Consumption of ultra processed food and mental wellbeing outcomes
October 2, 2023
There has been increasing attention on ultra-processed food (UPF) as the cause various of diseases, particularly in countries such as the United States and United Kingdom, where the majority of calories consumed today come from UPF.
While much of the focus has been on obesity, diabetes, and more recently, heart disease, the mind too is not exempt from its effects. Studies showing a link between UPF consumption and depression are growing. This includes a recent study that demonstrates an improvement of depression symptoms, even with just three weeks of diet change in those who regularly consume a diet of UPF placing UPF consumption as a core cause.
But just how far reaching are the effects of UPF on mental health? Here we look at the self-reported frequency of UPF consumption and its relationship to the full breadth of mental health symptoms, and aggregate mental wellbeing, in a global sample of almost 300,000 people.
- Mental wellbeing decreases sharply with more frequent UPF consumption. Those who consume UPF several times a day are three times more likely to have serious mental health struggles compared to those who rarely or never do.
- While younger adults consume UPF more frequently, UPF consumption has a similar impact on all age groups.
- The decline in mental wellbeing with increased frequency of UPF consumption cannot be attributed to indirect effects of exercise frequency or income.
- Higher frequency of UPF consumption impacts all dimensions of mental function from Adaptability & resilience to Cognition.
- Depression symptoms and problems with cognitive and emotional control dominate with higher frequency of UPF consumption.
- Among 26 countries compared, respondents in the Philippines, United States and United Kingdom reported the highest consumption of UPF, while those in Egypt, Morocco and Venezuela reported the lowest.
