Nutritional labelling for promoting healthier food purchasing and consumption

The primary objective of this review is to assess whether nutritional labelling of foods in comparison to the same foods presented either without a label or with an incomplete label promotes:

  1. healthier food purchasing behaviour from: a) restaurants, b) food shops, c) vending machines; or
  2. healthier food consumption behaviour.

The secondary objective of the review is to explore possible modifiers of the effect of nutritional labelling on purchasing and consumption (described in more detail under 'Types of outcome').

This is a protocol.
