Brain sand...
Maybe that's why astroman and I frequently think about
tropical destinations, tiki torches, and Hawaiian music? Perhaps we have tropical brain sand.
Thanks for the warning, Rainy.
It was >20 years that I had an MRI for migraines and I learned that my pineal gland was partially calcified. That was without any hydroxyapatite toothpaste or supplement. From that Wikipedia article and other sources I previously read, hydroxyapatite is a naturally-occuring mineral.
When considering that hydroxyapatite crystals are found in breast tumor and pineal gland calcifications, we should be careful about
assuming reverse causality. That is, assuming that using a hydroxyapatite product may cause those things. They may, but I don't think there's conclusive data on the matter.
In a weird way, this discussion reminds me of Vani Hari ("Food Babe") causing a stir with the chain of Subway restaurants by petitioning them to remove azodicarbonamide (a flour bleaching agent and dough conditioner) from their sandwich bread, because that compound was also found in some yoga mats. If following that line of thinking, I should stop drinking water, as that's a component of antifreeze. Azodicarbonamide and water are not the same, of course. My point is more about
making leaps in logic.
All that stated, after first buying nano-hydroxyapatite toothpaste, I ran across a comment on YouTube about
why we may not want to ingest nanoparticles. That led me to articles like the following:
Is Hydroxyapatite Safe? The Muddy Waters of Nano and Microparticleshttps://bubbleandbee.com/blog/is-hydroxyapatite-safe-the-muddy-waters-of-nano-and-microparticlesBased on such reading, I returned my nano-hydroxyapatite toothpaste and mouthwash and ordered the RiseWell NON-nanoparticle hydroxyapatite toothpaste. Is that 100% safe? I can't say for sure. I don't swallow it and I guess I'm hoping that's good enough.
Now, back to the topic of brain sand, I think I'll go make a brain sandcastle.
