This is essentially a nutrition bible for anyone, not just vegans, which answers every question one might possibly have about what to eat and why. I haven’t read it cover to cover in that I read all chapters but for the ones that really don’t apply to me at all at this moment in time (what to eat when pregnant or as a child). It is fairly dry reading overall and goes over studies showing the benefits of this or that food, its effects on the body according to scientific trials, how many micrograms of what vitamin is necessary to stay in good health, that kind of thing. So it’s not to read for entertainment purposes, as such, but more a resource to dip in and out of as necessary or when questions arise. I initially thought the dryness (the boredom-inducing dryness, some might say) was inevitable, but since then I have read the superb How Not To Die by the excellent Dr Michael Greger which does not aim at doing the same thing exactly, but presents nutrition in a much more entertaining, exciting light.
Still, Becoming Vegan: The Complete Reference to Plant-Based Nutrition is, as its title affirms, a reference and one I intend to check up regularly.
