If you want to consider an alternative view, have a look at this video put out in support of veganism. It is full of “science” that supports the view of why protein is bad for you, in fact, “The most dangerous Thing In the World“.
If you still believe that cholesterol causes heart-disease then you might buy into the message. If still you believe that “associated with” is actually science, then you might buy into the message.
I think that the video is a great example of why it is so hard to get a consistent message out due to how “science” is manipulated to support a cause. However, you might watch it and decide that you want to live a vegan lifestyle.
