less plastic, please.

Plastic has turned up in human blood, arteries and brains. We report what the research shows, name the companies making the mess, and vet the glass, steel, wood and clay that can replace it, against a standard we publish in full.

It's already inside us.

Three peer-reviewed findings from the last four years. Read the caveats too: finding plastic in a body is not the same as proving it causes harm.

  1. Blood: Plastic particles were measured in the blood of healthy volunteers, at a mean of 1.6 µg per milliliter: the first time plastic in human blood was quantified.

  2. Arteries: Among 257 patients followed for about 34 months, those with micro- and nanoplastics in their artery plaque had 4.5 times the risk of heart attack, stroke or death. The study shows an association, not proof of cause.

    Marfella et al., New England Journal of Medicine, 2024

  3. Brain: Microplastic levels in human brain and liver samples rose significantly between 2016 and 2024, and were higher still in brains of people diagnosed with dementia.

What it means for your health, and what it doesn't

The plastic inside your cans: linings, BPA and what replaced it

Canned pumpkin, cranberry sauce, broth and beans all come in a metal can with a plastic coating inside. What that lining is made of, what moves into the food, and what to do about it this Thanksgiving.

  • Food cans are lined with a thin plastic coating, for decades usually epoxy made from BPA. A 2016 survey by advocacy groups found BPA epoxy linings in 129 of 192 cans, including all 15 cans of broth and gravy.
  • In a 2004 study, most BPA had moved into the food by the end of factory processing, and heating food in its can made no appreciable difference. Salt, oil and high heat raised migration in other lab tests.
  • Polyester, PVC-based and newer bisphenol linings have been found to release their own chemicals, and replacements such as acrylic have barely been studied. 'BPA-free' is not the same as 'tested and safe'.
