Revisione del 2015

Lo scopo di queste FAQ è quello di fornire delle risposte semplici ma scientificamente documentate alle più frequenti obiezioni e critiche che vengono rivolte all'alimentazione vegetariana, tutte dovute alla disinformazione sul tema. La lettura attenta di queste risposte mostrerà che le critiche sono frutto di convinzioni e opinioni prive di fondamento scientifico e che tale scelta è non solo priva di pericoli, ma anche ricca di vantaggi per la salute.

La ricca bibliografia da cui sono tratte le risposte è indicata nella sezione References di questa pagina.
