    So I’m all for substances to be routinely measured for lead concentration. I wouldn’t be surprised if lead and fascism have a link.

    But, because of leaded gasoline and widespread use of lead in other products historically we cannot escape 0 lead.

    I wouldn’t be surprised if you took a plate of food from a randomized selection of restaurants, you would find lead in every meal.

    Lead is dense, and leaded gasoline absolutely fucked our planet. We know the safe level is 0.

    We cannot say that any measurement of non-zero is worse than what we can ultimately control for. We need to be measuring these things over decades, to verify the amount continues to decrease with the ultimate hope of 0 (though, that’s unlikely).

    I don’t dispute her lead findings, but her statement about Hydroxyapatite shows she’s willing to give comment on things she knows nothing about.

    Hydroxyapatite is extracted from cow bone and added because it allegedly helps teeth absorb calcium, though Rubin said she doubts it does.

    Hydroxyapatite is used as an alternative to flouride, as it’s able to attach to the enamal and act as a barrier similar to how flouride does.

    Research has shown it’s less effective than flouride overall (it can’t withstand as low a pH/acidity before dissolving), but it’s not added to increase calcium absorption, like she claims.

      Hydroxyapatite is basically bone without the last calcium ion, which is calcium apatite

      Hydroxyapatite is present in bones and teeth; bone is made primarily of HA crystals interspersed in a collagen matrix—65 to 70% of the mass of bone is HA. Similarly HA is 70 to 80% of the mass of dentin and enamel in teeth.

      I think you may want to reconsider, it might not be used for calcium absorbtion (that’s via preferential binding and transport pathways in the gut lumen), the apatite is absorbed by the collagen matrix for the outer coating, effectively regenerating the tooth.

      Flouride is a stronger, but worse version of this (strengthing apatite without the Ca++ ion), though both together could theoretically be optimal, I don’t know of any studies looking into this, and we should be wary of making such claims barring evidence.

        I’m not suggesting hydroxyapetite is without merit for dental purposes, it absolutely is useful, and I agree combining it with flouride would likely be optimal (I recall reading a study that seemed to suggest HA can actually remineralize deeper into the tooth than flouride can).

        I was just pointing out that the woman in the article didn’t seem to know what hydroxyapetite is actually used for, despite trying to seem like a source of knowledge.

      Tamara Rubin is a grifter with no expertise who bought an XRF gun to use to scan random objects as fodder for her blog where she gets money from affiliate links. Her wikipedia page talks about a few of her financial crimes. I wouldn’t worry anything she puts out.

    I can’t tell from the article if there’s a real problem. None of the levels exceed FDA thresholds, and it sounds bad, but there’s also no definite claim of harm.

      The highest levels detected violated the state of Washington’s limits


      https://tamararubin.com/about/

      Tamara Rubin is an internationally recognized, multiple federal award-winning Lead-poisoning prevention advocate, documentary filmmaker, and mother of four sons (ages 26, 20, 17, and 14). She took on the cause of childhood Lead poisoning and consumer goods safety advocacy after her sons were acutely Lead poisoned by the work of a painting contractor in 2005. Tamara lives in Portland, Oregon with her husband and two youngest sons (who each have permanent disabilities from Lead exposure as infants).

      She does this work specifically because it can cause permanent harm. Her family literally are victims of it.

      Also, as the article notes, Washington State has much stricter standards than the Federal government.

      More on Rubin:

        If her youngest sons with permanent lead exposure injuries were 14 and 17 in 2023, and the lead exposure event took place in 2005, when her older children were young, some of the math isn’t mathing for me.

      When it comes to lead, there is no “safe” level of lead in ones body. I think the reason the FDA has a limit is because we know it’s everywhere, so having a standard limit lower than where the average person may begin to see noticeable side-effects is important. Although, as everyone’s body chemistry varies, what is “safe/tolerable” for one individual may not be for another.

      Lead is also one of those things that from research I have read affects children to the greatest degree while their little brains are growing. In children it can cause things like aggression, learning disabilities, and slow growth and development amongst other things.

      Also this is only one source of lead children (or any of us) may be absorbing, which would make you wonder about a compounding affect when looked at in aggregate. We know it’s in a LOT of chocolate, spices (cinnamon being the current one doing kids in), toys, and environmental things like paint in places like old homes and schools (read a story not long ago about a kid they figured out was being poisoned from lead paint dust on a windowsill at school).

      The max thresholds don’t mean it’s fine if it’s lower, just that at some point it becomes difficult to both detect the presence of things and there’s a limit on how much can be prevented. If we were progressing in time correctly we should be lowering these maximum levels both in the ability of detection and in the beginning sources. Especially in cases like this where either the metals are being added or are part of specific ingredients that would cost more to process and remove the metals.

      And wow, they said Washington State was lower than the FDA, but that’s a magnitude less! Good job, Washington!

      Per the FDA, there is no known safe amount of lead exposure. If it’s in something you want to minimize your exposure to it.

      The article told you. There is NO safe level of lead. The legal limits are not appropriate for health.

      Low level mass lead poisoning makes the world make a lot more sense now.

    Don’t worry, we’ll just cut the FDA funding and stop testing… problem goes away just like that

    I think in 100 years our ancestors will find it barbaric that we scrapped our teeth with metal tools and used abrasives to keep them clean instead of having bioengineered bacteria just keep our mouths clean.

      Probably because the bulk of the products tested were likely kids toothpastes.

      Lead Safe Mama community members nominate products for laboratory testing and then the LSM community uses crowd-funding (including through GoFundMe) to raise the funds to cover the costs related to testing and reporting of these nominated products. This is how the toothpaste and tooth powder products listed in the chart below were chosen for testing, and how the testing and reporting was paid for.
