It turns out we should follow our parent's advice when we're thinking about becoming parents ourselves, with a study finding eating the traditional 'three-vegies' before pregnancy lowers the risk of a premature birth.
University of Queensland PhD candidate Dereje Gete analysed the diets of nearly 3500 women and found high consumption of carrots, cauliflower, broccoli, pumpkin, cabbage, green beans and potatoes before conception helped women reach full term pregnancy.
"Traditional vegetables are rich in antioxidants or anti-inflammatory nutrients, which have a significant role in reducing the risk of adverse birth outcomes," Mr Gete said.
"Women depend on certain stored nutrients such as calcium and iron before conception, which are critical for placenta and foetus tissue development.
"Starting a healthier diet after the baby has been conceived may be too late, because babies are fully formed by the end of the first trimester," he said.
Professor Gita Mishra said the study suggested dietary intervention and strategies to change behaviour may be helpful when women start thinking about having a baby.
"People born prematurely face a greater risk of metabolic and chronic diseases in adulthood, as well as poor cognitive development and academic performance," Professor Mishra said.
Premature births, which are births before 37 weeks of gestation, are the leading cause of death in Australian children and affect 8.5 per cent of births each year, a figure which is trending upwards.

The research was part of the Australian Longitudinal Study on Women's Health, a large ongoing population-based study of more than 57,000 women investigating the role of socio-demographic, biological, physical, environmental and behavioural factors on health and well-being.
