Tiny gut “sponge” bacteria found to flush out toxic PFAS “forever chemicals”

Cambridge scientists have spotted gut bacteria that greedily soak up PFAS “forever chemicals,” then ferry them safely out of the body in animal tests, removing up to three-quarters of the toxins within minutes. Their findings hint at probiotic pills that could shield people from PFAS-linked cancers, fertility issues, and heart disease while lawmakers scramble to rein in 4,700 widespread compounds.

    Doesn’t really seem like they’ll get rid of what’s already in the bloodstream and no real mention of safety yet, but it looks promising.

      I wonder if there are other ways pfas might be circulated out of the bloodstream and back into the digestive system to be collected by this microfauna.

      One of the ways oats and oatmeal reduce the amount of cholesterol in your body is by binding to the cholesterol in bile so it’s excreted instead of being re-absorbed. So the cholesterol could already be in the bloodstream, converted into bile, then excretes with the oats once it’s combined. This clearly has multiple essential organs helping the process, but still, a mechanism like this could still make a difference over time.

        There’s some evidence for the same mechanism of action reducing PFAS:

          Even better, those studies are testing dietary fibre generally, not just oats, so anyone eating their daily fruits and vegetables is already getting that benefit.

      Time to start donating blood regularly. Someone else will get plastics sure, but they’ll need the blood for more pressing reasons.

        I wish I was not a needlephobe as there is some indication it can be good for you the same way things that encourage your old cells to die (senolytics) are good.

          Fasting is a good way to achieve that.

          But as far as donating goes, there may be a day you might be the recipient of much needed blood donations.

          Had a lady need 12 bags of blood after almost exsanguinating following a really complicated delivery (both survived). She never gave blood before due to fear of needles, but now is a regular blood donor because of the importance of it. She told me to not wait and just start giving.

        People automatically start bitching about anything ever so slightly restricting harmful corporation’s actions even when they aren’t even involved with the profits (which also shouldn’t matter, but it’s funny that it’s not even their greed, just brainwashed by propaganda they happily repeat & would die for).

            We are comprised of tangled chains of hydrogen, oxygen, carbon, with a sprinkle of various others. Plastic is slightly more complex chains, developed from the dead and entombed carcasses of ancient flora and fauna. That entombment process adjusts, but doesn’t fundamentally alter the chemistry of those chains.

      Regular plasma donation is the most effective treatment. Blood donation works, too, but you can only donate blood every two months, versus plasma donations up to twice a week.

        I know it’s a joke, but that’s almost certainly not going to be the case. Pathogenic bacteria have fundamentally different metabolism and genes.

        What is more likely is either: ecological imbalance or the bacteria only metabolises the harmful chemicals under extreme deprivation of other carbon sources, which is never realistic, so they never do
