Dietary patterns, metabolic syndrome, Poly Cystic Ovarian Syndrome and infertility

Background: Dietary patterns are usually associated with metabolic syndrome and insulin resistance. Insulin resistance is also related to infertility. There are some evidence regarding the role of dietary atterns on metabolicsyndrome, worldwide.Objectives: To determine the associations of dietary patterns, metabolic syndrome, PCOS and infertility.Method: In this systematic review we used electronic databases such as MEDLINE and PubMed; EMBASE; Web of Science Proceedings; Clinical Trials.gov and Google scholar up to March 2017 by using MeSH terms and text words fertility , Dietary Pattern , PCOS , metabolic syndrome . We also considered the role of dietary patterns in metabolic syndrome and PCOS.Results: Adherence to a western dietary pattern which is full of refined grain, sugar sweetened beverages and trans fatty acids is related to enhanced risk of metabolic syndrome and polycystic ovary syndrome. Adherence to a healthy patterns such as DASH diet and Mediterranean diet could reduce the risk of metabolic syndrome. Consuming a diverse diet with emphasis on the whole grain diversity as well as fruit and vegetable diversity could be a good choice to prevent metabolic syndrome. Whole diet indices such as healthy eating index, dietary energy density and dietary acid load are also important in this regard. Adherence to healthy dietary patterns is associated with reduced insulin resistance. Insulin resistance is related to infertility.Conclusion: Adherence to healthy dietary patterns, higher dietary diversity score, lower dietary acid load, higher diet quality could be associated with lower risk of metabolic syndrome and insulin resistance. Adherence to a western dietary pattern is usually associated with metabolic syndrome which may be related to infertility.
