"A vitamin is a substance that makes you ill if you don't eat it"
About this Quote
That inversion does real rhetorical work. It drags the concept back from wishful thinking to measurable biology. “A substance that makes you ill if you don’t eat it” is deliberately unromantic, almost petty in its phrasing, and that’s the point: it’s a scientist’s impatience with vague health talk. It also hints at a broader scientific ethic: define things by testable consequences, not by prestige labels. Vitamins are not “healthy,” full stop; they’re required inputs in tiny doses, and the body keeps score.
Context matters here. Szent-Gyorgyi helped isolate vitamin C and worked in an era when deficiency diseases (scurvy, pellagra, rickets) made nutrition a matter of public health, not lifestyle optimization. The subtext reads like a warning to modern supplement culture: if you’re chasing vitamins as an upgrade, you’ve missed their real narrative - prevention, not transcendence.
