How some manufacturers manipulate food star system

The health star ratings of 20,000 foods have been analysed and here’s what was found.

As you read this, health officials are busy finalising the government’s review of the health star rating system on packaged foods.

One of the issues the review is looking at is whether the system, which has been voluntary in Australia and New Zealand since its launch in 2014, should become mandatory.

This is something public health and consumer groups have called for, but the food industry has opposed.

Our new research, which looked at health star ratings of 20,000 packaged foods, shows why mandatory health stars on all packaged food is needed.

We found less than half of all eligible foods carried them, and those that did were skewed towards foods with higher ratings.

Remind me, what is the health star rating?
The health star system rates products from 0.5 to 5.0 stars to help guide consumers toward healthier choices when browsing the supermarket shelves. When comparing similar products, the general idea is the higher the star rating, the healthier the food.

The health star rating lets you compare similar packaged foods to make healthier choices (Australian Government Department of Health).

However, the government’s review is meant to address criticism the food industry has ‘gamed’ the system by exploiting loopholes in scoring criteria to allow some products high in sugar and salt to still score relatively highly.

While much attention has been directed towards closing these loopholes, public health and consumer groups would also like to see mandatory labelling.

Here’s what we did and what we found
We looked at health stars on packaged food in Australia between 2014 and 2019. We used the FoodSwitch database, which contains information about the labelling and nutrition of packaged food.

Every year, FoodSwitch is updated by photographing labels of all packaged foods and beverages in four large supermarkets in metropolitan Sydney. That’s a total of about 20,000 unique products.

For each year in this study, we recorded whether a product was displaying a health star rating and its value.

Where a product was not showing stars on the pack, we calculated how that product would rate using available nutrition information and applying the government’s calculator.

This gave us an idea of what information manufacturers were not yet providing consumers.

We also looked at the manufacturer of each product, and flagged whether they were represented on the committee overseeing implementation of the health stars system.

Voluntary use remains disappointing
We found uptake of food star ratings has increased steadily over the past five years. But only about 41 per cent of eligible products carried one.

Retailers Coles, Woolworths and Aldi labelled their own private label brands, accounting for about 56 per cent of all health star ratings. Despite this leadership, these retailers were not involved in the implementation committee.

However, members of the industry group the Australian Food and Grocery Council — involved in developing health stars and represented on the implementation committee — were responsible for only 29 per cent of total uptake.

Selective use, on healthier products
Perhaps unsurprisingly with voluntary labelling, health stars were more likely to appear on products with higher ratings. More than three-quarters of all stars were on products rated 3.0 or higher.

With a few exceptions, including McCain Foods, Coles and Woolworths, nearly all companies were more likely to show stars on their higher-scoring products.

We found significant differences between the average rating of products displaying the health star rating, and those made by the same manufacturer not showing a health star rating.

For example, Nestlé showed stars on its Uncle Toby’s breakfast cereals where they scored an average 3.9 stars. But the company did not provide the star logo on its confectionery range, which received an average 1.4 stars.

A voluntary system puts profits before health
Our results illustrate the limits of commercial goodwill in applying health stars voluntarily.

Selective use allows the food industry to market its products as healthy but denies consumers the chance to make meaningful comparisons between products.

In particular, the voluntary system limits consumers’ ability to identify and avoid less healthy foods.

With the government review set to be finalised in mid-July, our work supports arguments for an improved health star rating system to be made mandatory to ensure the system works for consumers, not just food companies.

Here’s what needs to happen next
Making health stars mandatory will take time. However, health officials must commit now to a concrete and public plan to proceed down this path by a specific date in the likely event that uptake remains patchy.

Over the same period the health stars system has been operating, Australian manufacturers have implemented new requirements for mandatory country of origin labelling.

If we’re willing to use regulation to provide consumers more information about where their food comes from, we should be doing the same to provide more information about how healthy their food is too.The Conversation

    Of course, they do not want mandatory star ratings. It is much the same as the LNP don't want a federal ICAC. It will show them up for what they are.

    How about a simple system that shows a larger "kangaroo" emblem that includes what "percentage" Australian product. Also an enlarged "number" on drink containers (bottles and cans) that shows the number of "teaspoons" of sugar per bottle/can. We then know what we are consuming, OK!!!

    Unfortunately no product of any type shows how many spoons of sugar, salt or fats.
    The print is small but they do have a list of nutritional values showing how much carbohydrates (all turn into sugar), a separate quantity of sugar, cholestrol, fats, sodium (salt).
    In general I find the star system to be very misleading. Most products they have it on are either high in sugar, fats or salt. Many "health" foods are not healthy.
    Some products that are labelled made from local and imported ingredients is because spices and some herbs cannot be grown in Australia because we don't have suitable climate

    Divide the sugar figure in grams by 4 to get the number of teaspoons of sugar in a product (4g = 1tsp). And you get that figure from the nutritional lable which IS mandatory on all packaged/canned/frozen/boxed foods.

    I do agree that the nutritional label should be in a bigger font as some are very hard to read especially with the type of lighting used in supermarkets (designed to make food look more appetising not as a light source to read by). And the nutritional profil inclusions should also be standardised. Elements such as fibre for example is often missing because it is not mandatory.

    I NEVER read the star system because I simply don't trust it. We live in a country with lots of fresh fruit, vegies, etc. Just don't buy prepackaged.
