A recent Australian review of 45 meta-analyses involving nearly 10 million participants highlights the significant health risks associated with ultraprocessed foods. Senior author Wolfgang Marx from Deakin University reports that higher consumption correlates with negative health outcomes for over 70 per cent of the assessed conditions. An increase of just one serving daily, equating to approximately 10 per cent more, can elevate risks.
The findings indicate a startling 50 per cent higher risk of cardiovascular-related deaths and notable increases in mental health disorders, along with up to 53 per cent higher risk of anxiety and a 20 per cent increased likelihood of premature death. While there is strong evidence connecting ultraprocessed foods to obesity and type 2 diabetes, concerns persist regarding their precise impact on anxiety and depression.
Ultraprocessed foods, rich in sugars and unhealthy fats, contribute to issues like weight gain and hypertension. Despite the pressing need for further research—especially concerning cancer associations—experts emphasise the urgency of addressing the rising prevalence of these foods, which dominate diets in Australia and elsewhere.
To mitigate these risks, experts recommend opting for fresh, minimally processed foods, cooking at home, and scrutinising product labels. Considerations for regulatory measures, such as clearer labeling and advertising restrictions, are also encouraged to promote healthier dietary choices.
