A new CLOSER research case study illustrates what longitudinal population studies can tell us about the potential effects of long-term consumption of ultra-processed foods on older people’s mental health.
This latest case study on ultra processed foods and depressive symptoms among older adults arrives at a time where there is much attention on the potential negative effects of ultra-processed foods on health.
What are ultra-processed foods?
Ultra-processed foods (UPFs) cover food products that are created through a series of industrial processes, which can cover many everyday items such as most bread and cereals as well as ready meals.
The research
Researchers used data from the Whitehall II study to explore the topic. The research looked at the association between high intakes of UPFs and the recurrence of depressive symptoms in a British population aged between approximately 50-75 years.
The research found that adults who consumed a high amount of ultra-processed foods (UPFs) for a long period of time had a significantly higher chance of subsequently experiencing depressive symptoms.
The findings suggest that dietary interventions can help promote better mental health, such as policies that promote healthier food choices and lower UPF consumption.
