The literature on the relationship between diet and human fertility has greatly expanded
\nover the last decade, resulting in the identification of a few clear patterns. Intake of
\nsupplemental folic acid, particularly at doses higher than those recommended for the
\nprevention of neural tube defects, has been consistently related to lower frequency of
\ninfertility, lower risk of pregnancy loss, and greater success in infertility treatment. On the
\nother hand and despite promising evidence from animal models, vitamin D does not
\nappear to exert an important role in human fertility in the absence of deficiency. Antioxidant
\nsupplementation does not appear to offer any benefits to women undergoing
\ninfertility treatment, but it appears to be beneficial when it is the male partner who is
\nsupplemented. However, the available evidence does not allow discerning which specific
\nantioxidants, or at which doses, are responsible for this benefit. Long-chain omega-3
\nfatty acids appear to improve female fertility, although it remains unclear to what extent
\ncontamination of shared food sources, such as fish with high levels of environmental
\ntoxicants, can dampen this benefit. Lastly, adherence to healthy diets favoring seafood,
\npoultry, whole grains, fruits, and vegetables are related to better fertility in women and
\nbetter semen quality in men. The cumulative evidence has also piled against popular
\nhypotheses. Dairy and soy, once proposed as reproductive toxicants, have not been
\nconsistently related to poor fertility. In fact, soy and soy supplements appear to exert a
\nbeneficial effect among women undergoing infertility treatment. Similarly, because data
\nfrom large, high-quality studies continue to accumulate, the evidence of a potentially
\ndeleterious effect of moderate alcohol and caffeine intake on the ability to become
\npregnant seems less solid than it once did. While a complete picture of the role of
\nnutrition on fertility is far from complete, much progress has been made. The most salient
\ngaps in the current evidence include jointly considering female and male diets and testing
\nthe most consistent findings in randomized trials.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-8992","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Departments of Nutrition (Drs Gaskins\r\nand Chavarro) and Epidemiology (Dr Chavarro),\r\nHarvard T.
