Yes. Of course, there is the obvious one that no Starbucks-loving woman likes to hear—and that is caffeine. Studies show that even 300mg daily (the amount in one cup of coffee) can decrease your chances of conception. Alcohol is another one that should be eliminated completely when trying to conceive. In addition, high-fat foods and refined sugars/processed foods are minimally nutritious and often add extra pounds that can impact fertility. New studies are also showing that even the types of fats we eat contribute to how well an egg can fertilize and influence our conception rates. Although these are general guidelines, women with specific reproductive disorders such as endometriosis and PCOS each have specific foods that will improve their condition—as well as foods that can sabotage the healing process.
