Sustainability and cost of typical and heart-healthy dietary patterns in Australia.

ABSTRACT:

Study objective

The aim was to quantify and compare the environmental and financial impact of two diets: a heart-healthy Australian diet (HAD) and the typical Australian diet (TAD).

Design

The study involved a secondary analysis of two modelled dietary patterns used in a cross-over feeding trial.

Setting

The evaluation focused on two-week (7-day cyclic) meal plans designed to meet the nutritional requirements for a reference 71-year-old male (9000 kJ) for each dietary pattern.

Main outcome measures

The environmental footprint of each dietary pattern was calculated using the Global Warming Potential (GWP*) metric, taking into account single foods, multi-ingredient foods, and mixed dishes. Prices were obtained from a large Australian supermarket.
