Beets are rich in the B vitamin folate, which is essential for cell growth, especially during pregnancy. One cup of cooked, sliced beets has 136 micrograms of folate. The daily requirement is 400 micrograms (800 micrograms during pregnancy). The greens attached to beets are also rich in nutrients and can be prepared like spinach or Swiss chard for a delicious side dish.
