Key nutrient profiling metrics for reformulation of packaged food in middle-income countries

The overall aim of this PhD is to determine the key metrics of a nutrient profiling system for reformulation of packaged foods in middle-income countries experiencing different stages of nutrition transition. Objectives include: 1. Define the current landscape of nutrient profiling systems applied in middle income countries, considering local nutritional challenges. 2. Assess the evolution of the nutritional quality of commonly consumed packaged foods in middle income countries over the past five years. 3. Test and compare the performance of different nutrient profiling systems in detecting nutrient density of packaged food in middle-income countries. 4. Determine the theoretical impact of meeting selected nutrient profiling standards on diet quality and chronic disease risk factors in a case study.
