Fertility and diet: Is there a connection?

May 2018
Harvard Health Publishing
A new study of fertility and diet Researchers from the Harvard T.H. Chan School of Public Health and Harvard Medical School have just published a review of past studies that examined the impact of diet on fertility. Here’s what they found. For women trying to become pregnant naturally (without “assistive reproductive technologies” such as in vitro fertilization), the following vitamins and nutrients were linked to positive effects on fertility: folic acid vitamin B12 omega-3 fatty acids healthy diets (such as the Mediterranean diet) On the other hand, antioxidants, vitamin D, dairy products, soy, caffeine, and alcohol appeared to have little or no effect on fertility in this review. Trans fat and “unhealthy diets” (those “rich in red and processed meats, potatoes, sweets, and sweetened beverages”) were found to have negative effects. Studies of men have found that semen quality improves with healthy diets (as described above), while the opposite has been linked with diets high in saturated or trans fat. Alcohol and caffeine appeared to have little effect, good or bad. Importantly, semen quality is not a perfect predictor of fertility, and most studies did not actually examine the impact of paternal diet on the rate of successful pregnancies. For couples receiving assisted reproductive technologies, women may be more likely to conceive with folic acid supplements or a diet high in isoflavones (plant-based estrogens with antioxidant activity), while male fertility may be aided by antioxidants.
