Beets are nutrient-dense.  Beets have many positive effects on our bodies. What does this mean for you:  nutrient-dense basically means that an item contains a lot of nutrients & is low in calories. I want you to know that 1 small beet– is around 35 calories, contains about 7g of carbohydrates, & contains almost NO FAT! Beets are rich in magnesium, fiber, and betalains.
