2/ It lowers your blood pressure

Just 30kcal of dark chocolate per day (two squares of a little Green & Black’s 70% bar) can lower your blood-cuff stats, found a German study at University Hospital of Cologne, Germany.

3/ It boosts your staying power

Leeds University researchers looked at the total antioxidant content of the nation’s three favourite chocolate flavours. Here’s how the bars stack up in terms of procyanidins, a heart-healthy flavonoid:

White: 0g
Milk:
 40.6mg per 100g 
Dark: 
93.5mg+ per 100g*
