Superstition and junk science will recommend all sorts of foods to aid in female fertility. Although anecdotal evidence suggests that some of these will work, the best way for to increase your babymaking capabilities is probably to eat healthily.
What to Expect suggest focusing on key areas to aid with the babymaking. Prenatal vitamins are solid supplements, but the bulk of your nutrition should come from your meals. Aim for three daily servings of calcium, as well as zinc (found in beef, lamb, pork, oatmeal and several other foods) and manganese (it’s in spinach, carrots and broccoli, among other veggies).
On the other side of the coin, heavy use of caffeine and alcohol can possibly hinder your fertility.
