The study found that those who ate around eight portions of fruit and vegetables a day had an average score that was one point higher than people who did not eat any.
Although it is not known exactly how fruit and vegetables improve wellbeing, they contain chemicals known as antioxidants, which are thought to reduce stress levels.
Recently studies have found that children who eat more fruit and vegetables are less at risk of depression in later life.
Andrew Oswald, of the Warwick University’s Department of Economics, which conducted the research, said: “This study has shown surprising results. We know that fruit and vegetables carry a lot of antioxidants and those protect us against attacks on the body.”
“But how that works through into our minds and emotions, researchers have no idea.”
