The purpose of government in supplying social goods like food guides is based on two assumptions:
1. governments are in the best position to avoid conflicts; and 
2.governments have the time, capacity and resources to include all the best research that an individual alone could not accomplish.

This whole discussion is absurd from this perspective.  First, it is about self interested special interests lobbying for their interest.  And second, the board is chock-a-block with self help advice without proper sourcing or evidence.  It is no doubt well intentioned.

But the Food Guide is a classic social good that we need and deserve to be produced to the highest standards.
