Background
2
Burden of diet-related chronic disease1


Account for 60% of deaths worldwide2
Unhealthy diet is a preventable risk factor
 Individuals and
populations should limit1,3:
 Total calories
 Saturated
and trans fat
 Sugar
 Salt

Nutrition Information on Foods


A hierarchy of information
about nutrition.
To help consumers make
food choices that will
enhance health and reduce
risk of chronic disease.

Claims
(e.g. SF, Trans
and CVD)

Objectives of Nutrition Labelling
5
Nutrition Facts table




Enable food choices that prevent and/or manage
chronic disease
Standardize presentation to↓ consumer confusion
Allow comparisons among foods at point of
purchase
Support healthier product reformulations
Government of Canada. The Canada Gazette, Part II. 2003
Is Canada meeting these objectives with
current nutrition labelling regulations?
6


Use of Nutrition Label hampered by:

Numeracy challenges

Confusing use of units: %DV, g, mg,

Serving size use and understanding

↓ nutrition knowledge

Can’t interpret the information

Nutrients to limit/encourage not clear
Product reformulation NOT evaluated

used to set nutritional standards

Classification based on nutritional composition 5,7,8
 Considerations:
 Purpose
and target audience,
 Application of criteria (e.g. by category or across the
board?)
 Which nutrients included (e.g. Nutrients to limit
and/or Nutrients to encourage?)
 Reference amount (per serving or per 100 g?)
 Type of model (e.g. thresholds or algorithms?)
 The scientific basis for used criteria (e.g. nutrition
recommendations, DRIs, “better than” etc)

 Collected
 From


FOP labelling not addressed in the
recent Health Canada consultation
document on Nutrition Labelling,
despite consumers’ desire for
Interpretive Labelling
You could colour-code labels or give letter grades for meeting or exceeding
dietary requirements.”
“Create a universal grading system for consumers to know if a food is a
‘choose most often’ or ‘choose sometimes’ food.

Potential to improve dietary intake and reduce
diet-related chronic disease 1-3
1. Help consumers select healthier foods?
2. Stimulate healthy product development and
reformulation by manufacturers?
