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.
I’ve had a similar experience with other alternatives like Soy curls, which I got to taste good a couple times but strangely could never replicate, and ended up just tasting like adding cereal to me. And Beyond beef, which has an off flavor from the pea protein base.
Quorn seemed to have no off flavor to me or my family, it seemed totally neutral, and they couldn’t tell the difference in tacos, chili, stuffed peppers, etc. I was surprised it wasn’t more popular based on how long its been around.
Maybe there’s a genetic component that’s influencing our flavor perception of it? like how saccharine can taste terrible to people due to genetic differences, limiting its use in soda or candy.
