I watched this the other day, I'm not sure if what they portray in this documentary is a case to totally quit milk and dairy, but it was very convincing.
The argument was that simple ingesting meat is deadly for us, it causes an immediate immune response in our body that is negative to our health, if you watch it or have already watch it, you'll know what I mean.
Also things like milk just totally disastrous with all the hormones in it, now I'm no way some crazy vegan trying to push a plant based diet (I've literally just had chicken tikka pasta with mayonnaise), BUT...
Perhaps dairy and meat is the reason for a lot of diabetes and cancer, and it's all covered up because of the amount of money these industries make.
A lot of studies by the big companies against diabetes, heart disease in the USA were advertising healthy diets with meat and dairy, it was found that their sponsors giving amounts in the millions were the big pharmas, meat corps and national egg assoc.
I'm not sure what to think, I'd certainly be worried about eating things that damage my health and are the equivalent of "smoking cigarettes".
its nonsense, ignore it
