Beet
Beets, in their royal purple, are loaded with goodies, and are a great source of energy for the body. They are high in sodium, magnesium, calcium, iron and phosperous. They are also a fiber food and are high vitamin A, vitamin C and niacin - they are amazing, especially considering they are quite cheap. Just put them in the fridge for a few hours and you've got a very healthy snack.
