Eggs are an important source of protein and choline: choline plays a key role in brain development, and it is often left out in large part of prenatal vitamins commonly available. It’s important, however, to consume the yolk, not just the whites, as that’s where choline is stored.
Eggs also contain folate, Vitamin B12, A, E, and E, as well as iodine and selenium. What’s more is, they’re quick and easy to cook, and a common staple already in many people’s diet!
