The beetroot in this delicious tart is a rich source of antioxidants, including betacyanin, the pigment that gives beetroot its colour.
Beetroot also contains magnesium, manganese, sodium, potassium, phosphorus, soluble fibre, calcium, iron, vitamins a, B and c, folic acid and betaine — a powerful compound, which, among other things, enhances the production of our body’s natural mood-enhancer, serotonin.
But it is beetroot’s high level of nitrate that helps lower blood pressure and earns it the title of a superfood.
