Beets are awesome. You can even use them to dye your hair.
But beets are good for cleaning the blood, have vitamins A, B1, B2, B6, and C. The greens are also loaded with iron (more-so than spinach). The root itself is a great source of choline, folic acid, iodine, manganese, organic sodium, potassium, fiber and carbohydrates.
My favorite recipe is homemade borscht which I got from my grandma. Uses potatoes, beef, the whole beet (root and leaves), carrots, onion, and celery. Dice and brown the beef, toss in a pot with the diced vegetables, top with water, add salt, pepper, garlic powder and some onion powder, cook until vegetables are softened. You can blend it up or leave as is. Serve with sour cream. I try to make it the night before I give blood and have after I do give and I feel great.
