Good afternoon.

Ultra-processed foods now make up nearly half of the average Australian’s diet because the country has “fallen behind international best practice” on nutrition, a co-author of a major new global report says.

The report found Australia, alongside the US and the UK, has some of the highest consumption rates of UPFs, which have become a “central part of dietary patterns for most of the population” and are a “key driver … of multiple diet-related chronic diseases”.

Foods including ready meals, cereals, protein bars, fizzy drinks and fast food are associated with an increased risk of obesity, type 2 diabetes, heart disease and depression.

“There are no taxes on sugar and soft drinks [like] other countries are doing,” said Prof Mark Lawrence, a co-author of the series from Deakin University.

Hughes, speaking on 2GB radio, also accused the party’s conservative faction of using women to do the undermining, singling out Jacinta Nampijinpa Price and Sarah Henderson.
