We re all regularly told we should be eating five portions of fruit and vegetables every day to stay healthy.
Now, scientists have revealed two portions of fruit and three portions of vegetables is the optimal combination for a longer life.
US researchers, who looked at data representing nearly 2 million adults worldwide, found this mix was associated with the lowest risk of death.
Eating any more than five portions of fruit and vegetables a day (400g) was also not linked with any additional reduced risk of mortality.
Researchers also found that not all fruits and vegetables offer the benefit, even though current dietary recommendations generally treat them all the same.
