If you are a woman and want to cut out on stress, add 5-7 servings of fruit and vegetables daily to your plate, a new study has showed.

This habit may lead to a 23 per cent reduction in the risk of developing psychological stress.

The findings showed that women who ate 3-4 daily serves of vegetables had an 18 per cent lower risk of stress, and those who ate two daily serves of fruit had a 16 per cent lower risk of stress.

"We found that fruits and vegetables were more protective for women than men, suggesting that women may benefit more from fruit and vegetables," said lead author Binh Nguyen, doctoral student at University of Sydney in Australia.

However, fruit consumption alone had no significant association with a lower incidence of stress and no significant association was found between higher levels of fruit and vegetable intake (greater than 7 daily serves) and a lower incidence of stress.

"This study reveals that moderate daily vegetable intake alone is linked to a lower incidence of psychological stress. Moderate fruit intake alone appears to confer no significant benefit on people's psychological stress," said Melody Ding from the University of Sydney.

Further, the study appearing in the British Medical Journal Open, also noted that for both men and women who ate 3-4 daily serves of vegetables had a 12 per cent lower risk of stress and those who ate 5-7 daily serves of fruit and vegetables had a 14 per cent lower risk of stress.

For the study, the team included more than 60,000 Australians aged 45 years and above and measured participants fruit and vegetable consumption, lifestyle factors and psychological distress.
