If we would only know which power players are behind this documentary and the studies presented 🙂... Nestle, Coca Cola, Kraft Foods, Unilever, the sugar lobby, animal rights organizations ... ? There are only a few «researchers» speaking in the film. For every scientist in that film you could find 3 with the opposite opinion.
Other then that this film does what most « health » propaganda does: It induces fear into people. Fear is an even bigger cause of illness than the food we eat. It is also a great way to maintain power over people.
Any professional and well informed nutritionist knows a vegan diet is a political diet.
