Hiding between the fiber-rich bookends is a pregnancy-power-packed filler. Chicken is full of protein, which gives you energy and is a crucial building block in your baby’s overall development (particularly his or her brain). This sandwich also provides niacin, a B vitamin that aids digestion, promotes healthy skin and bolsters nerve cell development. Tomatoes boast vitamins E, A, C, K and folate, a nutrient that helps prevent neural-tube disorders, such as spina bifida.
Pair it with Greek yogurt (half the sugar and double the protein of regular yogurt) and a banana for a blast of potassium; unavailable in most prenatal vitamins, potassium keeps blood pressure in check, Norback says. Greek yogurt also provides plenty of calcium for building strong baby bones and teeth, as well as probiotics, which help you keep a healthy balance of bacteria in your gut.
