Such a shocking revelation!!!!  The Agriculture and Food ministry suggesting that if Canada's Food Guide recommends more plant based foods then the likely outcome will be negative for meat and dairy.     Of course that is going to be the outcome. 

There appears to be a lot of people who don't understand how government policy works. When a Department is proposing a new or changed policy, the draft is circulated to other departments for their input and feedback. The usual process is that the other ministries will advocate for the areas they represent.

The fact the Department of Agriculture and Food stated the obvious does not mean there is some conspiracy going on with changing the Canada Food Guide. The headline is also overly sensational even if "secret" is in quotes.  Government departments always provide advice to other government departments as part of their regular activities. Just because all that advice is not made public does not make it secret.  There is nothing to the story.
