Eat plenty of...
Whole grains: Oats, bran cereal, whole-wheat bread, and other carbs with a low glycemic index help regulate blood glucose and insulin levels, which is thought to aid fertility.
Vegetable protein: Dr. Chavarro has found that women with a higher intake of protein from soy and other plants (such as beans and nuts) are less likely to have problems with ovulation.
Leafy greens: They're rich in folate. Dr. Chavarro has discovered that women with the most folate in their diet are the least likely to have cycles in which they don't ovulate.
Beans: In addition to protein, beans and lentils are chock-full of iron, a nutrient that's associated with a reduced risk of ovulatory infertility.
Cut back on...
Trans fats: Many fried and packaged foods contain trans fat, which can increase your risk of infertility. (Avoid products with "partially hydrogenated oils" in the ingredients list.)
Soda: A 2012 study revealed that women who drank three or more sodas a day had a 52 percent lower likelihood of getting pregnant than those who drank none.
Alcohol: It's smart to start cutting back even before you get pregnant: Danish scientists reported that having as few as five drinks a week can affect fertility.
Meat: Adding just one serving a day of meatâincluding chicken, turkey, or red meatâis linked to a 32 percent increased risk of infertility, per Dr. Chavarro's research.
