Health, Australia (Commonwealth Union) – The Mediterranean diet is renowned for its health benefits and delicious culinary offerings and has ancient origins not merely a modern trend. Its principles can be traced back thousands of years to the eating habits of people living in countries bordering the Mediterranean Sea, such as Greece and Southern Italy.
The Mediterranean region is known for its high concentration of centenarians—people who live to be 100 years old or more. The Mediterranean diet’s association with longevity has sparked interest among researchers studying the factors contributing to a longer and healthier life.
Despite the term “Mediterranean diet,” the eating habits in the region are diverse and vary from country to country. For example, the Greek diet may differ somewhat from the traditional Italian or Spanish diets, showcasing the rich culinary diversity of the region.
A recent analysis conducted by The University of Western Australia reveals that embracing a Mediterranean diet during in vitro fertilization (IVF) treatment could enhance the likelihood of a successful pregnancy. The findings, featured in today’s publication of Reproductive BioMedicine Online, stem from the research efforts of Professor Roger Hart, associated with UWA’s Medical School and Fertility Specialists WA. The study showcases positive impacts on both embryo development and pregnancy outcomes.
Professor Hart emphasized the compelling evidence supporting the superiority of Mediterranean diets over traditional Western dietary patterns. Numerous clinical trials have consistently demonstrated the favorable effects of Mediterranean diets, characterized by high consumption of fruits, vegetables, whole grains, legumes, nuts, and monounsaturated or polyunsaturated oils, coupled with restricted intake of highly processed foods. These dietary choices appear to play a pivotal role in promoting improved outcomes during IVF treatments, offering a promising avenue for individuals seeking to enhance their chances of successful pregnancies.
“These diets are high in B- vitamins, antioxidants, omega-3 poly-unsaturated fatty acids and fibre and are low in saturated fat, sugar and sodium,” explained Professor Hart.
After conducting multiple clinical trials, the research team reached the conclusion that incorporating these regimens during treatment may yield more favorable outcomes compared to Western diets.
The examined supplements included dehydroepiandrosterone (DHEA), melatonin, co-enzyme Q10 (CoQ10), carnitine, selenium, Vitamin D, myo-inositol, Omega-3, Chinese herbs, and various diets (including weight loss strategies).
“With respect to the nine commonly used nutritional supplements, the evidence was found to be inconsistent and not always of good quality,” added Professor Hart.
He further indicated that nutritional supplements were generally not prescribed but purchased online as well as over-the-counter.
“They’re self-medicated and solid data on usage is impossible to determine,” he further added. “Our information is largely anecdotal but it’s quite clear from online IVF discussion forums that they are widely used and of great public interest.”
Omega-3 fatty acids, commonly consumed in combined preparations, have been extensively studied in the context of in vitro fertilization (IVF). According to Professor Hart, these fatty acids may offer benefits in enhancing the likelihood of successful IVF pregnancies and promoting the health of embryos.
In contrast, studies have indicated that carnitine, selenium, Vitamin D, myo-inositol, Chinese herbs, and various diets, including those designed for weight loss, demonstrated low efficacy.
Among the supplements examined, only CoQ-10 antioxidant and DHEA hormonal supplements exhibited positive effects. Additionally, there is some suggestive evidence that melatonin could be advantageous, although further research is needed to determine the appropriate patient group and optimal dosage.
For women embarking on the journey of conception, it is recommended to supplement their diet with folate, also known as vitamin B9. Seeking guidance from a medical professional, such as a general practitioner (GP), is advised to ensure a comprehensive and informed approach to reproductive health, as indicated by researchers of the study.
