A healthy diet should include 10 portions of fruit and vegetables a day, doubling the five-a-day official advice, say British health experts.
The research, which involved a 12-year study, also found that vegetables were four times healthier than fruit.
The study, by University College London, found that eating large quantities of fruit and vegetables significantly lowered the risk of premature death. People who ate at least seven portions of fruit and vegetables each day were 42 per cent less likely to die from any cause over the course of the study.
The researchers also discovered that canned and frozen fruit increased the risk of dying by 17 per cent, and fruit juice was found to have no significant benefit.
