Plain Greek Yogurt
Why to try: Female foodies have gone gaga over Greek yogurt for its bone-building calcium, but it may also help prevent iodine-deficiency-related infertility, fetal intellectual disabilities and other birth defects. An essential mineral for healthy thyroid hormone levels and reproduction, there is enough iodine in a single cup of plain Greek yogurt to fulfill half the iodine needs of most healthy women or one-third of those required to help prevent complications during pregnancy.
How to try: Swap Greek yogurt for mayo in your Caesar salad dressing. Just mix 1/3 cup non-fat plain Greek yogurt with the juice of 1/2 lemon, 2 tbsp olive oil, 1 crushed garlic clove, 1 or 2 minced anchovies, 2 tsp Worcestershire sauce and 3 to 4 tbsp Parmesan cheese and toss with chopped romaine and baked croutons.
