Technical appendix: Methods for modelling of calorie reduction
This briefing should be read in conjunction with Evidence Briefing 3. It draws on Nesta’s NPM category tax model, focusing specifically on calculating the sugar reduction that could be achieved, and the associated health impacts that could be gained from the salt and sugar reductions. It has been conducted to provide comparable data to the previously published salt and sugar reductions and health impactions from a salt and sugar levy, as proposed in the National Food Strategy.
Recipe for Change: Coalition coordinated by Sustain calling for an industry levy to help make food healthier.
