Health Benefits of Improving the Food Supply

  • Poor diet major contributor to chronic

disease worldwide

  • Current food supply has excess levels
  • f total fat, saturated fat, sugar and

salt in large serves of energy-dense foods

  • Driving epidemics of obesity, high

blood pressure, diabetes and dyslipidaemia, leading to ↑ heart attacks, stroke and cancer

“Even small changes in key constituents of the food supply have the potential to produce enormous health gains”

Changes to Australian food labelling – Health Star Rating System

The HSR system was developed through a collaborative process involving public health and consumer organisations, industry and government representatives. On June 27 2014 the government agreed that the HSR system should be implemented voluntarily over the next 5 years with a review of the progress of implementation after 2 years.

The real power behind FoodSwitch: crowd-sourcing of data

  • Originally FoodSwitch Australia was launched

with ~17,000 products (SKUs)

  • When products do not appear in the database,

users are asked to help by taking 3 photographs – the front of the product, the nutrition information and the ingredients list – and send them to us.

  • In this way the database can be constantly

updated and new products entered.

  • 26,000 photos sent in by FoodSwitch users in

the first 2 days, and a minimum of 200 photos are sent in every day currently

  • - Database now includes

>80,000 products

  • How do we know whether there

have been actual reductions in adverse nutrient levels in foods?

  • How do we know whether this

has translated into healthier food purchases? But what does this add up to?

Do food labels influence food purchases?

  • Food Label Trial

44

  • Randomised trial with 2000

participants

  • The aim is to find out which type of

label is best at helping people make healthier food and drink choices

  • Participants scan items they

purchase and send in till receipts form grocery shops

  • Results will evaluate whether

different label formats influenced foods purchased

Participants are randomised to one of 5 trial arms
