A purple potato which is healthier than the standard variety is launching in supermarkets this week.

Called the 'Purple Majesty', the potato contains up to 10 times the level of the antioxidant anthocyanins when compared with the white variety.

Dr Catherine Tsang said: "We're all aware of the stories about red wine having a more positive effect on the heart than white wine, due to their higher levels of antioxidant.

"The same thing applies to purple potatoes. Anthocyanins have potent antioxidant properties and studies have shown that it has a positive effect on blood vessels and reducing blood pressure."

As shoppers find the vegetable on the shelves from this week, we take a look at other foods that are suprisingly good for you.
