lately i did a lot of research about what kind of food best supports fertility and egg quality in women over 35. i would like to share with you what i found out.
in short, there exist three major nutritional approaches:
1. fertility diet as published by the harvard resarchers some years ago (great, but with a limitation that original data come from participants who reported infertility due to ovulatory issues)
2. modified paleo approach (paleo diet with extra carbs),
my hint is, that it could work well in terms of improving egg quality, especially by women with unexplained infertility issues, but for the moment there is no systematic science behind it
3. mediterranean diet. this approach has a solid scientific background.
below is the essence of what i found in various medical journals and below there are a few links you can folow further. should you have more/better references, it would be great if you would join in and let other women know.
there is a proven record of benefits of all kinds.
one study (published in Fertility and Sterility in 2010), found that the mediterranean dietary pattern, when applied six months before conception, significantly increased the chance of pregnancy in 166 dutch couples undergoing IVF treatments.
the couples were asked to answer questions related to their nutrition and lifestyle; on analysis, it turned out that a high intake of vegetable oils, vegetables, fish, legumes, and a low intake of snacks during preconception times, positively correlated with their blood folate and B6, and increased the probability of a couple conceiving a baby.
the benefits of a mediterranean diet were confirmed in a spanish study from 2012, which looked at the cases of 485 women who reported difficulties in getting pregnant, and concluded that adherence to the mediterranean dietary pattern enhanced their pregnancy rates.
the mechanism behind the mediterranean diet is still unknown (antioxidants? olive oil? revestratol? mixture of all factors?)
