A Mediterranean diet is well-known for its multiple health benefits, and now new research has indicated that abiding by the diet - which is high in healthy fats and low in red and processed meat - could help people overcome infertility issues.
Researchers from Monash University, the University of the Sunshine Coast, and the University of South Australia found the diet can improve fertility, assisted reproductive technology (ART) success, and sperm quality in men. In particular, they discovered the anti-inflammatory properties of the diet can improve a couple's chance of conception.
"Research shows inflammation can affect fertility for both men and women, affecting sperm quality, menstrual cycles, and implantation. So, in this study we wanted to see how a diet that reduces inflammation - such as the Mediterranean diet - might improve fertility outcomes," said University of South Australia researcher Dr Evangeline Mantzioris.
"Encouragingly, we found consistent evidence that by adhering to an anti-inflammatory diet - one that includes lots of polyunsaturated or 'healthy' fats, flavonoids (such as leafy green vegetables), and a limited amount of red and processed meat - we can improve fertility."
Plant-based foods, such as whole grains, vegetables, legumes, fruits, nuts, seeds, herbs and spices, form the basis of the Mediterranean diet alongside fish, seafood and extra virgin olive oil. Poultry, eggs and dairy should only be consumed once or twice a week, while red and processed meat should be eaten sparingly.
Monash University researcher Simon Alesi described adopting the diet as a "non-intrusive and affordable strategy" for those who want to start a family.
"The Mediterranean diet is consistently ranked among the healthiest diets in the world. But knowing that it may also boost your chances of conceiving and having a baby is extremely promising," Alesi said.
"Of course, more research needs to be done, but at the very least, shifting to a Mediterranean diet will not only improve your overall health, but also your chances of conceiving."
The review was published in the journal Nutrients.
