Health Star Rating Evaluation
Overview

The Health Star Rating (HSR) is a voluntary front-of-pack nutrition labelling system that was introduced to New Zealand and Australia in 2014. We will use our unique databases (annually-updated food labelling and composition data and nationally representative household food purchasing data) that span before and after introduction of HSR, to evaluate this policy. Using difference in difference fixed effects models and other natural experiment methods, we will measure the effects of HSR on population diets, through the pathways of: a) industry reformulation; and/or b) consumer food purchases
Aim
