There are some studies which shows that what you eat can help increase your chances of getting pregnant.
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:
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.
