Health Canada should require an equivalent to the "plain packaging" tobacco requirement by having three labels that must take up maybe 30% of a food's packaging. The three labels are:
"Natural food" for those products that are found in nature and have little or no additives
"Processed food" for those foods that go through a processing step, other than plain cooking, and may contain added sugars, preservatives, etc.
"Candy" for those foods that contain little nutritional value

Many people will be surprised by the number of foods that fall into the last category.
