of what a dishwasher load actually contains. Works in hard water too — the citric acid and sodium bicarbonate combination actively descales and counteracts mineral buildup, which is what causes that white haze on glasses in hard water areas.
Earth Breeze Dishwasher Tablets are formulated with: sodium carbonate (cleaning agent), sodium bicarbonate (water softener), citric acid (rinse aid/descaling), sodium silicate (corrosion inhibitor for glassware), amylase (enzyme — breaks down starches), protease (enzyme — breaks down proteins), cellulase (enzyme — removes film and residue), sodium percarbonate (oxygen-based whitening, not chlorine), polyaspartic acid (anti-redeposition agent), and a plant-based surfactant. No chlorine bleach. No dyes. No synthetic fragrance. No PVA.
Most are not. PVA (polyvinyl alcohol) is the outer film/shell that holds most dishwasher pods together — including many that market themselves as "eco-friendly," "plant-based," or "green." Seventh Generation pods, Method pods, and similar brands still use a PVA outer film. The "eco" label typically refers to the product's ingredients or biodegradability claims — not whether it contains a synthetic polymer shell that dissolves in your dishwasher water.
If you want to verify your current pods: flip the package over and look for "polyvinyl alcohol," "PVA," or "film" in the ingredients. Earth Breeze is a tablet — there is no film, no shell, no coating. Just the tablet.
A note on the PVA debate: The cleaning industry (American Cleaning Institute) says PVA fully biodegrades in wastewater treatment and does not form persistent microplastics. Independent researchers at Arizona State University published findings showing PVA does not fully degrade in most US wastewater systems. The science is actively debated. What isn't debated: Earth Breeze has zero PVA. There's nothing to biodegrade because there's no film in the first place.
There are an estimated 85 million dishwasher-owning households in the United States. The majority use pods or tablets. If a fraction of those households switch to a zero-PVA, plastic-free-packaged option, the reduction in synthetic polymer cycling through American kitchens — and American wastewater — is measurable.
But beyond the macro picture: the European Heart Journal researchers called for individual action to reduce plastic contamination. The gut is one of the two primary suspected entry routes for the microplastics found in coronary blood. Your dishwasher runs every day. The choice you make about what goes in it is one of the most repeated exposure-relevant decisions in your household.
One household. One switch. Repeated 365 times a year.
