Debate about whether veganism is a healthy diet for humans or a fast track to deficiency has been raging since time immemorial (or at the very least, since the advent of Facebook comment sections).
The controversy is fueled by ardent claims from both sides of the fence: long-term vegans reporting good health (and insisting anyone who struggles must be “doing it wrong”), and ex-vegs recounting their gradual or rapid decline (in some cases, convinced the day will come when “successful” vegans confess it was all a ruse).
Luckily, science is nudging us closer to an understanding of why people respond differently to low- or no-animal-food diets — with a great deal of the answer rooted in genetics and gut health.
