This is a super easy litmus test.
If you are ever talking about someone in the context of human health and nutrition and they make a recommendation for fluoride-free toothpaste, you can dismiss their perspective on all other subjects relating to human health and nutrition.
If someone wants to improve human health but they're willing to profit off of fluoride-free toothpaste, they're either totally unaware of what they're talking about and are therefore not worth listening to, or they're a scammer and are therefore not worth listening to.
Lead Safe Mama sells a bunch of bullshit through Amazon affiliate links, but the easiest one to see right away as the sign of someone who cares more about their money than your health is fluoride-free toothpaste.
"Lead Safe Mama Says" is not a good reason to do anything except ignore whatever instructions follow.
There is definitely reason to be concerned about the lead concentrations in cassava flour, there are a few products that, if consumed daily, would put you at risk of having higher lead levels than recommended by the FDA.
But Lead Safe Mama doesn't bother with the FDA, the difference between the presence of lead and exposure risk, or the way that lead is actually tracked by people who are looking to prevent heavy metal poisoning.
Lead Safe Mama says "there is no safe level of lead according to the WHO." What the WHO means when they say that is is that there is no known safe level of lead in your bloodstream. What LFM means when she says that is "all lead is scary and coming to turn your children into autism zombies."
Lead Safe Mama was also the one who raised a huge stink about lead in Stanley cups and other thermoses a couple of years ago. There is lead in some of those products - it's present in the solder used to seal things and isn't bioavailable. Lead Safe Mama was also the one who was scaremongering about vintage plates. She tests for lead in paint using dubious techniques then over-states the risk of exposure and possible outcomes from exposure. There was a whole tumblr shitpost that went viral about it.
So this post (descriptions in alt):
Is entirely based on reporting by a lady who believes that childhood lead exposure is being misdiagnosed as autism, and claims that explains the current high rate of autism diagnosis. A lady WHO RECOMMENDS NATURAL CHELATION for autistic children when they are too frail for CHEMICAL FUCKING CHELATION.
There's a similar post by the same blogger circulating about this Consumer Report's survey of lead in cassava flour that says that Bob's Red Mill is showing lead levels that is 2343% higher than the Consumer Reports recommended .5 micrograms per adult per day (that .5 microgram number is itself modeled on California Prop 65 standards).
So that's got to be a ton, right, like a crazy amount of lead, right?
Nope. It's 11.715 micrograms.
That is below the 12.5 microgram per day reference value set by the FDA for people who are pregnant or could become pregnant, but definitely higher than the 3microgram per day value set for children. Probably your child should not consume a cup of cassava flour from Bob's Red Mill per day.
One point I'm making here is that actually Bob's Red Mill and Pamela's are actually probably fine with their CA65 warning labels - there's not an absurd risk of high blood lead levels from eating their cassava products.
The other point I'm making here is get this fucking autism mom and her bullshit bad science and her child chelation recommendations and her fluoride free toothpaste off my dash.
