CSIRO Diet Survey to Look at Environmental Impact of Poor Eating Practices

Australians have long been encouraged to eat green for a healthy lifestyle, however a new survey hopes to examine the environmental impact of the nation’s diet.CSIRO will use data from the country’s largest diet survey, the Healthy Diet Score, to look at the role food consumption contributes to our environmental footprint, as well as providing people with a score indicating the nutritional quality of their eating habits.

Improving the national diet can achieve both health benefits and environmental benefits, such as minimising harmful greenhouse gases via reducing processing, packaging and transport requirements. CSIRO research has found that reducing overconsumption of kilojoules and eating whole foods at the levels recommended in the National Dietary Guidelines could cut the greenhouse gas contribution of the average diet by 25 per cent.

People across Australia are being asked to participate in the online survey again this year. Last year more than 70,000 people took part in the Healthy Diet Score, providing researchers with a detailed picture of the country’s eating habits. The survey evaluates diet based on food variety, frequency and quantity of the essential food groups, as well as other attributes to calculate greenhouse gas emissions related to food consumption.

This is the first year that the Healthy Diet Score will use survey data to measure the broader environmental impact of poor eating and the findings will be released later this year. The 2016 edition of the Healthy Diet Score also tracks special diets for the first time, such as vegetarian and gluten free, offering tailored advice for people who struggle to meet the Dietary Guidelines.

Professor Manny Noakes, CSIRO Research Director for Nutrition and Health and the co-author of the CSIRO Total Wellbeing Diet, said “the impact of poor eating habits reaches further than just an individual’s waistline. Obesity and poor nutrition habits negatively affects the broader community. This year’s Healthy Diet Score will help us better qualify the environmental footprint from individuals eating habits.”

How do you measure up?

The CSIRO Healthy Diet Score is a free 10-minute online assessment which evaluates diet quality and identifies areas of improvement and gives your diet a score out of 100.

Professor Noakes said, “The online assessment provides Australians with a simple and trusted way of self-assessing the quality of their diet and how they compare to others of the same age, gender, generation, profession, as well as people from the same state and across the country.  The assessment will also allow us to better quantify the impact of how much and what we eat on our environment.
