Aldi is said to stock some of the nation’s most unhealthy foods according to a new study.
Researchers at the George Institute for Global Health and the Global Obesity Centre at Deakin University have found Woolworths’ own-brand range has the highest average health star rating of 3.2 stars, followed by Coles, Aldi and IGA, which got 2.6 stars.
They found A2 Dairy, Sanitarium and Nudie Foods were the healthiest, with an average rating of more than four stars, while the wost were Red Bull, Frucor, Mondelez (which owns Oreo) and Bundaberg Brewed Drinks, which averaged 1.3 stars.
They found Aldi had the highest proportion of discretionary foods on the shelves and its own-brand products were the most “ultra-processed”, relying heavily on sugar, oils, fats, salt, anti-oxidants, stabilisers and preservatives.
“We’re talking about differences in salt, saturated fat and sugar content,” Associate Professor Gary Sacks from Deakin University said. “On average, if you were to buy home brands products from Woolworths, those products are likely to be quite a bit healthier than those from IGA.”

The new report, FoodSwitch: The State of the Food Supply, shows that, between 2017 and 2018, Woolworths maintained its ranking as the healthiest supermarket, while IGA’s ranking slipped from second to fourth.
