Avocado diet could triple the chance of success for couples undergoing IVF, claim research by Harvard School of Public Health. Foods containing dressing salads with olive oil and which is consumed as part of the Mediterranean diet could help women who are trying to have a baby through IVF treatment.
Monounsaturated fat, which is found in olive oil, sunflower oil, nuts and seeds, is considered better than any other kind of dietary fat for expecting mothers. Women who consumed the highest amount of monounsaturated fat were more than three and half times likely to have a baby after IVF compared to those who consumed the lowest amounts.
A team led by Prof Jorge Chavarro from Harvard School of Public Health, carried out a small study involving nearly one hundred and fifty women those having IVF treatment at Massachusetts General Hospital Fertility Centre. Their consumption of different dietary fats was recorded and results of fertility treatment were compared between the highest and lowest third of consumption in each group.
They found that women who consumed the highest levels of all types of fat had fewer good eggs available for use in IVF. The connection was driven by the intake of saturated fat, on the other hand high levels of polyunsaturated fat intake produced inferior quality of embryos.
Higher consumption of monounsaturated fat was associated with three and half times higher live birth rate in comparison to the lowest intake. Lead researcher Prof Chavarro, explained the best kinds of food to eat are avocados, which have a lot of monounsaturated fat and low levels of other sorts of fat, and olive oil.
He added the study was small but the findings merited further investigation. While these results are interesting, this is the first time dietary fats have been linked to treatment outcome in IVF. Higher levels of monounsaturated fat were linked to higher live birth rates, which ultimately people are looking for.
Different types of fat are known to have different effects on biological processes which may influence the outcome of assisted reproduction. However, it is not clear at this moment which biological mechanisms underlie the associations that they found. The study was presented at the European Society of Human Reproduction and Embryology in Istanbul.
