Your fertility diet

Switch protein sources: Replace some of the beef, pork or chicken you eat (animal protein) with vegetable protein sources, such as cooked dried beans and nuts. When five percent of total calories which is eaten come from vegetable protein instead of animal, the risk of ovulatory infertility drops by more than 50 percent. Don't forget your vitamins: Women in the study who regularly took iron supplements and multivitamins containing folic acid had less ovulation-related infertility.

Consume choline: You may never have heard of it, but choline is a nutrient with the potential to reduce harmful gene effects that may result in birth defects. It also is important for brain function, among other benefits. Most women don't get enough choline; many prenatal vitamins don't even contain it. Egg yolks are rich in choline; only beef liver contains more. Cauliflower, the highest choline-containing veggie, has 25 percent of the choline found in one egg yolk.

Fish carefully: Don't eat sushi or any raw fish. Avoid fish that have high mercury content due to their environment including swordfish, tilefish, king mackerel and shark. Cut caffeine: High caffeine intake interferes with conception. You may want to consider eliminating it from your diet altogether by avoiding caffeinated coffee, tea and soft drinks (decaf is fine). Once you're pregnant, caffeine also crosses the placenta and can affect the fetus and even cause miscarriage.
