For some perspective, the original guide was produced to help the Canadian population to stay healthy during war induced restrictions.

The later, and current version of the guide influence institutional kitchens that do not have dedicated nutritionists such as daycares, some schools, clinics, etc.

If I followed by grandma's preferences we'd be eating canned food, salted meat, mincemeat pie, a lot of mayonnaise and cookies (exaggerating of course).
