Tyson says pink Himalayan salt’s ‘healthier’ reputation is overstated

What was said

"It comes from, Impurities in the pure crystal lattice of the salt molecule, which is sodium chloride. And in this case, the impurity is an iron oxide. Rust. So the diffusion— oh, okay, you want me to call it that? Okay."

Responding to a question about why Himalayan salt is pink, Neil deGrasse Tyson says the colour comes from trace impurities, specifically iron oxide, rather than anything intrinsically different about salt itself. He adds that while it may contain some iron, he believes the nutritional benefit is commonly exaggerated compared with other dietary sources.
