There are hundreds of chemicals we now know you need to eat or you get horribly sick, thousands of chemicals we now know you can’t or you get horribly sick, and hundreds of products we know perfectly well you shouldn’t eat but do anyways because we like it. (Sorry coca cola. Also sorry milk of opium). The author mentions none of these, implicitly arguing that they are obvious because we worked them out so they don’t count as nutrition science, and then complains that science hasn’t worked out anything about nutrition that wasn’t obvious.
