It makes sense that improvements in diet can improve not only physical but mental health as well.
The research showed a positive association between the quantity of fruit and vegetables consumed and people’s self-reported mental well-being.
Specifically, the findings indicate that eating just one extra portion of fruits and vegetables a day could have an equivalent effect on mental well-being as around 8 extra days of walking a month (for at least 10 minutes at a time).
Dr Neel Ocean of the University of Leeds, who authored the study with Dr Peter Howley (University of Leeds) and Dr Jonathan Ensor (University of York), said: “It’s well-established that eating fruit and vegetables can benefit physical health.
“Recently, newer studies have suggested that it may also benefit psychological well-being. Our research builds on previous work in Australia and New Zealand by verifying this relationship using a much bigger UK sample.
“While further work is needed to demonstrate cause and effect, the results are clear: people who do eat more fruit and vegetables report a higher level of mental well-being and life satisfaction than those who eat less.”
Dr Howley said: “There appears to be accumulating evidence for the psychological benefits of fruits and vegetables. Despite this, the data show that the vast majority of people in the UK still consume less than their five-a-day.
