With its focus on fruits, vegetables and beans, the Mediterranean diet has long been hailed for its multiple health benefits.

Now research shows it may help overcome infertility, making it a simple strategy for couples trying to conceive.

The Mediterranean diet can improve fertility, the success of assisted reproductive technology, and sperm quality in men, a review by Australian researchers found.

It is believed the diet – which has also been found to protect against conditions linked to inflammation, such as cardiovascular disease and type 2 diabetes – can boost fertility by reducing inflammation.

The Mediterranean diet is primarily plant-based and includes whole grains, extra virgin olive oil, fruits, vegetables, beans and legumes, nuts, herbs and spices

The study, by scientists at Monash University, the University of the Sunshine Coast and the University of South Australia, reviewed research onhow diet can affect conception.

Dr Evangeline Mantzioris, of the University of South Australia, said past research showed inflammation can affect sperm quality, menstrual cycles and implantation.

She said: ‘Encouragingly, we found consistent evidence that by adhering to an anti-inflammatory diet – one that includes lots of polyunsaturated or “healthy” fats, flavonoids (found in leafy green vegetables), and a limited amount of red and processed meat – we can improve fertility.’ The Mediterranean diet is primarily plant-based and includes whole grains, extra virgin olive oil, fruits, vegetables, beans and legumes, nuts, herbs and spices.

Dairy products and lean protein sources such as chicken or eggs are eaten in only small amounts.

Experts believe antioxidants in fruit and vegetables improve the quality of a woman’s eggs and also protect the womb. Monash researcher Simon Alesi said the diet could be ‘a gamechanger’ for couples hoping to start a family.

He said: ‘Modifying your diet is a non-intrusive and affordable strategy that could potentially improve infertility. 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 findings were published in the journal Nutrients.
