You are lucky to be sufficiently informed to eat sensibly; most people are  easily manipulated by industry marketing.

As for the "nanny state" Health Canada is not forcing you to follow their recommendations but simply acting as a countervailing force against industry marketing (or they should be but usually are not)!
