Beetroot is a low calorie food which makes a colourful addition to a salad. Pickled beetroot in jars is usually available in baby beet form, or as whole beetroot, sliced or crinkle cut. Unsweetened pickled beetroot can have quite a sharp tang, which sweetened varieties help to subdue. Although sweetened beetroot does have sugar as an ingredient, it doesn't make a great difference to the overall calorie count.
