Beetroots are highly nutritious root vegetables that are a great source of vitamins and minerals, such as potassium, sodium, iron, phosphorus, magnesium, calcium, vitamin C and B vitamins. Rich in antioxidants, beets get their deep colour from the betalain pigment, which has potent anti-inflammatory properties. They are a great source of dietary fibre. Red beetroots also have a significant amount of iron.
